Synopsis
- In this experiment, students will create ethanol through fermentation using a few common ingredients.
- Students will use warm water, dry active yeast, and feedstock to create ethanol and CO2 in a bag and measure the production of gas and ethanol using various tools.
- Students can also compare which feedstocks produce more CO2 or ethanol.

Teaching Materials
Positives
- A video and written instructions make it easy for teachers and students to understand the experiment.
- This resource contains a video on measuring fermentation rates without an ethanol probe, allowing many classrooms to perform the activity with few resources.
Additional Prerequisites
- This experiment can be extended into a complete lesson on biofuels using the resources at the bottom of the page.
- Students should know what ethanol is and its uses.
- It may benefit students to first learn about chemical and physical changes.
Differentiation
- Before beginning the experiment, the teacher can engage students and assess prior knowledge by reviewing chemical reactions.
- This experiment can fit within a larger unit on different types of alternative energy.
- This experiment can supplement a classroom discussion on new research related to corn-based ethanol or waste-based biofuels and their economic or environmental aspects.
