Great job. The reason the water disks rose is because oxygen is produced as a by-product of the light reactions not Calvin Cycle. There is no relationship between CO2 and Oxygen. The process is called photolyis. The main purpose of the LR is to create the energy source (ETC) to build sugar in the Calvin Cycle. This is why water is so important for plants. PLUS they have to respire as well. Great job.
