Sample Location: discovery and san marcos blvd. Medication: Calcium Carbonate (tums) .76g- .3g Observations: From what I saw in my observations a large of the majority of the tests were effective in making the daphnia survival rate higher than any of the other experiments done because the calcium carbonate did not seem to have a severe effect on the daphnia till the second round of dosage. I even found a pod looking object that was in the water that I later found out was an egg. After a day or two I found out that it might of hatched (most likely because I could not find it within the sample). I saw that some of the Daphnia that died were adult and less of juvenile. When the behavior of the Daphnia before it died was a very rapid heart beat, then it would float around a little bit with a much slower heart beat for even it's average beat before in contact with the medication. For visual representation of data found click here. PIctures here: 2 Analysis: I believe, in analysis, that the medication was not consistently harmful to the daphnia. The tums would make the water partly more cloudy because of all the chunks from the powder but the daphnia would not choke on it as much as the last medication given to them. This medication, in conclusion was survivable in and in less of an effect to the Daphnia, letting them still have the ability to reproduce.
