Describes a unit of study in environmental education which utilizes multimedia techniques to assist the student in making and evaluating predictions about the future of "spaceship earth." (JR)

Describes a field-biology research project conducted at Coos Bay, Oregon by high school students attending the summer sessions at Terramar Field Science Facility during the summer of 1972. Discusses the value of this type of environmental survey for both the students and the community. (JR)

Discusses the use of aluminum chloride and other Friedel-Crafts type catalysts to polymerize 2-methylpropene and the application of such products in industry and agriculture. Includes a laboratory experiment on the polybutene preparation suitable for high school purposes. (CC)

Discusses application of Schoniger's method of quantitative organic elemental analysis in teaching of qualitative analysis of the halogens, nitrogen, sulphur, and phosphorus. Indicates that the oxygen flask method is safe and suitable for both high school and college courses because of simple apparatus requirements. (CC)

Describes a number of activities and experiments designed to add interest and increase understanding in the secondary school physics laboratory. (JR)

Describes an elementary school science activity in which students conduct experiments to verify their hypotheses relating to the effect of salt and other chemicals on the melting point on ice. (JR)

Describes an experiment, conducted by sixth-grade students, with mice that demonstrates the importance of a balanced diet. (JR)

Describes how to construct a locust cage from two plastic aquaria and four coffee jars with plastic lids. Its advantages over a conventional locust cage include the inexpensive cost, lack of breakable glass, ease of cleaning, and visibility from all angles. (JR)

Describes an activity designed to stimulate elementary and junior high students to become actively engaged in thinking creatively rather than only analytically, convergently, or repetitively. The activity requires students to devise means of dropping an egg from a height without it breaking. (JR)

Discusses the importance of the tactile sense in the learning process of young children. Describes a program in which children are able to handle natural history objects provided by a museum. (JR)
