In Year 5 science, we have been learning about forces, including friction and air resistance. To put our learning into action, we designed and tested balloon rockets. First, we made a prediction about how far and how fast our rocket would travel. We thought about how friction on the string and air resistance would slow the rocket down.
During the experiment, we released the balloon and observed what happened as the air pushed the rocket forward. Some rockets travelled further than others, depending on how much air was inside the balloon and how smooth the string was.
In our conclusion, we discovered that air resistance and friction affect how objects move. The more friction or air resistance there was, the slower the rocket travelled. This experiment helped us understand how forces work in real life and it was a fun and exciting way to learn!
