Each of these links goes to either a problem with its description, or, in the case of the scenarios, to a new website. All of the activities are Windows compatible. The Virtual Lab also runs on Mac OSX 10.1 or higher.

Mixed Reception A murder mystery activity in which students use concepts of molecular weight and stoichiometry to solve the case (uses video and other multimedia). Mission Critical Chemistry A thermochemistry problem in which students work collaboratively to develop a new fuel for a mission to Mars (uses the virtual lab and simulations). Meals-Ready-to-Eat A thermochemistry problem about heating food while camping (a virtual lab activity). Cyanine Dyes - DNA Combines equilibrium with UV/VIS spectroscopy to explore dyes that self-assemble into DNA templates (uses the virtual lab and a UV/VIS spectrometer simulation). Acid-Base Lab An activity in which students characterize an unknown acid (uses the virtual lab with randomly generated unknowns). Ozone Interpret raw data to determine the rate law and mechanism of stratospheric ozone depeletion (a paper and pencil activity). Arsenic in Drinking Water Set in Bangladesh, this stoichiometry and analytical chemistry activity examines the issues around identifying and remedying wells contaminated with arsenic (a Virtual Lab activity, still under construction).	Virtual Lab A general Lab simulation for aqueous chemistry. Available in multiple languages. Stoichiometry A visualization of limiting reagent calculations.
