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

This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.

This activity allows students to formulate and analyze scientific questions.

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.

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

This short video explores the science behind fecal microbiota transplants, a method of transplanting stool from healthy donors to sick patients to treat certain diseases.

This short video explores how bacteria have evolved mechanisms to resist antibiotics.

This short video explores a method for using bacteria to prevent mosquitoes from transmitting dengue virus to humans.

This short video explores the mechanism by which a beewolf wasp passes antibiotic-producing bacteria to its 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.

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

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.
