In this activity, students investigate the phenomenon of lactase persistence by making sense of a series of data sets.

This activity guides the analysis of a published scientific figure from a study that explored inbreeding depression in a small, isolated population of wolves.

In this inquiry-based activity, students investigate the phenomenon of fur colors in rock pocket mice to connect genotypes to phenotypes and molecular genetics to evolution.

This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations.

This activity guides the analysis of a published scientific figure from a study on how social status affects the expression of genes involved in immune system processes.

This activity analyzes a published scientific figure from a study assessing if the microbiota from a mother affects the immune systems of the developing offspring.

This activity complements the video Virus Hunter: Monitoring Nipah Virus in Bat Populations. Students explore cases of Nipah virus infection, analyze evidence, and make calculations and predictions based on data.

In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.

This activity outlines two demonstrations that model how enveloped and nonenveloped viruses are released from infected cells.

This demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.

This activity allows students to model how the anti-HIV drug AZT (azidothymidine) interferes with the process of viral replication.

This demonstration models how the HIV protease enzyme functions and how its activity is blocked by a class of anti-HIV drugs.
