Physics.
The reason for why I chose my mousetrap car for refinement is because , in my opinion, this is the project that needed the most refinements done to it. Also, this was our second car. We, me, Melanye, and Nate, worked very hard to make this better than our last cars and for it to be able to go up a ramp, which we did at our exhibition. our car didn't end up winning but we didn't get last so that was okay. We tried our best and that's all that mattered to us.
Below are other projects that I've completed and am proud of this year.
