DIY Balloon Powered Cars You Can Make For Science Lesson

This roundup is all about Balloon cars and making them. Not only do you get the thrill of engineering and developing the toy you get to play with it afterwards. This activity has so many opportunities for educational homeschool learning. STEAM is represented in all of these DIY tutorials. I have included different styles of Balloon race cars to give parents the flexibility of using the supplies they have on hand at home.

Science Sparks has a version of the popular Lego car that is powered by a Balloon here. Frugal fun 4 Boys also has a lego version, this car is a simpler design so more suited to younger engineers.

This one by Tots to Teens uses recycled materials making it the easiest one to source the supplies for followed by this one which uses a Juice Box and bottletops. For a recycled water bottle tanker you will need this tutorial by pbskids.org

I love the design of this Race car, actually, it’s more like a drag car but you will need old CD’s does anyone still have those in the house? This tutorial is a video and uses card board and milk lids a very simple design but has the same concept.Vroom Vroom with this simple box style car.

Don’t have the items? You can purchase ready to go Balloon Car kits too.

The Science behind it all –

A balloon-powered car is pushed forward by air escaping from a balloon. As the balloon fills with air, it adds more potential or stored energy. As the air flows from the balloon, the energy changes to kinetic energy or the energy of motion. Vehicles are powered by the escaping air from a balloon teach children Newton’s third law of motion. Minimize the drag and reduce weight to make the car go faster. Try running your car on different surfaces for speed too.

This video shows you the science, make your car and watch it here.

When my daughter was young she loved the PBS show “Peg + Cat,” and if you’ve got a fan of that show in your house this activity will be even better, but it doesn’t matter if your kids don’t already know these characters to learn about fractions with pizza.

There’s an episode of “Peg + Cat” where they are working in a pizza place and have to divide pies to put different kinds of toppings of different parts of the pie (there’s also an online game with the same concept, which I can’t believe still exists because my kiddo played it years ago).

Inspired by the episode and a companion book, Nature Homeschool developed an activity for learning about fractions and entrepreneurship using pizza. They developed a pizza shop and used the printables and teaching guide from Teacher Vision to learn more about fractions using pizza as the foundation. Their post also has a pizza order form printable you can use when you role play a pizza shop.

The Inspiration Edit also has some cute printable worksheets using a pizza to learn about fractions. And Life Over Cs has some fun printable pizza fraction activities, such as the printable fraction memory game shown here.

If you want to increase the pretend play factor with this one, you can make a pizza and toppings out of paper, cardboard or felt. Or use a paper plate as your crust and simple shapes cut out of paper to be toppings. The pretend play pizza making kit from Glued to My Crafts uses an individual slice, but you could do the same thing with a whole pie’s worth of slices.

Kids Craft Room has another fun pizza play food idea, this time using salt dough for the crust. The toppings are made out of felt so you can practice putting different toppings on a fraction of the pizza and learn as you play.
