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.

In this inquiry-based activity, students engage in science practices to figure out ways environmental factors drive the natural selection and adaptation of Galápagos finches.

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 asynchronous course is designed to deepen educators' content knowledge in evolution, especially regarding content appropriate for teaching at the high school level.

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.

In this activity, students explore different ways of calculating t-values and performing t-tests using built-in functions in Excel or Google Sheets. Students apply what they learned by plotting beak size measurements of Galapágos finches collected before and after a drought.

In this activity, students explore different ways of constructing a histogram using Excel or Google Sheets. Students apply what they learned by plotting beak size measurements of Galapágos finches before and after a drought.

In this activity, students develop arguments for the adaptation and natural selection of Darwin’s finches, based on evidence presented in the film The Beak of the Finch.

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.

In this activity, students use the built-in functions in Excel or Google Sheets to explore different ways of filling in cells with a series of numbers, copying and pasting formulae, and referencing individual cells to use in calculations. Students apply what they learned by making different calculations with beak size measurements of Galapágos finches.
