Science Buddies: Yeast Reproduction in Sugar Substitutes
There's nothing quite like the smell of fresh-baked bread to make your mouth water. As any baker can tell you, you can't bake bread without yeast. This project makes clever use of bread dough to measure yeast reproduction three different...

Microbes in Action: Classroom Activities: A Swell Lab: Yeast Fermentation [Pdf]
This two-day experiment uses different concentrations of sugar to study the rate of fermentation. Students observe the rate of carbon dioxide gas produced by yeast to infer the rate of fermentation. Lesson plan gives a lab procedure,...

Teach Engineering: Sugar Spill!
In this activity, students act as environmental engineers involved with the clean up of a toxic spill. Using bioremediation as the process, students select which bacteria they will use to eat up the pollutant spilled. Students learn how...

Bio Ed Online: Fuel for Living Things
Students learn about how cells fuel themselves by examining how carbon dioxide is produced by yeast cells when the cells feed on sugar. The carbon dioxide is detected through the use of a red cabbage indicator that reacts in the presence...

Teach Engineering: Microbes Know How to Work!
Students design systems that use microbes to break down a water pollutant (in this case, sugar). They explore how temperature affects the rate of pollutant decomposition.
