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 highly customizable activity guides students through organizing and documenting spreadsheet data during a class investigation.

This web tool provides a quick and easy way of visualizing and analyzing data without advanced technological requirements.

In this activity, students work with authentic research data to explore the impact of poaching on African elephants.

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.

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.

This interactive simulation allows students to graph and analyze sample distributions taken from a normally distributed population.

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 calculate the mean and median. Students apply what they learned to a dataset beak measurements of Galapágos finches.
