LaHart, David, Ed. – 1981
Fossil fuels, upon which we now depend almost exclusively, are finite resources. Because the environmental problems inherent in large scale fossil fuel consumption are increasingly apparent, the reality of developing alternative energy sources must be faced. Solar energy is the obvious solution to the problem. It is a renewable, clean source that…

Tinnesand, Michael; Chan, Alan – Science Teacher, 1987
Argues that cookbook chemistry laboratory experiments do little to teach scientific inquiry. Suggests providing students with laboratory experiences that follow the introduction of a concept and challenge students to investigate that concept through an experiment involving very few initial instructions. Lists some such challenges used in chemistry…

Gilbert, George L., Ed. – Journal of Chemical Education, 1987
Describes two laboratory demonstrations in chemistry. One uses dry ice, freon, and freezer bags to demonstrate volume changes, vapor-liquid equilibrium, a simulation of a rain forest, and vaporization. The other uses the clock reaction technique to illustrate fast reactions and kinetic problems in releasing carbon dioxide during respiration. (TW)
