Work Stations  Qualitative  Students rotate around stations  Observe  Explain  Guess at what work is  W = F∆x

Pinning It!  Engage and Explore  Qualitative  Drive a pin into wood by dropping balls on it  Could be Nailing It! if you have bowling balls  PE = mgh ∆PE = W

Ramp Race  Quantitative  Roll marble from same height but differently sloped paths  ∆PE = ∆KE Ramp A Ramp B

Energy of Motion  Quantitative  Roll ball down ramps of different heights  Model KE = ½ mv 2
