Biology of SARS-CoV-2

This three-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

Evolution of Ant-Mimicking Beetles

This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.

Sodium Channel Evolution in Electric Fish

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

Cancer Cell Invasion

This activity explores an image of tumor cells invading muscle tissue, which serves as a phenomenon for learning about cancer, mutations, and cell division.

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. 

Role of p53 in the Cell Cycle

This activity analyzes a published scientific figure from a study that investigated the role of p53 in cell cycle regulation.

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.

Viral Lysis and Budding

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

HIV Receptors and Co-receptors

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

HIV Reverse Transcription and AZT

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

Viral DNA Integration

In this hands-on activity, students model how a double-stranded DNA copy of the HIV genome is integrated into the host cell DNA.
