Interactive Exploration of How We Get Our Skin Color
The added information provided at pause points within the animation How We Get Our Skin Color allows for a richer exploration of the topic of human skin structure and function.
How We Get Our Skin Color explains the connections between the anatomy and function of our skin, particularly in relation to our health. Students learn about the roles of the different layers of cells in skin and dive deeper into the functions of melanocytes, a type of cell that produces the pigment melanin. The animation also explores the relationships between melanin, skin color, vitamin D synthesis, and protection against the harmful effects of UV radiation.
This version of the animation contains automatic pause points, during which students access additional information in the form of text and illustrations, videos, questions, and fun interactive widgets.
