Several suggestions are made for using empty duplicating fluid containers in science experiments and activities. (JR)

Describes methods and procedures for killing, preserving, mounting, and displaying insects. (JR)

Several simple experiments using easily obtained materials are described which illustrate some of the properties of light (travels in straight lines, reflection, and refraction). (JR)

Directions are given for the construction of a manometer to measure animal metabolism. Steps in an experiment to measure frog metabolism are specified. (DT)

Explains the teaching opportunities, especially in science activities and laboratory experiments, of using technology in science classrooms. (YDS)

Describes a number of experiments which give the student an opportunity to observe the effects of the electrical nature of matter without trying to explain why a given phenomenon is occurring. These experiments should be introduced before discussing the structure of atoms, and provide practical experience for later theoretical discussions. (JR)

Twelve science activities involving the common paper food bag and the small plastic food bag are described. (DT)

Describes eighteen ways in which balloons may be used as a teaching tool in demonstrations and discovery exercises in science. (JR)

Describes an activity using simple materials that gives students an opportunity to express their ideas about possible extraterrestrial life forms. (JR)
