Environmental Science
It all started on April 25th 2022 in the OGS (Ocean Guardian School) we started with what team we wanted to be in. Me and my teammate wanted to be in pH since it sounded fun. But when we got a sheet to understand our assignment we didn't understand a bit of it just looking at the sheet blindly. But when we fully examined it we understood what the equipment was for and what to do. We got introduced to pH, Stream Temperature, Dissolved Oxygen, Turbidity, Conductivity and Flow rate on the same day. From the information we gathered, and we have came to understand that our Creek is doing well. For further information we have a pH scales between 5-7 but more detailed information for each day and 8 averages we have: 4/28/22 we got 6.075, 5/2/22 we got 6.34, 5/3/22 we got 6.44, 5/4/22 we got 6.41, 5/5/22 we got 6.08, 5/6/22 we got 6.315, 5/11/22 we got 6.035, 5/16/22 and finally we got 5.985 but all the averages combined from 2021 and 2022 we get an average of 6.21 for which is a good quality for fish to survive and breath. But if the water is below or above a 6.21or 7 then the fish cannot breath and would move on to a different Creek. But most of the time we got a 6, and I think this happened because most of the time we go down to the Creek we see garbage and open beverages that spilled into the creek to make it more acidic, and my data supports my claim because anything below a 7 is more acidic and has more free hydroxyl ions, and if the water was more basic it would have more free hydrogen ions therefor the water in our Creek has more free hydroxyl ions.
From what you see in this photo here there is a pH sensor we use it to collect data. For example we took the bottle you see in the image off. It's filled with a solution to get rid of the bacteria from the last time it was used. The plug in you see on the end or the pH sensor we plug into the LabQuest2 as you can see in the photo below.
Here is the LabQuest2 after we plug in our pH sensor and get data from it, it send the data to the LabQuest2 for us to review and compare to the ph. scale to see if the Creek is doing good, well, ok, bad, or worse then the last couple years of data.
As you can see here. There is a pH scale with 14 numbers, And I will be explaining what each number means I will start with 7, seven has equal free Hydroxyl ions and equal free Hydrogen ions. It was given a nickname natural and pure water, and anything below a seven is more acidic and has more free Hydroxyl ions. But if it were higher than a seven it would be more basic\alkaline.
