IMPACT CRATERS
Student Name: _________________________________________________________
Partner(s) Name(s): _____________________________________________________
Goal: Determine the relationship between the size of an impactor and the size of a crater.
Note:
1) When measuring diameters, measure it twice: 1) along the major axis, 2) minor axis.
2) Smooth the sand surface with an edge after each trial.
3) Position the meter stick on the edge of the tray.
