19. Fireproof a balloon.

BurningSteve Spangler

A balloon will obviously pop when touched to a hot flame, right? Not if you put some cold water in it first! Kids will be so amazed they won’t even realize they’re learning about the heat conductivity of water.

20. Experiment with balloons and push pins.

Pins Stem Little Explorers

A pin pops a balloon in no time flat, so what happens when you place a balloon on a table full of them? Once again, the answer won’t be quite what your students expect until you explain the science of distributed pressure.

science activities for preschoolers balloons

STEP 3: Tie the end to seal the balloon.

STEP 4: Hold the balloon at the stem end in your hand like a bowling ball and begin to spin it in a circular motion.

What do you hear? What does the hex nut do?

science activities for preschoolers balloons

THE SCIENCE

What happens to the hex nut in the balloon when you spin the balloon around? The hex nut may bounce around at first, but it soon begins to roll around the inside of the balloon.

It is the round shape of the balloon that causes the hex nut to move in a circular path. The force at work here is ‘centripetal force’. It is a force placed on a body that makes it follow a curved path.

What about the screaming sound? The hex nut has six sides with flat edges, which cause the hex nut to bounce or vibrate inside the balloon. The screaming sound you hear is caused by the sides of the nut vibrating against the inside wall of the balloon.

Extend the activity by varying the shape of the balloon or the type of object inside the balloon. Can you make a sound with other objects?

Balloon Rocket Race a Super Simple Science Experiment

Move & Learn Science Toddlers Grade School Kindergartners Preschoolers Balloons Experiment Outdoor Straws 9 Comments

Have a blast with your little astronauts and embark on an exciting balloon rocket adventure!

It’s an exhilarating combination of fun, science, and a little friendly competition. With just a few simple materials, you can launch your way into a world of learning and excitement.

This is a super simple science experiment with vertical balloon straw rockets for kids.

Teach kids about Newton’s third law of motion or simply have some fun!

This is a super simple science experiment with balloon rockets for kids. Teach them about Newton’s third law of motion or simply have some fun!

My kids just love balloons .

Recently we started showing my son how balloons fly crazy when you don’t tie them off and just let them go.

I was watching TVO Kids with them the other day. I love watching Bitz and Bob because they always have some kind of science experiment to do with your kids at the end.

On this particular episode they did balloons on a string.

This instantly reminded me of a balloon rocket science experiment from when I was a kid!

I grabbed the supplies and took my kids outside to give it a try a few days later since it was raining that day.

At first we just made our balloon rockets with string, straws, yarn and packing tape. Since that’s what I had on hand.

Super simple science experiment with vertical balloon straw rockets to teach kids about Newton’s third law of motion or simply have some fun!

Later we turned them into real rockets by adding fins with little pieces of paper.

Super simple science experiment with vertical balloon straw rockets to teach kids about Newton’s third law of motion or simply have some fun!

I also realized that thinner tape strips work much better. So we switched to using thin painters tape!

Also recommend packing tape as it adheres strong enough to stay on but not strong enough to pop the balloon.

For This Balloon Straw Rocket Science Experiment You Will Need:

Supplies needed to make your own balloon straw rocket science experiment.

  • long piece of string or yarn
  • painters tape
  • two clothespins (optional)
  • paper (optional)

Setting up Your Balloon Rockets Science Experiment

Find a location for your balloon rocket course.

Set up your course for balloon rocket race activity

First thing you need to do is decide where you are setting up the experiment course.

We did our balloon rocket race between two trees.

But this can be done indoors also between a chair and a doorknob or between two chairs.

Turn Straws Into Rockets (Optional)

create straw rocket base for balloon race experiment

Next, cut a piece of string or yarn long enough to go from one end of the course to the other and back again.

Or two pieces long enough to go from one end to the other and be tied at each end. (But don’t tie them yet!)

Next you need to get the straws prepared.

If you are choosing to decorate your balloon rockets then here is what we did. Older kids can do this part on their own!

Cut 3 triangles to use as the fins on the back of the balloon rocket. You want to have one of the corners a 90 degree angle (approximately).

Tip: we made this easy by taking a square and cutting the corners off diagonally.

Getting fins ready to turn straws into rockets

Next you want to tape 3 of these onto one end of a each straw to make it look like a rocket.

I taped on both sides of each triangle to make sure they would stick out and not just fall flat onto the surface of the straws.

If your kids love science and balloons as much as mine then they will love this Blowing Up a Balloon Experiment !

Setting up Your Balloon Rockets Course

Super simple science experiment with vertical balloon straw rockets to teach kids about Newton’s third law of motion or simply have some fun!

Now it’s time to tie up the balloon rocket course.

Attach the string(s) to your finish line or ending point.

Thread the straws onto the other two ends of the string(s) that are not tied on yet.

Tip: If you made them look like rockets then make sure to have them both point towards the tied end.

Once the straws are on you are free to tie the other ends to your starting points.

Super simple science experiment with vertical balloon straw rockets to teach kids about Newton’s third law of motion or simply have some fun!

Tips: Make sure there is enough room between the starting points for the balloon rockets to not be touching once they are blown up and taped on. Also make sure the string(s) is tight enough that they are straight and not droopy.

Note: If you have more than two children planning to participate you can always make more course lines by adding another string to the ending point and tying the other end to a 3rd or 4th starting point with more straws and balloons!

Now Tape Your Balloons to the Rocket Course

Super simple science experiment with vertical balloon straw rockets to teach kids about Newton’s third law of motion or simply have some fun!

Your final step in preparations will be attaching the balloons to each straw!

First thing to do is blow up your balloons. They need to be attached to the straw when fully blown up.

This is where I found the clothespins to be helpful!

TIP: After I blew each one up I would give the end a tiny twist and pop a clothespin one at the twist to stop it from deflating. (Optional as we did it many times before I thought of it.)

Once the balloons are blown up tape to the straws with the openings facing the back of the rockets.

I actually did them backwards the first time. Oops!

This is how NOT to tape the balloons on

Tip: If you do them backwards don’t attempt to take the tape off! It’s better to let them deflate and hope that the tape will come off on its own… my balloons popped and I had to grab some more.

This Hidden Colors Experiment is another one of my sons absolute faves!

Vertical Balloon Rockets Science Experiment 3-2-1-Blastoff!

Super simple science experiment with vertical balloon straw rockets to teach kids about Newton’s third law of motion or simply have some fun!

You are now ready to start the balloon straw rocket race!

Have your kids each hold one balloon and have it as far back on the starting line of the string as possible.

Or if only one child is participating they can hold one in each hand or you can hold one.

Start your countdown!

3-2-1-BLASTOFF!

Finally, let go of the ends of the balloon rockets at Blastoff and watch them zoom to the other end of the string to the finish line!

3-2-1-Blast-Off! Balloon straw rocket race experiment for kids.

This is a great time to talk about Newton’s 3rd Law of Motion : Every action has an equal and opposite reaction.

The air blows out of the balloon (action).

The balloon rocket moves forward (reaction).

Balloon rocket science experiment for kids. super simple and fun.

Also take the time to discuss what the balloons did. Did it go straight? Spin around the string? Get stuck half way?

Tip: Having the balloons different colors helps to keep track of your results if you choose to document this like a real science experiment.

Gross motor fun chasing after balloons outside.

We did this balloon straw rocket experiment tons of times over!

Have your kids bring the straws back to the starting point and blow up the balloons to go again!

Bring your rockets back to the start line and race again and again.

If the balloons fall off, no worries, just tape them back on.

And if they don’t fall off then have fun blowing them up still attached to the string. Lol.

Blowing up balloons for preschoolers so we can race them again

Extend the Science Experiment

Try different set-ups to see what happens.

  • What happens if one is blown up smaller than the other?
  • What if you tape the balloon on sideways or on an angle? Does it spin?
  • What if you don’t actually let go completely and just let the air out? Does it make your hair or clothes move?
  • Try different sizes and shaped balloons.
  • What if the triangle fins are on an angle?
  • Try less fins or no fins?
  • What if the fins are really big or smaller?
  • Cut the string and stick the front of the straw into the end of the balloon and use a small elastic to secure it. Blow it up using the straw and then watch it fly freely. See where it goes like Mombrite did.

Keep going on the topic of actions having an equal and opposite reaction.

One of my favorite things to do each year in my classroom was to order Caterpillars and watch them grow as a class. Then we added milkweed to our garden and have monarchs visit often to lay eggs and we get to see them grow again and again.  

It’s really quite magical every single time. We thought it might be fun to see if we can create our own STEM Challenge to turn caterpillars into butterflies and found a fun twist on this balloon science activity.  A creative caterpillar to butterfly science activity!

Are you ready to see how it’s done? 

Balloon Butterfly Science Experiment

The kids will want to do this again and again, which it great since it only needs a few items from your kitchen.  Here’s what you’ll need to get started.

Materials for Butterfly Science Activity

  • Black Permanent Marker
  • Baking Soda
  • Empty clear container
  • Measuring spoon
  • Safety Goggles

Create your own caterpillar and Butterfly for STEM Activity

Directions for Butterfly STEM Challenge

1. DRAW  a butterfly onto a balloon on one side.

ADD A SURPRISE ELEMENT: The first time I did this with my girls I hid the butterfly and just showed them me attaching the filled caterpillar to the bottle so it was a surprise when the butterfly showed up.  They were so surprised!!!  

Something to think about to add to the FUN FACTOR of this Science Activity.  Then, of course, they wanted to create their own and I allowed them to play around with levels of amounts to create a Challenge for them.

2. Draw a caterpillar onto this same balloon on the other side.

Balloon Science Activity with Butterflies and Caterpillars

3. Fill the empty plastic container with vinegar. You only need a little bit to make this reaction.

4.  Then fill the balloon with baking soda by inserting a funnel into the opening and placing a spoonful into the funnel to fill inside of the balloon.

5.  Attach the balloon to the plastic container with vinegar. Careful not to spill any of the baking soda inside of the container.  When you hang the balloon be sure to hang it on the caterpillar side and talk about how the caterpillar forms a chrysalis that hangs.

Mixing Vinegar and Baking Soda to make Butterfly Balloon

6. Now it’s time for the STEM Challenge!!!   Can make your butterfly grow?

Encourage your child to LIFT UP the caterpillar balloon and allow the baking soda to fill into the container.  WATCH and see what happens next!!!! 

Balloon Butterfly STEM Experiment for Kids

7.  SURPRISE!  You balloon will fill up with the gases released from the chemical reaction between the vinegar and baking soda.

How does it work? When baking soda and vinegar mix, they release carbon dioxide (this is the same gas that is in the bubbles in your carbonated drinks).

Hands-On Teaching Ideas

Balloon Rocket Science for Kids

Easy science for kids! My kids always get excited when they know that we are doing a science experiment.  “It’s like magic, but better,” they tell me.

Children are naturally curious about the world around them. They want to learn and they often have a lot of questions about things they have seen.

Rocket science is often a topic that comes up when I teach. Many young children are fascinated by rockets and how they work.

Today we talked about how a rocket ship blasts off into space and then I had my kids guess how they thought the rocket was able to do this. 

This balloon rocket science experiment is a great activity for home or school and perfect for outdoor learning.

I have done this balloon rocket experiment with children as young as four and again when I taught grade two as we covered our science program. Even older children will love the experiment, and the learning that goes along with it.

I have done the experiment two different ways. You can use one balloon and have everyone watch together, like a presentation, or give small groups the materials and let them experiment together.

science activities for preschoolers balloons

Personally, I always love when I can give children the materials, and the instructions, and they can learn and experiment with their own hands. In my opinion, this is when the best learning takes place.

science for kids

All science experiments should always be done with an adult supervising and involved in the activity. Make sure to do the activity in a safe spot and make children participating are old enough to use the materials.

You don’t need any special or expensive materials to do this experiment. All of the materials are fairly simple and you may already have many at home.

The only suggestion that I would make as far as materials is that large, smoothie type straws work best.

Although you can’t replicate actual rocket science for kids, this experiment does give kids a basic idea of how rockets work.

Plus it is just a really fun, hands-on science for kids experiment that gets kids excited as they learn about the world around them, and science.

science for kids

With this experiment, you will create your own model that works in a similar, but  very basic way compared to a rocket, but done in a way that is easy for kids to understand. 

Even young children will have fun with the experiment. Don’t worry if kids don’t understand the technical science behind it, that’s not the intention.

Experiments, like this, simply give children a basic understanding of rocket science – and hopefully a love of science.

I always enjoy preparing activities in science for kids because it is hands-on and kids love it!

Rocket Science Worksheets

When I do this experiment, I have children follow along and predict what they think is going to happen on worksheets.

This encourages their writing development and adds to their understanding by putting their thoughts into words.

science for kids

The worksheets I created to align with this experiment are available. (Click “The Power of Air” image below).

Without the worksheets, you could simply have children keep track of their predictions and observations and results as they do the experiment.

science for kids

Rocket Science for Kids Steps

First, I blew up a balloon and asked everyone what would happen if I let go of it.  I then let it go!  They loved watching it zip around he room and then fall to the ground. 

We used this idea of movement for our experiment. 

I then tied one end of a piece of string to secure it. Next I slipped the straw through the string and brought the straw to the end.

Then I tied the other end of the string to the other end of the hall. Make sure to tie the string so that the string is tight and straight.

science for kids

If the string is not tight, the balloon will not go as far. 

Next, I blew up a balloon, but did not tie it, and taped it to the straw as I held the end closed. 

The balloon was now filled with gas (air).

Make sure to have the end that you are holding face towards the wall.

science for kids

I had children guess what they thought was going to happen when I let go of the end of the balloon.  After a few guesses, I then let it fly! 

The balloon zoomed across the string! It should go several meters depending on how full you fill the balloon. 

science activities for preschoolers balloons

When you let the end go, the escaping air causes a force on the balloon.  All of the air is forced through the small hole on the balloon which causes the balloon itself to react and zoom in the other direction. 

Much like a rocket in blast off!

Science for Kids Extension Activities

Generally after children have seen the balloon zoom across the field or room, they are excited and want to learn more.

This is a great opportunity to try out some of the questions they have and things they are curious about.

Also, if your balloon did not go far, it is a good chance to talk to children about why they think it didn’t go far.

Was there too much air in the balloon? Was the string not tight enough?

science for kids

I suggest trying out the experiment a few times so that you, hopefully, get consistent results.

Let different children hold the string or let the balloon go. They will enjoy being part of the experiment.

Once you have done the experiment a few times, you can try blowing up the balloon more and seeing what happens.  What happens if you only blow it up a bit?

The problem is that if the balloon is bigger, it sometimes spins and does not go as far.  This leads to great discussion as to why and how we could fix this problem. 

When our huge balloon ended up spinning around and not going very far, I asked my students at schoolhow they thought that we could solve the problem.

Their solution was to attach a small weight (a penny) to the bottom to keep the balloon from spinning.  What a great idea!

This activity sparked many discussions and future experiments. Children were really curious what would happen if you attached 2 balloons and what about 3? 

What would happen if you used the huge balloon?  What would happen if you held the string up so that the balloon traveled down as it moved across? 

The things that kids wonder, end up being the best part of teaching science for kids.

Another idea that we tried out when we did this science experiment at home was giving each of my kids a balloon. They choose how full they wanted their balloons and they spent a long time racing them against each other.

My favorite part was the experimenting that happened between each race as they improved their balloon (with coins etc.) and tried different amounts of air in the balloon.

Each time they were simply trying to make their balloon go further and faster, but they were also being little scientists as they experimented, tested and improved on their their ideas.

Since I initially did this experiment at school, we worked though each step together and had follow up sheets.

Below is the “Scientific Method” rocket science booklet that I use with my students.

Tips for Doing Preschool Science Experiments

Doing science activities with preschoolers can be a lot of fun, but you also need to always ensure safety first. But guess what? Even that part can be fun! I highly recommend buying children’s lab coats and lab safety glasses (in fun colors!) , for your preschoolers. It not only will help protect your kids, but it taps into children’s imaginations and helps them embrace the idea of being little scientists.

When doing any of these activities, proper adult supervision is required at all times, and ensure you adapt the activities as required to meet children where they are at maturity and ability wise. We want science to be fun and safe!

Another tip, always assume things are going to get messy! Cover areas and work in spaces when you can let kids explore freely without worrying about the mess. For some of these experiments, you can even head outside!

Whether you are at home and doing some homeschool science or looking for some classroom experiments, there are lots of fun science activities you can do with your kids!

  • But I ignored the experts on one thing and let my kids have unlimited screen time.
  • My teenagers have still turned out great. 

Insider Today

From day one as a mom, I wanted to do everything right to ensure my kids were happy, healthy, and successful. I read countless parenting articles and books with tips that would supposedly help my kids live their best lives. I followed most of the rules religiously: I read to them daily, talked to them about their feelings, and ensured they were getting time for exercise and exploring creativity.

A nagging sense of doubt started to creep in when I tried to follow some rules, though. They didn't all seem doable, and some rules were too old-fashioned for today's society .

The rule-breaking began early in my parenting years

My toddler would wake up three or four times a night, and the only way either of us could get a full night's sleep was by co-sleeping .

According to the experts, that was a big no-no, but in my eyes, co-sleeping was healthier for both of us. Instead of being cranky in the mornings, we were well-rested and happy.

By the experts' standards, I was also a complete failure in one big way: limiting screen time .

The experts would have been horrified about the screen time I let my kids have

I didn't set a screen-time limit for my kids because, like it or not, screens are a part of our society. While other parents I knew were giving each other knowing nods about the negative effects of screen time , I let my kids have as much as they wanted — as long as they were still getting exercise, socializing, behaving, and bringing home good grades.

My kids were playing video games by age 3 and watching cartoons before they could walk. But we also emphasized spending time together as a family and making sure we all had enough exercise. I had plenty of moments of intense self-doubt when I wondered if I was crazy for not being concerned about screen time.

As each year passed, though, I became more confident that screen time wasn't necessarily the enemy that parenting experts were making it out to be, as long as I also encouraged my kids to be balanced, well-rounded people .

As they have gotten older, I still haven't changed my parenting style

I still don't care whether my kids have a four-hour gaming session one day or watch two movies back-to-back on a day they feel like being lazy. They get straight A's in school, volunteer in our community, and are happy, kind, and healthy.

They both have plenty of friends and are involved in sports and other extracurriculars at school . Our family bond is strong, and we spend lots of time together, both on screens and off. In addition to lots of screen time, we ran 5K races together and went on epic family vacations .

My children are rocking it — despite all their screen time

Now, my daughter is a junior in high school and is academically ranked No. 1 in her class. She has volunteered more than 150 hours in our community so far, works as a softball umpire during the summer, was selected as the class homecoming representative her sophomore year, and is a three-sport athlete . And guess what? She still enjoys playing computer games for hours at a time.

My son is in his freshman year at a private college and is majoring in computer science. He just made the dean's list. During high school, he spent anywhere from four to five hours a day on screens when writing code, playing games, and watching television. He was also on the track and cross-country teams and was named student of the month.

In the six months before my son left for college, he and I watched all 15 seasons of " Supernatural " together. That was a lot of extra screen time, but it became our special bonding time, and we still quote that show to each other in texts and conversations .

I wouldn't change a thing about ignoring expert parenting rules

Ignoring the rules has worked out wonderfully for my family. My kids are both at a healthy body weight, are smart, love spending time with their family, enjoy helping others, and are extremely happy.

As a parent, what more can I ask for?
