At first I had trouble thinking of what to do, but then after watching videos of other students I finally came up with an idea. The biggest challenge was making it successful. Also it was hard to find a way to use 3 simple machines. We had an inclined plane, lever and wheel and axle. Our wheel and axle was a toy car but while we were testing it before we videoed it, it wouldn’t work so we used a battery instead. what was was very frustrating is that my mom didn’t video the first success which was very upsetting because it took us a long time to do it after.
