Investigate one of biotechnology's earliest applications

Study the fascinating world of fermentation, the chemical process whereby microorganisms - such as bacteria, molds and yeasts - break down energy-rich, organic materials into various by-products. Your class will distinguish between aerobic and anaerobic respiration and calculate the volume of carbon dioxide gas produced under various conditions. They'll also determine how the yeast's growing conditions relate to carbon dioxide production and what growth conditions are ideal.
