ChemCollective is a project in the National Science Digital Library (NSDL) that is supported by NSF and Carnegie Melon University. ChemCollective provides resources designed to support teachers of chemistry in designing engaging and interactive online activities for students. ChemCollective has been around for several years but they recently redesigned their web presence so you may want to check it out. Some of the chemistry teaching and learning tools will find on the site include:

• Virtual Lab Problems
• Tutorials
• Real-World Scenarios
• Particulate Level Visualizations
• Simulations
• Concept Tests
• Resources organized by chemistry topics
