Rubber-Band Experiment

My little scientist, Abigail, has decided to do a rubberband car for her project this semester. She is learning about force and mass and potential energy (such as gravity when something is on a slope or suspended). I helped her build the car, and then she piled on different amounts of weight (washers) to see what the best ratio of mass to potential energy would be. She found the doubling the mass of the car worked best. Next project: redesign a Tesla .... !
