Technical Notes

Make sure you have permission to make mud (and noise outside!), a method to clean up and keep track of spherical objects (marbles, bb's, flat basketball or volleyball or soccer ball), a camera is helpful unless you are having the students sketch their craters and cooperation of rules (cannot throw objects at each other or windows, only drop!)

Learning Objectives

Students will create their own craters, in mud that has been layered with flour and paprika (to show striations in the ejecta), to help draw conclusions on the speed and size of the objuects which could have created impact craters on the moon.
