Describes a chemistry experiment appropriate for the day before Christmas vacation. Students prepare candy canes by following a recipe written in chemical terms. This illustrates that food is composed of chemicals and that the processes involved in cooking are chemical and physical changes. (JR)

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)

Applications of wheels are shown to be an invaluable tool in teaching the processes and technology of science. (DF)

Presents a series of investigations focusing on the biodegradable packing materials ("peanuts"), which provide a method for exploring science through experimentation. These activities can help fourth through sixth graders sharpen their critical thinking and science process skills. (PR)

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

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

Discusses the educational values of participating in science fairs, and outlines the procedure used at Saint Ursula Academy, Toledo, to interest each biology student in an individual investigation. (JR)

Describes a lab investigation designed to introduce students to soil compaction and help them to learn to design and adapt procedures that scientists use when they plan and conduct controlled investigations. Provided are objectives, a list of materials, procedures, and a sample student handout. (CW)

Describes activities with organisms from freshwater ponds and ditches. Several experiments involve predation, some involve habitat choices, and one addressees the role of sunlight in supporting plant-eating animals. (PR)

Describes a demonstration to show the character and behavior of mixing clouds. Discusses laminar and turbulent flow, and the formation of contrails and other cloud phenomena. (CW)

A joint business-chemistry course which focuses on consumer testing is described. Guidelines for organizing the students into testing teams and suggested laboratory experiments are included. (DT)

Describes simple-to-construct instructional aids to be used in providing an intuitive approach to acceleration. Introductory mechanics involving velocity, distance and acceleration are discussed. (CP)
