In this card activity, students investigate the functions of major digestive organs.

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 Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
 

This activity guides the analysis of a published scientific figure from a study that investigated how human populations might adapt to milk consumption, both genetically and culturally. 

This activity explores an image of fossil footprints at Laetoli, which serves as a phenomenon for learning about fossil evidence and human evolution.

This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.

The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.

This activity explores an image of a moth with unusual markings on its wings, which serves as a phenomenon for learning about mimicry and adaptation.

In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

This activity explores images of anole lizards subjected to strong winds, which serve as phenomena for learning about natural selection and the impacts of extreme climate events.

This activity guides the analysis of a published scientific figure from a study that investigated how anole lizards may adapt to extremely cold temperatures.
