We often say food and fuels "contain" energy. It is more accurate to say that energy is stored in the "fuel-oxygen system" generated during photosynthesis. It is definitely "not" stored in fuels or food (except for the very small amount of energy that can be obtained during anaerobic respiration). Aerobic respiration…

We often say that food and fuels "contain" energy, whereas energy is stored in the fuel-oxygen system generated during photosynthesis. This article suggests revised approaches to teaching that make a clear distinction between matter (food, fuel, oxygen) and energy. (Contains 1 table, 5 boxes, and 6 figures.)

A survey of adults that shows considerable misunderstanding of two major ideas--that there is no energy in fuels and burning involves two stages--is discussed. Proposed are fundamental changes in the way ideas about burning are introduced to children. (KR)

Outlines a project in which the students calculate their family's energy budget. Presents efficiency guidelines for various appliances that convert to heat or kinetic energy. (GS)

Energy problems that incorporate power generation in hydroelectric, fossil-fuel burning, and nuclear power stations are presented. The burning process and the energy released are discussed. Practice problems and solutions, a summary of various energy units and conversion factors, and lists of thought-provoking energies and powers are included. (KR)

Provides background information and suggestions for concrete experiences to help nonscientists teaching 5- to 13-year-old children. Includes a list of 25 ideas for energy activities and a list of 10 key energy concepts. (JM)
