Energy Transformation


How can energy that is expended to do one thing, power a machine to do something different?


  • Can You Power A House With A Bicycle? video
  • Computer with Internet access for research
  • Color printer     
  • Digital camera     
  • Typical office/hobby/hardware/craft supplies (paper, poster board, glue, etc.)     
  • Whatever supplies are needed if you decide to build your design.


  1. Watch the Can You Power A House With A Bicycle? video, or something similar, to gather ideas about how energy works to power machines.
  2. Design a contraption that does useful work using motion generated by something that is already using energy, like someone walking or riding a bike.
  3. If possible, build your design and see if it works.
  4. Interpret your findings in a detailed report.
  5. Include photos, diagrams, models, and demonstrations in your science fair display.
