Classroom Resources

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

This interactive tool introduces students to building scientific models. Educators can use the tool to create assignments and, in some cases, automatically grade student models. 

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.

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.

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

This interactive module explores niche partitioning, a mechanism that enables similar species of animals to coexist.

This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

This interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.

This interactive module explores different anatomical features of the human body and what they reveal about the evolutionary history of humans.

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

This interactive module explores how the changes in oxygen levels throughout Earth’s history have impacted the planet’s environment and types of life.
