Crucial physics / key math

Seed with a brief review of the crucial physics learned, and the skills students should demonstrate in problem-solving.

This is the first time that students explore equal and opposite forces.  You will need a tool to help students "see" the force from the wall or other objects.  Using spring scales and floor scales is a start.  Ask students to journal on their observations and then share what they wrote.  The misconceptions will show up in many ways.
