  1. 1. Emily is riding her bicycle. Which BEST explains why only some of the energy used to pedal her bicycle is transferred into forward motion of the bicycle?

  2. 2. A wind generator transfers wind energy into electrical current. How does the amount of energy in the electrical current compare to the amount of wind energy that turns the blades on the wind generator?

  5. For each device, students should identify and explain the energy transformations that occur. Teacher Note: Ideally, the students will have the opportunity to explore physical examples the energy transformations. Alternative transformations may be substituted based on local supplies/materials. Explain the Energy transformation
