Color

Laser Jello -See wsw snacks

Chromatography- Students put one spot of black Sketch felt pen ink on chromotography paper then dip in water. The colors separate and run up the paper. I put the water in Petri dishes so that the students are less likely to dunk the paper.

Color Addition -Colored Shadows, Snackbook.

Colored Overheads-I obtained 4 overheads, one in each of the primary pigments, and black. The students overlap these recording what colors they observe.

Colored Cubes-Students make observations while overlapping cyan, magenta, and yellow acrylic cubes (purchased at Children's Discovery Museum-you could make your own with gelatin)

Colorblindness Test Book- Color Table, Snackbook. (The book is borrowed from our physiology course) Besides checking to see if there is "colorblindness", students cover pages with yellow or orange filters to simulate what the "colorblind" might see.

Benham's Disk-purchased from the Exploratorium store.

Retina Fatigue-Students stare at the cyan, magenta, and black flag from Seeing the Light. Students may have better success with the image available over the web at ....

Dichroic Filters-I acquired these at an optics workshop, you may be able to get some reject laser mirrors or get some aurora wrapping cellophane.

Yellow + Green = ? Students place the yellow filter over a "real" blue book cover .

Prism/Diffraction Grating- Spectra, Snackbook. Students observe which color is bent the most through the prism and then through the diffraction grating.

Colored Lights on Colored Rings- Bridge Light, Snackbook. Students shine colored flood lights one at a time on to a Fisher-Price ring tower.

Color Subtraction-While looking through diffraction grating students lower red and green filters over in front of a single filament bulb.

Red& Blue 3-D-Students look through glasses made of one blue and one red filter while looking at some drawings made with both colors. (If you have these and white boards have them look at words writen in red and blue ink-Wow!)
