Growing beans in a bag is an activity I remember doing when I was in school, so I thought it would be fun to do it with my son. He loved seeing the beans grow, and checked them daily to see if there were any changes!

This is such a great way for your kids to watch the process of how a plant grows. It’s something that we normally don’t get to see, since it usually happens while buried in soil.

All you need is a plastic bag, paper towel, beans, and this (optional) free printable, and you can grow beans in a bag too!

What kind of beans can I use?

Lima beans and pinto beans will grow the fastest, but any dried beans that you already have at home will work.

Jack and the Beanstalk

For toddlers and preschoolers, a fun activity would be to read the book Jack and the Beanstalk , and then to grow these “magic beans” in a bag. The kids will be excited to see the beanstalks shoot up!

How do you grow beans in a bag?

• dried beans
• paper towel
• free printable
• markers/crayons

Step 1: Soak your beans overnight. This step is optional, but it will make your beans grow faster.

Step 2: Color the free printable, then cut out the square in the middle.

Step 3: Slightly wet a paper towel so it’s damp (not soaked) and insert it in the plastic bag. Place the beans in the bag and seal it. Then, tape the bag to the back of the paper.

Step 4: Tape the paper to a window that gets a good amount of sunlight. And that’s it! Sit back, and watch your beans grow! The beans will normally start to sprout in 3-7 days.

The paper towel may get a little moldy over time. If so, gently remove it and replace it with a fresh, damp paper towel.

Once your beans have grown roots and a stem, you can plant them and continue to watch them grow. Check out this Easy Self Watering Milk Jug Planter .

How to Grow a Lima Bean in a Bag

Sprouting lima beans in a plastic bag creates an exciting experiment for young children. Lima beans can easily begin growing roots and shoots when supplied with the right growing conditions. Soaked paper towels create enough moisture to allow the beans to grow, while sunlight heats the plastic bag and generates humidity. Once the lima beans inside the plastic bag sprout, you can transplant them to a flower pot or grow them in your garden.

Soak the lima beans overnight in cold water to help start germination. You will only need to soak four or five beans to get at least two or three that will sprout. Place enough water in a bowl to cover the lima beans.

Video of the Day

Lay four or five sheets of paper towels on top of each other. Spread the soaked beans in single layer on the paper towels. Place another layer of four or five paper towels on top of the lima beans.

Fill a spray bottle with water. Spray the paper towels with a fine mist of water until they are thoroughly damp.

Slide the moistened paper towels, with the beans between them, into a gallon-size plastic zippered bag.

Seal the zippered bag tight. Leave some air inside the bag to aid in the germination process. Place the sealed bag on a windowsill to allow the beans to stay warm and receive plenty of sunlight.

Check on the beans in the bag every day and spray more water on the paper towels if they appear dry. Green shoots should begin sprouting from the roots in a few days' time.

Fill a flowerpot with soil. Use your fingers to create a 1-inch hole for each sprouted lima bean. Keep the holes at least 3 or 4 inches apart. You may need to use more than one flowerpot.

Drop one sprout into each hole and cover with soil. Water enough to moisten the soil and place the flowerpot in a sunny location.

Growing Beans in the Classroom

Nothing like setting up an experiment in the classroom and it not turning out exactly how you expected, right? Well, I’m here to share all my tips and tricks for growing beans in the classroom so your experiments are a success!

• dried beans (pole, bush, or lima beans)
• paper towels
• spray bottle of water
• clear glass jar or small clear plastic cup

My #1 Tip for Success

Before I go any further, I want to tell you the one thing I feel makes or breaks this experiment. It’s what will get you tall, lovely sprouts like the picture above in only ten days:

Soak the Beans in Water Overnight!

I can’t stress enough that you should soak the beans in water overnight beforehand. I’ve tried the experiment with and without soaking the beans. Soaking the beans boosts the germination process and you see roots in a day or two. Within ten days, the bean sprouts have a tall stem with leaves growing out of the top of the jar. When I’ve not presoaked the beans, it took five or six days for the first root to begin to emerge. Even then, the entire germination process seemed to go a lot slower.

Now that you’ve soaked your beans, let’s start the experiment!

• Fill the container about halfway with paper towels.
• Place several beans on the outside of the paper towels in the container so you can watch them grow.
• Spray the paper towels with water to dampen them.
• Place the container near a window or on a window ledge.
• Observe and watch the beans grow over the following days and weeks!

Can the Seeds Grow Without Soil?

We teach students that plants need water, air, sunlight and soil to grow. Some students may wonder how these seeds will grow without soil. It might be helpful to point out that you can germinate seeds, or help them start to grow, without soil. Why? It’s because the food the seed needs to start growing is inside the seed. The seed provides food for a short time and then you must plant the seedling in soil for it to continue to grow.

Experiment Variations

This experiment helps students learn the basic needs of seeds and plants. What happens if they don’t get what they need?

Prepare a few extra jars with beans and alter some of their growing conditions. Observe what happens.

• No water : Don’t soak the beans in water overnight or wet the paper towels in the container.
• No air : Use a sandwich bag for this one. Use a straw to suck as much air from the bag as possible before zipping it shut.
• No sunlight : Place the jars away from windows or even in a dark space like a cabinet.
• Not enough space : Place seeds in a group touching each other.
• No soil : Seeds will germinate without soil, but will they keep growing and produce fruit (beans) if left in the container with no soil? This will take a lot longer to observe. Another option is to plant the beans in sand. Give them water and sunlight, and observe what happens.

Growing Beans FAQs

What beans did you use? I used pole and lima beans. I’ve successfully germinated both kinds.

Do I need beans from a seed packet or can I used dried beans from the grocery store? While you may certainly use a purchased seed packet of beans, I’ve always had success germinating and sprouting dried beans I’ve brought at the grocery store. I recommend soaking and germinating a couple of dried beans at home to make sure your dried beans will work before doing it with your students.

How long will it take to see anything? One or two days if you soak the beans overnight, five or six days if you don’t soak them. I soaked my beans overnight and put them in a jar and baggie. The very next day I already saw the root coming out of most of the beans.

Can I do this experiment anytime of year? I think so! I live in the Midwest and germinated these seeds towards the end of January! Even though it was cold outside and the windows themselves felt cold, there was enough sunlight and warmth to begin germination. If you want to keep the plants alive or transfer them into a garden, you will need to begin germination closer to actual planting time.

What if the paper towels get dry? Use a spray bottle of water to moisten the paper towels if you feel they are too dry.

Can I germinate beans in a sandwich bag? Absolutely! Just place a damp paper towel and several beans in a zip-top sandwich bag and seal it. Then tape or place the bag on or near a window and watch them grow!

Students learn so much about plants by growing beans in the classroom. It’s really fun to watch the little beans grow so quickly. Sometimes there’s a huge difference from day to day. I hope these tricks and tips help you and your students become expert germinators!

I really enjoy to see the plant growing.

hi this is cool info

Hey there! I am soaking my Lima beans to grow in our classroom and I noticed they are wrinkling and some of them are splitting. Is this normal? Thanks so much for your info! We’re excited to try it!

That’s a great question! The wrinkles are completely normal. As for splitting, when the inside of the bean rehydrates quicker than the outside, the bean will split. It happens sometimes. You can have students examine the split beans to see what’s inside the seed. Good luck and I hope your students enjoy growing their beans!

Hi, I’m a PreK teacher and have found the past several years, that the beans get moldy in the children’s ziplock bags. How can I avoid the mold?

That’s a great question! I might try doing it with glass jars instead of baggies. I’ve never had an issue with mold when growing them in glass jars like I shared in the blog post. I also leave the lid off to allow air circulation.

If you need to use bags, you might try leaving the top open or making a few holes near the top of the zipped bag. Another idea is to only leave the beans in the bags for just a few days and plant them as soon as you can.

I hope these ideas help! Good luck!

Hi Cara! Two easy tricks are 1) spritz rather than soak the towels in water 2) staple a horizontal row of staples about two inches down the bag and place lima beans along the staples before sealing. Veteran teacher tip—best of luck!

They need to wash their hands thoroughly before “planting”.

When do you put the bean in soil?

Hi! I plant them as soon they look like the one pictured with roots, stem, and a few leaves. They shoot up very quickly, so it’s not long before they’re ready to be planted.

Now that my granddaughter brought home her bean,what do we do with? A single plant. Does it need something to climb? Or will it get bushy? We weren’t given any follow up info sadly. HELP

That’s a great question! If you can find out what kind of bean it is, that would be helpful. Some beans are runners and need to be staked or have something to climb, while others don’t. Other than that, just plant it in soil and watch it grow!

I tried this experiment with my class and we have a few moldy plants. We wet the paper towel again every day. Does this mean the plants are dead?

Hi! If you do this experiment again, I suggest just lightly spraying the paper towel with water whenever it feels dry instead of watering them each day. If you soak the beans beforehand, they already have a good bit of water inside them. I also take the top off of the jar after they begin sprouting so air can circulate. Hopefully, doing those two things will stop the mold problem. Good luck!

Suggestions on the bean plant being towering over the cup? Do I need to get dowel rods? I feel bad because my kids are taking them home and I wanted them to be successful .

That’s a great question! Even though the plants stick up over the cup, they’re usually sturdy enough to send home. If you want to give them extra support, you might stick a straw in the cup and gently tie the plant to it. I hope your students have a great experience sprouting seeds!

hi im in 5th grade and when i grow up i will show my children this and might do this for their birthdays

If the seeds have mold, does that mean they are dead? Or can I salvage them?

Additionally, how do I safely transfer them to plant so that students can take home? Do I need a certain type of soil? A pot?

Hi, Alex! Those are great questions. First, if your seeds have mold, I would throw them out and start over. When you try again, here are my tips to avoid mold:

1. Just lightly spray the paper towel with water whenever it feels dry. If you soak the beans beforehand, they already have a good bit of water inside them so they don’t need lots of water. Too much water in the jar or bag will allow mold to grow.

2. Take the top off of the jar after they begin sprouting so air can circulate. If you use zip-top bags, open the bags after the beans sprout.

3. Avoid direct sunlight for long periods. Too much heat inside the jar or bag will cause mold to grow. The beans will still sprout near a window with indirect sunlight.

If you want to plant them for students to take home, use potting soil (not garden soil) and any small plastic container like yogurt cups, bottom half of a water bottle, or other small plastic cups you might have in your recycling bin.

I hope those ideas help! Good luck!

Will pinto beans grow?

Hi, Maria! I’m so sorry I’m just seeing your question! I’m not getting emails when someone posts a comment like I usually do, and I’m not sure why. I haven’t tried pinto beans because I’ve read they don’t sprout as reliably as other beans. It might be interesting for kids to try to grow pinto beans along with other types of beans to see which ones sprout the best.

I have jars without lids. Do I need lids to begin this process?

That’s a great question! You don’t need lids to begin the process. You might put plastic wrap or aluminum foil over the jar for the first few days. I think it’d be interesting for kids to observe a covered jar and one that isn’t. Then, they can see if covering the jar affects growth.

This activity is perfect for children who love to explore what is in store for them in the real world. Thank you so much for sharing this.

Growing beans in a bag

An experiment to explore germination.

To grow beans in a bag is an experiment that helps children understand germination. It's easy to do, and the children will enjoy it.

Instructions

1. Place several damp, folded paper towels into a zip lock bag. Insert five staples about halfway up the bag. This will keep the beans in the right place so that there's room to watch the roots grow.

3. Place a few beans into the bag.

4. Tape the bag onto a wall or window. Add water as needed to keep the paper towel damp.

5. Watch what happens! About three days after planting the first roots appear...

A few days later: the stems start to push upward.

After ten days the leaves begin to peek out of the seed coat.

Two weeks: the first true leaves appear while the stem continues to grow and grow!

How tall will they get? (Larry is sure they'll touch the ceiling!)

Lima Beans in a Bag: Exciting Gardening Hack

Ever since I was a child, I’ve always been fascinated by lima beans. Their unique taste and versatility in various dishes make them one of my favorite legumes. As an avid gardener, I’ve grown numerous vegetables and herbs over the years, but I wanted to try something different this time. That’s when I came across the idea of growing lima beans in a bag.

Not only is it a fun and educational project, but it also allows you to witness the entire germination process up close. So, I decided to give it a shot and document my journey in hopes that it would inspire others to try this simple yet rewarding gardening experiment.

My Journey to Growing Lima Beans in a Bag

Gathering Supplies

Before embarking on this lima bean adventure, it’s essential to gather all the necessary supplies. Here’s what you’ll need:

• Lima beans : You can find these in any gardening store or online. Make sure they are untreated seeds, as treated seeds may contain chemicals that hinder germination.
• Plastic bags : Ziplock bags work best for this project, as they are durable and easy to seal. You can use quart-sized or gallon-sized bags, depending on how many beans you want to grow.
• Paper towels : These will be used to create a moist environment for the beans to germinate.
• Water : To dampen the paper towels and maintain humidity inside the bag.
• Permanent marker: For labeling the bags with the date and type of seed, so you can keep track of their progress.
• A sunny windowsill or warm, well-lit area : This will provide the necessary warmth and light for the beans to germinate and grow.

Once you have gathered all your supplies, you’re ready to embark on the exciting journey of growing lima beans in a bag!

Preparing the Lima Beans

Before you start setting up the bag environment, it’s essential to prepare your lima beans to ensure successful germination. Follow these simple steps:

• Inspect the beans : Look for any damaged or discolored seeds and discard them, as they may not sprout properly.
• Rinse the beans : Place the lima beans in a colander or sieve and rinse them thoroughly under running water to remove any dirt or debris.
• Soak the beans : Fill a bowl with enough water to fully submerge the lima beans and let them soak overnight, or for at least 8-12 hours. This process softens the seed coat and kick-starts the germination process.

After soaking the beans, it’s time to set up the bag environment for their growth.

Setting Up the Bag Environment

Creating the perfect environment inside the plastic bag is crucial for the successful germination and growth of your lima beans. Here’s how to do it:

• Prepare the paper towels : Start by dampening two or three paper towels with water. Make sure they are moist but not dripping wet, as excess water can cause the beans to rot.
• Line the plastic bag : Place the damp paper towels flat at the bottom of the plastic bag. This will provide a moist environment for the beans to germinate and grow.
• Position the lima beans : Remove the soaked beans from the bowl and gently pat them dry with a clean towel. Then, evenly space them out on top of the damp paper towels inside the bag. Make sure they aren’t touching each other to prevent overcrowding as they sprout.
• Seal the bag : Once the beans are in place, carefully seal the plastic bag, ensuring there’s some air trapped inside. This will create a humid environment that promotes germination.
• Label the bag : Use a permanent marker to write the date and type of seed on the outside of the bag. This will help you keep track of the progress and compare the growth rate with any future experiments.
• Find a suitable location : Place the sealed bag in a warm, well-lit area, such as a sunny windowsill or under grow lights. The ideal temperature for lima bean germination is between 65-75°F (18-24°C).

Monitoring the Growth Process

As your lima beans embark on their journey of growth, it’s essential to keep a close eye on their progress and make adjustments as needed. Here’s what you should do:

Check on the beans daily

Observe the beans every day to ensure they are moist and healthy. You should start seeing sprouts within 3-10 days, depending on the temperature and bean variety.

Maintain moisture levels

If you notice that the paper towels have begun to dry out, carefully add a small amount of water to re-moisten them. Be cautious not to overwater, as this can cause the beans to rot.

Monitor for mold or rot

Keep an eye out for any signs of mold or rotting beans. If you spot any issues, remove the affected beans immediately to prevent the problem from spreading to the other beans.

Track growth progress

As the beans begin to sprout and grow, you’ll see the roots extending into the paper towels and the shoots emerging from the seeds. It’s a good idea to take pictures or jot down the growth progress in a journal, so you can document the entire process.

Transplanting the Sprouted Beans

Once your lima beans have sprouted and developed a healthy root system, it’s time to transplant them to a more suitable growing medium. Follow these steps to give your sprouted beans the best chance of thriving:

Choose the right time

The ideal time for transplanting is when the sprouts are about 1-2 inches long, with well-developed roots and a few leaves. This usually occurs within 2-3 weeks after germination.

Prepare the new growing medium

You can either transplant the sprouted beans into pots filled with a high-quality potting mix or directly into a garden bed, depending on your preference and available space. If planting in pots, make sure they have drainage holes to prevent waterlogged conditions.

Carefully remove the sprouts

Gently separate the sprouted beans from the paper towels, taking care not to damage the delicate roots. Use a pair of tweezers or your fingers to carefully disentangle the roots if they have grown into the paper towels.

Plant the sprouts

Dig a small hole in the potting mix or garden bed, deep enough to accommodate the root system. Place the sprouted bean in the hole, ensuring that the roots are fully covered, and gently pat the soil around it to secure it in place.

Water the transplanted beans

After transplanting, give the beans a thorough watering to help them settle into their new environment. Be careful not to overwater, as this can lead to root rot.

Caring for the Growing Lima Beans

Now that your lima beans have been transplanted, it’s crucial to provide them with proper care to ensure a healthy and bountiful harvest. Here are some essential care tips:

Keep the soil consistently moist but not waterlogged. Lima beans generally require about 1 inch of water per week, either from rainfall or supplemental watering. Make sure the soil drains well to prevent root rot.

Fertilizing

Although lima beans can fix nitrogen from the atmosphere, they may still benefit from additional nutrients. Apply a balanced, slow-release fertilizer at planting time, or use a liquid fertilizer according to the package instructions every 4-6 weeks.

Providing support

As your lima beans grow taller, they may need support to prevent them from toppling over. Install stakes, cages, or trellises to help support the plants and make harvesting easier.

Pest control

Keep an eye out for common pests like aphids, spider mites, and bean beetles. Use organic or chemical insecticides as needed, following the manufacturer’s instructions. You can also introduce beneficial insects like ladybugs to help control pests naturally.

Disease prevention

Practice crop rotation and avoid planting lima beans in the same location year after year to reduce the risk of soil-borne diseases. Remove any diseased plants promptly to prevent the spread of infection.

Harvesting and Enjoying Lima Beans

After several weeks of growth and care, your lima beans will be ready for harvest. Here’s how to know when it’s time to pick and enjoy your homegrown legumes:

Check for ripeness

Lima beans are typically ready for harvest when the pods are plump and firm, with a bright green color. The beans inside should be fully formed but not bulging out of the pod. This usually occurs 60-90 days after planting, depending on the variety.

Harvest carefully

Gently pick the pods from the plants, being careful not to damage the vines or disturb any unripe pods still growing. It’s best to harvest in the morning when the pods are crisp and fresh.

Enjoy your lima beans

You can eat your freshly harvested lima beans either raw or cooked. To prepare them, remove the beans from the pods and rinse them well. You can then steam, boil, or sauté them, or add them to soups and stews. Lima beans also freeze well, so you can store your harvest for later use.

Growing lima beans in a bag has been an exciting and rewarding journey. From the initial germination process to transplanting the sprouted beans and caring for the growing plants, each step has been a fascinating learning experience.

I hope that my journey has inspired you to try this fun and educational project, whether you’re a seasoned gardener or a curious newcomer. With patience, care, and a little bit of luck, you too can enjoy the satisfaction of harvesting your very own homegrown lima beans!

Sprouting a Seed: Bag Topper Printable

Here’s a printable bag topper for kids’ seed sprouting projects. Sprouting a lima bean (or any seed) in a zip top bag is a simple science project for kids. This seed sprouting activity will go great during your Plants & Seeds Theme .

Having already made several treat bag toppers for different holidays, one day I thought about making a bag topper for sprouting a seed in a zip top bag.

For this activity, you will need:

• sandwich size zip top bags
• lima beans (or other seeds of your choice)
• either paper towels or cotton balls
• cups or bowls
• printable bag topper
• tape or stapler
• water dropper (optional)

Here’s what to do:

Give each child in your group a zip top bag (sandwich size) and a lima bean. You can use either paper towels or cotton balls to place in the bag. If you use a paper towel, have kids fold it, dip it in a cup or bowl of water and squeeze it out a little so it won’t be too wet. Or, have them dip a few cotton balls in the water.

Place the damp, folded paper towel or cotton balls in the ziplock bag. Drop a lima bean or other seed in the bag, making sure it touches the damp towel or cotton. Cut out and fold the bag topper, write the child’s name and date, and either staple or tape the topper to the bag.

Hang these in the window for a few days and watch the seed sprout!

What might go wrong & what to do:

Because the bag is moist and sealed up, the seed can mold. It might help to leave part of the bag’s top open.

Our seeds were very slow to begin sprouting. In the photo above, you can see that it’s just beginning to sprout after about a week. To give them a head start, you can soak the beans or seeds the night before your project.

It’s a good idea to make a few extra bags (or have the kids make a few extra) just in case someone’s seed doesn’t sprout.

Make Your Lima Bean Science Experiment Fabulous With These Gardening Tips

Some time during the year, school-aged kids may have to try growing a bean in a jar. This classic experiment is great fun for the kids and there are plenty of opportunities to teach your students about plants and to introduce the scientific method.

In the experiment, keep a control group of beans while changing conditions for other groups, and have students keep science journals to track the beans’ progress. To add some more fun, read growing-related stories like Jack and the Beanstalk!

Lima beans are usually robust sprouts, but if you want to make your experiment extra fabulous, try these tips.

Tip #1. Use glass bottles and cotton balls to help your students with observation and prevent bean rot

Most versions of this experiment instruct students to dampen two paper towels, insert the lima bean between them, and slide everything into a plastic bag. While this keeps the bean moist, it limits what students can see. There’s also the potential to overwater the paper towels, which will cause the beans to rot rather than grow.

As a less risky and more aesthetic alternative, use cotton balls and a mason jar. Dampen the cotton balls and place them at the bottom of the jar, and slide the bean against one side of the jar just under the top layer of cotton balls. Your students will be able to see the bean’s roots and leaves as it grows, and the cotton balls will keep the bean moist.

As an added bonus, it’s easier to re-dampen cotton balls in a widemouth glass jar than it is in a plastic baggie. Get a mister and let students spray the cotton balls to wet them.

Tip #2. If you only have plastic baggies, staple the bottom fourth of the bag for better drainage

Sprouts don’t like sitting in water. In the classic bean experiment, beans tend to sink to the bottom of a plastic bag, where they can end up too moist. It’s easy to overwater a bean and have it grow mold or rot instead of sprouting!

If you’re using baggies, use a stapler to line up several staples horizontally along the bottom fourth of the bag. Let the bean sit on top of the staples. If your students accidentally overwater their beans, the extra water will collect at the bottom of the bag, but the bean will stay properly moist.

Tip #3. Use colored cellophane or film to alter the light in the bottle

Part of the fun of the experiment is to see what happens when you alter the bean’s growing environment. The most common conditions to alter are light and liquid type (like what happens if you add juice? milk? soda?), but if you’re feeling adventurous, try changing the color of the light in the jar to see what happens to the bean. Plants rely on red and blue frequencies to photosynthesize, so using film of this color will allow red and blue rays to get through, and your plant will grow happily. However, using a green or brown film will block photosynthesis and prevent your plant from growing well.  Read our article about how colored bottles affect growth here. 

Try putting one plant in the dark, wrapping a few jars in green or brown film, and wrapping a few jars in red or blue film. All of the beans may sprout, but after a week the ones in the clear, red, or blue jars should be stronger than the ones in the green and brown jars, and all should be stronger than the plant grown in the dark. Talk to your students about how plants need light of a specific type to grow and use prisms or rainbows for demonstratives

Tip #4. Set up your bottles on a windowsill to make a window garden

Many teachers tape plastic bags to the window. That works, but it can look messy. If you’re using jars and you have a windowsill, set all your jars along the sill instead.

For a fun class project, you can have students decorate their jars before you fill them. Provide markers or stickers so each student can personalize their jar. Just make sure that any added decoration won’t prevent light from entering the jar. For more tips,   read our article on how to select the perfect spot for a plant to grow.

Tip #5. Have an adult growing experiment

At Urban Leaf, we think everyone should have fun with plants! (In fact, we love to experiment with our own plants!  Check out how we tested the best growing environment for our herbs. ) Our herb bottle gardens require even less maintenance than the classic lima bean experiment and yield even tastier results. (They’re also really pretty!) We’ve incorporated the principles of light and water above into our garden designs, so that growing plants is easy and hassle-free.

My son is doing an experiment for school to see if the phases of the moon affect plant growth. He planted a lima bean on 02/01/22, in a small glass jar with potting soil and put it in our window seal inside. but 3 days later we had freezing temperatures in the 20’s. We forgot to take the plant out of the window seal, but it was inside the entire time. Will this damage the seedling? It has been 11 days since planting and no growth can be seen.

Lima Bean Science Projects

Science Fair Ideas for 5th Grade

Growing a plant from seed is a measurable science project, and lima beans are an efficient seed choice. Lima beans sprout easily and grow quickly, making them a popular choice for science experiments with time constraints. There are lima bean science projects that will help students learn about plant growth, soil and climate.

Planted or Wrapped?

A simple lima bean science project involves asking how beans will grow more effectively: planted in soil or wrapped in a damp paper towel? Students can each plant two lima beans in cups of soil. They can place two more lima beans on a damp paper towel, which they will wrap around the beans and seal in a plastic bag. Place both types of planted beans in a sunny spot, and water as needed. Make a chart to track the progress of each and see which one grows fastest.

Soaked or Dry?

Some seeds germinate better when they are soaked first. Do lima beans grow better when they are placed directly into the soil, or when they are soaked first? Soak lima beans overnight. The next day, plant the soaked lima beans. Then plant dry beans. Chart which beans grow faster. Discuss whether the results would be true for all beans and seeds.

Do Earthworms Help Lima Beans Grow?

Plant lima beans in two flower pots. Place soil and beans in one pot. Put earthworms in the other pot, along with the soil and beans. Chart which beans grow faster. Discuss why it happens and what effect earthworms have on soil and seeds.

Light, Water and Soil

Plants supposedly need light, water and soil to grow. Conduct an experiment to find out if that's true. Put two lima beans in a cup and give it water and light, but no soil. Plant two lima beans in a cup of soil and give it water, but place it in a dark area with no light. Plant two lima beans in a cup of soil and give it light, but no water. And plant two lima beans in a cup with soil, and give it light and water. Chart your findings. Can a bean grow without water? Without soil? Without light? Which beans do best?

• Lima Bean Experiment

7 comments:

Hi, I found your blog through this post a few weeks ago. Im a first year, first grade teacher. I'm currently doing this experiment, and I'm curious about when you put the plants in soil. Our plants are reaching this point, any help is appreciated! Thank you!

I planted the lima beans in soil when they reached the stage that you see in the pictures. At this time they had developed a root and were starting to sprout. Hope this helps. Mrs. Lochridge

I'm impressed with the experiment you did with lima beans! I'm sure the children were fascinated! I’m retired now but taught for many years. In my combined first and second grades, we also did experiments with Lima Beans, but with another approach. Please see my blog for experiments with Lima Beans that I did for years. Children really loved these experiments. http://peggybroadbent.com/blog/index.php?s=Plant+Experiments+with+Lima+Beans+for+First+and+Second+Grade

We do a variation on this using clear plastic cups. Depending on the size of cup add 2-3" of soil and then put 1-3 beans against the side of the cup and add more soil. The students can watch the bean sprout and grow along the side of the cup. May have them do this, too, in order to dissect the bean. In the past we have only soaked them overnight to observe the change and split the bean to identify the embryo.

Hi should i plant them in a bag or in a plastic cup? and how long does it take to grow?

I am a pre school teacher of a two year old class and our class did the project and it turned out great. we hung our bags in our classroom window and we found that the window that got the most sun grew the better plants.Then we planted the bean in dirt and they still grew strong. cant wait to see how big the plants get. Mrs.L.Mack

Thank you for the activity! I plan to use this in the next few weeks! This seems to have a better turnout than many others I have looked up! Thanks again!
