Provides a technique for the determination of the mass of a large, movable object. (CP)

Describes a group of chemistry experiments designed to convey to students the real and measurable nature of certain mathematical concepts. (BR)

Describes a demonstration with mothballs that simulates the ballast mechanism of a fish air bladder. (BR)

The different approaches to the generation of power from solar energy may be roughly divided into five categories: distributed collectors; central receivers; biomass; ocean thermal energy conversion; and photovoltaic devices. The first approach (distributed collectors) is the subject of this module. The material presented is designed to…

The purposes of water treatment in a marine steam power plant are to prevent damage to boilers, steam-operated equipment, and steam and condensate lives, and to keep all equipment operating at the highest level of efficiency. This laboratory exercise is designed to provide students with experiences in making accurate boiler water tests and to…

Describes a physics laboratory experiment for nonscience majors intended to illustrate indirect experimental methods of sciences treating objects too small for sensory observation. The student explores and attempts to identify an object in a closed container, using provided experimental tools and small openings in the opaque lid. (MLH)

The study was designed to determine how standard science skill builder activities can be modified or adapted for use by orthopedically handicapped students. Nine secondary level science experiments were selected for initial review and from these, three were selected for adaptation--use of the microscope, use of graduated cylinders, and use of the…

AN ATTEMPT WAS MADE TO ASCERTAIN WHETHER MOTION PICTURE FILMS OF SELECTED PHYSICS DEMONSTRATION EXPERIMENTS WERE AS EFFECTIVE AS DEMONSTRATIONS PERFORMED DURING COLLEGE PHYSICS LECTURES. A SECOND OBJECTIVE WAS TO DETERMINE WHETHER STUDENTS WOULD TAKE ADVANTAGE OF THE OPPORTUNITY TO VIEW SOME EXPERIMENTS ON FILM OUTSIDE OF CLASS ON A VOLUNTARY…

Nine experiments and 17 activities are presented in this handbook. The experiments are related to the earth's size and orbit, Piton height, telescope operations, Mars and Mercury orbits, stepwise approximation, and models of comet orbits. Further naked-eye observations in astronomy are designed in connection with the sun, moon, and planet…

This booklet was written for students as a source of ideas for research type science projects. Part One shows how three high school students developed individual projects a s a result of asking questions about the same natural phenomena. Part Two contains project suggestions and sample questions designed to stimulate student thinking along…
