Enjoy our final our engineering project! We made roller coasters for ping pong balls. Each team had to come up with a design plan when given a certain set of materials and criteria. If their original plan didn’t work or if they thought they could make it better then they need to go back and change their plan and model to have a better product. Here are their final products. 🙂
