- Earth Science Share-a-thon – great collection of ES labs, lesson plans, collections of regents questions, etc. (Lives within the newyorkscienceteacher.com site – not all the discipline sections are as well stocked as the earth science section of this site.)
- GSA Teacher Resources
- Digital Library for Earth System Education – VERY well organized and cataloged site supported by the NSF, which includes a “reviewed” category of “exemplary” materials as well as a much larger collection of material that is searchable by grade level, topic, etc.
