These Powerpoint presentations were created by Benjamin W Snyder. He passionately taught a variety of college biology courses at many colleges over the past 40 years. Just to name a few; Swarthmore, Vassar, Framingham State, and WPI.
All of the Powerpoint presentations he has to date are too much to list, but these, he hopes will help teachers and students all over the world. You may download and use these as part of or entire class materials. Here are 22 powerpoints, also converted into PDF format, each one a basic biology course.
