Leak Proof Bag

Crystal — Sat, 07 Oct 2023 12:14:00 +0000

Can you poke a hole in a bag full of water without losing even one drop? Once you learn the science behind this leak-proof bag experiment, you’ll be ready to poke holes in a bag full of water while holding it over somebody’s head!

It’s the perfect compliment to our 30 Science Experiments you can find in our shop!

Getting Ready

Since this science activity involved water, we decided to do it outside, but it would have also been perfect for bath time.

Before heading out the door, we gathered a few simple supplies to perform our leak proof bag trick:

Zipper storage bag
Water
Several sharpened pencils

We filled the zipper storage bag about 2/3 full of water. After squishing out the air, we made sure the zipper was sealed tight.

I asked my kids what they thought would happen if we stabbed a pencil through the bag. I always love to have them make a hypothesis and then see if it really happens. Sometimes the results can be surprising!

Using the sharp end of one pencil, I quickly pushed it through the bag. It went in one side and out the other – without spilling a drop!

To make it even more fun, I held the bag of water over my son’s head while I pushed more pencils through it. He was so scared he was going to get a shower at the park!

Once my kids saw that the bag wasn’t going to explode all over them, they were courageous enough to push some pencils through themselves. We added quite a few! We even squished the water gently around the bag and turned it upside down without spilling a single drop of water.

The Science Behind It

Plastic bags are made of a polymer called low-density polyethylene. Polymers are long chains of molecules. The tip of the pencil squeezes between the chains without breaking them but the chains’ flexible property helps to form a temporary seal against the edge of the pencil. This enables a pencil to pierce the bag without losing even one drop of water!

Sprout House Science Experiment – Watch Seeds Grow!

Malia — Sun, 02 Jul 2023 17:00:00 +0000

Have you ever wanted to grow a tiny garden right in your classroom? With this Sprout House experiment, kids get to build their own little greenhouse, plant seeds, and watch them sprout before their eyes! This hands-on STEM activity is the perfect way to teach kids about plants, germination, and engineering—all in one fun project.

What is a Sprout House?

A Sprout House is like a mini greenhouse, but instead of glass and metal, it’s made out of sponges! That’s right—plain old sponges! The sponges hold water, helping the seeds sprout and grow. Kids will design, build, and care for their very own tiny plant house while learning what seeds need to grow.

What You’ll Need

Gather a few simple supplies:

4 plain kitchen sponges – These will become the walls and roof of the house.
Scissors – For cutting the sponges.
Toothpicks – To hold everything together.
Glue (optional) – If you want extra support.
A shallow tray or plate – To hold the Sprout House.
Fast-growing seeds – Try wheat berries, chia seeds, or alfalfa.
A spray bottle – To keep the seeds moist.

How to Build Your Sprout House

Step 1: Build the Walls

Take one sponge and use it as the base of the house.
Cut another sponge in half to make two side walls.
Cut a third sponge in half—then cut one half again to make the front and back walls.

Step 2: Put It Together

Attach the walls to the base using toothpicks.
Press the toothpicks in deep so the walls stand up tall!
Cut the last sponge in half to make roof panels and attach them on top.

For the roof, you can use toothpicks as connectors again, but securing the roof to the walls and to each other can be a bit tricky. If needed, you can use a hot glue gun to hold the roof in place.

Step 3: Add the Seeds

Spray the sponges with water until they’re damp but not dripping.
Sprinkle a thin layer of seeds on the roof and walls.
Gently press the seeds so they stick to the sponge.

Chia and alfalfa seeds are a fun combo. Simply put about a tablespoon of seeds in a small dish and add a little water to create a seed slurry. Chia seeds absorb a lot of water and become gummy, which actually makes spreading the seeds much easier.

Step 4: Take Care of Your Sprout House

Place the house on a tray or plate to catch any extra water.
Keep it in a bright spot (but not direct sunlight).
Mist it several times a day with the spray bottle to keep the sponges moist.
Watch closely—in just a few days, the seeds will start to sprout!

What’s the Science Behind It?

This experiment teaches two cool science concepts:

Plants need water, air, and light to grow.
- The damp sponges act like soil, keeping the seeds wet so they can sprout.
- The bright spot provides light to help the plants grow strong.
Seeds go through germination.
- When seeds absorb water, they wake up and start growing!
- Tiny roots appear first, then little green shoots pop up.

Building Shapes STEM Cards

Rosey — Sat, 01 Jul 2023 17:09:17 +0000

Kids will have an awesome time building popular 2D and 3D shapes with these free STEM activity task cards!

This post contains Amazon affiliate links.

Getting Ready

I began by printing the the task cards on cardstock to give them extra durability.

Then, I ran them through my laminator and cut along the dotted line in the center of each page to separate the halves.

I grabbed a ball of playdough kids could use to build the 3D shapes and filled a small basket with a variety of rainbow-colored popsicle sticks.

(The unstained kind would work well, too. They are available in a variety of sizes from mini to jumbo size!)

STEM Activity: Building Shapes

I spread out the 2D shape task cards around one table and placed the basket of popsicle sticks in the center. The kids took turns making each shape.

Later, we talked about shape properties like the number of corners (vertices) and sides (edges) on each one.

On another table, I challenged kids to make 3D shapes. After placing one card at each seat, I placed a basket of popsicle sticks and playdough in the center.

The kids used the playdough to join each of the sides together which involved a lot of problem solving.

One of the kids figured out that he needed a bit more playdough so that the popsicle sticks would stay in place, but not too much because or his cube would fall over!

For the 3D shapes, it’s fun to include a variety of materials such as popsicle sticks, colored matchsticks and straws. That way kids can explore different materials and discover which ones are easier for building.

For instance, straws are sometimes a bit easier for modeling because they are lightweight and can be easily cut into different lengths but they’re not as strong and durable as craft sticks. The best part of this STEM activity is that you can tweak it many different ways!

Famous Landmarks STEM Challenge

Malia — Mon, 26 Jun 2023 12:36:36 +0000

My kids are ~~in love with~~ OBSESSED with LEGOs, so I was excited to create a STEM challenge that would stretch their building skills. Voila! That’s how this famous landmark STEM challenge was born.

It’s a cult-favorite! And it’s perfect to use in STEM centers or makerspaces. Grab your set in our shop!

Prepping the STEM Challenge

Prepping the activity took just a few minutes. I printed the challenge cards on cardstock to give them extra durability and cut apart the pieces.

To help ensure that our set stayed together, I punched a hole in the upper left-hand corner of each card and bound them with a ring.

Since I wanted to sprinkle in a little geography into the activity, I printed the map and laminated it for easy reuse. Then, I marked the four landmarks I was going to have the kids focus on that day: the White House, Eiffel Tower, the Giza Pyramids and Kukulcan Pyramid.

(Using a vis-a-vis marker on the lamination made it easy to wipe the map clean when we built our next set of landmarks later.)

I printed one planning sheet for each child and we were ready to begin!

Building Famous Landmarks

For this first day, I wanted the kids to work through the complete process of planning and designing their structure before diving into the LEGOs, so I gave each of them a planning sheet.

Big Brother (age 6.5) completed the page on his own but I helped Middle Brother (age 5) by writing down the answers he dictated to me.

Once the boys had a solid plan in place, they started building their structures. Middle Brother built a replica of Kukulcan El Castilla.

While Big Brother worked on the Eiffel Tower.

The STEM challenge cards were as motivating as I’d hoped!

Walking Water Rainbow Science Experiment for Kids

Malia — Tue, 23 May 2023 15:00:00 +0000

Ever wondered how water can “walk”? Try this magical rainbow experiment!

Science experiments don’t have to be complicated to be fun and educational! This walking water science experiment for kids is a simple but fascinating way to explore capillary action, color mixing, and the properties of water. Perfect for preschoolers and elementary students, this hands-on activity encourages curiosity and critical thinking.

In this guide, you’ll find step-by-step instructions, the science behind the experiment, and ways to extend the learning experience!

What is the Walking Water Science Experiment?

The walking water science experiment for kids is a simple demonstration of capillary action—the process that allows water to move through materials like paper towels, plants, and even your own body’s veins! By using colored water and paper towels, kids will watch in amazement as water “walks” from one cup to another, creating a beautiful rainbow effect.

This experiment is ideal for preschoolers, kindergarteners, and early elementary students, offering a fun, visual way to introduce key scientific concepts.

Materials You’ll Need

To set up your walking water rainbow experiment, you’ll need just a few household items:

6 clear cups or jars
Paper towels
Water
Food coloring (red, yellow, and blue)
A stirring stick or spoon

Step-by-Step Instructions: How to Do the Walking Water Experiment

Follow these simple steps to create your walking water science experiment for kids:

Step 1: Prepare the Cups

Line up six clear cups in a row.
Fill every other cup with water (cups 1, 3, and 5 should have water, while 2, 4, and 6 remain empty).

Step 2: Fold the Paper Towels

Take a paper towel and fold it lengthwise several times.
Place one end of the paper towel in the colored water and the other end in the empty cup next to it.
Repeat this process, creating a bridge between all cups.

Step 3: Add the Food Coloring

In cup 1, add red food coloring and stir.
In cup 3, add yellow food coloring and stir.
In cup 5, add blue food coloring and stir.

Step 4: Watch the Water Walk!

Wait and observe! Over the next 30 minutes to a few hours, you’ll see the water slowly “walking” up the paper towels and into the empty cups.
As the colors mix, they form secondary colors (green, orange, and purple), creating a rainbow!

The Science Behind It

This rainbow science experiment is as magic as the science behind it. The colored water travels up the paper towel by a process called capillary action. Capillary action is the ability of a liquid to flow upward, against gravity, in narrow spaces. This is the same thing that helps water climb from a plant’s roots to the leaves in the tree tops.

Paper towels, and all paper products, are made from fibers found in plants called cellulose. In this demonstration, the water flowed upwards through the tiny gaps between the cellulose fibers. The gaps in the towel acted like capillary tubes, pulling the water upwards.

The water is able to defy gravity as it travels upward due to the attractive forces between the water and the cellulose fibers.

The water molecules tend to cling to the cellulose fibers in the paper towel. This is called adhesion.

The water molecules are also attracted to each other and stick close together, a process called cohesion. So, as the water slowly moves up the tiny gaps in the paper towel fibers, the cohesive forces help to draw more water upwards.

At some point, the adhesive forces between the water and cellulose and the cohesive forces between the water molecules will be overcome by the gravitational forces on the weight of the water in the paper towel.

When that happens, the water will not travel up the paper towel anymore. That is why it helps to shorten the length that colored water has to travel by making sure your paper towel isn’t too tall and making sure you fill your colored liquid to the top of the glass.

Rainbow Science Activity Extensions

Turn this demonstration into a true experiment by varying the water level (volume) you start with and seeing how long it takes the water to reach the empty glass.

Or start with the same volume of colored water and change the brand, type (single vs double ply, quilted vs not) or length of paper towel to see how long it takes for the water to “walk” to the empty glass.

You could even use the same volume of water, same length and brand of paper towel but vary the height of the filled glass, by raising them up on books, to see how that affects the speed of the water as it “walks” to the empty glass.

Have you had enough fun with the paper towels? Try using other paper products to see how the type of paper effects the results. Try toilet paper, printer paper, newspaper or a page from a glossy magazine. What do you predict will happen?

Not Working?

If you aren’t seeing much movement within a few minutes, it may be that you need to add more water to your colored water glasses. It really needs to be almost at the top for the water to walk quickly. So try topping off those glasses and seeing if that gets things moving.

If you see the water moving up the paper towel but it seems like it’s taking forever, it may be the type of paper towel you are using. You want a paper towel that will really hold a lot of water. We have used Bounty Select-a-Size and Target’s Up and Up Brand Select-a-Size with success.

It really is worth the extra effort of trying different cups and paper towels to get this activity to work. And once you have had success, don’t throw out those beautifully-colored paper towels or the colored water! We gently squeezed out our paper towels and let them dry in a heap on a baking sheet. We ended up with gorgeous tie-dyed looking paper towels to use for crafts and we used the leftover water as watercolors for painting with later.

Teaching kids about weight and measurement doesn’t have to be boring! With these Hands-On STEM Weight Challenges for Kids, students will explore weight comparisons through fun, interactive activities that encourage critical thinking and hands-on learning.

Whether you’re a teacher looking for a creative classroom activity or a parent wanting to engage your child in STEM learning at home, these printable Weight STEM Challenge Cards provide an exciting and educational experience.

Grab your free set below and then hop over and snag an entire YEAR of playful, done-for-you challenges for endless STEM inspiration!

This post contains Amazon affiliate links.

Why Hands-On STEM Weight Challenges Work

Many kids struggle with abstract math concepts like measurement. By making weight comparisons a hands-on experience, students develop a deeper understanding of the subject. Here’s why interactive STEM activities are so effective:

They make learning fun! – Kids naturally enjoy experimenting and testing ideas. These challenges turn learning into a game.
They build real-world connections – Measuring objects they see every day helps kids understand how weight works in the world around them.
They encourage problem-solving – Kids predict, test, and analyze their results, strengthening critical thinking skills.
They keep students engaged – Hands-on activities prevent boredom and allow kids to learn by doing rather than just listening.

These weight measurement challenges not only teach math and science concepts but also promote curiosity and a love for learning.

Getting Ready for the STEM Weight Challenge

Before jumping into the activity, I prepped everything ahead of time to make it easy for my students to get started.

1. Printing and Laminating the Challenge Cards

To prep, I printed the STEM challenge cards (you can download them below) and laminated them. Laminating makes the cards reusable and extra durable—perfect for a classroom where little hands can be rough on materials!

Since my kids are notorious for misplacing cards, I punched a hole in the bottom right-hand corner of each one and hooked them together with a binder ring. This simple trick keeps them organized and easy to flip through.

2. Gathering Materials for the Challenge

Next, I grabbed a balance scale (we used this one from Amazon), along with a variety of small objects for the kids to weigh. Here’s what we used:

3 crayons
2 pencils
1 pair of scissors
2 pink erasers
5 Unifix cubes
2 markers
2 counting bears
5 coins (we used pennies, but any coin would work)
5 paper clips
1 pencil
2 dice

These everyday items are perfect for weight comparisons because they come in different sizes and materials. You can substitute with similar objects if needed.

How to Use the Weight STEM Challenge Cards

Once everything is prepped, it’s time for kids to dive into the challenge!

Set up learning stations – Place the balance scale and the challenge cards at a table or designated area in the classroom.
Assign small groups – Pair students up or put them in small groups so they can work together and discuss their findings.
Start exploring! – Give each group a challenge card and have them find the objects listed.
Make predictions – Before using the scale, ask students to guess which object they think will be heavier.
Test and measure – Students place objects on the balance scale to see the actual results.
Record observations – Have students write down or discuss what they learned from each challenge.

Encourage kids to talk about their results and compare their predictions to what actually happened. This builds reasoning skills and helps them understand that science is all about experimenting and discovery!

Fun STEM Weight Challenges to Try

Here are some examples of weight comparisons that make great STEM challenges:

Which weighs more: 2 markers or 5 Unifix cubes?
Are 3 crayons heavier than 5 paper clips?
Which is lighter: 2 pink erasers or 1 pair of scissors?
How does the weight of 5 pennies compare to 2 counting bears?

These challenges encourage curiosity and discussion. Kids love making guesses, testing their ideas, and seeing real results.

Making It More Challenging

Want to extend the activity for older students or kids who need an extra challenge? Try these ideas:

Ask students to estimate the weight of each object in grams before measuring.
Have students rank objects from lightest to heaviest.
Introduce additional variables like stacking items together or using different materials (plastic vs. metal).
Incorporate math skills by having students record their findings in a chart or graph.

By adding extra layers of challenge, students continue developing their math and problem-solving skills while having fun.

Discussion Questions to Spark Learning

After students complete the weight challenges, gather them together for a group discussion. Here are some great questions to ask:

What surprised you the most about the results?
Did your predictions match the actual weights? Why or why not?
What patterns did you notice in the objects you measured?
If you could measure different objects, what would you choose?
Why do you think some materials are heavier than others?

Encouraging kids to reflect on what they learned helps solidify their understanding and gets them excited to explore more STEM activities!

Straw Bridges

Malia — Tue, 09 May 2023 17:00:00 +0000

Building straw bridges is a fun way to strengthen kids’ science, technology, engineering and math (STEM) skills. With just a few simple supplies, they can design a load bearing bridge just like the ones they drive across in cars!

What will your class come up with!? Create more amazing STEM projects with our Epic STEM bundle!

This post contains an Amazon affiliate link.

Learning About Bridges

Before diving into our engineering project, I wanted to introduce the kids to some bridge basics so I pulled out a copy of Bridges! Amazing Structures and shared the major highlights. (The book is written for grades 2 to 6, so I needed to be selective to keep it age-appropriate.)

As we read, we kept track of what we learned by adding to a simple anchor chart showing the five bridges we were focusing on:

arch
beam
suspension
cable-stay
truss

We chatted about how each design evenly distributes loads through specific points using a combination of pulling forces (tension) and pushing forces (compression).

For instance, in a cable stay bridge, cables direct the weight of the traffic and the bridge itself onto the support beams in the middle (called piers) and the supports on either end (called the abutments).

Building Straw Bridges

Once the kids had a solid understanding of how bridges work, they were eager to jump in and start building their own miniature versions with straws, scissors and tape.

The challenge was to build a bridge that would hold a cup of 100 pennies without falling over. This first draft held the cup when it was empty but toppled over when it was filled with pennies.

So the kids went back to work! They added more straw supports to distribute the weight and evened out the base to make the structure more steady.

Straws and tape might not be very strong on their own, but it was amazing to see how sturdy they could be when they were combined together just so!

STEM Jellybean Structures

Malia — Sat, 22 Apr 2023 17:30:58 +0000

Jelly beans + toothpicks = an afternoon of engineering fun! Students will LOVE practicing engineering skills with this hands-on (and tasty!) STEM project.

Follow the step-by-step directions below and then hop over to take our popular 5 Day STEM Challenge! (Your kids will thank you.)

Getting Ready

We’ve done this activity before using marshmallows, but those always proved frustrating as more complicated structures became unstable and collapsed.

The hard, sticky inside of the jelly beans were so much better and made some seriously stable creations.

Be careful with little ones, the hard shell on the jelly beans can be hard to pierce. While my 3 year-old didn’t have many issues, the toothpicks could slip and poke little hands.

In the beginning, I didn’t give my 3 and 6 year-old many instructions. I just wanted keep the activity open ended and let them to be as creative as they wanted to be.

STEM Project: Jellybean Structures

My 6 year-old began by constructing a series of pyramids. She made a square first and then added the triangular sides.

As she built, we talked about what 2D shapes made up her 3D shape. I’d ask her to count how many planes (flat surfaces) and how many vertices (corners) her pyramid had.

After making several pyramids, she moved on to making cubes, then joined them together to make a larger structure.

At some point, she decided that she wanted to make a stronger tower. She built a cube, a pyramid and a prism and pressed down on each to see which was the strongest. She thought the shapes that used triangles seemed to be stronger.

So she began on her second tower. At this point, I suggested testing which tower was stronger by seeing how many books each tower could hold. And the stacking began!

The first tower started leaning and the books slid off after eight books.

The next tower held a whopping 32 books before crumbling under the weight. After comparing both towers, we saw that the second tower was shorter and built with more precision. We figured it was both of these things that helped make it stronger.

We built and tested our jellybean structures for a good hour. It looks like we came up with a new equation for an awesome time!
