Take an elevator down under the surface of the skin! Animations show that new skin cells are formed and the old ones are shed in the epidermis, how melanin provides color and nerves and blood vessels reside in the dermis, and what the...

The fascinating topic of human skin color is examined in this article from Muse magazine. It highlights a study done by a pair of scientists on the relationships among strength of sunlight, vitamins, and melanin in the skin. The results...

The sky appears blue, but why? Humans see the world through the visible light spectrum, but the light spectrum is much larger than what the eye sees. Camera lenses allow people to view the world in ultraviolet, and the changes might...

Lasers attack hair cells from the outside in. Young scholars observe a laser hair treatment in slow motion. They watch as the pulses of the laser destroy the external hair. The Veritasium instructor then describes the process happening...

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...

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...

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...

I can see your epidermis. A short video shows how we get our skin color. It explains how melanocyte cells in the epidermis produce melanin, and that the type and amount of melanin controls skin color.

It's all just skin deep. An anthropologist explains in a video how she used UV radiation data from NASA to come up with a theory on how human skin color has evolved over time. The skin has to be dark enough to block harmful UV radiation,...

Beauty has no color, so why do scientists care about the color of dinosaurs? New evidence turned the world of dinosaurs colors upside down! From adorable red, fluffy dinosaurs to sharply contrasting black and white, these colors inform...

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...

You can't escape your genes. Young scientists learn about recent revelations about how and why hair turns gray. The video in the ACS Reactions playlist highlights certain genes that play a role in this process.

Every minute, your skin sheds more than 30,000 dead skin cells. The sixth video of 47 teaches pupils about the three layers of skin, their composition, and different cell types. It takes a trip through the layers to help individuals...

The thinnest skin on your body is found on your eyelids, and the thickest is found on the soles of your feet. This seventh video in a series of 47 explores how the integumentary system protects people and also helps them interact with...

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...

A handout on genetic inheritance begins with a reading on alleles and how they can result in albinism. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn...

In this integumentary system worksheet, 9th graders list the two major layers of the skin and name the type of tissue composing each layer. Then they describe the structure and function of the hypodermis. Students also list three types...

In this biology worksheet, students identify and locate various vocabulary terms pertaining to integumentary system of the body. There are 27 biology terms located in the word search.
