Everything You Ever Wanted to Know about Newton!
If you have stopped in Whistle Stop Books or the Cambria Toy Station in the last few years, there is a good chance you stopped for a minute and played with the Newton’s Cradle, a desk toy named after Sir Isaac Newton and based on one of the key principles of Newtonian physics. The “toy” illustrates the laws of inertia (Newton’s 1st Law of Motion), conservation / F=ma (force=mass * acceleration-Newton’s Second Law of Motion), and Newton’s Third Law of Motion: “for every action, there is an equal and opposite reaction.”
Want to know more about Newton’s Cradles? (None of which are appropriate for the average elementary student–above their pay grade, but interesting reading if you want to know more before you talk to the said same six or eight year old)…

Pick a couple of projects from the Harvard Natural Sciences Lecture Demonstrations Collection. A great collection of science projects and experiments for home and science fairs…some very cool stuff. Start with Newtonian Mechanics.
Build your own Newton’s Cradle from Scratch (Compliments of the folks at Cornell). If you want to do Newton’s Cradle experiments, but you don’t want to go to the trouble of making one, swing by the Cambria Toy Station and pick up a Newton’s Cradle of your own.
