Using Images as Phenomena

This hands-on activity engages students in asking questions about phenomena using collections of images.

“Fixing” Gene Expression

In this hands-on activity, students review the steps of eukaryotic gene expression and learn how this knowledge can be used to treat different genetic conditions. The activity reinforces concepts covered in the Click & Learn “Central Dogma and Genetic Medicine.”

Evolution Course

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

Epidemiology of Nipah Virus

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.

Central Dogma and Genetic Medicine

This interactive module uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.

Benefits of Schools

This activity explores images of animals that live in groups, which serve as phenomena for learning about animal behavior.

Developing an Explanation for Mouse Fur Color

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.

Viral Lysis and Budding

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