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 activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This activity explores images of plant cells and structures, which serve as phenomena for learning about how plants respond to stimuli.

This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.

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.

The activity introduces students to the concept of biomes, using Gorongosa National Park as a case study. Part of the activity involves exploring the Gorongosa National Park Interactive Map.

This animation shows how HIV infects a cell and replicates itself using reverse transcriptase.

This animation shows how a genetically modified virus can be used to destroy cancer cells.

This animation shows how proteins in the cell are tagged for disposal by ubiquitin and then degraded by the proteasome.

This playlist can be used to teach several core topics in ecology by connecting students to actual research being conducted in Gorongosa National Park in Mozambique. It can be used in general high school biology and environmental science courses.
