Demo Title:
Area of Study:
Solar System
Rotating Platform, Light Source, Rock Asteroids, Painted Rock Asteroids, Aluminum Foil Ball Asteroid, Plaster of Paris Asteroids, Light Sensor with Interface, and Computer.

Place the desired "asteroid" onto the rotating platform and secure with some modeling clay if needed.  Positon the light sensor and the light source so that they are pointing in the same directiion onto the asteroid.  Note the light curves for each different kind of "asteroid" as the platform is rotated.
