This is two powerpoint presentations. It includes a student version and a teacher version. The student version is first in the line-up, but you can start the presentation wherever you need to do so. There are a lot of pictures, and you can print the student version so that students can take notes on it. It has fill in the blank for the students, but it is minimal enough so that you can cover the information quickly, however it requires students to stay on task and pay attention to the slides. You could also break it up into more than one class period as needed.
110 (55 for student version and 55 for teacher version)
