Biofuels provide an alternative to petroleum-based fuels. Ethanol, a biofuel produced from biomass such as corn, is frequently blended with gasoline to produce a “cleaner” burning fuel. In this lab, students explore ethanol production through the fermentation of carbohydrates by yeast cells. The lab begins with an introductory activity in which students conduct a controlled experiment to investigate the amount of carbon dioxide produced through the fermentation reaction of yeast with two different types of carbohydrates. Students observe the amount of carbon dioxide produced and determine the most productive carbohydrate food source. Then students are then challenged to design and implement a method to collect and quantify the amount of carbon dioxide produced. Integrate scientific inquiry and engineering design and their application to human challenges in our world with this engaging activity. Complete for 30 students working in groups of three.
