The "ChemCollective's goals are to support a community of instructors interested in improving chemistry education through interactive and engaging online activities. The website, created by Carnegie Mellon University for college and high school teachers, allows users to easily find activities to use in the classroom, modify or create activities, submit activities and websites, and discuss issues in improving teaching and learning in chemistry. Educators can determine which activities are right for their classroom with the provided difficulty ranking and instructor comments. Students can enjoy learning about chemistry by solving a murder mystery and participating in the countless other excellent virtual activities. There are virtual laboratory activities which can be used by downloading the virtual laboratory software.
