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...

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...

Genetic variation makes for stronger species, but for a mammalian species, humans are disturbingly closely related. Help your class explore human ancestry and genealogy using the 15th video in a 16-part series. It describes how we became...

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...

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....

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.

Nature provides a rainbow of colors at one's fingertips. A hands-on activity uses natural plant materials to create all-natural dyes. Plants range from fruits and vegetables to flowers and greens. After extracting the pigments, eager...

The oddball reptiles, chameleons, can teach animal lovers a little something about nanotechnology. Viewers peel away the layers of the chameleon skin to discover the different types of chromatophores using an episode of a larger series...

All life requires energy ... and the connection between energy and plant life typically requires photosynthesis. Scholars explore photosynthesis in depth from ATP/ADP through the Calvin cycle. A helpful presentation highlights concepts...

Drosophila includes more than 1,500 species and often find themselves studied by geneticists. A scientist presents a lecture on one example of these studies on the paintbrush gene. The gene determines the amount and color of pigment on...

Why so blue? As it turns out, very few things in nature only reflect blue light! A short video from a comprehensive science playlist highlights the beautiful blues of butterflies, birds, and human eyes. The narrator shows how adaptations...

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...

Is there really more than one black? Although your crayon box may tell you otherwise, some blacks are, well, blacker than others! Discover the cutting-edge technology at work to produce the blackest black possible with a video from the...

Redheads have genetic modifications that affect their pigmentation; however, the differences don't stop there!  Use the video lesson from the ACS Reaction series to examine different traits specific to redheads. Learners consider the...

Talk about weird science! Young biologists discover the amazing structures found in the skin of male chameleons during a video from Veritasium. The narrator discusses common myths about chameleon color change, what triggers the...

Things are not always as they appear. The morpho butterfly appears to have blue wings, but they don't contain a drop of blue pigment. Learners watch as the instructor explains the physics behind these amazing blue wings.

Why do leaves change color in the fall? The video explains the relationship between chlorophyll and light, connects the concepts of light to photosynthesis, relates the visible color spectrum to electromagnetic radiation. 

Zounds! Who'da thunk it? Colors can be deadly. Viewers learn about the dangers of white (lead), green (radium and cupric hydrogen arsenic), and orange (uranium oxide) pigments used in clothing, ceramics, and home decor.

Dry erase markers work on desks, doors (made of shiny particle board), and even mirrors! A funny video explores why dry erase markers leave behind marks when used. The narrator explains what the markers are made of, specifically the...

The composition of teeth are such that when exposed to a black light, they absorb the UV light and glow! A radical video explores how different objects glow in the dark. The narrator discusses how different types of chemicals, called...
