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

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

Several questions are embedded within the short film The Day the Mesozoic Died, which tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

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 explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

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 interactive module explores how scientists use the scientific process to learn about the distant past of humans.

This tutorial describes the principles of DNA sequencing and sequence assembly, and shows how they apply to different sequencing techniques.

This tutorial describes how DNA microarrays called Virochips are designed to detect known viruses and discover new ones.

This tutorial explains how scientists analyze and interpret the large data sets generated by DNA microarrays.

This interactive, modular lab explores the techniques used to make transgenic flies and demonstrates how these flies can be used to study gene expression.

This interactive, modular lab explores the techniques used to identify different types of bacteria based on their DNA sequences.
