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 identify the science practices and concepts in a Wild Hope episode.

In this collaborative activity, students explore major biodiversity threats and design, present, and refine solutions for preserving biodiversity.

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

This highly customizable activity guides students through organizing and documenting spreadsheet data during a class investigation.

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 activity explores an image of a wildlife overpass crossing a major highway, which serves as a phenomenon for learning about habitat fragmentation and conservation.

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 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.

This Click & Learn shows that keystone species exist across a variety of ecosystems and can exert their influence in different ways.

This activity explores images of a coral bleaching event, which serve as phenomena for learning about marine ecosystems, human impacts, and climate change.

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