Here is a simple idea for an informative assessment: Rotate/Revolve Model Make this simple model to demonstrate the differences between rotation and revolution. Thread a practice golf ball onto a pipe cleaner. Twist the pipe cleaner closed, to make a loop. To show rotation: spin the ball. To show revolution: slide the ball around the pipe cleaner.
