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...

Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow.

This is a straightforward project on glucose metabolism in yeast. You'll grow yeast under aerobic and anaerobic conditions and measure carbon dioxide output to assess metabolic efficiency.

Using grape juice as the yeast's food, this lab experiment allows students to test the effect of temperature on yeast fermentation.

Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second,...

In this lesson plan students will observe the growth of yeast cells, which is evidence that yeasts are converting food to energy and are living organisms.

In this classroom lab experiment, students measure the effects of temperature on yeast growth and reproduction.

In this classroom lab experiment students measure progress of sugar fermentation by yeast using a hydrometer.

Brief text summary of what students learn in the Is Yeast Alive? Lab, along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Characteristics of life are addressed and metabolism and the...

This activity is the second of two that explore cellular respiration and population growth in yeasts. In the first activity, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in...

In this biotechnology science fair project, investigate how DNA damage affects growth of yeast that are DNA-repair deficient. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

Gives a procedure for observing the creation of carbon dioxide by active yeast. Following the procedure, a brief description of how yeast is used in bread is presented.

Discusses the characteristics of mold and yeast and how they are different in terms of structure, where they are found, method of reproduction, and appearance.

A text summary of what students learn in the Alcoholic Fermentation in Yeast lab, along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Aerobic cellular respiration and alcoholic fermentation...

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,...

In this classroom lab experiment, students mimic optimal growth conditions for yeast, and with the help of a microscope, observe and record results using a cell counting method.

Learn about the structure, size, and uses for yeast in this reference article.

Students set up and run the experiments they designed in the lesson Population Growth in Yeasts, using simple yeast-molasses cultures in test tubes. Population growth is indicated by the amount of respiration occurring in the cultures,...

While looking at a package of dry yeast it is hard to believe it is alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life. What are the right ingredients? Do this experiment and figure it out...

Young scholars 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...

Two lessons and their associated activities explore cellular respiration and population growth in yeasts. Yeast cells are readily obtained and behave predictably, so they are very appropriate to use in middle school classrooms. In the...

Students are presented with information that will allow them to recognize that yeasts are unicellular organisms that are useful to humans. In fact, their usefulness is derived from the contrast between the way yeast cells and human cells...

Article takes a look at how unicellular organisms "chat" with one another using chemical signals. It examines yeast mating types, bacterial quorum sensing, and biofilms.

Understand living and non-living things by investigating yeast.
