Twelve ideas are presented for physics teachers to implement in the laboratory or classroom. Topics covered include electromagnetic induction, microbalance, capacitors, determination of light velocity, and the compound pendulum. Information regarding laboratory equipment is also provided. (PS)

Describes techniques and results of a study on leaves of a leguminous tree. (PS)

Describes an experiment which can be used to provide an introduction to study of reaction mechanisms and training in use of simple analytical and instrumental techniques. (PS)

Six new experiments are described for use in elementary school classrooms. Phenomena explored include friction, mass of air, kinetic energy, air condensers, and hot-air balloons. Instructions are explicit. (PS)

The concept of energy consumption can be learned by role playing, using jelly beans as units of energy with children as primary, secondary, and tertiary consumers. Follow-up questions are suggested for further discussion. (PS)
