Directions are given for the construction of mazes suitable for use in the classroom. The animal maze may be used to investigate small animal behavior, and the finger maze provides students with the opportunity to experience similar frustrations to those encountered by animals in the network of passages. (JR)

Discusses the principles, construction, and operation of an apparatus which serves to demonstrate the non-colinearity of the angular velocity and momentum vectors as well as the inertial tensors. Applications of the apparatus to teaching of advanced undergraduate mechanics courses are recommended. (CC)

Discusses the construction of a diffractometer table and four microwave models which are built of styrofoam balls with implanted metallic reflecting spheres and designed to simulate the structures of carbon (graphite structure), sodium chloride, tin oxide, and palladium oxide. Included are samples of Bragg patterns and computer-analysis results.…

Discusses the use of a modified air table to conduct laboratory experiments which eschews research-oriented lab experience and concentrates on concepts learned in classroom. Includes a description of apparatus construction, sample instruction sheets, and a list of laboratory concepts with their relationships to classroom materials. (CC)

Includes eleven topics relating to laboratory activities, experimental procedures, and teaching materials suitable for secondary school chemistry classes. (JR)

Describes and includes the plans for an exhaust and plumbing system for small engine dynamometer and outboard test tank. (GR)
