Today we used the Science and Engineering Practice of Asking Questions. The students first explored with marble roller coasters, and then came back together to think about what kinds of questions they could test with the marbles on the coasters. For example, they might want to know if they could change how far the marbles traveled on the coaster, or find out if one marble could knock another marble into the cup. Once they thought about the questions, they went back to their coasters to try to answer their questions by testing them out!
When the experiments were over, we talked about how the energy changed while the marbles rolled on the track, and also how the energy was transferred from one marble to another when they collided. Ask your student what happens to the kinetic energy of a rolling marble when it hits a marble that isn’t moving!
