IIA. HOW ARE CRATERS MADE?

Concepts:

Impact craters are made when an object or bolide impacts the surface of a planet or satellite. A bolide is any falling body such as a comet or meteorite. Many hands on impact simulation activities are available, and all involve dropping a series of bolides, with different masses, onto a simulated planetary surface. The planetary surface can be dry, for example made out of flour with a dusting of cocoa powder, or wet, such as a muddy composite of dirt or sand.

[A variety of cratering exercises are available. See Craters! ]
