Describes the life cycle and control of the greenhouse whitefly. Explains the culture of the whitefly for school use and presents a list of laboratory exercises that can be done in a double period. (GS)

Describes laboratory procedures for culturing drosophila and for observing their behavior. Outlines drosophila response to stimuli and explains the courtship sequence. (GS)

Uses a printed sheet of paper to represent a plant population in a given area. Quadrat sampling is simulated by dropping a square coverslip on the sheet and recording the symbols under the coverslip. Line-transect method is simulated by having a student randomly adjust the sheet under a string. (GS)

Suggests taking physics to a playground to manipulate the apparatus and to examine the equipment; applying physical principles such as the pendulum model to swings and angular momentum to the merry-go-round. (BR)

Describes two methods for the direct observation of soil-dwelling micro-organisms. One method is for relatively dry habitats and the second, for permanently wet habitats. (GS)

Describes an approach which emphasizes the physical aspects of periodic phenomena, and is explicit about whether the time or space domain is being treated. (Author/GS)

Illustrates a safe and easy way of igniting a hydrogen-oxygen mixture and lists the equipment used. (BR)

Describes some specific activities to be used on the first day of science class to demonstrate science as a process and to allow students the use of inquiry skills in problem solving. (BR)

Describes some "openers" to use in science class to attract attention, create interest or maintain interest. Some examples of materials that can be used are a radiometer, a drinking bird, Geiger-Muller Counter and a human skeleton. (BR)
