The pages listed here are the works of other educators, learners, and chemists throughout the Internet. I have used each of these resources before and can recommend each, but your mileage may vary.

First Year Teachers (or teachers struggling with curriculum), START HERE:
Steve Marsden’s Chemistry Resources for Teachers and Students – Steve Marsden has been hosting online web resources for Chemistry teachers and students for 16 years, and they are quite helpful for planning a course. Lectures, student notes, labs, everything. It’s constantly updated, despite does look a bit outmoded. Also, read his page on the free use of the site.
Mr. Guch’s Cavalcade o’ Chemistry – Mr. Ian Guch, a high school chemistry teacher and author, has put a fair amount of his own lessons and work up on his personal site. Most useful to first year teachers might be this activity guide for beginning teachers (note – this link opens a .pdf file from another site), complete with teacher and student sections and helpful tips like “keep a toothbrush in your desk!”
Speaking of Mr. Guch, he also is working on a free online chemistry book for high school, which is pretty much awesome. Not as polished as the big textbooks, but much more direct. Which mean less confusing for students. Which is a very good thing.
Periodic Tables and Periodicity Resources:
Online Database of Periodic Tables – A couple hundred-plus Periodic Tables, spanning from antiquity to cutting edge, and including a few dozen non-chemical Periodic Tables (Beer? Blues? Baseball? Sure, why not). This is clearly a work of love.
Printable Periodic Tables – Some truly fantastic Periodic Tables designed for printing via the .pdf format. Most are Common Copyright (i.e. fine to use in class), and some are scalable to be printed at high resolution to fill a wall! Great, great resource.
Periodic Table of Videos - The University of Nottingham’s wonderful (and slightly strange) exploration of the Periodic Table in video form, one element at a time. In my undergrad Physical Chem I class (Chem 238), we would watch one video every other class or so if the lecture ended early, and we loved it.
Oakland Schools (Michigan) Periodicity Unity – (Note – this takes you to a .pdf on another site) This unit for periodicity is in-depth, organized, and very useful. Comes with several well-planned activities for the classroom, including the oft-used “Chemistry Spy” worksheet.
Chemistry Lessons and Labs
The Kahn Academy (Chemistry) - The brainchild of Salman Khan, the Khan Academy is a video-based online learning program designed to take the lectures out of the classroom and replace that time with more one-on-one learning. In practice, I’ve found this works mainly for self-motivated learners who will take the time to watch and parse the videos, but they are good, short lectures for reinforcing concepts in the classroom as well.
The SMILE Program’s Lesson Index - Nearly 200 lesson plans for individual concepts, free to use in the classroom (each is copyright of the author). Hosted by the fine folks over at the Illinois Institute of Technology.
The Royal Chemical Society Learning Portal: including Resources for Teachers and Resources for Learners – Want more practice, guides, or tools to help learn/teach chemistry? Well, the RSC is one of the best funded and most highly regarded institutions in the science. They know what’s up. This portal is a well maintained, up-to-date, and easily navigated website with tons of innovative learning and teaching tools for all levels. Students can use it to extend their learning, and teachers can use it to differentiate instruction with further practice of various levels.
Repository of Educational Videos and Animations (arranged by lesson) – A well organized collection of videos, animations, and demonstrations, grouped by unit (and subdivided by subunit). Meant to by used in conjunction with a specific program, which can be purchased (more info here), but many of the videos are excellent for any classroom or independent learner.
Chemistry on About.com – I’ve had a love/hate relationship with About.com over the years, but the current iteration of its chemistry section is well maintained and useful for finding quick demos or fun labs for the classroom. Not the easiest to navigate, but loads of articles and info. They also have a list of activities and labs, but these are more “How-To” and need to be edited for use in classroom.
Database of Chemistry Databases and Simulations - A decent, well-maintained source to investigate if you didn’t find what you needed here. It does seem a bit hodgepodge, but there are a lot of good resources listed.
