This week we looked at Twitter.  I signed up and found a whole new world of contacts and ways to use it in my classroom.  I think using it to start discussions at the beginning of the class would be a good way to engage the students.  Each student could follow a different organization having something to do with science.  National Geographic or NASA, for example.

LiveBinder was suggested as a way to keep our online worlds organized.  I have not done anything more than just set up an account but plan to look at it in more detail when I can.
