1. Given the challenge and the performance of your car on Test Drive #1, what change(s) did you make for Test Drive #2? I started to think simpler, and I started to come up with an idea, and then my partner understood what I was thinking/saying, and we built it.
2. What differences did you predict these changes would make in your cars performance? What makes you think this? We actually started over. And we predicted that it would kind of be like how  they launch each other in Angry Birds.
3. Think about the variables such as the size of the spool, weight of the washer or tension of the rubber band. How might these affect how far or how fast your car will go? If the weight of the spool is higher, then the when you launch it, the spool won’t go as far.
4. What worked better the second time? WE GOT SECOND PLACE!!!!! And it actually worked.
5. What still is not quite working? Well we didn’t put as many rubber bands on as I wanted to which means it didn’t go as far as I wanted to, but after for pleasure, I put A LOT more on, and… IT WENT SUPER FAR!!!!!!!!!!
6. What are some questions you have? Do aerodynamics affect ground vehicles? What are other ways to make it go far and fast?
7. What might I try next? Adding the answers of these questions into the product.
8. Explain the energy transfer that is taking place in the racer. When we pull back the car, it’s stretching out the rubber band. Which creates elastic energy, and then when you let go of it, it launches it, and then it converts to kinetic energy.
