KLACKERS
National Standard: B2
“... The motion of an object can be described by its position, direction of motion, and speed ...” 1
Suggested Use
Have students research Newton’s three laws, then use this simple machine to demonstrate! Hold the handle straight out with the two plastic spheres hanging down. Quickly move the handle up and down to get the “klackers” moving. (Related concepts: action-reaction, simple machines, inertia, etc.)
