Designing Cancer Drugs: Development of Gleevec

Follow the steps in the development of a cancer drug — from initial research on the targeted disease to the drug’s use in humans. Learn how drug design targets a disease by exploiting the structure of a protein that causes that disease. View non-Flash version.

Discovering Neutrino Oscillation

Discover neutrino oscillation and try to match real experiments with this simulator. Do electrons oscillate? What happens to the rate of neutrino detection as you move closer and farther from the source?

Disease Lab

This simulator will let you explore various diseases: Kold, a caricature of the common cold; Impfluenza, which resembles an influenza outbreak; and Red Death, a fast-spreading epidemic with a high mortality rate. What factors influence the spread of these diseases, and what can we do to counter them?

Divergent Boundaries - Spreading Plates

What happens as boundaries diverge? Watch a continental rift, volcanoes and lakes form as two continental plates move apart.


Learn about genetics, genetic engineering, the Human Genome Project and the ethical implications of these new technologies.

DNA Assessment: Test Your Skills

Test your knowledge of DNA, RNA, genes, genomes, transcription and genetic engineering. Take this 40-question test, review your answers, and print out your assessment.

DNA Timeline

Explore the history of DNA on this interactive timeline. Discover key moments in the study of DNA as well as more recent developments in DNA technology, such as genetically engineered food and cloning.

Dynamic Earth

Delve into the structure of the Earth to learn what causes earthquakes, volcanoes, and more.

Dynamic Earth Assessment: Test Your Skills

Test your knowledge of the earth’s layers and the shifts that create mountains, volcanoes and earthquakes. Take this 30-question test, review your answers, and print out your assessment.

Earth's Plates

Examine clues about the behavior, history and appearance of various volcanoes. Then try to locate the volcanoes on the map.

Ecology Lab

Build your own ecosystem, and explore the effects of these interrelationships.

Economic Timeline

The economic landscape has drastically changed throughout history. Use this timeline to dig deeper, discover relationships, and explore concepts.

Elections and Issues

You've just found out that your neighborhood has been declared a gun-free zone. Choose which side of the issue you are on, and decide which civic actions you will take to support your position.

Elements of Authentic Instruction

Analyze three classroom segments and identify teaching strategies that illustrate authentic instruction. Give examples to support your answer and compare your answers to those of other teachers.

Energy Lab

Try to meet the world's projected energy demand by choosing from the available energy sources, while keeping atmospheric CO2 under control. You must avoid the limits and pitfalls associated with each energy source.

European Colonies Challenge

See how much you know about the European powers and the colonies they established in North America. Then boost your score in the lightning round as you locate the original 13 states.

Evaluating Evidence

Evaluate primary sources to determine their support of a given thesis. Using the Civil War as an example, rank the relevancy of sources in relation to four common beliefs as to the cause of the war.

Evolution of Large Scale Structure in the Universe

Vary two of the most important cosmological parameters, run the simulation and try to build our universe. Compare your simulated universe to real observations.

Evolution of Túngara Frog Mating Calls

Use molecular information and observe female response patterns to learn about the mating calls of Physalaemus frogs. Examine the evolution of female preference for particular call characteristics. View non-Flash version.

Executive Branch Recap: The Bureaucracies

The departments and agencies of the executive branch are responsible for regulating many of the things we use in our everyday routines. Follow a student through her day to find objects regulated by the government.
