In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.

This video follows biologist Shane Campbell-Staton, who is studying the adaptations that allow deer mice living at high elevations to stay warm and active during the winter.

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

This activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

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.

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

This animation zooms into a coral reef to explore the tiny animals that build reefs, the photosynthetic algae inside their cells, and the damaging process of coral bleaching.

This tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.
