6th Grade Science Fair Projects

6th grade science fair projects can be fun as well as educational. The key to finding a good project idea is to pick one that can be completed in time, uses materials you can actually find, and incorporates the scientific method . You can turn any science project into a science fair project by finding one factor you can change (the independent variable ) and measuring its effect on another factor (the dependent variable ). Either predict what you expect to happen or form a hypothesis , record the data, determine whether it upholds the prediction, and report your findings.

Here is a collection of 6th grade science fair project ideas. The projects include chemistry, biology, physics, geology, weather, environmental science, and engineering.

Grow Geodes in Egg Shells

Geodes form when minerals crystallize from water trickling into holes within rocks. While natural geodes take millions of years to form, you can make your own geode in a few hours or days. Use an eggshell as your “rock” and crystallize salt, sugar, borax, or Epsom salts.

Make It an Experiment: Turn this cool project into a science fair experiment by predicting how temperature affects crystal formation. You can explore the effect of rate of cooling on crystallization by insulating the growing geode with a hot water bath, leaving it at room temperature, and refrigerating it.

Build a Structure to Withstand an Earthquake

Explore the principle engineers use to construct buildings to withstand seismic events like earthquakes. Use styrofoam plates as the “ground” and make buildings using craft sticks. Join the craft sticks to each other using mini-marshmallows. Use a sharp pencil to poke holes in the bottom of the plate to insert craft stick supports. These will be the building’s foundation. When you have finished construction, shake the plate from side to side to simulate an earthquake.

Make It an Experiment: What type of structure survives the simulate earthquake the best? Is it rigid or flexible. You can perform a similar simulation by constructing a structure meant to withstand a hurricane. Use a fan as the wind and examine how the type of wall affects the building’s stability.

Control the Rate of a Color Change Reaction

Many color change chemical reaction are clock reactions. What this means is that if you mix the same amounts of chemicals under the same conditions, the color change occurs after the same time interval (like clockwork). The blue bottle reaction and vanishing valentine are excellent clock reactions for 6th grade science projects.

Make It an Experiment: Predict whether changing the concentration of the starting chemicals or the temperature of the liquids will increase or decrease the speed of the color change. Perform the experiment, record the results, and see if you can explain them.

Turn Milk Into Plastic

Many common plastics come from petroleum, but you can make a plastic from milk . Basically, all you do is curdle the milk . Heat 1/2 cup of milk or heavy cream over low to medium heat until it simmers. Stir in lemon juice or vinegar until the mixture starts to thicken. Remove the pot from heat. When the liquid has cooled, rinse the curds with water. These curds are a natural casein polymer. You’ve made homemade plastic!

Make It a Science Experiment: Your experiment might explore the properties of this plastic, including how far it will stretch, how much weight it can hold, and whether it can be used as a modeling compound. Another option is to compare the amount of plastic you get from cow’s milk compared to goat milk or sheep milk. Do you get the same amount of plastic from cream as from milk?

Explore the Pigments in Leaves

Most leaves look green from chlorophyll, but actually contain several different pigments. In the autumn, plants make less chlorophyll, so you can see the other colors. You can use paper chromatography to see pigments in leaves. To do this, grind leaves to break open their cells (a blender works well), place them in a small jar, add just enough alcohol to cover the leaves, and insert a long strip of coffee filter paper into the jar. You want one end of the paper strip in the leaf mixture and the other end extending up and outside of the jar. As liquid moves up the paper, it pulls pigment molecules along. Smaller molecules move faster, while larger molecules move slower. Over time, this separates the colors.

Make It an Experiment: See if you can identify which pigments the leaves contain based on their colors. Gather leaves from a single plant from multiple seasons. Compare the pigments from spring, summer, and autumn. Can you tell the season by the pigments present in the leaves?

See the Iron in Breakfast Cereal

Use a magnet to separate the iron from breakfast cereal so you can actually see it. To do this, pour one cup of crushed cereal into a zipper-lock bag and fill the bag half full of warm water. Shake the bag to mix the contents and allow at least 20 minutes for the flakes to dissolve. Place a strong magnet against the side of the bag and slosh the contents around so the magnet can capture the iron. Finally, keep the magnet up against the side of the bag but tilt the bag so you can see the iron. It will appear as tiny black specks.

Make It an Experiment: Compare the iron in different cereals. Do all cereals contain about the same amount of iron? Does it look the same in every product?

Use Eggs to See Which Drinks Stain Teeth

Tooth enamel is the mineral hydroxyapatite (hydrated calcium phosphate), while egg shell is calcium carbonate. Egg shell is more porous than tooth enamel, so it stains more quickly. Soak eggs in tea, coffee, soda, and other liquids to determine which ones stain teeth. Common drinks also contain acids in addition to pigments, so some drinks dissolve egg shell (and teeth). Can you identify them?

Make It an Experiment: After staining the eggs, predict which methods work to remove the stains. Test these methods and see if you can discover how they work.

Use Household Chemicals to Clean Old Coins

Learn about oxidation, which includes tarnish, patina, and rust. Explore the cleaning power of common household chemicals. Soak discolored coins in soap, laundry detergent, lemon juice, salt water, soda, ketchup, vinegar, salsa, or any other products you like. After soaking, remove the coins and rinse them to see which ones clean the coins the best.

Make It an Experiment: Part of making this project an experiment is predicting which chemicals make the best cleaners. Also, you’ll have to determine the best amount of time to soak the coins. You can compare how well these chemicals work on different types of coins (like pennies, quarters, and nickels). Do you think the metal composition of the coin affects how well the cleaners work?

Make a Graphite Circuit

Graphite is a form of carbon that conducts electricity. You can draw a line of graphite using a pencil to make a simple circuit . Use a battery with both terminals on top (like a 9V). Turn the battery upside down on the paper and draw heavy pencil lines whether the terminal rest (don’t connect these lines!). Take an LED and bend the wires apart so they can rest separate on the paper. Rest each wire on a pencil dot. Complete the circuit by drawing lines to connect one terminal of the battery to one end of the LED light and the other end of the battery to the other LED wire.

Make It an Experiment: Explore whether the length or thickness of the line affects how brightly the LED glows. You can make a circuit using aluminum foil strips instead of graphite, too.

See Whether Food Color Affects Its Flavor

Examine the effect of color on perceived taste by coloring different drinks with food coloring and asking subjects to describe their flavor.

Make It an Experiment: Compare the flavor of colored and uncolored versions of the same drinks. Start with drinks that don’t have any color so subjects are less likely to guess the drink flavor in advance.

Test Whether Temperature Affects Maximum Balloon Size

Start with a package of party balloons (ideally all the same color and brand). Part of the fun of this science fair project is planning how you can test the effect of temperature on balloon size. Consider your options in terms of indoor versus outdoor weather and access to freezers and saunas. You need to blow up a balloon and measure its maximum size before it pops. Either get a friend to help with the measurement or fix a measuring tape to the wall and keep an eye on the numbers.

Make It an Experiment: You are well on your way to making an experiment if you make a prediction about whether temperature affects maximum balloon size and design a method to test the hypothesis. Can you propose an explanation for your results?

See If All Crayon Colors Melt at the Same Temperature

Crayons consist of wax, colorants, and sometimes fillers. See whether all crayons melt at the same temperature. You’ll need a bunch of different colors of crayons, a thermometer, and a way to melt them. Fortunately, wax melts at a lower temperature than water boils, so you can slowly heat water, watch for melting, and record the temperature. Another method is to place crayons (not-touching) on a sheet of wax paper on a cookie sheet, heat an oven to 350 ºF (or any temperature, really), and record which crayons melt first.

Make It an Experiment: Make predictions and answer questions. Do you get the same results with different brands of crayons? Do old crayons have the same melting point as new crayons? Watch for control variables , like the size of the crayons and whether you pre-heated the oven.

Make Lightning in Your Mouth

To make lightning in your mouth, crunch a Lifesaver Wint-O-Green or Pep-O-Mint candy in your mouth in front of a mirror in a dark room. Saliva can ruin the effect, so you might want to dry out your mouth with a paper towel first. The blue sparks that resemble lightning are due to an effect called triboluminescence . The sugar in the candy releases electrical energy when the crystals are compressed. The tiny charges attract nitrogen in the air, making miniature lightning bolts. Make It an Experiment: Get different types of hard candies and predict whether they will produce sparks in the dark. See if you can explain why some candies work better than others.

55 Super Fun Science Fair Projects For 6th Graders

Categories Activities & Ideas

Science is so fascinating, but it can sometimes be difficult to convince 11-year-olds that this is the case.

In order to capture their attention, you need to come up with something that will not only educate them, but also entertain them.

Below, we have listed 55 super fun science fair projects that 6th graders will love to try.

1. Carbon Sugar Snake

To start off this list, here’s an experiment that focuses on three heat-dependent chemical reactions. 

By lighting up some baking soda and sugar with a match, you can create a ‘snake’ made from carbon and sugar that continues to grow for up to 20 minutes!

2. Turn Milk into Plastic

With this experiment, you can teach your kids how to make plastic from lots of different materials, even including milk.

Once you’ve created the milky plastic, you can even melt and mold the organic casein polymer to make a new product.

3. Which Wheel Works Best?

This is a great way to teach kids about acceleration and velocity, and how the material of a wheel can affect the speed and resistance of a skateboard.

We don’t recommend trying this experiment if you’re not a very good skateboarder, however, as this could potentially result in injury.

4. Baking Soda-Powered Boat

By assembling a plastic bottle with some vinegar, baking soda, and a straw, you can create your very own mini speedboat.

The idea behind this experiment is very similar to making a baking soda volcano, as the chemical reaction creates pressure and movement.

5. Two-Stage Balloon Rocket

This is another experiment that kids can have lots of fun with, as well as learning all about how it works.

By attaching a balloon to the back of a straw, you can pump it up and release it across the room, allowing it to soar like a real life rocket.

6. Tiny Dancers (A Homopolar Motor)

By attaching a couple of wires and magnets to an AA battery, you can create your very own spinning ballerina!

You can even add some colorful crêpe paper to give your tiny dancer its very own tutu. Get creative, and learn all about how your dancer is spinning. 

7. Magic Spinning Pen

Magnets are some of the coolest tools ever, especially when you know how to use them to create fun tricks like these.

To create this magical spinning pen, you’ll need to use some small rods, a pen, a coin, and, of course, a couple of magnets.

8. Homemade Wigglebot

Did you know that you can make your very own robot using a plastic cup with googly eyes? This ‘robot’ can walk around all on its own!

This is another experiment that will teach your children how batteries work alongside motors.

9. Electromagnetic Train

Next up, we’ve got a science project that is so easy to set up, yet it will keep your kids entertained for hours.

An AAA battery attached to some magnets will become an electromagnetic train when placed at the entrance of a copper wire tunnel.

10. Holiday Card Circuits

Say goodbye to your run-of-the-mill handcrafted Christmas cards, and say hello to these impressive holiday card circuits.

By building a super simply circuit and taping it onto some cardboard, you can bring your festive designs to life… or, should we say, ‘to light ’? 

11. How to Make Fizzing Lemonade

Everybody loved carbonated drinks, but not everyone knows how they work. Where do the bubbles come from?!

Use this experiment to teach your kids (and yourself) how a chemical reaction using acid can turn your still drink into a bubbly one.

12. Solar-Powered Robot Bug

This solar-powered robot bug is also known as a ‘frightened grasshopper’. Why? Because it’s scared of the light!

Once you’ve assembled your robot bug, witness how it runs around when exposed to light, but comes to a standstill once it has been covered in shade.

13. Homemade Coffee Can Camera Obscura

Have your kids ever wondered how a camera works, or do they just accept it for what it is? If so, now is the time to teach them.

This camera is so easy to make from coffee cans and construction paper, and is so interesting and fun to use.

14. Heat Sensitive Color Changing Slime

From mood rings to heat-sensitive lip gloss, it is always impressive when an object can change color. This is all thanks to thermochromic pigment.

Add some thermochromic pigment to homemade slime made from white glue and liquid starch, and watch the magic happen.

15. DIY Crystal Landscapes

Have you ever seen anything as pretty and colorful as these vibrant crystal landscapes? You will find it surprising how easy they are to make.

You’re going to need to mix together some liquid bluing with water, salt, coloring, and ammonia to create these beautiful crystal creations.

16. Glow in the Dark Jello

Uh, hello? Glow in the dark Jello? Just when you thought that jello couldn’t get any more fun and yummy, this edible experiment pops up.

Boil some light-colored Jello with tonic water, let it cool in a mold, and then turn the lights out for the real fun to begin. 

17. How Do Roots Grow When the Direction of Gravity Changes?

We all know that gravity is what keeps our feet weighed to the ground, but what about plants? Does gravity affect the way they grow?

Make your own scientific container (made from a CD case), add some seeds, and switch up the directions every so often to test out this theory.

18. Seafloor Spreading Model

If you want to create a fun lesson plan to teach your students about the lithosphere, and how earthquakes occur, this is a great project to try out.

You will need to cut up a lot of paper for this project, so you can decide whether to do this beforehand, or to allow your students to fully make the project themselves.

19. The Science Behind Tsunamis

Tsunamis are terrifying natural occurrences, regardless of whether your hometown and country is at risk of them. 

Sometimes, learning about something can make it seem less scary. Teach your students about tsunamis using this experiment.

20. How Acidic Waters Make Rocks Disappear

It seems impossible to imagine that rocks can become worn down by water over time. With this project, you can work out how it happens, and why.

This is a great way to teach students about the effects of acidic water, and how stone can gradually become worn down and dissolved. 

21. Ice Cube vs. Wire

How could it be possible that one thin piece of wire could cleanly slice through an ice cube while leaving the rest of it intact?

Use a piece of wire and an ice cube to test the strange physics of water. To increase the fun, ask your students to guess how long it will take for the wire to split the cube.

22. DIY Heart Pump

Our bodies are fascinating vessels, and it can be so interesting to learn exactly what is going on inside ourselves.

This DIY heart pump may be a little fiddly to piece together, but once complete, you can show your students what is really going on inside their chests.

23. Engineering a Bridge

Engineering is a super fun and handy skill to have, whether it is something you want to make a career out of, or you’re just a crafty kind of person.

Use this sheet to ask your students how many popsicle sticks they think will need to create a sturdy bridge. Then, put their ideas to the test.

24. Earthquake Science Project

As we said earlier, sometimes knowing more about something (e.g., an earthquake) can make it seem a little less scary. 

This project involves creating sturdy structures, and then using books as a foundation to represent the earth’s plates. See how long your structures will stay standing, and work out how to improve them.

25. Magic Cloud in a Bottle

When we were kids, we thought clouds had the same texture as cotton candy, or the inside of a pillow. Nowadays, we know differently… but, do your students?

Teach them what a cloud really is by using rubbing alcohol and a pump to recreate what it really is, but in a smaller form.

26. Pop Rocks and Soda Science Experiment

Popping candy is so fun to eat, but do you know how it works? Why does it start popping when it goes into your mouth? (More on that later.)

For now, here is a fun variation on the ‘coke and Mentos’ experiment. Add some Pop Rocks into a bottle of soda, and see what happens…

27. Biodomes Engineering Design Project

By getting your students to design their very own biodome, they can learn more about how an ecosystem works.

You’re going to need some soil, seeds, sand, rocks, and even some creepy crawlies. Add them all into a plastic bottle, and take notes of what occurs inside.

28. Displacement and Buoyancy in Metal Boats

Archimedes’s principle, or the law of buoyancy, explains why some objects sink in water, while others don’t.

Use some foil and a bowl of water to test how well foil will float, depending on its size and shape. 

29. The Science Behind Edible Glass

Have you ever eaten glass? Normally we wouldn’t recommend it, but this edible glass is super tasty, and pretty easy to make.

Like real glass is formed through melted grains of sand, this glass is made from grains of sugar. Melt it on a baking sheet, allow it to cool, and then get eating (or smashing).

30. Cleaning Coins Experiment

When you begin to think about how many people have held the coins in your purse at some point, it can make your skin crawl a little. Coins are super dirty.

Try this experiment to see what material can clean coins the best, from apple juice to catsup. You’ll be surprised at how shiny your cents will be afterward!

31. Red Cabbage pH Indicator

Most people will remember learning about pH levels in school, and how much fun it was, seeing all the colors of the rainbow.

Blend up some red cabbage with water, and mix with everyday items – such as lemon juice and soda – to test their pH levels based on which color the liquid becomes.

32. Skittles Science Fair Project

Many of you may have seen this experiment through social media, with many people testing it out with their children at home.

This colorful project involves placing Skittles on a plate, and adding a couple of drops of water. Watch and see how the colors streak across each other.

33. Tooth Decay Egg Experiment

We all know that sugar is bad for our teeth, but how can you test that notion in a class of 6th graders? Well, by using some eggs!

Place hard-boiled eggs in separate containers filled with soda, energy drinks, orange juice, and milk, and wait to see how the eggs react to each liquid.

34. Science of Candy: Lightning in Your Mouth

Did you know that LifeSaver candy can glow in the dark? Yes , really! This is a great experiment to teach kids how friction can cause electricity, even in your mouth.

Go into a dark room, and chew on some wintergreen-flavored LifeSavers with your mouth open. Everyone around you will be able to see the lightning going off around your teeth.

35. Why Does Popping Candy Pop?

As we promised, here is an experiment that will teach children why popping candy does what it does!

There are tiny pockets of gas inside popping candy, which are released when exposed to liquid. Test this out by adding the candy to different kinds of liquids, from water to oil.

36. Which Fruits Rot the Fastest?

This is a pretty gross experiment, but it is still a fascinating one that the children are going to love. For this project, you will need to work with some rotting fruit.

Place different fruits in separate bowls, and observe how they decompose over the course of 14 days. Take note of what happens as they rot.

37. What Light or Heat Conditions are Favorable to Insects?

Have you ever been on your phone in a dark room, and a moth landed on the screen? Insects seem to be attracted to light… or, are they attracted to the heat of your phone?

Use this experiment to find out what conditions attract insects. You may want to avoid this one if you don’t like bugs, though.

38. Paper Towel Experiment

Paper towels are one of the world’s most underrated inventions, in our opinion. It really is fascinating how they can absorb so much liquid before breaking.

Is it really worth spending more money on a more expensive brand of paper towel? Test the theory by using different kinds of paper towels to clean up water, and see which works best.

39. Mini Marshmallow Launcher

This experiment can get a little messy, especially when kids are involved, so be warned before trying it…

Basically, this experiment is all about elasticity. You create a launcher using a balloon and a pool noodle, and use it to launch mini marshmallows around the room!

40. A Simple Ant Experiment

This is another messy experiment that will teach children more about creepy crawlies, and what they like to eat.

Find some ants, and use different kinds of food to lure them in. Take notes of which kind of food ants prefer to eat, and which ones they don’t like.

41. How to Make a Teleidoscope

Kaleidoscopes are truly magical contraptions, no matter what age you are. Did you know how easy it is to make your own at home?

This guide will teach you how to make your own teleidoscope ( a kaleidoscope without an end). All you need is some reflective sheets, colored paper, and a cardboard tube.

42. St Patrick’s Day Fizzing Pot Experiment

This experiment is kind of like those baking soda volcano experiments that we all made in school, but with an Irish twist.

Grab some small, black plastic pots, and add some baking soda, vinegar, and green food coloring inside. Give it a stir, and see what happens.

43. Seed Germinator

Is there anything more interesting than watching life form before your very eyes? By germinating some seeds, you can do this in your own classroom.

Use some fast germinating seeds, and place them in some soil on top of a coffee filter or paper towel inside a container. Watch them grow with each passing day.

44. The Biology of Yogurt

Yogurt is so tasty, but it can make some people feel a little weird when they think about what it is made out of. Live microorganisms have never tasted so good!

Providing that you have an oven on hand, along with some cooking utensils, you can show your children how to make homemade yogurt.

45. Pouring Water Down a String

String is super absorbent, which is what makes this experiment so fun and intriguing. All you’ll need is three materials to carry it out!

We recommend adding some food coloring to the water so that you can see the colors travelling through the string as it spreads.

46. How to Make a Modern Art Steady Hand Game

Anyone who has ever played a game of Operation will immediately know how this game works. Turns out, you can easily make this at home.

You will need some batteries, clip leads, copper wire, and more to create this fun game. Once the circuit is complete and the box has been built, you can start playing!

47. Rapid Color Changing Chemistry

We’re back with another magical color changing experiment! This time, you will be using vitamin C, iodine, liquid starch, and hydrogen peroxide to create a clock chemical reaction.

As you mix and pour each liquid into each other, you will notice that the color of the liquid will vastly change. 

48. Engineer a Cell Phone Stand

Science experiments are cool, but they’re even better when you get to create something that you can use more than once.

Use some popsicle sticks, paper clips, and rubber bands to make your very own cell phone stand. This will teach children how to make use of everyday objects, and recycle them.

49. Law of Inertia Experiment using a Fidget Spinner

The law of inertia states that if a person or object is moving at a constant speed in a straight line, they will continue to move until a force stops them. This force is, more often than not, friction.

You can test this law by using a light-up fidget spinner. Spin the fidget spinner without its lights on, and try again with them on. Time each try, and make note of your observations.

50. Catapults and Trajectory

This is probably the easiest experiment to attempt in this entire list. All you need are some wooden planks of different lengths and weights, and some random objects.

Try catapulting the same objects from different sized planks by stamping on them, and make note of how the size of the plank affects the trajectory of the object.

51. Lung Science Experiment

If you liked the DIY heart experiment, you will also like this one. Instead of making a replica of the human heart, this project recreates the human lungs.

You will need balloons, straws, and a clear plastic bottle for this experiment. One balloon will represent a healthy lung, while the second balloon (with another balloon inside) will represent a smoker’s lung.

52. Dissecting an Owl Pellet

Did you know that owls will regurgitate things that they have eaten that they cannot digest? These bones and pieces of gristle are spat out as a pellet.

Dissecting an owl pellet can be really interesting or really gross, depending on what kind of person you are. Either way, prepare to find some skeletons in your pellets!

53. Potato Battery

While we usually don’t recommend eating batteries, this is one battery that is actually pretty delicious. Yes, you can use a potato as a battery.

With some heavy copper wire, alligator clips, and some nails, you can connect a raw potato to a fully-functioning LED clock… and it will work !

54. Ice Cream in a Bag

This is probably the tastiest experiment in this list, and it is also one of the easiest. This is how you can make instant ice cream in a bag.

Fill a ziplock bag with ice and salt, and fill another bag with all the ingredients you need to make ice cream. Place the second bag in the first, and mush it around until it becomes ice cream!

55. Sugar Cookie Solar System

Finally, we have an entry that is not so much an experiment, but more of an activity that will help kids to learn about the planets in our solar system.

After all, what motivates children more than desserts?

Final Thoughts

Whether you have a child who’s interested in engineering, or they’re fascinating by stuff that changes color, there is something in this list for everyone. Each entry is as entertaining as it is educational!

We hope you found this guide helpful. Ready to learn more? Take a look at these 7th grade science experiment ideas .

Write a Clear Hypothesis

Before starting your experiment, it’s crucial to develop a clear hypothesis. This is a statement that predicts the outcome of your experiment based on your understanding of the topic. A good hypothesis should be specific, testable, and based on prior research.

For example, if your project is about plant growth, your hypothesis could be: “Increasing the amount of sunlight will result in faster plant growth.”

Follow the Scientific Method

The scientific method is a systematic approach used by scientists to conduct experiments. It consists of several steps, including making observations, asking a question, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions.

By following this method, you can ensure that your experiment is well-structured and that you are able to make accurate conclusions based on your findings.

Repeat Trials for Reliable Data

One important aspect of conducting a scientific experiment is the need to repeat trials. By repeating your experiment multiple times, you can ensure that your results are reliable and not due to chance. This will also allow you to identify any inconsistencies or outliers in your data.

For example, if you are testing the effect of different fertilizers on plant growth, you should conduct the experiment with multiple plants and repeat the process several times to ensure consistent results.

Remember, conducting your experiment in a systematic and organized manner is key to a successful science fair project. By writing a clear hypothesis, following the scientific method, and repeating trials for reliable data, you can ensure that your project is well-executed and yields accurate results.

Analyzing Data and Presenting Results

Organize quantitative data clearly.

When analyzing data for a science fair project, it is crucial to organize the quantitative data in a clear and organized manner. This allows others to easily understand the information you are presenting and draw meaningful conclusions from it.

One way to achieve this is by using tables or spreadsheets to arrange the data. By labeling each column and row appropriately, you can make it easier for the reader to interpret the data. Additionally, consider using headings or subheadings to categorize the data into different groups or variables.

This will help make your findings more accessible and coherent.

Highlight Key Findings in Charts/Graphs

Another effective way to present your results is by creating charts or graphs that highlight the key findings of your experiment. Visual representations of data can often be more impactful and easier to understand than long paragraphs of text.

Bar graphs, line graphs, and pie charts are just a few examples of visual tools you can use to showcase your data. Be sure to choose the appropriate type of chart or graph that best represents your data and effectively communicates your findings.

Consider using different colors or patterns to differentiate between different variables or data points, making it easier for the reader to interpret the information.

Prepare an Eye-catching Display Board

Science Struck

A Really Interesting List of 6th Grade Science Experiments

Science experiments help kids understand certain basics and fundamentals of science in a fun way. Experiments are set up according to their level and skills. In this ScienceStruck article, you shall find some topic ideas and experiments for 6th grade students.

Like it? Share it!

Reaching 6th grade is fun because then you become eligible to perform middle school experiments that may capture your interest a lot. Performing science experiments is not only interesting, but it also develops analytical skill that may prove useful in the future when working on research projects. Students are enthusiastic about performing science experiments because it gives them the opportunity to exhibit their analytical and creative skills.

Science Experiments for 6th Graders

You should go through the laboratory safety guidelines and the procedure for handling the laboratory equipment before starting any experiments to avoid any mishaps. In 6th grade, students are allowed to handle instruments and samples that are safe, and do not involve any risks. Handling fire or strong chemicals is usually not a part of 6th grade projects. Here are some fun science experiments for 6th graders.

The Egg Experiment

This is one of the most commonly used substance for 6th grade science experiments. With eggs students can learn rules and laws of science. They can perform a number of practicals, that can include observation of eggs sinking or floating on changing the density of the water, or the difference in composition of hard-boiled eggs and raw eggs.

Set up the experiment in different containers. The first containing plain water, the second containing sugar and the third containing salt. Now, dip the eggs in each container and record the results. Try to analyze the results with the help of your teacher. You can also find out the differences between hard-boiled eggs and raw eggs by allowing it to spin.

Evaporation of Water

In this science activity you will determine the rate of evaporation of water under different intensity of light. You will have to construct several boxes installed with electric bulbs having different wattage. The containers are simultaneously filled with water and the bulbs are lit. You also need a controlled experiment that will be devoid of bulb. You will notice that the rate of evaporation is highest in the container having maximum power of bulb. This happens because water changes to vapor form more quickly under intense temperature. Since the surrounding temperature of the bulb with highest power is more, so the rate of evaporation is also more.

Make a Periscope

A periscope can be used to see objects when you are in a concealed position. To make one, you will require two pipes, at least 10 inches long. The diameter of one pipe should be slightly larger than the other, so that one can slide over the other. You’ll need 2 elbow joints, each matching the diameter of either pipes. Also you’ll require 2 circular mirrors, along with some super glue.

To begin with, stick the mirrors in the elbow joints at a 45 degree angle. This is the precise angle that reflects the light is such a way that it lets you see the best view. Now, fix the appropriate pipe into the respective elbow joints. Finally, slide the larger pipe on to the smaller one, and your periscope is ready to use.

Inflate a Balloon by Itself

This is a fun experiment that teaches you how a chemical reaction can inflate a balloon. You’ll be needing a small balloon, a test tube, vinegar, funnel, and a teaspoon of baking soda.

Fill the test tube half way with vinegar. Then, stretch the balloon a bit, and use the funnel to pour the baking soda into it. Now, carefully stretch the opening of the balloon over the mouth of the test tube and ensure that the baking soda does not fall in the tube. Once you’ve ensured that the balloon snugly fits over the mouth of the test tube, lift the balloon and tap it, so that the baking soda falls into the vinegar.

When the baking soda falls into the vinegar, the solution turns into carbonic acid. This makes it unstable, and it releases carbon dioxide, which rises up and inflates the balloon.

Make it Rain

This simple experiment is a fantastic way to learn how the changes in temperature bring about rain. You’ll need a glass jar, some steaming hot water, a dish big enough to be placed over the jar, and some ice cubes.

Pour the boiling water into the jar, filling about a third of the space. Place the plate on top of the jar, and wait for a couple of minutes. Put the ice cubes on the plate, and observe what happens inside the jar. You’ll begin to see droplets of ‘rain’ sliding along the sides of the jar.
