This activity guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.

This film explores the foundational research in the Serengeti National Park, Tanzania, that uncovered many of the ecological principles that govern how animal populations and communities are regulated.

This activity explores an image of termite mounds in the African savanna, which serves as a phenomenon for learning about ecosystems, competition, and feedback loops.

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 used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

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

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

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.

In this activity, students model trophic cascades, which are also explored in a variety of related resources, using cards of animal and plant species from seven different habitats.
