Education.com is a site I found out about last week. The site has a very diverse range of articles, resources, and links on a variety of educational topics.
The site has activity ideas, worksheets, articles and links to other resources. The "Education A-Z" section has hundreds of articles and links on all kinds of educational topics, ranging from Aspergers to back to school ideas to memory research to youth organizations. It is a veritable cornucopia of information.
The Science Fair section of the site also has some great tips and ideas for students and teachers. There is even a contest for science fair projects.
Education.com is definitely a resource all educators should check out.
