Thames and Kosmos Alternative Energy and Environmental Science Power House Green Essentials
Power House:  Green Essentials Edition.  To live sustainably, we must use Earth's resources at a rate at which they can be replenished, and thus provide for future generations to live as we have.  In this kit, you can learn about alternatitive energy and sustainable living by conducting experiments and building energy-related models.  Thirty of the best experiments and the ten most important building projects from the original Power House kit are presented in their Green Essentials Edition.  The ten building projects include:  the power house itself, a greenhouse, a solar cell array, a passive solar collector, a solar oven, an air conditioner, a refrigerator, a hydrometer, a lemon battery, and a wind power generator.  Experiment with the heating, cooling, and insulation of the house and greenhouse.  Test passive solar collection methods with a solar collector.  Assemble a solar power array to explore active solar power with photovoltaic's.  Build a model refrigerator and air conditioner to learn about heat transfer.  Experiment with a lemon battery to learn about power storage.  Set up a wind turbine to generate electricity from the wind.  As you perform the experiments, you will read the diary entries of a group of young explorers who are learning to live a sustainable existence on an island.  To survive, they must implement real-world versions of the projects you are doing in the kit.
