Andrea, as a biology teacher, do you cover oceans and ocean sustainability?
Digital Ocean: Sampling the Sea is a collaborative global project from researchers at UC Santa Barbara. They want middle and high school science teachers to participate in a project on seafood and ocean sustainability in March-May. You can get info from the link at http://www.epals.com
They are using the new ePals LearningSpace as a way to organize student contributions, etc. (LearningSpace is a virtual workspace with digital lockers, multiple web 2.0 tools, automatic language translation, and a high degree of student safety. See a short demo at: http://learningspace.epals.com.)
