4BT have been investigating forces and practicing their scientific inquiry skills by building and testing and improving their own lollipop stick catapults. We discovered that the more lollipop sticks you add to your catapult the further your pom pom will fly. This is because the extra sticks allow you to pull the catapult back further meaning it can give your pom pom a much bigger push into the air!
