Described is a physics experiment which investigates the reactions occurring when a hot dog is fried or broiled. (SL)

Understanding students' challenges about using microcomputer based laboratories (MBLs) would provide important data in understanding the appropriateness of using MBLs in high school chemistry laboratories. Identifying students' concerns about this technology will in part help educators identify the obstacles to science learning when using this…

The Space Shuttle and International Space Station provide a unique microgravity environment for research that is a critical part of the National Aeronautics and Space Administration's (NASA) mission to improve the quality of life on Earth and enable the health and safety of space explorers for long duration missions beyond our solar system. This…

This book represents a "cookbook" for teachers of physics, a book of recipes for the preparation of demonstration experiments to illustrate the principles that make the subject of physics so fascinating. Illustrations and explanations of each demonstration are done in an easy-to-understand format. Each can be adapted to be used as a demonstration…

This teacher's edition of "A Manual of Experiments in Elementary Science" includes full directions and explanations regarding all manipulation, answers to all the questions in the "Student's Manual," diagrams, and additional hints and suggestions. The work covers elementary science experiment outlines adapted for use with…

Describes several well documented cases of Extra Sensory Perception (ESP), and discusses ways in which ESP experiments can be conducted in the science classroom to investigate telepathy, pyschokinesis, and clairvoyance. (JR)

Discusses five experimental methods used by senior high school students to provide an accurate calibration curve of magnet current against the magnetic flux density produced by an electromagnet. Compares the relative merits of the five methods, both as measurements and from an educational viewpoint. (JR)

Briefly outlines the theoretical basis of the phenomenon of photoconductivity and describes a simple experiment which demonstrates the photoconductive properties of cadmium sulfide. (JR)

Discusses Einstein's views on the role of Michelson-Morley, Fizeau, and Miller experiments in the development of relativity and his attitude toward the theories of new quantum mechanics. Indicates that Einstein's opposition to quantum mechanics is beyond dispute. (CC)

Describes a few activities designed to give students an opportunity to investigate man-made meteorites.'' (Author/DF)

Using syringes, a hydraulic press was constructed and mechanical advantage and efficiency were calculated. (CP)
