Energy For Life

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source. Learners will make predictions, conduct the experiment, record observations, create a bar graph to chart the results, and draw conclusions about the role of sugar as an energy source. If thermometers or probes are available, learners can also measure temperature to explore heat as a by-product of energy conversion. This guide includes background information, setup and management tips, information about using cooperative groups, extensions, and a handout.
