This activity explores images of tree growth in the Serengeti over time, which serve as a phenomenon for learning about and modeling species interactions in ecosystems.

In this activity, students use an interactive tool to simulate how scientists collected and used sample data to estimate elephant population sizes.

This activity guides the analysis of a published scientific figure from a study that explored inbreeding depression in a small, isolated population of wolves.

This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

In this activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti.

In this inquiry-based activity, students engage in science practices to figure out ways environmental factors drive the natural selection and adaptation of Galápagos finches.

In this activity, students analyze scientific figures to understand principles of island biogeography theory that determine the number of species in an isolated habitat.

This activity guides the analysis of a published scientific figure from a study that explored the relationship between species number and habitat size for arthropods living on desert shrubs.

This activity guides the analysis of a published scientific figure from a study that explored the relationship between species number and habitat isolation for arthropods living on desert shrubs.

This activity guides the analysis of a published scientific figure from a study that explored habitat fragmentation and corridors in a model ecosystem.

In this activity, students work with authentic research data to explore the impact of poaching on African elephants.

In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.
