Students doing a physics experiment

Existing theory asserts that momentum is conserved. In this lab, High
School Physics students will explore qualitatively and quantitatively
the conservation of momentum in an inelastic collision.. They  will
calculate the momentum before a collision and the momentum after a
collision between two small marbles. As an extension they will then
design their own labs to further test this theory under their own
conditions. As a class we will then establish our own set of rules to
explain the results using Newton's Laws as a guideline.
