WebPlace one set of respirometers into the room temperature water bath and the other set in the ice water bath. Elevate the respirometers by setting the pipettes onto masking tape and allow them to equilibrate for five minutes. Next, lower the respirometers into the water baths and take reading at 0, 5, 10, 15, and 20 minutes. WebAs water is transpired from the leaves, the shoot absorbs water from the potometer. The distance the air bubble moves in a certain period of time can be used to calculate the rate of water... WebFigure 1. Preparation of respirometers. 4. We will let the yeast incubate 10 to 20 minutes. If yeast are producing carbon dioxide, what should happen to the bubble? _____ 5. So our dependent variable is the change in bubble length, that is, the difference in bubble length before and after incubating the respirometers.. As a group or as a class ... dana mathewson parents
