Is Yeast Alive?
Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Alcoholic Fermentation in Yeast
Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...
Curated OER
Yeast
Students study the characteristics of yeasts. In this biology lesson, students conduct experiments to measure yeast respiration. They discuss the favorable conditions needed for growing them.
Curated OER
Yeasts and Molds
Learners investigate the characteristics and nature of yeast and molds help to explain how these microorganisms affect food production. They experiment with yeast in sourdough in preparing sourdough pancakes.

Cell Energy - Bubbling Yeast
Students identify that yeast are a single celled fungi that are a great model organism for studying respiration in the classroom. They also fill the bulb of a disposable pipet (eyedropper) with yeast, then submerge the pipet in a test...
Curated OER
Microbes
Microbiology beginners feed different sweetening agents to yeast and measure carbon dioxide production to estimate energy contained in each. They set the trials up in zip-top plastic baggies and then measure gas volume by water...

Experimenting with Yeast Metabolism
Ninth graders determine the rate of respiration by yeast and which sugars can be used as a food source by yeast using a CO2 gas sensor and computer software. This lesson plan is for an honors Biology class.
Curated OER
Yeast Power!
Students examine how not all microorganisms are bad and that some can actually be beneficial. In this yeast lesson students complete an experiment with yeast and answer questions.
Curated OER
Breathing Yeasties
Students show how microorganisms and the carbon cycle interact. In this microorganisms lesson plan, students show this by using yeast, sugar, and water, and observe the energy flow.
Curated OER
Yeast Blowup
Students experiment to determine if yeast is a microorganism. In this yeast blowup lesson, students mix yeast with other ingredients and observe the results by using a balloon. Students adjust the amounts of the ingredients and test...

Yeast Bread - Pretzel Lab
Students work with yeast in preparing soft pretzels. They identify the characteristics and ingredients used in yeast breads from quick breads, and how to prepare them in a variety of recipes. They set their table, eat and clean up...

"The Yeast of Our Worries"
Students study yeasts or cellular respiration in this inquiry activity. They examine different types of bread to show which rise or do not. They measure the amount of carbon dioxide released by the yeasts when using different sweeteners.
Curated OER
Microorganism Multiplication
Sixth graders conduct experiments with yeast to study characteristics of microorganisms. They, working is small groups, change the variables in the experiments and note the results which they later discuss as a class.

Yo! Gert-making yogurt
Young scientists or chefs culture yeast to produce yogurt. The materials and a general description of how make yogurt are provided, but there is very little detail otherwise. You could use this as an activity when your biology class is...
Curated OER
Yeast and Respiration
Students explore oxygen properties by conducting a cell experiment in class. In this respiration lesson plan, students discuss the process of breathing and how oxygen is inhaled before carbon dioxide is exhaled. Students utilize yeast,...
Curated OER
Yeast Cells and Their Environment
Students create their own experiment in which they have yeast cells growing in liquid environments. They examine the relationship between humans and microorganisms. They also practice using the scientific method.
Curated OER
Yeasts and Molds: Food Science, Bacteria, Fungi
For this lesson students will consider the characteristics and nature of yeast and molds in order to help them understand how these microorganisms affect food production.

No Fossils in This Fuel
Yeast and sugar go beyond the pantry and into a fuel experiment. Use these common baking ingredients to assist your class in creating ethanol, a natural fuel. Pupils observe the process and gather information to elaborate...
Curated OER
Yeast Fermentation
Students measure the temperature change involved in the production of carbon dioxide by yeast. They also identify products and reactants in a chemical and balance the equation.
Curated OER
Planets in a Bottle
Students experiment with yeast. For this environmental conditions lesson students test the viability of samples of yeast. Students investigate the effects of environmental conditions on the yeast.
Baylor College
Fuel for Living Things
During a three-part lesson plan, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which...
