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)
