"Dessus de bouchon"

Demonstrate the speed of heat conduction in five different metals.

Demonstrates thermal conductivity differences between materials.

Simple Calorimeter to Measure Heat in Many Applications

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

This apparatus is useful for studying forces during thermal contraction and expansion.

Gain an understanding of materials science and liquid crustals and how they can be used in a variety of technologies.

The liquid convection apparatus is designed to show the convection of heat in a liquid.

Set of discs to study radiant heat absorption based on surface properties.

Employs Guericke’s Method for Demonstrating the Force of Atmospheric Pressure.

Demonstrate the Force of Air Pressure Without a Vacuum Pump

Ideal for demonstrating that vapor pressure increases when temperature increases.

Demonstrate the force of air pressure without a vacuum pump. The edges of the two 8.5 cm rubber cups are placed together and pressed to expel the air between them. Students discover the difficulty of separating the cups by pulling and tugging on the handles - providing an effective, 'hands-on' demonstration of air pressure.

This nickel coated plate uses a rubber pad to achieve air tight contact with a bell jar. It features a stopcock and center hole with safety screw plug and a rubber gasket.

High Quality for the Classroom.

Understand Color and Heat Absorption.

Appropriate for grades 6 to 12 Brings the First Law of Thermodynamics to life! This pair of precision-machined, chrome-plated steel balls is actually a hands-on demonstration in energy transformation. By striking the balls together, you will create enough heat at the point of contact to burn a hole in a sheet of paper.
