"Our problem is Lunch can get hot in the sun and we invented a lid that can cool it down. I built a fan to keep lunch cool at school. And we also built a tarp for the lunch wagon. The motor broke but we fixed it. We had a metal Strip connected to the battery and the motor And the blade did spin now we have a working fan. We did 3 different prototypes to get our invention to work. "

  1. Great project! I really enjoyed reading about your different prototypes and how you made improvements on each one. Your slides that show what you did, your results and a photo made it very easy to follow and understand what you did. I also liked that you received feedback from your classmates – what a great way to help out your class!
