Quizlet: An MIT freshman created a great tool for making online flashcards and using them to quiz yourself (and your friends). The site also includes flashcards other people have made. I recommend starting with the Video Tour.

Mole Cartoons. Feel free to use these mole cartoons drawn by me and my daughter, Sarah. I used to paste them in the margins of my fall exam.

demo Demonstrations. Here's the link to a page listing many of my favorite Chemistry demonstrations.
