Project to make lab sessions more useful for learners. Builds on Moodle 2 with some custom PHP. Still a development project - see the docs at the bottom of the page for better detail.
Looks a good resource but looks like its school level.
"The Chemistry Collective is a collection of virtual labs, scenario-based learning activities, and concepts tests which can be incorporated into a variety of teaching approaches as pre-labs, alternatives to textbook homework, and in-class activities for individuals or teams. It is organized by a group of faculty and staff at Carnegie Mellon University for college and high school teachers who are interested in using, assessing, and/or creating engaging online activities for chemistry education"
