Color Pigments
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...

Study Jams! Light
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...

Chromatography - Color Clues
Here's an activity that will change how one sees color. Pupils try out an experiment on chromatography where they place a drop of food coloring on a coffee filter, add several drops of water, and watch the colors spread and separate....

Leaf Chromatography
Pigmentation of leaves is important in plant processes. Scholars use chromatography to create a better picture of the pigmentation in an assortment of leaves. They share their results to make comparisons between different plant species.

DNA Forensics and Color Pigments
Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

Restriction Enzymes and DNA Fingerprinting
Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Mixtures and Solutions: Paper Chromatography Experiment
Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...
Curated OER
Simplified Botany--Leaf Chromatography
Students investigate the different pigments contained in green leaves by completing an experiment that strips away the chlorophyll and separates the pigments left behind.
