Why Lesson Planet?
The first activity may not work for your class if you don't have access to an open area of 30 meters and two cars of different masses, but the remaining activities can be used in any physics course. They all involve the investigation of Newton's first law of motion. If you visit the Scope, Sequence, and Coordination of Secondary School Science website by the National Science Teachers Association, you will easily find the student handouts. In addition to procedures for the activites, this resourece provides 18 different assessment exercises for you to choose from!
