egg and vinegar experiment ingredients

Place the treatment containers somewhere they can sit for at least a day at room temperature. Observe any changes that occur in the eggs during the first hour or so of soaking and record your observations.

Observe any changes in the color, size, or shape of your experimental eggs. Record your observations. Then, gently remove your sample eggs from their treatments to measure and record the mass of each one (see photo below). Remove the plastic wrap from the control egg and measure its mass too. Calculate the percentage change in mass for each egg by dividing the final mass by the starting mass and multiplying by one hundred percent.

In a separate bowl, carefully dissect the egg by piercing the membrane. Record your observations.

How did each egg change? Did its mass increase or decrease? Do you see anything in common with the treatments that enlarged the eggs? Which treatments made the eggs shrink, and which did not?

In general, the most dramatic changes to the mass, color, and shape of the eggs will occur within the first 24 hours of the experiment. Eggs submerged in corn syrup will have lost considerable mass and have the appearance of flabby sacks. Eggs soaked in distilled water will gain mass and appear dramatically swollen. Eggs in dilute salt solutions will gain mass, and even those in very concentrated solutions might gain mass. Eggs buried in salt or other dry media should lose mass.

The de-shelled eggs serve as good models of human cells. After the eggshell is removed, a thin membrane (actually, two membranes held tightly together) remains. This membrane, like those in human cells, is selectively permeable, allowing certain substances to pass through while blocking others.

Substances that can pass easily through the membrane of the egg will follow the principles of diffusion. They will move through the membrane from the side where they are at a higher concentration to the side where they are at a lower concentration (click to enlarge the diagram below). This movement will continue until the concentration on both sides is the same. While random molecular motion will cause individual molecules to continue moving back and forth across the membrane, the overall concentration on each side will remain in equilibrium, with equal concentrations on both sides.

The egg’s membrane is permeable to water. Movement of a solvent (such as water) across a semipermeable membrane from a less concentrated solution to a more concentrated one is called osmosis . When an egg is soaked in a solution that has a higher solute concentration (the relative amount of dissolved stuff) than the solute concentration inside the egg, water moves out of the egg and into the solution (see diagram below).

As a result, the egg loses mass and ends up looking deflated. An egg naturally has a lot of stuff inside, so the outside solution has to be very concentrated for this to happen. That’s the case when an egg is treated with corn syrup or buried in salt. By contrast, when an egg is treated with distilled water, or a dilute salt solution, the solute concentration is higher inside the egg than out, so the water moves into the egg, increasing its mass. It may be easier to think about osmosis in terms of water concentration rather than solute concentration. If the solute concentration is high, then the water concentration will be low by comparison.

Rubbing, or isopropyl, alcohol is at least 70% alcohol and therefore less than 30% water. This should cause water to move from the egg into the solution, and the egg should lose mass. In addition, the egg may appear white and rubbery. Alcohol that diffuses into the egg can denature the proteins, unraveling their three-dimensional structure and causing them to coagulate or join together. Egg proteins turn from translucent to white when they are denatured. In cooking, temperature is used to denature these proteins, but you may have noticed that alcohol has also "cooked" the egg and caused it to look hard-boiled.

The plasma membranes of your cells behave much like those of the egg. All of the trillions of cells in your body are like busy seaports with materials coming in and going out. Water, oxygen, and nutrients must pass through the plasma membrane into your cells, and wastes must leave. When the concentration of oxygen is higher in your lungs than it is in your blood, for example, the oxygen diffuses into red blood cells through capillary walls. Your flowing blood then transports that oxygen to your tissues. From there, the oxygen diffuses into other cells to be used in cellular respiration. Through a similar process, water in the stomach moves into the bloodstream and is then carried to the cells, where it supports a variety of essential bodily functions.

Predict what would happen if you placed the shrunken eggs in plain water overnight. Do the experiment and explain your results.

In this activity, not only can you measure how much material moved into or out of a treated egg, but you can also chemically determine whether molecules moved across the membrane. If you break the egg into a dish, or save some of the soaking solution, you can use chemical tests to see what’s there. For example, you can use Benedict’s solution to test for simple sugars, iodine to test for starch, or Biuret solution to determine whether or not protein exited the egg as it soaked.

When using this activity with large groups of students or multiple classes, have each group apply only one treatment, and then analyze the data collected from all groups. Having each small group design an experiment with one egg will allow you to do the activity with fewer eggs per class, and collecting several sets of data will enable students to identify any outliers.

This Snack is an excellent activity for introducing diffusion, osmosis, and the semipermeability of membranes and allows learners to engage in the NGSS Science and Engineering Practices. By collecting data from multiple classes, you can facilitate a discussion about what and how much data is necessary to count as evidence. Students can also use the evidence about what and how much material moves into and out of the egg to formulate a revisable model about how osmosis occurs and what might prevent or allow molecules to move through membranes. By incorporating related activities, such as the Cellular Soap Opera Snack, students can form a more complete conceptual model of the cell membrane and how molecules move along concentration gradients.

Note that it’s also important to discuss the idea that models such as this one have limitations. There are structural differences between the membranes of chicken eggs and human cells that result in differences in permeability. Some of the molecules that pass through the egg’s membrane in this activity would not pass through a human cell membrane because of their size (such as cornstarch) or their charge (such as Na + and Cl - from the salt).

Easy Egg in Vinegar Experiment

One of our favorite science experiments to do at home with kids is the egg in vinegar experiment! This rubber egg science experiment is a lot of fun for kids of all ages and it is a highly visual science experiment that is exciting for kids. Keep reading to learn how to do the experiment and to read about the science behind the egg in vinegar experiment!

Be sure to check out my Fizzy Egg Dyeing Science Experiment – The Best Way To Dye Easter Eggs as well!

Follow along with these directions to learn how to make a rubber egg!

All the details on how to complete the naked egg experiment from start to finish are listed below, including supplies too.

Here is what you need to complete this science experiment:

• Regular eggs (raw white eggs)
• White Vinegar
• Clear cup, mason jars, or other container (plastic or glass will both work)

What happens when you put eggs in vinegar?

This is what this simple experiment is going to show! The combination of the vinegar with the raw eggs and water is nothing sort of “magic”. This is one activity that does an amazing job of combining learning and fun in a way that will keep the kids engaged and ready for more.

Video of the rubber egg experiment

The science behind the naked egg science experiment.

When you place a raw egg in vinegar, the shell will dissolve overnight, exposing the membrane of the egg and the yellow yolk inside the egg.

The shell dissolves because of the acidic nature of the vinegar which triggers a chemical reaction with the shell of the egg.

Eggshells are made from calcium carbonate, which is a base. The acid in the vinegar (acetic acid) reacts with the calcium and breaks down the eggshell overnight. The acid in the vinegar reacting with the calcium carbonate in the shell produces Carbon Dioxide gas (co2.)

After the shell dissolves, the membrane of the egg remains. This is called a “semipermeable membrane” because the membrane can absorb some water.

Have the kids compare the size of the naked eggs with a shelled egg to see how the membrane absorbed some of the water from the vinegar and became larger.

The flow of water through a semipermeable membrane is called “osmosis.”

Directions for the Egg Soaked in Vinegar Experiment

Place 1-3 eggs in a clear container. Be careful not to crack the eggshell or the experiment might not work properly.

Pour enough vinegar over the eggs to cover them. You can add food coloring to the vinegar if you like.

Place the solution in an out-of-the-way place. While the egg sits in the vinegar some of the water in the vinegar will travel through the egg’s membrane

Check on the eggs in about one hour. You should see bubbles forming on the outside of the shell.

At the end of the day, stir the eggs gently with a spoon to help release the shell from the egg.

The next day, check on the eggs. The shell will appear as scum on the top of the vinegar.

Take out the egg and inspect it. You may have to gently rub it to remove the last bit of the shell.

If the shell comes off easily, the egg is ready to inspect. If not, put it back in the vinegar and remove it the following day.

Rinse the egg carefully with cool water to remove any shell residue.

Another variation on how to do the activity:

• Place the egg in vinegar
• After 24 hours change the vinegar. Drain the old vinegar carefully then add the fresh vinegar.
• Place the egg in vinegar in the refrigerator untouched for 7 days. After 7 days, pour off the vinegar, rinse the egg, and the shell will be gone. All you will be left with are naked eggs.

Inspect the egg under bright lighting to see the parts of the egg. Gently squeeze the egg to test the strength of the membrane!

The kids will love this rubber egg experiment! We also refer to this as our bouncy egg experiment because it does have a little bit of bounce to it, too!

What to do with the rubber egg

Do a bouncing eggs chemistry experiment. Can your rubber egg bounce?

Try placing your naked egg in a glass filled with corn syrup. The egg will shrivel up. The reason for this is that corn syrup has a lower concentration of water than the egg does. The water in the egg moves through the membrane into the corn syrup in order to equalize the water concentration levels on both sides.

Fun Ideas To Extend this Rubber Egg Activity

The fun part about creating science at home is that you can easily try out other hypotheses and ideas. Use this STEM activity as a way to get the kids to think outside the box. Talk to them about what they think is going to happen if other liquids are used and have them write out their thoughts.

Even if you don’t actually do the activity, this will show them the process of how a scientist’s mind works!

I hope you enjoyed this fun science activity. Simple science experiments are a great way to encourage curiosity in children by asking them questions, asking them to make a hypothesis on what will happen and will encourage further exploration.

Experiment on Putting an Egg in Vinegar

Osmosis Egg Experiments

The shell of an egg consists of mostly calcium carbonate, while vinegar is just acetic acid. Combining these two materials provides a great example of an acid-base reaction. The acid (vinegar) and base (eggshell) react to produce carbon dioxide, water and dissolved calcium. The experiment also provides a unique opportunity to view and handle a "naked" egg.

Place one or more eggs in a clear glass or plastic container large enough to easily accommodate the eggs.

Pour vinegar into the container, adding enough to completely cover the eggs. Observe the immediate interaction between the vinegar and the eggshell. Cover the container and put it in the refrigerator.

After 24 hours, carefully scoop the eggs out of the container, pour out the vinegar, return the eggs to the container, and add new vinegar to cover the eggs. Return container to the refrigerator.

After another 24 hours, scoop the eggs from the vinegar and rinse them with water. The eggshell will have dissolved away, leaving the flexible membrane still intact around the naked egg. Handle and examine the eggs, but be careful not to break the membrane or the raw egg will ooze out.

Things You'll Need

• There can be a second phase to this experiment. Once the eggshell has fully dissolved, the egg's semipermeable membrane remains. This membrane allows water and air to pass through, permitting a good demonstration of osmosis, as water passes through the membrane but larger molecules do not. Place one de-shelled egg in corn syrup and one in water, and observe the movement of water into or out of the egg. Putting the egg in corn syrup causes it to shrivel up, while submerging it in water has the opposite effect.
• Handle the egg and vinegar carefully, above an easy-to-clean surface, and wear a protective apron or old clothing, as well as safety goggles, when working with the vinegar.

How to make bouncy and glowing Egg

What can we do with an egg great omelet for one but did you know that this frail-looking egg is actually very durable  we will show you how to explore its properties and make a fun toy out of it in this cool egg in the vinegar experiment, article contents.

If you are looking for some fun and easy kitchen science experiment, the naked egg experiment is the right one for you. It has a great teaching power and your children will learn a lot about how cells in all living organisms work. All we need is some common kitchen supplies and we will be able to look inside of an egg, see what hides behind that thick shell and play some fun games afterward.

Anatomy of an Egg

The main parts of an egg are a shell, membrane, albumen (egg white) and yolk . 

Eggshell is made primarily out of calcium carbonate crystals (95-97%) which are connected by a protein matrix. That protein matrix gives strength to a shell, without them shell could break apart. Eggshell is protecting an egg from mechanical damage but also bacteria and dust.

The membrane is made out of proteins and it protects the inner part of an egg from bacterial infections. There are actually two membranes: outer and inner and they are surprisingly strong.

Albumen or egg white consists of 40 different proteins in addition to water (90%). Its main purpose is to provide additional nutrition to the embryo as well as protecting it. The yolk is the main source of nutrition for an embryo. It consists of proteins, vitamins, minerals, fat and some water.

The science behind the naked egg experiment

If we soak an egg in vinegar, we will start an acid-base reaction. The acetic acid from vinegar reacts with calcium carbonate (base) from an eggshell. Products of that reaction are calcium acetate, water , and carbon dioxide . 

You can notice bubbles forming on the eggshell surface, that’s the sign of newly created carbon dioxide. After some time, the shell is completely dissolved and all that keeps an egg together are its membranes.

After the hard, outer shell is dissolved, the egg becomes translucent (hence, the name “naked egg”) and when we put an egg on the source of light, it looks like it’s glowing and we can see the yolk inside. All that is keeping the egg together is a thin membrane called a semipermeable membrane.  

This is important for the next side effect of putting the egg in vinegar. You will notice how an egg becomes a little bigger. That is because of some of the water in the vinegar solution (even the strongest household vinegar is made from more than 80% of water) traveled trough the egg semipermeable membrane to equalize the concentration of water inside and outside of the egg. The process of water traveling through a semipermeable membrane is called osmosis and is characteristic of all living beings.

On the other hand, if we put our naked egg into corn syrup, the egg will shrink. That is because corn syrup has a lower concentration of water and water would move from inside of an egg to equalize the water concentration.

If you are interested in watching how we did it, check the video for making the bouncy egg at the start of the article. Or if you prefer reading, continue with step by step instructions below.

Materials needed for naked egg experiment

• Source of light (flashlight, mobile phone)

Instructions for bouncy glowing egg

• Carefully put an egg into a glass.
• Pour vinegar over it, it should cover an egg completely. Instead of vinegar, we can use cola, rubbing alcohol or orange juice since they are acidic enough. They should produce the same effect. Leave it for at least 24h, depending on vinegar strength (9% takes 24h). If the egg is fresh it will probably rise up, so try to rotate it gently using a spoon. 
• After 24h, remove an egg from the solution. Rinse it with water.

Congratulations! You now have a rubbery, transparent egg. This is also commonly called the naked egg.  Experiment with it! How high can it bounce? Can it survive 1m fall? We advise you to do your experiments outside! 🙂

If you put your naked egg on the source of light, you will see a cool glowing egg! In addition to that, you can investigate the anatomy of an egg, since you can see parts of an egg very clearly through the transparent membrane.

The Great Vinegar Eggsperiment

in Activities , Toddler Zone on May 1, 2018

Did you know that it’s possible to dissolve an eggshell from an egg, enlarge the egg a little a bit, and make it bouncy (without hard-boiling)…all with a simple experiment? I had absolutely no idea that you could manipulate a raw egg in such a manner…at least, not until we conducted The Great Vinegar Eggsperiment!

This amazingly cool science experiment is incredibly easy to setup, and it only requires two ingredients (that you likely already have in your kitchen). All you need is vinegar and eggs (and some glasses or jars to contain them) – that’s it! You can also add a bit of food coloring, to jazz things up a little bit more.

While the setup is simple, this experiment does require a bit of patience…it takes approximately 48 hours for the eggs to transform. That being said, the extra wait is totally worth it! Once you rinse the remaining eggshell remnants from your eggs, and realize that you are actually holding a fully-contained raw egg in your hand…you won’t be able to hide your excitement and sense of childlike wonder! It could easily be said that I was more enthralled with this experiment than our little nugget, although she thoroughly enjoyed eggsploring all the magic that eggs have to offer.

I still can’t believe how squeezable and squishy the shell-less eggs really are, or how much bigger they become, compared to their original size. Perhaps the most astonishing result of this little experiment, is the fact that the eggs take on a rubber-like quality, making them bouncy! Now, when I say bouncy, I don’t mean that you can drop the egg from arm-height and watch it bounce all over the floor (like a bouncy ball). But…you can drop it several inches above a flat surface, and it will in fact bounce. Part of the experimental fun, at least for us, was testing just how high we could drop the egg before the membrane finally broke and the yolk came spilling out! We determined that if you drop the egg anywhere above 8-10 inches, you’re in for a bit of a mess. 🙂 A fun mess, no less!

Speaking of which, I should probably add a little word of warning – when you drop your egg, it could unexpectedly bounce right off of the table, as witnessed in the video below:

In all honestly, we have probably watched this video more than a hundred times. And we all laugh out loud, each and every time! So, just to be clear, messes can most certainly be made with this eggsperiment, but they are always easy to clean up. And you never know…you just might get a funny blooper video out of it too. 🙂

• Distilled White Vinegar
• Small Drinking Glasses/Jars
• Food Coloring (optional)

Instructions:

• Start by filling the glasses/jars with vinegar. You will need one glass, per egg. If you would also like to experiment with dying the egg membranes a different color…feel free to add a few drops of food coloring to the glasses of vinegar. We kept one glass clear, dyed one blue, and the last one purple.
• Carefully add an egg to each glass.
• Set aside for approximately 48 hours. I’m not a huge fan of filling my house with the smell of vinegar, so I covered each of our glasses with plastic wrap, to reduce the odor.
• Once the eggs have been sitting in the vinegar for two days, bring them over to the kitchen sink. Gently pour an egg into your hand. There may still be a few particles of eggshell stuck on the egg. If you run the egg under cold water, while gently rubbing the exterior with your fingertips, you will remove any remnants of the original eggshell. Set the egg down on a paper towel. Repeat the process for the remaining eggs.
• Once all of your eggs have been rinsed, grab a tray (or cookie sheet) and let the fun begin! 🙂

Before I handed our daughter one of the shell-less eggs to explore, we sat down to examine a normal raw egg. I wanted her to hold a standard egg…to feel the hardness of the shell…to judge its size. I asked her if she thought it would bounce if she dropped it…and then we tested her hypothesis. As you already know, it did not bounce. The eggshell cracked open and the egg started seeping out. Exploring and examining a raw egg is fun, in and of itself!

Once we had tired of playing with our raw egg, it was time to check out our shell-less vinegar eggs! The colored eggs were definitely a highlight with our little nugget, even though our purple egg had turned a shade of blue.

By now, you may be wondering how all of this really works. What’s the scientific explanation? Well, when the eggs are in the vinegar, you will notice small bubbles forming on the eggshell. The bubbles are carbon dioxide. The carbon dioxide is a result of the reaction between the vinegar (acetic acid), and the eggshell (calcium carbonate). Carbon dioxide is not the only product of the reaction, calcium acetate and water are also created. With the calcium carbonate depleted, what remains is a thin, translucent layer called the semipermeable membrane.

How do the eggs grow larger in size? The white vinegar that you buy from the grocery store is typically made up of 4% acetic acid, and 96% water. The eggs grow in the vinegar, because the water in the white vinegar can travel through the egg’s membrane. The water moves through the semipermeable membrane in order to equalize the concentration of water on both sides of the membrane. This process is called osmosis.

Did you know that if you placed your vinegar egg into a glass full of corn syrup, that the egg would shrink and shrivel? Corn syrup has a lower concentration of water, so in order to create a balance in water concentration, water would be drawn out of the egg membrane and into the corn syrup. Seriously, science is SO cool!

Have you tried this vinegar eggsperiment with your kiddos before? Were they amazed? Were you? I think this will most certainly be one of those experiments that we repeat!

Egg in Vinegar Experiment

Did you know you can study cells by examining eggs? Chicken eggs are essentially one big cell making it much easier to study than the teeny tiny cells that make up our body. With this cells unit study on cells we examined raw eggs to learn about their parts. This was a great introduction into the concept of the cell, but we decided to take our study of the egg up a notch. It was time to do an egg in vinegar experiment and the always fun rubber eggs study.

Naked Egg Experiment and Cell Study

Turn off any adblockers to ensure our video feed can be seen. Or visit our YouTube channel to see if the video has been uploaded there. We are slowly uploading our archives. Thanks!

To start off our unit study we discussed cells and how they make up all living things. Then it was time to get hands on! We decided to bring some chemistry to our biology lesson and do a simple experiment – the egg in vinegar experiment.

This science experiment has a few names: Rubber Egg Experiment, Bouncy Egg Experiment, Naked Egg Science Experiment or Egg in Vinegar Experiment. No matter what you call it, this is one of our all time favourite simple science experiments. And it pairs perfectly with an egg cell study.

With this experiment we remove the shell of a raw egg with a chemical reaction, leaving us with a naked egg. The inside of this naked egg provides an excellent opportunity to study cells.

Here is a Quick Video Showing the Process

Hands on exploration .

We kicked things off with each child taking an egg and exploring. We encouraged their curiosity as they explored the shell, how fragile the eggshell is, and what it looks like when cracked open.

Surprisingly, we were able to remove some of the shell from one of our eggs revealing the membrane! This made the kids even more excited about our experiment to create naked eggs.

To remove the shell of a raw egg we need to do a little chemistry experiment. For this you will need:

• Eggs (regular eggs are perfect)
• White Vinegar
• Mason Jars (other wide mouth jars or plastic cups work too)
• Food Colouring
• Large plates or bowls

Extra items you may want available for further investigations:

• Magnifying glass
• Kitchen scale
• Fabric tape measure
• Towels or protective covering for the area while exploring with the naked eggs

Start by testing to make sure your eggs will easily fit into (and out once enlarged) easily. I recommend using wide mouth mason jars for at least one of the eggs so kids can really see the reaction. But if you want to do lots of eggs you can do them in large plastic cups or even do big batches in large bowls.

I recommend doing extra eggs. Some may not survive the experiment and even once the shells are removed the membranes are still quite thin and easy to break. Having lots of naked eggs will provide kids with plenty of opportunity to explore and learn with the resulting bouncy, rubbery eggs. 

Set the egg carefully in the container, pour vinegar over the egg until it is submersed. The egg may float, this is OK. Add a little food coloring to the vinegar. Now let it sit for 24 hours.

Bubbles form immediately on the shell as the chemical reaction begins. These carbon dioxide bubbles are formed by the vinegar reacting to the calcium in the egg shell.

After about 24 hours you will end up with foam on top of your vinegar and the remaining liquid is mostly water. You will end up with a foam on top and eventually you will have only liquid water left.

After 24 hours drain off the liquid and replace with fresh vinegar. You can also add more food colouring if you wish. It is very important to replace the vinegar to ensure there is enough acid for the chemical reaction to finish.

Tip – Getting Vibrant Colours

To get really vibrant colours in your Bouncy Eggs, add a few drops of gel food colouring to the initial vinegar soak. Gel colouring is much more intense in colouration. Then let it soak for 24 hours.

We then soaked our eggs in plain vinegar for the second soak. And our eggs came out very saturated in colour.

What is the Chemical Reaction When You Place an Egg in Vinegar? 

Here is the chemical reaction:

CaCO 3 + 2 HC 2 H 3 O 2   →  Ca(C 2 H 3 O 2 )2 + H 2 O + CO 2

To break this down you have:

Egg Shell (Calcium Carbonate) + Vinegar (acetic acid) → Foam Floaties + Liquid Water + Carbon Dioxide Gas Bubbles

The result – naked eggs.

After another 24 hours (2 days in total) your naked eggs should be ready! Carefully drain off the liquid and rinse your eggs under a gentle stream of water.

The membrane of the egg is still quite thin and fragile. So handle with care and do it in a place that is easy to clean!

Studying Naked Eggs

Start by letting the kids handle the eggs. their curiosity should lead them to lots of neat discoveries. Some questions you can ask are:

• What do you notice about the eggs?
• How do the eggs from the vinegar experiment feel compared to eggs still with their shells?
• Can you see anything moving inside? Try holding it up to a light or flashlight.
• How does the size of the naked eggs compare with eggs that have not been through the chemical reaction?

Why does the egg feel rubbery after being in vinegar?

Egg shell is basic and vinegar is an acid. When you place an egg in vinegar it reacts causing the shell to dissolve leaving only the rubbery membrane holding the egg together. If you are lucky enough to get some of the shell off a normal raw egg, you can see the membrane.

Bouncing Eggs

My kids had a great time bouncing eggs in a large bin. As long as you don’t add too much force, you can bounce a raw egg. So cool!

What can you see inside naked eggs?

Hold the eggs up to a flashlight or bright light and move the egg around or gently squeeze it. You should be able to see the yolk and other parts inside the egg floating around.

Why does the egg get bigger in Vinegar?

Did you notice the eggs are larger than before you placed them in the vinegar? This is why we recommend using a wide mouth jar. Otherwise your naked egg could get stuck in the jar! But why does this happen? It’s because of a process called osmosis. Through osmosis some of the liquid (water) moves through the semi-permeable membrane into the egg. It does this until it reaches an equilibrium between the amount of water inside the egg membrane and the surrounding liquid. If it didn’t stop at equilibrium the egg would get so large it would eventually pop! Since there is no hard shell to keep the egg small, it expands and grows.

Learn more about Osmosis with our Rainbow Water Beads Experiment or Gummy Bear Experiment .

Getting Inside – Studying Cells with Eggs

I recommend working over a large bowl or plate as kids explore the eggs. Undoubtedly, some will break. This isn’t the end of the world though, it just means it is time for some new lessons on cells.

If you don’t have any broken eggs take a knife or tooth pick and gently poke the egg to rupture the membrane.

The food dye travels through the membrane into the egg white (this is part of the osmosis process we discussed that also caused the egg to grow), but a special membrane around the yolk stops the dye from traveling into the yolk. This is a great visual for permeability and osmosis.

But closer inspection shows that some very special parts of our egg have taken in quite a lot of the dye. The chalaza, stringy bits on either side of the yolk that help to hold it in place, and the blastodisc, a circle in the middle of the yolk, this is where the sperm enters to fertilize the egg and is the nucleus of the egg (just like a cell!).

Dying the egg makes it much easier to see all these parts of the egg compared to when we just cracked open a raw egg. Now kids can see the cells and structures more clearly.

Digging Deeper Science Activities

This is such a fun experiment, why not take it further with some scientific investigative studies? Answer questions like:

What happens if you let the eggs soak in vinegar for a week instead of only 2 days? Compare the differences.

What happens if you boil the egg before placing it in vinegar?

What can you change in your experiment to make the resulting egg more bouncy and less prone to breaking?

Compare before and after. Take measurements, weights and work out how much the eggs changed during the experiment.

What happens if you take a naked egg and place it in corn syrup? (Tip! The result has to do with the process of osmosis).

Explore osmosis further… What happens if you soak a naked egg in water?

Don’t have time to do all of these experiments? Use your critical thinking skills and lessons learned from this experiment to predict what you think will happen. Create your hypothesis then do some research to see the answer when you have time, either by experimenting yourself or reading about experiments done by others.

Egg in Vinegar Experiment

Want to see a chemical reaction in action? With this egg in vinegar experiment, we observed and followed a regular egg through a transformation to become a bouncy egg. You can too with just a few repurposed ingredients you may have around the house for Easter!

This experiment allows you to see how two common household materials react — eggshell and vinegar. When these materials come in contact, a (safe) chemical reaction takes place and creates new compounds. This easy experiment is great for children to do on their own, and fun to observe how the egg changes over time.

Want to explore more kitchen science experiments? Explore the tastier side of learning with Science of Cooking: Ice Cream from the KiwiCo Store !

Ages: 5 - 11

Materials you'll need

Step-by-step tutorial.

Carefully put your egg into a jar and fill the jar about three-quarters full with the egg completely submerged in the vinegar.

You should be able to see bubbles form around the egg immediately. Where do you think they come from? Wait 48 to 72 hours. We found it exciting to check in on the egg as we went as the egg grows and changes over time.

After waiting, use a spoon to take out the egg. Carefully rinse it thoroughly under the faucet using warm water.

Your egg is now ready to bounce! Hold your egg about 3 inches from the table and gently let go. If bounced too hard the egg will break. This means you'll get to see the membrane of the egg!

Final result!

Compare your transformed egg to a regular egg. What do you think happened to the eggshell? What other differences can you observe? What's Going On? If you look closely at the egg while it's submerged in the vinegar, you can see bubbles forming on the surface. Those bubbles are full of carbon dioxide, just like the bubbles in a glass of soda. You're seeing a reaction between a compound in the eggshell (calcium carbonate) and an acid in the vinegar (acetic acid). This reaction creates carbon dioxide (and some other things) and breaks down the eggshell in the process. The membrane underneath the shell doesn't react, so it's left behind. Once the shell is completely gone, all that's left is the flexible membrane, giving you a bouncy "rubber" egg!

Egg in Vinegar Science Experiment – How to Make a Bouncy Egg

Mar 31,2023 by Edulab

Are you ready to take your egg game to the next level?

With a few simple supplies and a bit of patience, you can turn a regular raw egg into a bouncy ball-like object. This is a great experiment to do with kids or for anyone who loves a good science experiment.

Supplies needed:

• Glass or Jar
• White Vinegar

Instructions:

Step 1 – Get a raw egg and carefully place it into a glass or jar. Then fill the glass with white vinegar until the egg is completely submerge

Step 2 – Leave the egg in the glass for 2-3 days*. Each day, check back on the egg. Make some observations.

• Do you notice any changes to the egg?
• Is anything happening to the vinegar?

Write down your observations each day.

After about 3 days, the egg will start to become translucent, and you will know it is ready to move to step 3.

*You can speed up the process by changing the vinegar halfway through.

Step 3 – Carefully remove the egg from the glass and rinse it under some tap water. While rinsing the egg, gently rub the outside of the egg, and the white film will come off, leaving you with a translucent egg. Examine the egg and make some observations.

• Does the egg look different from when you started the experiment?
• Does the egg feel different?
• Perhaps you notice that it feels rubbery (like a bouncy ball).

Write down your observations.

Step 4 – Over a plate or other container, lift the egg 1-2 inches in the air, let go, and watch it bounce. Make some observations.

• What happens to the egg?
• Does it bounce?
• Is this different than what you expected?

Step 5 – When you are ready for some messy fun, lift the egg a little higher in the air and let it go… SPLAT!

So, what’s happening here?

The vinegar in the glass is acetic acid, which reacts with the calcium carbonate in the eggshell, producing carbon dioxide gas. The carbon dioxide gas creates the bubbles you see forming on the eggshell when you first place it in the vinegar. Over time, the reaction causes the eggshell to dissolve, leaving behind the egg’s membrane. This membrane gives the egg its rubbery texture, and the lack of a hard shell allows the egg to bounce like a ball.

In conclusion, the Egg in Vinegar Science Experiment is a fun and educational way to explore chemical reactions and the properties of eggs. Kids and adults alike will love seeing the transformation of a raw egg into a bouncy ball-like object. Just be prepared for a little bit of messiness!

Egg in Vinegar Experiment

The egg in vinegar experiment, though pretty simple, gives your child the foundation knowledge on reactions between acids and bases. It goes on to change the chemical composition of an egg, making it rubbery on being dipped in vinegar for a few days. There are minor changes in the size of the egg too which can be measured over the period and plotted in a graph.

Rubber Egg Science Project

On soaking an egg in vinegar, the liquid dissolves its hard shell while exposing the thin membrane that is the only thing that holds the egg yolk and white.

• White vinegar
• A clear jar or tall glass
• A big spoon
• Place the egg in the jar or glass such that it does not touch the walls of the container.
• Pour vinegar so as to cover the egg completely.
• Watch the egg closely. You should see bubbles forming on its surface. Note down your observations.
• Let the egg soak in the vinegar for one day.
• Use the spoon to scoop out the egg from the vinegar. You need to be very careful while doing this as the shell should already be partially dissolved by this time, leaving the egg tender.
• Now pour out the old vinegar, put the egg back in the container and cover it with fresh vinegar.
• Let the arrangement sit for another week.
• Scoop out the egg and rinse it carefully.
• Now you are left with an egg without a shell. Though it still looks like an egg, it has a translucent covering membrane that flexes when you squeeze it. If you shake it, you can see the egg yolk sloshing about in the egg white. You can even bounce it gently over hard surfaces.

Things You Can Try

• Perform the experiment on a hardboiled egg
• Try other variations of vinegar such as concentrated or apple cider vinegar. You can also replace vinegar with vinegar and baking soda solution, coke, corn syrup, salt water, tap water, etc. and look for any difference in the results.

Egg and Vinegar Experiment Video

Explanation for the bouncy egg.

Eggshells are made of calcium carbonate (chemical formula CaCO 3 ) while vinegar is acetic acid (chemical formula CH 3 COOH). The two chemically react to separate the calcium and carbonate parts. The calcium ions freely float in the vinegar while the carbonate ions form carbon dioxide that you can see in the form of bubbles.

Since the egg membrane is semi-permeable, it allows some of the vinegar to enter the interiors by osmosis, a process by which molecules of a solvent pass through a semi-permeable membrane to land themselves in a more concentrated solution from a less concentrated one. This makes the egg bigger and more delicate when you handle it. If the membrane ruptures, the insides of the egg will spill into the vinegar.  After the experiment, if you leave the nude egg exposed to air, the atmospheric carbon dioxide reacts with the leftover calcium in the egg to make it regain rigidity after some time.

In the lab, it can also be used as a tool to grow dental health awareness in children. Teachers can explain that a similar reaction occurs when the bacteria sticking to their teeth create acids on reacting with sweets or coke (soda) when they have it. Their enamels get destroyed in the process. The fun yet educative activity has all the ingredients to become a favorite science fair project.

Naked Eggs: Acid-Base Reaction

Activity length, 15 mins. plus 2-7 days, chemical reactions, activity type, discrepant event (investigatable).

In this activity, students describe the effects of an acid on an eggshell. The reaction of the eggshell in vinegar is an acid-base reaction . When you submerge an egg in vinegar, the shell dissolves, leaving the inner semi-permeable membrane intact.

Vinegar (acid) breaks apart the solid calcium carbonate crystals (base) in the eggshell into their calcium and carbonate parts. The calcium ions stay dissolved in the vinegar (calcium ions are atoms that are missing electrons), while the carbonate goes on to make carbon dioxide — the bubbles that you see.

The acidic vinegar leaves the membrane that lines the inside of the shell intact. Some of the vinegar permeates the membrane due to osmosis, which is why the egg swells. If you shake the egg, you can see the yolk sloshing around in the white. If the membrane tears, the contents will spill out just the same as with any raw egg, only now they have been "pickled" in the vinegar.

Teacher Tip:  Younger students may think that the outer shell has "transformed" into the membrane. Remind them that the outer shell and the inner membrane are two completely different layers. You can crack a raw egg to point out the layers.

Describe the effects of an acid-base reaction.

Identify common acids found in the home.

Per Group of 3–4 students: 1 raw egg (plus a few extras) vinegar (enough to cover an egg in a jar a jar or bowl slightly wider & deeper than the egg a large spoon a flexible measuring tape (like one used for sewing)

Key Questions

• When you first cover your egg with vinegar, what are the bubbles on the shell’s surface?
• What evidence is there of chemical change?
• What reaction is involved to make the shell dissolve?
• What is keeping the egg contents from spilling out?
• Is there a difference between the size of the egg at the beginning and at the end of the experiment? What has caused this change?

Preparation

Designate a “vinegar pouring station” at your desk so that you can monitor the amount of vinegar students are using (to avoid wasting).

Teacher tips: Repeat the same activity as your students to produce a couple of extra “naked eggs” to use as a control in the related activity Naked Eggs: Osmosis . Also keep the students’ naked eggs for this activity.

• Place the egg in a jar.
• Cover the egg with vinegar and store in a safe place. You should see bubbles forming at the surface of the shell.
• The next day, use the big spoon to scoop the egg out of the vinegar.
• Discard the old vinegar.
• Cover the egg with fresh vinegar and store in a safe place.
• Every morning, check on the state of the egg without taking it out of the jar, for about 2–7 days. You only need to replace the vinegar after the first day.
• After a week, the egg should be translucent but still pretty much egg-shaped.
• Measure the circumference of the middle portion of the egg.
• Do not break the egg unless your teacher says you can — you may use it in another experiment!
• Compare the effects of vinegar, plain water, cola, and orange juice on the eggshell. What do the three liquids have in common? How do they differ?
• Repeat the same experiment with a hard-boiled egg. The eggshell will dissolve in the same way, leaving behind a rubbery egg that should actually bounce as long as it is only dropped from less than 50 cm.

Egg in Vinegar Experiment | Removing an Eggshell Without Breaking the Egg

How do we normally remove an eggshell? If it is a raw egg, we just break the shell in one go. If it is a hard-boiled one, we break the shell in bits and pieces. But there is a way to break the shell of a raw egg with the egg remaining intact. This egg in vinegar experiment will explain how it can be done.

Materials Required

Raw eggs – 2 Glass container – 1 (should be big enough to put 2 eggs) Vinegar – enough to fill the container Water – 1 glass Corn syrup – 1 glass

Steps to Follow

• Pour vinegar into the container.
• Put both the raw eggs into the vinegar. Immerse the eggs completely in the solution.
• Keep the container for a day. Observe what is happening. Note down your observations.
• We can see tiny bubbles rising from the sides of the eggs. These bubbles are carbon dioxide formed due to the reaction between acetic acid and calcium carbonate.
• Take out the eggs after 24 hours. See if you can easily rub off the egg shell.
• If it is not possible, dip the eggs in fresh vinegar for one more day.
• Take out the eggs after another day. You will be able to wipe off the eggshell. You can see that the eggs have become translucent and rubbery. Hold them towards light, and you can see the yellow yolk inside.
• In the next stage of our experiment, we will see the effect of osmosis happening on egg.
• For this, dip one of the eggs in a glass of water. Dip the other egg in corn syrup.
• Leave both the glasses for a day.
• Examine the eggs after one day. The egg in the water has expanded.
• Examine the egg in the corn syrup. You will see that it has wrinkled and shrunk in size.

What we learn

What is the reason behind this transformation of egg? Eggshell is made of calcium carbonate, and vinegar contains acetic acid. When egg is soaked in vinegar, calcium carbonate reacts with acetic acid to release carbon dioxide. In this process, the entire shell is used up, and there remains the egg without shell. It still holds the shape because of thin membranes surrounding the inner part.

In the second stage of the experiment, we saw the effect of osmosis on eggs. When the egg is put in water, there is greater concentration of water outside the egg, than inside it. So water from the container diffuses through the semi-permeable egg membrane, into the egg.

The egg put in corn syrup wrinkles up after a day. This is because corn syrup has lesser concentration of water than the egg. So water diffuses from the egg to the syrup. Osmosis causes the movement of water through the semi-permeable egg membrane, from the area where water concentration is more to the area where water concentration is less.

How To Make a Baking Soda Volcano With Free Observation Sheet

This experiment will have kids erupting with applause!

The classic baking soda volcano experiment has been entertaining kids (and adults) of all ages for decades. But it’s more than just a lot of fun. This experiment also teaches kids about simple chemical reactions and physical properties. The best part? It’s easy to do and uses only a few basic ingredients. Read on to see how to conduct the baking soda volcano experiment, and fill out the form on this page to grab your free recording sheet!

How does the baking soda volcano experiment work?

This experiment involves pouring vinegar mixed with dish soap into a small amount of baking soda. The baking soda acts as a base while the vinegar is an acid. When the base and the acid come together, they create an endothermic reaction that produces carbon dioxide. The dish soap helps to create the foaming effect as the “lava” pours out of the volcano.

What does the baking soda volcano teach?

The baking soda volcano experiment is a great way to demonstrate a chemical reaction between an acid and a carbonate. When the carbonate (found in the baking soda) is exposed to the acids (found in the vinegar), it creates a decomposition reaction that releases carbon dioxide as gas. While this experiment is an example of an acid-base reaction, it’s also a great simulation of a real volcanic eruption.

Is there a baking soda volcano video?

This video shows how to make a volcano erupt using ingredients you can probably find in your kitchen.

Materials needed

To do the baking soda volcano experiment, you will need:

• Baking soda
• Food coloring
• Mini Paper Cups
• Plastic Volcano Form

Our free recording sheet is also helpful—fill out the form on this page to grab it.

Baking soda volcano experiment steps:

1. to start, place a tiny paper cup into the hole at the top of the plastic volcano mold..

2. Once your volcano is set up, pour 1 to 2 teaspoons of baking soda into the paper cup.

3. Next, add about a half cup of vinegar into a plastic measuring cup.

4. Add a few squirts of dish soap to the vinegar solution.

5. Add some squirts of red and yellow food coloring to the vinegar mixture.

6. Use a plastic spoon to mix all the ingredients in the plastic measuring cup together.

7. Pour the vinegar solution into the small paper cup at the top of the volcano.

8. Finally, watch and enjoy the eruption!

Grab our free baking soda volcano experiment worksheet

Fill out the form on this page to get your free worksheet. The worksheet asks kids to guess the correct order of the steps in the experiment. Next, kids must make a prediction about what they think will happen. They can use the provided spaces to draw what happens before and after they add the ingredients. Did their predictions come true?

Additional reflection questions

• What role does the dish soap play in the reaction that occurs?
• How would it be different if you added baking soda to the vinegar instead of the other way around?
• What do you think would happen if you added a different liquid than vinegar?
• What do you think would happen if you added more baking soda?

Can the baking soda volcano experiment be done for a science fair?

Yes! If you want to do this experiment for a science fair, we recommend switching up some of the variables. For example: Does the amount of baking soda matter? Does the type of dish soap? Form a hypothesis about how changing the variables will impact the experiment. Good luck!

How To Teach Science

Kids are curious and always looking to explore, discover, check out, and experiment to discover why things do what they do, move as they move, or change as they change! My son is now 13, and we started with simple science activities around three years of age with simple baking soda science.

Here are great tips for making science experiments enjoyable at home or in the classroom.

Safety first: Always prioritize safety. Use kid-friendly materials, supervise the experiments, and handle potentially hazardous substances yourself.

Start with simple experiments: Begin with basic experiments (find tons below) that require minimal setup and materials, gradually increasing complexity as kids gain confidence.

Use everyday items: Utilize common household items like vinegar and baking soda , food coloring, or balloons to make the experiments accessible and cost-effective.

Hands-on approach: Encourage kids to actively participate in the experiments rather than just observing. Let them touch, mix, and check out reactions up close.

Make predictions: Ask kids to predict the outcome before starting an experiment. This stimulates critical thinking and introduces the concept of hypothesis and the scientific method.

Record observations: Have a science journal or notebook where kids can record their observations, draw pictures, and write down their thoughts. Learn more about observing in science. We also have many printable science worksheets .

Theme-based experiments: Organize experiments around a theme, such as water , air , magnets , or plants . Even holidays and seasons make fun themes!

Kitchen science : Perform experiments in the kitchen, such as making ice cream using salt and ice or learning about density by layering different liquids.

Create a science lab: Set up a dedicated space for science experiments, and let kids decorate it with science-themed posters and drawings.

Outdoor experiments: Take some experiments outside to explore nature, study bugs, or learn about plants and soil.

DIY science kits: Prepare science experiment kits with labeled containers and ingredients, making it easy for kids to conduct experiments independently. Check out our DIY science list and STEM kits.

Make it a group effort: Group experiments can be more fun, allowing kids to learn together and share their excitement. Most of our science activities are classroom friendly!

Science shows or documentaries: Watch age-appropriate science shows or documentaries to introduce kids to scientific concepts entertainingly. Hello Bill Nye and the Magic Schoolbus! You can also check out National Geographic, the Discovery Channel, and NASA!

Ask open-ended questions: Encourage critical thinking by asking open-ended questions that prompt kids to think deeper about what they are experiencing.

Celebrate successes: Praise kids for their efforts and discoveries, no matter how small, to foster a positive attitude towards science and learning.

What is the Scientific Method for Kids?

The scientific method is a way scientists figure out how things work. First, they ask a question about something they want to know. Then, they research to learn what’s already known about it. After that, they make a prediction called a hypothesis.

Next comes the fun part – they test their hypothesis by doing experiments. They carefully observe what happens during the experiments and write down all the details. Learn more about variables in experiments here.

Once they finish their experiments, they look at the results and decide if their hypothesis is right or wrong. If it’s wrong, they devise a new hypothesis and try again. If it’s right, they share their findings with others. That’s how scientists learn new things and make our world better!

Go ahead and introduce the scientific method and get kids started recording their observations and making conclusions. Read more about the scientific method for kids .
