Fermentation Challenge: Making Ethanol from Cellulose

Type of Resource



This hands-on activity introduces students to the process of fermenting different carbohydrate sources into ethanol. Teachers demonstrate yeasts’ inability to metabolize certain food sources.

Performance Expectations

HS-LS2-3   Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.

HS-LS2-7   Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.

HS-ETS1-2   Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
