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...

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...

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...

Measuring Temperature and the Production of CO2 in Yeast
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...

Cell Energy - Bubbling Yeast
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...

Barf Bag Microbiology
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.
