They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. As oxygen is produced, the density of the leaves change and they will begin floating in a sodium bicarbonate solution. The time it takes for a certain number of leaves to float can be used to calculate the rate In this walkthrough we will be going over activities A, B and C. For comparison purposes, each lab group that does this procedure should report the time at which half (5) of the disks is floating. Then you will create your own investigation to test the effects of a second variable on the rate of photosynthesis. And we animals repay the favor: We exhale the carbon dioxide that plants need for photosynthesis. In cellular respiration, living things use sugar to produce energy.
