Impact craters are formed when impactors such as meteorites smash into the moon's surface. The factors affecting the appearance of impact craters include the size and velocity of the impactor and the geology of the surface. Students will use flour, baking soda and cornmeal to recreate a lunar surface. They will then drop impactors such as marbles onto their lunar surface from various heights. Finally, they will measure various characteristics of the impact craters formed.
