Students make a small moving contraption out of cheap materials and then perform a quick energy transformation experiment with it. Middle school students really enjoy this NGSS activity! Includes simple materials list, directions, data table, and analysis questions. The activity highlights that the amount of potential energy you start with is directly related to the kinetic energy you end with. Also supports MA 7.MS-PS3-7.
Materials: wooden or plastic thread spool (only $5 for 42 spools on Amazon), rubber band, paper clip or toothpick, small wooden dowel (or broken pencil segments)
