Or that most things that glow in the dark are not radioactive.<BR/><BR/>People have an irrationally high aversion to radiation. Teachers should try to demystify radiation. I was surprised by the response of the crowd when I heard Lovelock (author of Gaia) speak at the Cal Academy about using nuclear power as an alternative to petrochemicals. Here is a man who has dedicated his life to analyzing environmental issues, published one of the most famous books on the subject, getting booed by the audience.

Only Chem Standard 11.e. looks like fertile ground for lab work, and it's a starred standard (not assessed on the CST).Dean Bairdhttps://www.blogger.com/profile/17681829220589441713noreply@blogger.comtag:blogger.com,1999:blog-31189917.post-1164776406948053622006-11-28T21:00:00.000-08:002006-11-28T21:00:00.000-08:00Don't send your radioactive samples to hazmat.

Hands-on radioactivity labs using digital Geiger counters are very engaging for students.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-31189917.post-1164495145933174572006-11-25T14:52:00.000-08:002006-11-25T14:52:00.000-08:00Yes; the Fiestaware has a uranium-based glaze!

But I never thought a frenzied Geiger counter was terribly dramatic as a classroom demo. Students likely think, "Yeah, I can get static on my radio, too."Dean Bairdhttps://www.blogger.com/profile/17681829220589441713noreply@blogger.comtag:blogger.com,1999:blog-31189917.post-1164494659468323882006-11-25T14:44:00.000-08:002006-11-25T14:44:00.000-08:00Career-long exposure to the radiation coming from ...<I>Career-long exposure to the radiation coming from that "hot plate" (the lead-based glaze on that Fiesta ware you got in TJ that one time) cannot be healthy.</I><BR/><BR/>While some Mexican pottery glazes may contain Lead, the "red" (closer to orange) Fiestaware from Homer Laughlin Co., USA, contained Uranium Oxide. The color was discontinued in 1943 and reintroduced in 1959. <BR/><BR/>As a Chem/Physics teacher, collector of the original Fiestaware and general nuclear culture junkie, it amazes me to see product literature describe the orange as "harmlessly radioactive."Anonymousnoreply@blogger.com
