Students can put two to three inches of the lighter colored powder in the pan and then a sparse layer of the darker color on top. This will help them see where the powder goes when the object hits. The fork can be used to smooth the surface out after each "meteor".
Have the students drop each object into the tray twice and measure the depth and diameter of the crater. If they get very different answers for an object, they should measure it a third time. They should experiment with dropping the same object from different heights and with different amount of force.
They can use the worksheet to record their results.
