This is a 12-slide PPT used as an introduction to the nervous system. It is visually stimulating with lots of full-color clip art and interesting facts. There are lots of questioning opportunities for the teacher to present to the class while showing this ppt, which can open up further class discussions. After I show a ppt, I always have a graded assignment based on the ppt to ensure class paticipation. I have an assignment in my store titled "Intro to the Nervous System PPT Worksheet with KEY" which is available for $4.00.
