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

In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

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

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

This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.

This interactive module connects to an online citizen science platform for identifying animals in photos collected by trail cameras in Darién and Soberanía National Parks in Panama.

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

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

This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population.

This interactive module allows students to investigate their own ecological questions using data collected by trail cameras in Gorongosa National Park in Mozambique.
