Today what worked for us was the car I mentioned before, that had a wheel on top of it so if it fell it would keep going. However, what didn't work for us was when we tried to modify it to make it lighter. After modifying it to make it lighter and realizing that didn't work, we rebuilt most of our original car before the end of class.

What happened when you tried to make it lighter? By the way I really liked your idea of the wheel for falling. It seems like a good safety insurance. Also how did you modify it?

What made the car lighter, taking the wheel off from the top of taking other parts off? I think it's a really interesting and unique idea to add a wheel to the top of the car!

Thanks! And when we tried to make it lighter, it didn't work as well. Also when it fell over, it didn't have the extra wheel to keep going. How we modified it was that Andrea was able to stay after school to add a few parts to it to make it better.
