"SCIENTIFIC HATCHERIES"

Laminated for long use.

Ball and Ring Apparatus demonstrates thermal expansion.

Hands on demomstration showing the power of a vacuum.

Ideal for demonstrating that vapor pressure increases when temperature increases.

Ice Melting Blocks are a unique way to teach principles of conductivity of heat and the scientific method.

Bring the 2nd Law of Thermodynamics to life.

Bimetallic strips attached to wooden handle to study thermal energy.

Radiometer with four lightweight metal arms.

Metal cylinder set for demonstrating density investigation and specific heat experiments.

Ideal for exploring force of friction.

This is a classic example of thermodynamics in action.

Accurately plot the thermal energy transferred by an aluminum bar.

Organize the study the disorder.

Vividly illustrate the transformation of energy.

Demonstrate how the frictional force on an object depends on the surface, not mass.

A dramatic visualization of air pressure. This 1000 ml bottle has a balloon attached to its neck and an additional hole in its base fitted with a rubber stopper. You cannot inflate the balloon with the stopper in place, but remove the stopper and the balloon easily inflates. Replace the stopper, fill the bottle with water, remove stopper and Whoosh! – a geyser erupts!
