Do you know how transistors work? These simulations, designed for technology and engineering students, will walk you through the physical principles of field effect transistors, and explain how they are used to construct logic gates.

The following images show some selected MW activities produced by the Molecular Workbench Team of the Concord Consortium. Clicking an image will launch an MW activity.

Transistors	Quantum mechanics	Cellular respiration	Diffusion	Heat and temperature
Electrostatics	Phase change	DNA to protein	Newton's Laws	Lipids & carbs
Proteins & nucl. acids	Harvest light	Tree of life	Fluid mechanics	Chemical bonding

Besides using existing simulations, MW is also a modeling tool for teachers and students to create their own simulations. Currently, MW supports three types of simulations: classical mechanics simulation, molecular dynamics simulation, and quantum dynamics simulation. MW allows you to easily share your simulations with collaborators. Learn more in MW's Online Manual…

MW also has an authoring system for teachers and curriculum developers to create or customize their own online lessons that use models and simulations. A typical MW activity consists of a series of scaffolded pages that contain text, simulations, graphs, navigation links, and embedded assessments. The user interfaces of simulations in MW can be customized for students of different levels (grades 6-16). When learning with an MW activity, students can save their work in an Internet portfolio, create reports, and submit reports for grading. Learn more in MW's Online Manual…
