Explore color through an examination of pointillism and light. Class members view Georges Seraut's famous painting on a computer, zooming in and out to see the details and effects of the technique. They then cover how light and color are...

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...

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...

Students explore light and color, including how colors are mixed to produce new colors, how light is filtered, and how light is reflected off of surfaces. They read materials provided, complete worksheets, and complete hands-on activities.

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

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...

Students explore the nature of light. They use on-line articles and a worksheet to explore the roles of the eye and brain in the perception of color. They draw and label a diagram illustrating the movement of light.

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...

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...

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...

Learners investigate solar energy and color. In this solar energy activity, students assess the benefits of solar energy. Learners discover that solar energy is attracted to darker colors and conduct an experiment using colored...

Photocopy single-color images onto acetate transparencies and either demonstrate or have your class experience the combination of colors to produce images. Children will learn that cyan, magenta, yellow, and black combine to make all of...

Students explore the relationship between light and color. They explore the NineColours computer program, blend colors, create a slideshow of hues of colors, and conduct an experiment using a flashlight and colored cellophane.

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

Students explore light and color, including how colors are mixed to produce new colors, how light is filtered, and how light is reflected off of surfaces.

Gummy bears are tasty, but did you know they are also used to determine color and light properties? Use the activity as a way to demonstrate light absorption, light reflection, and refraction with high schooler....

Second graders make spinning color wheels to determine how energy effects what colors look like. They paint or color a color wheel with the seven colors of the spectrum. Next, the spin the wheel to determine what happens. In order to...

Skin color is controlled by at least six genes. Young scientists learn about skin colors through a documentary. They discuss the topics of pigment, natural selection, and vitamin D absorption. They apply their knowledge to higher order...

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

Humans can only see visible light, but some insects can see ultraviolet light. Through a simulation, pupils explore how we see colors using one bulb. It moves on to demonstrate how we see colors by mixing three different bulbs (red,...

How can we change the color of what we are seeing? The simulation allows individuals to change the color of a car's paint, the color of light pointed at the car, and the color of glasses the person is wearing. Each combination creates a...

Investigate color, light and excited electrons and produce waves using slinkys. Your high schoolers will observe a continuous spectrum with a prism and an overhead projector. They observe flame tests to identify elements and they observe...

Light intensity varies by the strength of the light bulb as well as the distance to the light bulb. Pupils apply these concepts independently at first. They must solve for the light intensity as either the distance or the wattage of the...
