Water Temperature, Turbidity, and Fecal Coliform
May 31, 2017
I observed that Tempecher is very important to all of the animals and plants that live in the pond because if the water is too cold for the plants and animals it could kill them. If the water is too hot and the animals and fish are cold blooded it could kill them.
If there are more plants then then there will not be more oxygen because the plants absorb a lot of oxygen. So if there were less plants under water then we would not have to worry about animals and plants die.
If the tempchar changes before the animals that need to move can move then then balance will become unbalanced then the ecosystem will become unbalanced. If the ecosystem becomes unbalanced then the hole ocean will become unbalanced.
Thermal pollution is change of tempchar. If the water gets too cold or to hot it could damage the balance that keeps the animals alive.
Scientists measure the water quality by testing the water from the lake,river,pond.
The reason it is important to measure the turbidity of the water is because if you don't then it could kill the fish/animals and plants because too much baterya.
Turbidity is murky water that has been made from the bottom of boats and the stuff that people throw in and drag in when they go fishing.
The reason fecal coliform needs to be measured is because if there is too much then it could kill everything that goes in and everything that lives in there. It could cure fish and other things that live in that body of water.
How fecal coliform bacteria ends up in the river is it runs down with the water and remains of pavement. It flows into the river and flows with the current and kill all of the living things that live in the river.
You can't really change the temperature, turbidity and amount of coliform in the water without changing the balents.
When we did the science blog two weeks ago I was a little anxious every time we poured the tea because one time it went down fast, one time it went down very slow, and one time it went down kind of fast, so I was anxious to see what the next speed is going to be every time.
For the next time that I make a filter I would use a soda bottle, coffee filter, and sand and gravel.
I think that time is more important than money because if the water clogs up than the water will build up and go around the filter and pollute the filtered water.
I predicted that the sand and gravel (mostly the gravel) would not work because it would clog the tea and prevent the tea from going through the hole at the bottom of the cap, I also predicted that the screen would not do anything, I also thought that coffee filter would some what work.
Inquiry set up. When we where starting the Duck weed proses we added 20ml of water. Then we added a small pinch of fronds. After that we wrote the numbers of fronds on the bottle so we know how many fronds we have in each of the bottles. After we aded the fronds we then added one ml of liquid fertilizer. Then we put the test tubes on the rack so they cold get some sun but before we put them on the rack we put the number order that the bottles where in on a peas of pepper so we know which group the rack goes to.
Phosphors set up. Phosphorus is a cemicle that is bad for the water. With all the farms around the water is not heathy. The stuff that the farmers use is called fertilizer. Fertilizer is killing fish and some plans. Each farm can hold 1,00 chemicals. If the river has too many chemicals in it the chemicals will kill all the plants and animals in the lake or river. Fertilizer concentration can affect the growth of duck weed. To much bacteria can kill plants and animals because there is not enough oxygen.

My class and Mrs.Pierpont’s classes came together and tested 3 different samples of water. One was from our guppy tank and the other was from Monkton pond a week ago. The third one was from Monkton pond yesterday. We took some notes from 3 different categories: Raw Data, Evidence, and Reason. For raw data I compared sample A and sample B. Sample A is sort of foggy. When we added sulfate to sample A, both A and B looked like rust. Both A and B is starting to chunk up. We added oxygen to sample A. For evidence there were chemicals in sample A and sample B. My claim is that all 3 samples are going to show different results. My reasoning for my claim is because the guppy water is cleaner than the pond water and even though there are 2 Monkton pond samples one is more different than the other because one has been out of Monkton pond longer than the other.

In science my class and l have been studying the water uses of Monkton pond and trying to see what is making the water so polluted. We made our own models.Before we made are models we made a predictions and filled out some questions.then we made a good model and a bad model. After we made the good and bad model we ran them. When we ran the examples we had to watch what happened to the water. We put blue food coloring in the water so we can see if the water changed color or if it got dirtier. I noticed that for the bad model the water got stuck in between the rocks and trash and it picked up the trash and dirt. For the good model it picked up only the dirt because it was not polluted like the bad model was. And after we ran our models we answered more questions. I hope you enjoy!
