Fermentation in a Bag

|
Ask a Question

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 COor ethanol.
Teaching Tips

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.
Scientist Notes
This resource from The Wisconsin Energy Institute, the "Fermentation in a Bag" activity, is a hands-on experiment, and can be adapted for various grade levels to compare fermentation levels in feedstocks, which could be converted into biofuels. Additional resources are available to extend learning in the field of fermentation. This resource is recommended for teaching.
