During this 3-4 day project, students will be designing and building a Marble Track to better understand the arrangement of object interacting at a distance and how kinetic and potential energy changes when distance (from the ground or from the end of the track, etc.) changes. Standards Covered...MS-PS3-2 Develop a model to describe that when the arrangement of objects interacting at a distance changes, that different amounts of potential energy in the system. PS3.A Definitions of Energy (Potent
