1. Describe how you contributed to your team, what did you do, were their any major contributions you are especially proud of?
I helped my team by contributing possible ideas and help them to test out possibilities. I can’t say I had some major contributions since I only helped and offered ideas to revise the prototype.
2. Did your team apply the EDP successfully? (i.e. did you identify the problem & constraints, brainstorm solutions, test and prototype a solution, refine the design).
Yes we did. At first we did some brainstorming and then we talked about those solutions. We even drew some drafts of the prototype. We made a prototype first and then made changes to it. So I think we applied the EDP quite successfully.

3. What changes did your team make to your design?
In our first design, we had this horizontal stick on the prototype to prevent the vertical and spinning stick from falling. But then, we took it off.
4. what worked well in your design? Identify what did not work so good.
Our group’s design looks really weird, because it was base on a triangle, however, it worked pretty well. However, like I mentioned in question 3, the horizontal stick didn’t work well, because it only prevented the spinning stick from falling, it also stopped it from spinning.
5. Describe any energy conversions/forces/motions/Newton’s laws that apply to a catapult mechanism.
The rubber band converted the elastic energy into the kinetic energy, and when it was released, it created forces to let the stick throw out things. The sticks have gravitational potential energy, and it converted into the kinetic energy. Also, the catapult applied the Newton’s first law of motion. Because when the rubber band was released, the stick contains inertia, and it just throw itself forward.
