Taylor Newcome- Meaning of Data
The meaning of data is, how good or bad your results are and what effects come from those results. Our class went to Cloe Lake and we did tests on the water. Due to the fact that it rained high amounts the night before some of these numbers could be slightly off. We have two people working on this part of the paper, i am only going to share half of the results with you where as my partner will share the other half. Our group did two test on pH our first result was 6.9 and our second was 6.4. As you can see from this picture that is normal due to the amount of rain the river obtained. Our next test was total alkalinity, is a measure of the ability of a solution to neutralize acids to the equivalence point of carbonate or bicarbonate. When we did this (you can look at the procedure page to see how) our first result was 37 and our second result was 0. These are two totally different numbers! The second group also said they messed up though. I am going to go with the first number then which means, There are some chemicals in Cloe Lake. Bigger Lakes and rivers have higher alkalinity. This is a little higher than usual at Cloe Lake though. Our Third test was iron. When you find how much iron is in water. Iron water has calcium, magnesium, and iron in it. For our results we got 0.5 and 0.5. Both groups did the test accurately and got the same thing. These results are a little high they should have been between. 0.1 and 0.3. This is not harmful or extreme but it is high.

Sydney Phillips- Meaning of Data
As Taylor said, her and I both are doing half of the data. Some other chemical tests that we were able to do were the hardness of water, the turbidity, and the nitrate levels. When we did the test for hardness we only had one result and it was 200. This was a normal amount of hardness that Cloe should have. We tested the hardness of the water because if the water is to soft, fish and critters could die to low levels of not enough chemicals, and if the water is to hard; that could lead to high levels of chemicals that should not be there.

With the turbidity we were able to get two results; 2, and 1.5. Finding the turbidity means that we were finding if there were high/low levels of clearness. We found that both of the results were around normal levels that it should be. Though, it rained quite a bit and our group feels the results could be just a little bit higher than it was.

With the results of nitrate (Ni-N) we were only able to get 8.8 as our result. What we found was that it was normal, but almost hitting the high mark. For finding the nitrate, that just means that we tested to see if to much bacteria, pollution, plant growth, etc.. was developing in the lake. If so there were high levels then that means that if they would die, everything would die in that group and would take oxygen from the lake; which is not good. If not enough levels, there would still not have enough oxygen.

For the dissolved oxygen (DO) we had some trouble with the testing. We were only able to get one result due to the other group messing up, and having problems. For the DO we got 15. Dissolved oxygen is just finding the amount of oxygen levels. What we found was that 15 was a pretty high number of DO. Normal would be between 4 and 10.
