work stations
Work Stations
  • Qualitative
  • Students rotate around stations
    • Observe
    • Explain
    • Guess at what work is
  • W = F∆x
pinning it
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
Ramp Race
  • Quantitative
  • Roll marble from same height but differently sloped paths
  • ∆PE = ∆KE

Inspiration

Students build something like this….

Ramp B

Ramp A

energy of motion
Energy of Motion
  • Quantitative
  • Roll ball down ramps of different heights
    • Model KE = ½ mv2
simple machines
Simple Machines
  • Find…
    • Inspiration
    • Techniques
    • Get students to

start thinking

about how to

make

connections
