LI: Practical build challenge to design and create a newspaper model of a catapult.

We were challenged to create a catapult using push and pull forces. The push force is when you push something away from you, and pull forces is pulling towards you.
First we got into groups and each drew our own catapult planning designs, then we chose the best one to use as our blueprint. First my group created a base by securely rolling up rolls of newspaper and taping them together. Then we made a long one to be the arm or out catapult that shoots the projectile far away using the push force. Then we created a cup and attached it to the arm where we will out our ammunition. When we attatched the arm we noticed that when we pulled the arm back to shoot it wouldn’t go very far since there was no force to pull the arm forward so when we put in would to far, so we added a rubber band to do the job. Finally we tested out our catapults and measured how far they went and who’s went the furthest.
I found this task fun because I enjoyed collaborating with my group and demonstrating the push and pull forces in a fun way.
