Understanding Global Change

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.

Genetic Mutations and Disease

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

Sampling and Normal Distribution

This interactive simulation allows students to graph and analyze sample distributions taken from a normally distributed population.

The Eukaryotic Cell Cycle and Cancer

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.

Lizard Evolution Virtual Lab

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

Stickleback Evolution Virtual Lab

This interactive, modular lab explores how stickleback fish and fossil specimens are used to study evolutionary processes, with an emphasis on data collection and analysis.

Symbiotic Bioluminescence

This tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.

Bacterial Quorum Sensing

This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.

Electrical Activity of Neurons

This tutorial describes how neurons generate action potentials, and how scientists measure neuronal activity and record the firing of individual neurons.

Cells of the Immune System

This tutorial provides an overview of the immune system, concentrating on the roles played by B and T lymphocytes, and on the antigen-presentation system.

Tissue Regeneration in Animals

This tutorial describes how animals differ in their abilities to heal wounds and regenerate lost body parts or damaged tissues.
