"Paleontology Models"

Determine the speed of sound in air by investigating the resonance of a column of air.

Measure the acceleration due to gravity three different ways.

Analyze the displacement of an object with constant velocity and an object that is accelerating.

Measure the static and kinetic friction between two surfaces using direct and indirect methods.

Design and conduct an experiment that analyzes the motion of a conical pendulum.

Determine the spring constant of a spring using two methods.

Explore charging by induction and discover how a Leyden jar stores electric charges.

Use a clever apparatus to determine the coefficients of thermal conductivity of three materials.

A fun tool to help teach water concepts.

Visually impacting way to demonstrate an AC and DC generator.

This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.

Economical and effective.

Ideal for Individual Study

Sized For Student Use.

The construction of the multi-functional Demo Electric Motor is completely open.

A simpler version of the Advanced Pulley Demonstration Set, this model includes eight single pulleys and two double sheave pulleys in addition to EISCO ball bearing frictionless pulley.
