This lab is an inquiry activity to be used before discussing inertia. Out of necessity to explain the observation, a short discussion of inertia is included, but teachers should certainly spend more time making this…

This lab introduces students to the idea of recoil and how conservation of momentum can be used to explain it. Many people use action/reaction to explain recoil, but conservation of momentum can be used equally well.…

This inquiry activity should be performed after students have learned about momentum, but before they learn about conservation of momentum. Students will discover that when two objects push off each other, the momentum…
