We see a pattern in the graph which says pH vs. Elevation. WE have noticed that the lower the elevation, the higher the pH will be. For example, Peck's Pond is 700 ft. high in elevation and the pH was 7.02. Then we looked at the highest elevation and it was 1360 ft. and that pH was 5.0. Then, if you look at all the elevations they all seem to follow this except for one which is Upper Reservoir at 1100 ft. tall. Another pattern we see is that the Conductivity will most likely go down the higher you go. Each did this except the one which says 1040 ft.
Hypothesis: Will CO2 evaporate out of the water over a certisn amount of time and change the pH?
Our experiment: We took carbonated water (seltzer), and found what the pH for that was (3.862). Then we had to wait 25 minutes to take another pH test. We wanted to test if the carbon dioxcide will evaporate and change the pH to a more nutral number. After 25 minutes, the pH of the water went to 4.056. Our hypothesis turned out to be correct. We know that it is correct because seltzer is only carbonated water. After a while ( 25 minutes ) the CO2 will go away thus making the pH nutral.
