Serial Dilution of CuSO4 and Changing the Value of Paint

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...

Whether or not you think mice are nice, you'll love the colorful activity! Scholars examine evidence for evolution in the rock pocket mouse through video, discussion, and collaborative work. Learners watch a video regarding variation in...

Is your smartphone really doing its best work when it comes to color? The narrator describes technology's lazy approach to recreating colors in an insightful video. Science scholars discover how digital cameras store...

Is our skin color determined only by genetics? Explore skin science through a video and related interactive. Young biologists discover the cells of the epidermis, how melanin is made, and the factors that influence the outward appearance...

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...

What makes the ocean blue but a glass of ocean water nearly colorless? Investigators prepare tubes of water to examine the color of water. Scholars discover the relationship between light absorption, color variations, and water depth as...

Filters provide amusing changes to images in applications other than just Instagram! High school pupils apply their knowledge of colored filters to three different interactive sets of puzzles. They identify light colors that pass through...

The dress color debate of 2015 taught the importance of understanding how we see light. Scholars view a shirt under two different colored lights and then must predict what color the shirt will appear under a third light. They apply color...

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...
