Description

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

The animation briefly explains the basic structure of the skin, then concentrates on the part of the skin responsible for developing skin color. Students learn about the functions of melanocytes, an important type of cell that produces the color pigment melanin. The animation also explores the biological basis of variation in skin color, and how it is related to melanin, vitamin D synthesis, and protection against the harmful effects of UV radiation, which has important implications for health.

Depending on students’ background, it may be helpful to pause the animation at various points to discuss different cell types and structures.
