Resources to Teach and Learn Chemistry
The ChemCollective is a collection of virtual labs, scenario-based learning activities, tutorials, and concept tests. Teachers can use our content for pre-labs, for alternatives to textbook homework, and for in-class activities for individuals or teams. Students can review and learn chemistry concepts using our virtual labs, simulations, and tutorials. The ChemCollective is organized by a group of faculty and staff at Carnegie Mellon who are interested in using, assessing, and creating engaging online activities for chemistry education.
