Experiment #1 (temperature):
Though are results may not have been completely accurate due to excess oxygen from air bubbles and the buckets of samples sitting out for a period of time, much can still be said about our results.
-While testing the canal and beach water at different temperatures, we found that the average percent saturation of the cold canal water was 10.3%. This was significantly higher than the canal water at average temperature with an average percent saturation of 9%. Results were similar for the different beach temperatures. The iced beach water had an average percent saturation of 9%. The beach water at average temperature was 8%, which is also much less than the cold water. This shows that cold water is beneficial for water because it is able to hold a greater amount of dissolved oxygen.
Experiment #2 (light):
-For the screen experiment, the results showed that as you add more screens to the water samples, the amount of dissolved oxygen decreases. This shows the importance of sunlight to water because without the proper amount of sunlight, plants can’t perform photosynthesis, which limits the amount of oxygen released as a byproduct.
Vernier Probes:
-Overall, the pond, beach, and canal samples had fairly close dissolved oxygen levels at around 12.9 mg/L. The canal water did vary slightly with 12.7 mg/L. In addition, the carbon dioxide levels were fairly similar as well with the beach water having a slightly higher level. This shows that the amount of respiration releasing carbon dioxide and the amount of photosynthesis occurring in each sample are fairly similar.
Diversity of Organisms:
-We did find around 2 species of organisms in each sample which makes sense because the amount of carbon dioxide due to the respiration of organisms is about the same in all of the samples.
