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.

Interactive Assessment for The Day the Mesozoic Died

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.

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.

Exploring Transitional Fossils

This interactive module allows students to examine fossils of fish, tetrapods (four-limbed animals), and their transitional forms.

Paleoclimate: A History of Change

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.

Geological History of Oxygen

This interactive module explores how the changes in oxygen levels throughout Earth’s history have impacted the planet’s environment and types of life.

Deep History of Life on Earth

This interactive module explores key events in the record of life on Earth, which stretches over three billion years.

EarthViewer

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.

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.
