Chemistry resources for teachers include the Royal Society of Chemistry site and the California State University site for chemistry. The RSC site has items such as interactive lab primers, the periodic table and an aspirin screen experiment among other modules.
The California State University site for chemistry has reference links such as the periodic table, measurement resources, and demonstration and experiment ideas. The site also has links for chemistry textbooks and places to order laboratory equipment. Another resource is the National Science Foundation, which contains lessons and Web resources for chemistry teachers. Many of the resource links are organized by the grades they are appropriate for.
