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 images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.
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 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.
