Florida State University: Vision and Color Perception

Rainbow science anyone? learners put the color specturm, frequency, light waves, and wavelengths into a light speed context. They use algebraic formulas to determine the speed of each light wave length. A great way to connect math and...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

An interesting set of details about the light spectrum, these slides explain how objects reflect and absorb light to affect how they appear to the human eye. The differences in mixing lights or pigments is explained and some everyday...

Skin, the toughest part of the body, provides each person with multiple layers of protection from the outside world. Assist young scientists as they view the video segment and learn the differences in melanin production, leading to...

This site discusses primary lighting sources and gives information on the different properties and spectral characteristics of each. Also includes links to some interactive Java applets.

An in-depth discussion on reflection of light can be found here. Among the topics discussed include are the difference between specular and diffuse reflection, concave and convex mirrors, facets, total internal reflection, and much more....

An interactive simulation that teaches about photons, monochromatic light, white light, and rainbows through changing wavelengths, beams, filters, and color combinations. This simulation can either be downloaded or played online and...

Through illustrated example problems, and some interactive practice, students learn about color addition and color perception.

Objects contain pigments that selectively absorb a wavelength of light, and our eyes only observe a very small range of these wavelengths. Scholars apply these two facts to three different activities. They identify the pigment in an...

Students commonly ask question about vision and color perception which may be difficult to answer without taking. They use this module that contains a list of questions which often arise when biology students are studying the nervous...
