In this cell respiration lab, students will learn about anaerobic alcoholic fermentation and how the the amount of carbon dioxide produced by yeast during cellular respiration is affected by the temperature of the yeast’s environment. This cell respiration and fermentation lab is sure to be a hit in your secondary science classroom!
This lab includes an editable version, digital version, full lesson plan, rubric, and more! Students will use balloons, yeast, sugar, and water to compare the rate of alcoholic fermentation in room temperature and warm conditions.
First students will read a background reading about yeast and cell respiration. Students will then experiment, collect, and analyze data on how temperature affects anaerobic cellular fermentation. They will study yeast and a sugar solution in a closed system (balloon and container) and measure the amount of carbon dioxide released during cellular respiration. Students will compare the difference in rate and release between two different environments (hot water bath versus room temperature water).
The lab student handout consists of background reading, pre-lab questions, hypothesis making, variable and control identification, data tables, graphing, and analysis and conclusion questions.
All materials are listed in this product’s preview and are easily accessible to most science labs. Only a grocery store trip is needed in case you don’t have these materials in stock.
