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

Inspiration

Students build something like this….

Ramp B

Ramp A

Energy of Motion

- Quantitative
- Roll ball down ramps of different heights
- Model KE = ½ mv2

Simple Machines

- Find…
- Inspiration
- Techniques
- Get students to
start thinking

about how to

make

connections

The Ultimate Chain Reaction Recycling Machine

- Students analyze the energy transfers
