The Yeast Observation Kit includes: Fleischmann’s® Dry Baker’s Yeast 30 Balloons Sugar 30 Test Tubes 30 Pipets Autoclave Disposal Bag

Beginning - Easy to perform; requires no experience in microbiology.

For a class of 30. Students learn that yeast have many uses in our everyday lives, including the baking of bread and the production of alcoholic beverages.

They observe the process by which these simple microorganisms produce energy from an ordinary item such as sugar. As the yeast cells feed on the sugar, carbon dioxide gas is released as a waste by-product. Students observe the production of carbon dioxide by watching a balloon expand as it traps gas.

When the balloon is removed from the test tube, students can smell the yeast container for the distinct odor of alcohol. Exercise can be completed in one class period. With teacher instructions.

/!\ WARNING: CHOKING HAZARD--Children under 8 yrs. Can choke of suffocate on underinflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once.
