1. Based on the data, what color of light results in the fastest rate of photosynthesis? Propose an explanation for these results.
Colorless light results in the fastest rate of photosynthesis. The reason why I think this is true is because the color may slow down how many bubbles there are. If the light is colorless, the there wouldn't be anything slowing the rate of bubbles down.

2. Based on the data, what light level results in the fastest rate of photosynthesis? Propose an explanation for these results.
Light levels 8,9, and 10 produce the fastest rate of photosynthesis. The reason why is because the plant is getting more light rather than the dim light of the lower levels. Since the light is imitating the sun, then it would make sense if the higher levels of light could have a faster rate of photosynthesis.

3. Based on the data, what CO2 level results in the fastest rate of photosynthesis? Propose an explanation for these results.
CO2 Level 9.0 results in the fastest rate of photosynthesis. Plants need CO2 to photysynthesize, so the more CO2 there is, the more bubbles there are produced.

Analysis
4. Based on the simulation experiments, what factors can affect the rate of photosynthesis in a plant? How do you know?
The factors that can affect the rate of photosynthesis in a plant is light color, light intensity, and CO2 level. This is because these things are what a plant needs in order to photosynthesize.
5. Write the equation for photosynthesis (use your book or online resources if you don't know it).
CO2(gas) + 12 H2O(liquid) + photons → C6H12O6(aqueous) + 6 O2(gas) + 6 H2O(liquid) carbon dioxide + water + light energy → glucose + oxygen + water.
6. What are the bubbles you are measuring in this lab? Why do the bubbles tell you how fast photosynthesis is occurring?
The bubbles are oxygen that we are measuring. Since the plants need CO2 to create oxygen, the more bubbles there are, the faster photosynthesis is occurring.
7. Why is it important that you keep two variables constant (such as light level and color) while you're testing how a third variable (CO2 Level) affects photosynthesis?
It is important to keep two variables constant because you don't have to worry about the other two variables while testing the third. If you already know the two variables, then you would put those two on the best results in order to get the best results for the third variable.
8. What settings can you put the simulator on to get the MAXIMUM rate of photosynthesis?
Light Color: Colorless, Light Intensity: 8.0, CO2 Level 9.0.
