Interactive Fermentation Lab

Investigate how yeast ferments sugar to produce carbon dioxide and ethanol. Collect simulated data and analyse fermentation activity.

Student Information

Lab Focus

Aim: To investigate fermentation in yeast by measuring carbon dioxide production.

Background: Yeast is a microorganism that can respire anaerobically. When oxygen is limited, yeast breaks down glucose and produces ethanol and carbon dioxide.

Glucose → Ethanol + Carbon dioxide + Energy

Student view: results only Teacher view: hidden conditions Master Sheet: full data

Safety Notes

  • Wear goggles if using real yeast and warm water.
  • Do not drink the yeast-sugar mixture.
  • Use warm water, not boiling water.
  • Clean spills immediately.
Reminder: This version uses a simulation, but the same scientific reasoning applies to a practical lab.
