1. followed blogs of marine biologists and commented
2. I believe that social networks are a useful tool for sharing ideas and thoughts on how to better our classrooms. If one teacher stumbles upon a useful website that can help demonstrate a concept it can benefit everyone if that person can share the web address and put that "tool" in the hands of all concerned. Although some thoughts really don't need to be shared publicly!
3. A useful website for marine biology is http://www.marinebio.org/ which is staffed by students and professionals that allows us to look at plankton samples and ask questions.
