Summary:
Today students completed the friction lab, a little experiment that explores how friction affects a rolling marble. The lab asks students to compare four surfaces (a table top, printer paper, wax paper, and sandpaper) and compare the amount of friction created by each. Students calculate the average distance that the marble rolls. And they repeat the experiment with a metal and plastic marble to investigate how the mass of an object can change the amount of friction.
