I appreciated reading this post because I have recently been thinking about suggesting that the chemistry course at my school be separated into subsections such as those that you mentioned: conceptual, regular (math-based), and honors. At my school, it's either regular or honors. Currently, I am in the process of teaching avo's #, molar mass, mole ratios and stoichiometry and the delineation betwe...

Chris, u seem very passionate, however, I always know my audience. I think Pam and I are passionate about the potential for conveying MISCONCEPTIONS however inadvertently and I agree with you and Pam. The original post asked for, "cut & paste S, P, D, F electron orbital activity." I believe that sparked the concern and understand why. Just to be consistent in avoiding misconceptions: orbit...

I think I understand Pam's concern about the probability of the location of electrons in atomic "orbitals". I have wondered myself about the concreteness of the activity that I use to have students represent the distribution of electrons in orbitals and the impression that it leaves on them. That being the case, I limit it to a simple type of "orbital structure" just before Lewis dot structures. S...

5 Atomic Structure & Bonding: Excellent Resource
This Sci Guide is divided into three themes: Interactions, Descriptions and Classification of matter. The themes are further divided into subtopics and there are a large number of links in this guide. The most interesting of the resources to me are the vignettes. I find these to be like little gems for delivery of instruction that incorporates student-centered and problem-based learning. Under all themes there are lesson plans, vignettes, audio/video clips, and more. Links are provided for virtually everything from the simplest of chemical reactions to nuclear reactions. I found this Sci Guide to be very useful because the vignettes provide the opportunity for inquiry-based as well as student-centered and problem-based learning.
