Five objects of various size, weight and composition to act as simulated meteors. A device for dropping objects. The easiest method is to drop objects by hand. However, the height of the drop must be measured carefully. A balance for measuring the mass and weight of the objects.
Students working in groups drop their objects one at a time from different heights.
Record the length, width, depth and distance of ejecta from the crater rim for each simulated meteor and enter on a recording sheet. Debrief the results. Each group explains in written and oral form the results of their experiments . Extensions As a grand finale for your students, demonstrate a more forceful impact using a slingshot. Pans should be plastic, aluminum or cardboard.
