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. 

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 the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.

This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

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

This interactive module allows students and educators to document, annotate, and reflect upon scientific research processes.

This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.

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.
