If you are a student in one of my classes you will find material that is supplementary, not essential. If you want to know more about a topic we have discussed--or want a different perspective--try the Topics section. On those same pages you will find supplementary practice problems as well. The online "lectures" approximate what might go on in class on a good day :-). If you're absent or need a quick review, that's the place to go. Since this site is always under development, feel free to let me know if there is something else you would find helpful here. You can either tell me in class or e-mail me here. If you have questions that for some reason or other you didn't ask in class, you can also e-mail those. E-mail of a personal nature will be held in confidence to the extent that my professional responsibilities allow (translation: if you tell me you just hacked a neighbor to pieces I'm not going to be able to keep that under my hat!). I generally check my mail daily.
If you are a chemistry student at some other school, you are especially welcome! Let me know how you found me. If you have questions of a chemical nature on which you'd like another perspective, send them my way. I can't guarantee to know the answers, but I'll try to point you in the right direction. If you have suggestions for this site or interesting links, please feel free to send those also.
If you are a chemistry teacher I hope that you will find some things of value here and that you will also contribute helpful ideas, interesting links (and maybe even give me a little encouragement!). If a particular experiment interests you prep sheets with solution directions are available for the asking. If you see an experiment and say to yourself: "why in the world is he doing that?" or doing it "that way?", I would appreciate your input. In addition to the experiments I use in my courses I have tried to find other experiments around the Web since I am always looking for new ideas. You will find some links to these other experiments in the Labs section and in the individual topic units of Topics.
You will not find A.P. or other exam material here. I do not believe it is appropriate to post those materials because I know many of my colleagues use some of the questions in their own classes for evaluation purposes. There are also legal issues involving copyright. If you need some back copies of A.P. exams or scoring standards, I would be happy to share from my files, but you will need to send me a request on school letterhead via snail mail.
A word about "FAIR USE": You are welcome to use any materials I have created and posted. That's why they are here, after all. I'm not particularly concerned whether you acknowledge me as author or not. I am not under the illusion that I have a viable commercial property here.
BUT, you should not "borrow" any part of the site design (as has been done with the Periodic Table). However uninspired it may appear, it took me a long time to get here and I'm partial to my years of trial and error.
ALSO, you should not republish my work in any form. There is no need to since it is all freely available here. In particular you should NOT republish my materials and claim they are your own, as has been done elsewhere (compare here vs. here, or here vs. here, or here vs. here.....etc., ad nauseum....). Our students deserve a better example.
