In order to deal with these facts, science educators are beginning to reevaluate energy programs. Traditional energy studies have focused on fossil fuels; in particular, oil, coal, and natural gas. Many educators now realize this approach is very short-sighted. An alternative energy project can introduce the important concept of the finite nature of energy and natural resources.
This unit on solar greenhouses meets the following objectives. As an alternative energy project, it: 1) encourages the study inter-disciplinary subject matter; 2) increases knowledge of small scale technology; 3) stresses the use of a renewable energy source, conservation of energy, and food production; and 4) provides the schools with a socially responsible demonstration project. At the same time, vocational students can be involved with the actual construction of the building. Horticultural students can learn about plant life and food production. Science students can experiment with energy concepts.
The Solar Greenhouse Unit is designed for middle and high school students. It can be included in studies on alternative energy or solar architecture. The material can be used in a flexible manner, depending on teacher needs. The unit can last from one week to four weeks.
