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...

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Don't let your bacteria go to waste. A tutorial explains how to properly store and maintain bacterial stock cultures. It describes the purpose and preparation of a permanent stock, as well as a working stock for use in experiments.

Cultivate bacteria with a straightforward lesson featuring agar. Scholars create a streak plate on agar to ideally create colonies of bacteria or yeast that are growing separately from each other. The resource introduces the simplest...

What makes sourdough bread different from other types of bread? An installment of a PBS food science video series explains the science behind fermentation, yeast, bacteria, and their relationship with sourdough bread. It also discusses...

Breathe a sigh of relief! Life science scholars experiment with yeast to uncover the facts about respiration. The instructional activity guides them through the purpose of respiration and its relationship with photosynthesis. Individuals...

Scholars harness the power of microbes with an engaging activity that uses yeast to break down sugar in water. Multiple setups of the same experiment lets learners determine which temperature results in the fastest rate of sugar...

While the bad bacteria get most of our attention and research into antibiotics, the good bacteria is also important to your health. Explain the different types of bacteria with an illustrative video. 

The gourmands and foodies in your class will love this gastronomical video! Educational and entertaining, the video explains the natural and added microorganisms that occur with food production, including yeast in bread, carbonation in...

Students explore DNA. They work in groups and mix prepared detergent/ salt solution, meat tenderizer solution, Fleischman's yeast and water to extract DNA from yeast. Observations are recorded.

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

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...

Students design an investigation using yeast. For this environmental engineering lesson, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative data and discuss...

Introduce life science students to their new "best buds" yeast! Using a wide variety of materials, lab groups design an experiment that illustrates how yeast acquires the resources it needs to undergo cellular respiration. The teacher's...

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...

Though it states that it is a learning exercise, this technically is a set of directions for a series of six activities exploring physical and chemical changes. Chemistry or introductory physical science aces examine carbon dioxide...

Students use a model experiment to complete an experiment on yeast. In groups, they identify the independent and dependent variables and use the scientific method to complete the activity. They record their observations and discuss them...

New ReviewGet a surprised reaction from trying out the chemical reaction. Scholars conduct a chemical experiment by adding yeast to hydrogen peroxide and dish soap in a plastic bottle. They learn that yeast contains a catalase enzyme that releases...

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...

Students explore what causes bread to rise and how fungus is found in many forms. In this fungus lesson students complete a yeast lab and discuss what happened.

Learners create a KWL chart about food. For this chemistry lesson, students differentiate physical and chemical changes. They explain how microorganisms are used in food preparation.

Learners 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.

In this alcohol fermentation activity, students design an apparatus to study the alcoholic fermentation of yeast. Once complete, students answer 8 short answer questions.
