Yeast Cells and Their Environment

Can microorganisms live in the dry, cold climate of Antarctica? Young scientists view a research project measuring microorganisms in the Taylor Glacier. They record the findings from dirty ice, clean ice, boots, sediment, and more. Then...

Following directions from a colorful slide preparation card, beginning biologists examine three different live microorganisms: bacteria, yeast, and paramecia. This is not an unusual activity to do with your class, but if you are doing it...

Students examine cell division and the process of mitosis.  For this cell reproduction lesson students grow yeast and observe the results, and learn about the career of scientific illustration. 

Student observe and quantify the respiration that occurs in yeast-molasses cultures. They complete an effective experiment in order to examine how to think critically about the results.

Middle schoolers build an apparatus to look at how yeast cells grow by converting food to energy. They observe yeast both with and without food and see how yeast produces carbon dioxide.

Beginning biologists prepare a sugar solution for yeast cells to live in, and divide it into two different jars. Samples from each jar are viewed with a microscope, and then one jar is placed in a warm environment and the other a cold...

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.

Students 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.

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

Students correlate a series of items with the organelles of a cell. They compare the school to a cell, and create a drawing that compares the cell structure with their home.
