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. 

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

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

This interactive module explores key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity.

This interactive module examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.

This interactive module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times.

This tutorial introduces students to vector-borne disease with a focus on dengue fever, which is transmitted by mosquitoes. Students also learn about strategies designed to stop the spread of disease by interfering with the mosquito life cycle.

This tutorial explores the effects of West Nile virus infection on different organisms and describes how the virus has spread throughout the United States since 1999.
