Spectra Explorations, an introduction the the spectra of common light sources.

Project a spectrum, Use a diffraction grating and an overhead projector to project a spectrum

Project a rainbow with a CD, reflect sunlight into a shadowed white screen and observe a spectrum.

View a spectrum in a CD Look at a minimag light reflected in a compact disk to see a spectrum.

Make a spectrometer Use a cardboard tube and a compact disk to make a spectrometer

Peel CD Peel the aluminizing off a compact disk to make a transmission diffraction grating

Energy Level Model Use the positions of the center of mass of a stool to model atomic energy levels

The Bohr Atom Use a gravity well to model the energy levels in a bohr atom.
