Location: 
Bd4
A small turbine rotator turns when placed above a heat source.

Spencer Disk (Hopping Disk)

Catalog: 
4A30.40
Location: 
Bimetal disk are heated in your hand and then "cocked". When the disk is set on a cool hard surface, heat is transfered from the disk causing it to snap back into it's origianl position and hopping off the surface.

Liquid Crystal Sheets

Catalog: 
4A10.50
Location: 
Heat sensitive sheets change colors depending on the temperature. Our sheets are sensitive to temperatures between 23deg C and 27deg C.

Drinking Bird

Catalog: 
4C31.30A
Location: 
Wet the bird's beak and watch him drink. As the water evaporates off of the beak, it condenses the gas inside. This causes the amount of liquid in the bird to increase and rise, throwing it off balance and dunking its beak in the water again. As the liquid in the bird changes back into a gas the bird rises and the process repeats.

Boyle's Law

The syringe and the Pressure Sensor-Absolute are connected.

A graduated syringe is connected to a pressure sensor displayed on Data Studio. As the volume on the syringe changes the corresponding change in pressure is shown.

Ideal Gas Law Syringe TD8596

The pressure sensor and thermistor sensor are attached.

Presure, Volume and Temperature are measured at once. The volume is read from the syringe and the temperature and pressure are displayed on Data Studio. As you vary volume you can see the how pressure and temperature react.
