A unique and inexpensive kit that covers the history of solar heating and lets you experiment to improve heating efficiency. A gravity-fed water system through a solar collector is used to test and record data on heating capabilities. The lessons allow you to determine heating potentials, background reflection-absorption abilities, adaptabilities to commercial use, and current methods of solar heating. -- This kit offers better learning experiences than units costing several times as much. -- Includes: collector, student study sheets and a detailed teachers manual. |
