Lizards in Hurricanes

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.

Lizards in the Cold

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

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.

Analyzing Data on Tuskless Elephants

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.

Modeling Food Webs in Darién, Panama

In this activity, students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level using information from the citizen science website WildCam Darién.

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.

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.

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..

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.
