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.

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...

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...

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...

Young scholars 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...

Students investigate and determine which types of carbohydrates Baker's yeast prefers. They crumble Cheerios, Smarties, and Fruit Loops and feed them to the yeast and watch what happens, when the bags begin to barf.

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 comprehensive exhibit focuses on the wonders of microorganisms, what they are, how they can affect our daily lives, and how they can be manipulated. Videos, games, and animations are included. Teacher resource link explains each...

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...
