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

This interactive video explores how two scientists tracked the 2013 Ebola outbreak in West Africa. 

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

This interactive module can be used to model infectious disease spread in a population. It includes background on the SIR model and two simulators for modeling disease spread on different scales. 

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 interactive video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.

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.

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 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 explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

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