These fill in the blank notes with embedded CFUs(check for understanding) go along with the Energy Prezi by David Knuffke, a well known Biology teacher and Educational Consultant. I have used these notes and his Prezi's for the past 4 years I have been teaching AP Biology. Fill-in the blank notes enable students to quickly jot down the notes, providing them with more time to pay attention to the teacher's lecture.Other fill in the blank PREZI notes available for other AP Units...just ask !
