As part of our Incredible Inventions topic, year 4 have made balloon powered cars. The children created a symmetrical shape for the body of their car, thinking about the effect of streamlining.They decorated them and used a balloon to power them.

The grand finale was a class race. Unfortunately, some fared better than others, but this led us to think about what was stopping the cars from travelling as well, and what we could do to improve our design, using the knowledge we gained from our science topic of Friction.

As you can see from the photos, we had fun racing them even if they didn't go very far. Lewis Hamilton need not worry just yet!
