One of the end products of respiration is carbon dioxide, or CO2. In this activity, you’ll measure the amount of CO2 yeast produces when it is fermented in five different cups with the following contents:
Cup A: yeast and lukewarm water
Cup B: yeast, sugar, and lukewarm water
Cup C: yeast, sugar, and hot water
Cup D: yeast, sugar, and cold water
Cup E: yeast, sugar, and lukewarm water (covered with plastic wrap)
You’ll use a ruler to measure the amount of CO2, or foam, that forms in each cup. Do you think the amount of foam in the cups will differ? Write down your prediction.
