More Force and Motion
First graders have been investigating many things around the topic of force and motion. They have conducted experiments to find answers to various questions such as: How does a ball's size affect how it rolls down a ramp? How does a ball's bounciness affect its motion down a ramp? How does a ball's weight affect its motion down the ramp? How does the incline of the ramp affect how a ball rolls down it? How does the texture of the ramp affect how a ball rolls down it? Many of our experiments get at the concepts of gravity, friction and momentum. Students made very thoughtful predictions, carried out their experiments, and then recorded and wrote about their observations and conclusions.
