Principles Illustrated: Blackbody Radiation

Location: Back Counter

A light bulb glows in the visible range as the filament is heated demonstrating blackbody radiation.

Location: Cabinet D, Shelf 2

A metal ball is heated with a propane torch causing it to glow and demonstrate blackbody radiation.

Principles Illustrated: Curie Point

Location: Cabinet F, Shelf 3

Canadian quarters (which have some iron in them) are picked up by a magnet, and heated by a torch. As each quarter heats up to its curie point, it falls off the magnet into a container of water below. After the quarter enters the water which cools it down, it can be picked up again with the magnet.

Principles Illustrated: Radiation

Location: Cabinet C, Shelf 5

A variety of calibration samples and raw ore samples are available. For large classrooms, an amplified speaker is attached to make the audio output louder. Background radiation is easily demonstrated, as well as shielding.

Principles Illustrated: Magnetic field expulsion

A YBCO superconductor disc is cooled with liquid nitrogen. A tiny cubical permanent magnet is suspended above the superconductor.

Our video camera and projector system is used to make this demo visible to classrooms.

Principles Illustrated: Spectra and diffraction grating

Location: Cabinet G, Shelf 2

A variety of gases are available. Students are given diffraction glasses. Spectra of the various gases can be viewed.
