If you're a new teacher who needs ideas, or an old teacher who wants to try something new, you may be interested in my complete set of chemistry resources. Included in this package are the following:
1) My complete lecture notes for general and honors level chemistry
2) Many worksheets to support the information in this package
3) Labs, labs, labs!
4) Discovery activities that actually work
5) Quizzes and tests to assess student performance.
I have worked in chemistry education for a long time and written several books on the subject ("The Complete Idiot's Guide To Chemistry" by Alpha/Penguin as well as some other lab books) and want you to know that these are the very same resources I use with my own classes. Though designed for high school chemistry classes, I've gotten great feedback from physical science teachers indicating that it works well for them, too.
You may occasionally find an error here or there or find that a worksheet may not have an answer key (I don't always have one), but overall I think you'll agree that $19.95 is more than fair for this great big bunch of chemistry goodies!
