WONDERFUL site when teaching the organelles of the cell and the differences of mitosis/ meiosis and bacteria and viruses.

Yes, the Smithsonian Institute. "Visits" to the National Museum of Natural History and Air and Space Museum are some of the favorites.

The Biology Corner is a gift when it comes to ideas for lessons, online dissections and quizzes, along with videos for the Biology classroom.

Great resource for ANY science teacher! Too many resources to mention.

May seem odd, but I like this site for the lecture series that is presented on topics in Biology, often by the authors of the textbook I use and other guests working on biology-related studies and the bioInteractive virtual labs.

This site has saved my bacon a number of times when the filters on the schools network won't allow a You-tube video to play and I can play the same video through this teacher and student video site.

Great, simple site that allows students to review the periodic table and possibly learn something new when they "interact" with it.

Great site to help students choose or at least narrow their search, of famous scientists that I often use as a report early in the year to estimate the students level of literacy.

Interesting site that has a good number of "fun" experiments instead of the "cookie cutter" experiments that come with the text supporting materials.

Great place for lesson ideas and informative videos.
