The Angry Bird Project required 3 items Structure,Project tile and Prototype I was in charge Structure it was a small book case with a hole at the bottom are Prototype was a slingshot a small cart with 4 wheels as you can see below I learned about how it all comes together to be a fun project but also it taught me about force also the components are wood and elastic band, and we use ping pong balls when we pulled the elastic band back it collected alot of energy and all the energy balsted and cause the ping pong to fly and hit the target. My group had a fairly equal amount of job doing it was fun to because we thought it was hard but at the end we got it finshed and others who tested out of structure they liked it
