I saw them, Neal, and she will get them today. Many thanks. She's also going to become a member. Since she's also an IH that I have known for decades who is taking another career tack, she should be an interesting edition one day to this forum.

I got the following request for information and thought: Who better than you guys to answer her? Here's the question:

I have started student teaching science in middle school and next week we start chemistry. I am working on my lessons which are based on a given curriculum and chemicals we have already purchased as a school district. So I see that we are precipitating lead iodide using a lead nitrate solution which the teachers prepare and am thinking I have to find something that says we shouldn't be doing that. I will have to check the disposal laws in New Jersey. We do it in a test tube, and use about 40 test tubes . Anyway, I will do the research and check the SDS that comes with it, etc. I know it's a carcinogen.
