Get yourself a metal sled that runs on tiny plastic ball bearings, and you'll be ready to demonstrate to your classroom Isaac Newton's third law of motion: Every action has an equal and opposite reaction.
This science video tutorial will teach your students how Newton's third law of motion works, with a metal sled that slides real easily. Get a rubber band and some scissors and get ready for a great example of this motion law.
