Wow, the human body is complex! The video explores the importance of oxygen, beginning with exploring why it is needed in combustion and then moving into an organism's need for oxygen. Learners see how glucose, when combined with oxygen, transfers electrons to the oxygen, releasing potential energy to make ATP.

Instructional Ideas

• Briefly review potential energy, protons, electrons, and ions before showing the video

Classroom Considerations

• Classroom should have a computer, Internet access, and a projection system to show the video
• Assumes learners understand potential energy, electrons, protons, and ions
• The lesson is part 34 in a series of 37

Pros

• Contains a great visual of electron transport chain inside the mitochondria
• Provides a simple and effective description of how ATP isn't energy but releases potential energy when converted to ADP and a phosphate
• Awesome visual showing what would happen in electron transport chain without oxygen present

Cons

• None
