we are well into our final science kit of the year. In this kit students are learning what it is like to have to design a vehicle to meet certain requirements. Each team has to work together and build a car to meet the challenge requirements using what they have learned from prevr experiments. We have learned so far that the weight of a vehicle effects how much force you need to apply to make the vehicle move. The heavier the load the more washers they had to use. Students are right now exploring how to use rubber band energy to make their vehicles move.
