Today, I continued yesterday’s activity – the Peripatus Step It Up. For the Step It Up activity, I have to build a catapult and test how far it can shoot. I first made a very simple small catapult with a clothing peg, some popsicle sticks and elastic banks to hold everything together. Then I decided to try to build a bigger version of catapult with some popsicle sticks, masking tape, wooden skewers, a plastic straw and a rubber band. Just for the fun of it and also wanted to see if it will make any different compare to the small one. My hypothesis is the bigger the catapult, it will shoot the further and higher. The smaller the catapult, it will not shoot very far.
This task was originally meant to shoot slime, but it was pouring and thundering outside, and I didn’t want to get the carpet stuck with slime, so I used some of my Go game pieces for the catapult to shoot instead. Go is a type of board game incase if you don’t know what Go is.
Conclusion: The small catapult is easy to make, launches really high, but not very far. The big catapult is really good for launching, high, far and strong. It is a bit harder to made, but it’s a lot more fun to shoot. You can hear the how hard it clashed the wall from my video.
If you have a catapult in the wild, what would you shoot at?
