Explains how to use sticky tape, a soda straw, and a little water to build a device which will demonstrate Charles' law as well as give the temperature. (GA)

Explains how to demonstrate the fundamentals of one dimensional kinematics such as Newton's third law of motion, and collision between bodies, using simple materials of marbles, strings, sticky tape, drinking straws, and rubber bands. (GA)

Describes an experiment on heat that utilizes only a styrofoam cup of coffee and a soda straw thermometer. (BT)

Describes a simple method of measuring the refractive index of a liquid using a paper cup, a liquid, a pencil, and a ruler. Uses the ratio between the actual depth and the apparent depth of the cup to calculate the refractive index. (GA)

Presented is a simple demonstration of siphon action by using straws without sucking, or filling and closing one end. Includes the method, figures of the demonstration, and four questions for students on the demonstration. (YP)

Describes experiments, including the measurement of the magnetic moment of a magnet, using noncalibrated materials. Results of these experiments can be checked using calibrated equipment. (SK)

Describes a demonstration of light pipes using low-cost materials, relating it to fiber optics communication. Also provides several experiments in hydrostatics and hydrodynamics using the materials for light pipe. (JM)

Several activities focusing on the elasticity of rubber bands and chalk are described. Explanations for the observations noted are included. (JN)

Described is an experiment for measuring the coefficient of restitution with a meter stick, balls of different types, and scraps of material for the plates. Provides the experimental procedure and an apparatus diagram. (YP)

Demonstrates the inverted image, the chromatic aberration, and the floaters of the eye using an opaque 35mm film container with a small pinhole poked through the bottom. Describes the observation of Haidinger's brushes using polarized light. (YP)

Describes making a cardboard frog. Discusses the physics of various motions of the frog. Provides diagrams showing how to make the frog, the motions, and the mechanics formulas. (YP)

Experiments which illustrate the effect of humidity on human hair and on paper are described. Also described are two ways to make a hygrometer. These methods were found in a series of British television programs (also available in the United States). Comments on the programs are included. (JN)

A simple device used to demonstrate the main features of primary color addition is described. Materials needed to construct the device, procedures used, and typical results are discussed. (JN)

Describes how to make an electroscope from aluminum soft drink or beer cans. Also describes several electrostatic experiments using the easily constructed apparatus. (JN)

Describes two simple physics experiments demonstrating the spin on baseballs or golfballs and the observed effects of falling coins when released together. (CS)
