OK Go video for demonstrating energy transfer

Many of the sciences discuss energy transfer and energy loss.
  • Biology: Sun --> plants --> herbivores --> carnivores, etc.
  • Physical Science: solar --> chemical --> mechanical, etc.
  • Physics: potential, friction, etc.
  • Chemistry: (less so here, but) energy can be harnessed from one reaction to start another
OK Go put out a video last spring that I used and the students seemed to enjoy: This Too Shall Pass (Rube Goldberg Version).

Questions to ask:
  1. How is this relevant to what we're learning?
  2. Explain how energy moves from one to another.
  3. The energy seems endless, doesn't it? Where did all this energy come from? Could it happen again if you went back to the beginning and hit that domino with your truck?
