Bubbles are given off by the plant through photosynthesis. By measuring the rate at which the bubbles are produced it is possible to tell how fast the plant is photosynthesizing. Read and follow the directions on how to use this lab simulator. Press start and record the bubbles per minute for each of the following light distances. Then graph your data. Be sure to label the axes, give units, use appropriate intervals, and give a descriptive title. As we are not writing a scientific paper you don't need to do in replicates.
HINT: Start with 200 to get the hang of counting the bubbles.
Results:
Title: Title should reflect what is shown, it should be self-explanatory, it should be clear and easy to read.

Data collected must be graphed using a graph paper. Graph must be properly titled and X-axis and Y-axis must be labeled. Title of the figure should reflect what is shown in the table, it should be self-explanatory, it should be clear and easy to read.
Figure title and number must be below the figure.

Based on your results, explain how light intensity affects the rate of photosynthesis. Use your data to help explain your answer.
Based on the data, the lowering of the light intensity results in a decreased rate of photosynthesis. In the experiment, when the the light was further away(lower intensity), the amount of the bubbles given off by the plant was smaller. The number of bubbles showed the amount of O2 gas let out by the plant, this also portrayed the rate of photosynthesis. The bigger the bubbles, meant there was a higher rate of photosynthesis. There were more bubbles produced when the light intensity was higher, which means higher light intensity results in a higher rate of photosynthesis.
