This site links to chemistry classroom management and activity resources. It also has a lot of fun links that relate chemistry to other subject areas from history to poetry.

Awesome animated video that gives an introduction to some aspects of quantum behavior, wave/matter properties and interference patterns.

This site links to 47 different high school level chemistry labs. Materials/setup lists and procedures are included as well as follow up questions.

This looks like a great website. It covers around twelve general chemistry topics and includes teacher resources, activities, videos, and labs for students.

This is a cool site with general chemistry tutorials, demonstration videos, and documents that explain the chemistry involved in each demonstration.
