Presents the results of an experiment designed to test two hypotheses: (1) a delay of two weeks at room temperature will have no effect on the viability of fertile chicken eggs and (2) refrigeration will have no effect on the viability of fertile chicken eggs. Experimenters were the author and two ninth-grade students. (PEB)

Examines the phenomenon of water drops that float on water at room temperature. Describes experiments that have been done to study this phenomenon. (MA)

Two physics experiments are described, One, involving a laboratory cart accelerated along a level surface, examines the concept of inertial mass in translation and the other, using a solid cylinder, measures the moment of inertia of a wheel. Equations and illustrations are included. (MA)

Describes an experiment on Doppler effects using air cars on a linear air track and a homodyne Doppler radar system. (SL)

Reviews various science activities investigating polarized light. (SL)

Describes an apparatus for an experiment on winding motion in three dimensions. Discusses theory and provides a calculation example. (JM)

This book presents 65 simple, safe, and intriguing hands-on science activities. In doing these simple experiments, children can make a variety of discoveries that will surprise them. It includes many activities from discovering how people see color and what makes people's hair stand on end, to creating a tornado in a jar or a propeller-driven boat…

A way of teaching the scientific method to elementary pupils, using animal life collected by students. (SP)

Discusses a course, centered around 32 experiments taught for advanced students, designed to develop a laboratory strongly suggestive of contemporary research using relatively sophisticated apparatus. Its unique advantage lies in enriching advanced physics curriculum. (DF)

A multidiscovery, open-ended, sciencing experience appears to have implemented nearly the full spectrum of cognitive, affective, and psychomotor objective domains.'' (Author/DF)

Describes the use of laboratory equipment to demonstrate (1) the interference of light coming from an air wedge, (2) the generation of gas-filled soap bubbles, and (3) the generation of beats with a ripple tank. (LC)
