Diving Adaptations in Sea Nomads

This activity guides the analysis of a published scientific figure from a study that investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.

Coloration in Vertebrates

This activity explores images of animals with a mutation that affects coloration, which serve as phenomena for learning about skin color genetics and evolution.

Skin Color and Human Evolution

This activity guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.

White-Nose Syndrome

This activity explores images of bats with an infectious fungal disease, which serve as phenomena for learning about population dynamics and disease impacts.

Age Structure of Ebola Outbreaks

This activity guides the analysis of a published scientific figure from a study that investigated demographic patterns in Ebola outbreaks from the Democratic Republic of the Congo.

New Laetoli Footprints and Hominin Body Size

This activity guides the analysis of a published scientific figure from a study that used footprints formed millions of years ago to estimate the heights of early human ancestors.

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.

Using Wolbachia to Suppress Mosquito Fertility

This activity guides the analysis of a published scientific figure from a study that tested whether releasing mosquitoes infected with Wolbachia bacteria could reduce mosquito populations..

Patterns in the Distribution of Lactase Persistence

This activity extends concepts covered in the film Got Lactase? The Co-Evolution of Genes and Culture. Students analyze data from the scientific literature to draw conclusions about the geographic distribution of lactase persistence.

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 Protease Inhibitors

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

Ebola: Disease Detectives

This hands-on activity allows students to analyze DNA sequences of Ebola viruses. Students use these sequences to track the virus’s spread during the 2013–2016 Ebola outbreak in West Africa.
