Agenda • Energy Unit • Works Stations • Pinning It! • Ramp Race • Energy of Motion • Simple Machines • The Ultimate Chain Reaction Recycling Machine * * * To be experienced today. 7/1/13
Energy activities * * conceptual development * To be experienced today.
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
