Experimenting with Yeast Metabolism
Ninth graders determine the rate of respiration by yeast and which sugars can be used as a food source by yeast using a CO2 gas sensor and computer software. This lesson is for an honors Biology class.
Curated OER
Yeast Power!
Students examine how not all microorganisms are bad and that some can actually be beneficial. In this yeast lesson students complete an experiment with yeast and answer questions.
