cstaindex_02.jpg I just came back from the CA Science Teachers Association in Long Beach — a very good time. I like science teachers. They’re erstwhile, smart, and care about kids. I gave a presentation on electrostatics — you can download my handouts.

I saw one very good presentation on how to transform traditional cookbook-type labs to be more inquiry oriented and engage the kids. Check out his pretty pictures of dissolving M&M’s! I also liked his activity for showing radioactivity using M&M’s, and showing the probability wave around an atom using markers.
