This lesson functions best at the onset of teaching cellular respiration. These guided notes may be used as a lecture aid, reading guide, or review tool. I use them as a viewing guide for Bozeman Biology Cellular Respiration which can be found at the following web address http://www.bozemanscience.com/cellular-respiration/. AP students are generally advanced learners, but the language used in cellular respiration can be daunting. These notes are a great way to keep students engaged, without leading them to a sense of helplessness when they are not able to keep up.
The video is about 15 minutes long, but I choose to pause it intermittently to check for understanding or remind students or prior learning. These notes could also serve as a stand-alone homework assignment to front load information for an activity the following day.
