How Does Temperature Affect The Rate Of Photosynthesis

Methods We began this experiment by turning the Spectrophotometer to 605 nm absorbance, and setting up each of the tubes as stated in Table 7-2*, ignoring the DPIP until the rest of the sample was set up. Once all of the samples were set up accordingly, we blanked the spectrophotometer, and added the DPIP to the sample right before, inverting the sample and taking a reading at the Zero time mark, and placing the sample in the designated light apparatus, Sample 1 was wrapped in aluminum foil to keep it in the dark, Sample 2 was placed 24 cm from a light source, Sample 3 was placed 30 cm from a light source, Sample 4 was placed 49 cm from a light source, and the Blank was left out to be exposed to the light in the room. Every 5 minutes, we blanked the spectrophotometer, inverted the samples and took a reading from each of the samples, recorded in Table 7-3*, replacing each of the samples into its apparatus when done with the reading. There were two separate experiments going, and the data shown has both results as well as an average.
Hypothesis
Due to the fact that it would be closer to the light source, the light would be slightly more intense, therefore the rate of photosynthesis would be slightly more advanced, causing a lower absorption. I also believed that Sample 1 the sample wrapped in aluminum would have the highest absorbance due to a lack of
