STEM Based LEGO® Race Cars

Beat the boredom with our fun and interactive STEM-based project! When you combine the science of balloons with the engineering fun of LEGOS®, you get a really unique activity perfect for rainy days, summer breaks, or even for a great birthday game!

Based on the fundamentals of Science, Technology, Engineering, and Math, (STEM) our race car activity can be done with just a few supplies.

Supplies:

Balloon Time Helium Tank
LEGO® car or a building block car of your choice
Assorted balloon colors (different for each child)
Notepad & pen

Instructions:

Build your car according to the product instructions *Tip* Cars with spoilers tend to work the best
Next, split participants into two even teams (Team Air vs Team Gas)
Ask each team which team they think will win and why (Team Air (breath) or Team Gas (helium) ) recording those guesses on the notepad
Have Team Air manually blow up their balloons, holding them pinched off
With assistance from an adult, inflate balloons with helium, holding them pinched off
Adult assistance may be required for then sliding the pinched off end of the balloon under the spoiler with the top of the balloon pointing towards the hood of the vehicle while keeping the end of the balloon pinched to prevent leaking
For the second round, fill new balloons with helium and again, seal them with the clothespin
Line up the cars, count down from 5, and let them go!
