In this lab, students explore the connection between the mass of an object, and the object's kinetic energy. I used ramps and Hall's Carriages for this, but toy cars can be supplemented if the carriages are not available. The lab includes all steps of the scientific method, along with a full rubric to assess students' learning. All you need to do is gather the materials.
