Brine Shrimp Project Hypothesis

Decent Essays
After analyzing the data and charting the results the conclusion is a bit inconclusive. In the first two days of exposure to the wavelengths the eggs in each group showed no signs of change. We decided to give the eggs a few days before we disturbed them again and checked them after the weekend. What we discovered then was that a varying percentage of the eggs had hatched in each of the experimental groups. The difficult part was that the individual trials that were under the same shade of light also had varying percentages of hatched eggs and there didn’t seem to be a real established pattern in the rates. Giving the specimens two more days to develop we checked them midweek. We found that out of the percentage of surviving specimens (those that actually hatched) a vast majority seemed to be thriving. However similar to the hatch rate there did not seem to be a clear trend favoring one color of light over the other. We did find that the dish deprived of light seemed to consistently have a better hatch rate as well as survival rate after birth. These finding seemed to support our original hypothesis that the colored wavelengths would negatively affect the brine shrimp development.…show more content…
These findings made it difficult to confirm or reject our original hypothesis because such a high percentage of every group had died in a matter of days. This trend included the brine shrimp deprived of light. Based on physical appearance of the few brine shrimp that lived through the third observation the group deprived of light seemed to be more active and quantitatively more than the other groups but the maturity level seemed to be less. In the colored shades the brine shrimp that lived while there were fewer seemed to have actually developed appendages and appeared to be more mature than that of the group with no
