A clearer plan would also have been useful. We found that one group sampled each area three times while the other group sampled only one time. This miscommunication demonstrates how clarifying a project design is a critical component of research. Also, our method for measuring salinity may not have been consistent. Samples of water were taken at different levels.
Saltwater is denser than freshwater and therefore settles at a lower level than freshwater.
If our salinity measurements were to be accurate we would need to measure at the same depth for each sample. Our reason for doing this project is we care.
