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.

In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO₂ starting in 1958.

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.

The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.

This video case study explores whether fungicides play a role in the decline of bee populations.

This activity guides the analysis of a published scientific figure from a study that modeled the impact of an infectious fungal disease on a bat population.

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 guides the analysis of a published scientific figure from a study that investigated the effects of tourism on cougars and cottonwood trees in a national park.
