Solar Energy, Second Edition

The assignment: harness the energy of the Sun to power a motor and purify water.
First students discover the concept of energy transfer from a source (the Sun) to a receiver (solar collector). Then, in a series of heat exchange experiments, they test the variables that affect energy retention: covers, colors, water levels, exposure times, angles of presentation, types of solution, and uses of reflectors. They also convert solar to electrical energy and control the speed of their solar-powered motors. In other activities, teams investigate insulation and build an apparatus that distills water.
