I have gone back over my previous postings and added PowerPoint files, Learning Guides and Labs for each week. I handout the learning guides to the students and they are supposed to fill them out as I lecture. The idea is to emphasize the key points and keep their interest level up. I removed any pictures from the PowerPoint files that I did not have copyrights to. You may want to spice them up with some of your own pictures. The pictures I included are my own.
