Present a Wide Variety of Standard Force and Motion Activities.

Educators can conduct a comprehensive array of density experiments with the density/slope class set.

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

These large alloy tuning forks are designed to demonstrate resonance, beat frequency, and sympathetic vibration.

Electrostatic charges are indicated by the deflection of a black plastic straw pivoted on a pin. The polished zinc plate on top is used to demonstrate photoelectric effect and various other electrostatic demonstrations. The metal case measures 14 cm in diameter. The scale is graduated in 10° increments in two quadrants.

This ripple tank is transparent, acrylic plastic and supported in a sturdy plastic frame.

These long-lasting aluminum tuning forks have a full sound.

A mess proof way to demonstrate waves and refraction in water.

A simple tool for communicating complex workings of electricity, this plastic battery holder is fitted with three banana plug jacks.

The demonstrations feature the fundamentals of vacuum and air pressure as they describe how a pump works and how to find the mass and density of an air sample.

Grab and hold students' attention with these interactive and affordable demonstrations that show core physics concepts in action.

Perfect for density experiments, use this set determine the mass and volume of each sample and graph the mass versus volume. The slope of the straight line that results is the density of the material.

The Precision Linear Expansion Apparatus produces accurate determinations of the coefficient of expansion.
