Hydropower !. Rowan University Freshman Clinic Fall 2003. Objectives of Module. Learn about energy conversion Learn about unit conversions Understand the differences between force, work, and power Assemble a turbine, measure dimensions Document the tests neatly in your lab books

Applications of Energy to The Real World. A TAKS Tutorial. Energy causes Change. The sun radiates light and heat energy. At night, street lights convert electrical energy to light. As a car drives by, it is making power from gasoline - stored energy.

Conservation of Energy. Lesson Objectives: All must know that energy an be neither created nor destroyed but it can be changed from one form into another. All must know that some energy is wasted (usually as heat) when energy is transferred.
