Modeling Cellular Respiration: How is the Mitochondrion the "Powerhouse" of the Eukaryotic Cell?

This is best for high school AP/IB/Honors Biology students for using clay and miscellaneous items to model and then film their model of Cellular Respiration to better understand how the Electron Transport Chain generates energy in the form of a proton gradient that allows for simple diffusion of those protons through ATP Synthase which turns and attaches a phosphate group to ADP thus creating ATP, the chemical "power" of cells.
