Virsonas are "Virtual Personas," created to Reason, Remember and React in the same way that a living, fictional or historical person would. You can create the "Virtual You" as a Personal Virsona™ or you can create and / or interact with one of our Community Virsonas. Interacting with our Community Virsonas opens up a world of possibility - you can actually talk directly to one of your heroes, conduct research or simply have FUN! You can also create Virsonas of departed loved ones, your pet(s), as well as for commonly shared experiences, for example; "The First Kiss."
Site lets teachers post a question online. Students then respond via webcam (no account required) and have their (moderated) comment added to a really great-looking video wall online. Site does cost $65 annually, but that includes 10 walls and virtually endless questions/responses.
Really nice collaborative science site. Access resources, partake in discussions, set up virtual classroom spaces, connect to other teachers, scientists, etc.
