Hybrid Car
For our hybrid car project, we had to design a car that would go exactly 5 meters carrying a 250 gram mass. For our car, we used rubber bands. We used CD's and card board for wheels. The body of the car is card board and wood. Our car was very successful and stopped at exactly at 5 meters almost every time. The key was to make it light weight and fast. Our car only weighed 100 grams and went 5 meters in an average of 3.5 seconds. Over all, our car was very efficient.

Reflection
Our car was very efficient. It went 5 meters almost every time. The best part of our car was probably that it was fast, light weight, and could hold over 1000 grams. We didn't have trouble with time management. We had trouble trying to choose an idea for our car. We started with a rat trap car. It didn't work to well so we tried a rubber band car. We built it very fast and finished with two days to spare. If I could do something differently, I wound research the best way possible and then start with the rubber band car instead of starting over and making two. But other than that, our car worked great.
