Why do leaves change color in the fall?
The control with water took the longest time and did not have more than half of its leaf discs rise within 30 minutes.

The .4% and the .2% don't seem to be as set apart as the .6% Experiment In this experiment, disks are punched into spinach leaves and are put in solutions with either water, .2% bicarbonate, .4% bicarbonate, or .6% bicarbonate.
The experiment was prepared by streaking pigment extract to the bottom of chromatography paper and placing it in a tube with chromatography solvent in the bottom. Note the movement of the solvent up the chromatography paper (click for a larger picture):Chlorophyll b is olive green, chlorophyll a is a brighter green, xanthophyll is yellow, and carotene is a yellow-orange.

The rate of photosynthesis actually seemed to be picking up around the 9th and 10th leaf, this could mean another experiment with more than 10 leaves should follow to see how much higher the rate will increase and when it will finally start declining.
Explain. 2) What went well with the experiment? 3) What went wrong with the experiment? 4) What new problems (questions for study) arose as you did this experiment? 5) What did you learn from this experiment?

Since CO2 is essential to a plant’s ability to carry out photosynthesis, it will be the variable tested.
Using the floating disk technique in our experiment to measure the rate of photosynthesis, spinach leaves will be submerged in a concentration of CO2 and a concentration of water.
In this experiment, the leaves will only rise to the surface when enough CO2 and light is present to allow the leaf disks to carry out photosynthesis and produce O2.
