Duckweed and Fertilizer contrate Inquiry 

We had to make a procedure for our duckweed experiment. I wrote, step 1: we filled our test tubes with water (20ML), Step 2: we added 0.4ml of fertilizer, Step 3: we added four duckweed plants into the water, Step 4: we counted how many frauns there where in each test tube, Step 5: we wrote how many frauns there were in the test tube,
Where Phosphorus In The Lake Comes 
From 12/15/16 Info from 11/7/16

The Environmental Protection agency Estimated that 17.1% of phosphorus in the otter creek watershed came from the forest from forestry. Otter Creek watershed is 60% forested.

The forest is the second biggest source of Phosphorus in the otter creek watershed following Agriculture,at 49%, in third is stream erosion, at 16.4%, fourth is Developed land with 14.4%, The last contributor is wastewater treatment facilities with 14.4%.

Department of forests, Parks and Recreation forestry district manager, Gary Sabourin says “That there hasn’t been a lot of research done on phosphorus contributions from forest land, he has to think that it is relatively low per area. But because forest lands cover such a huge amount of the basin of lake champlain. That it represents a big portion of phosphorus in Lake Champlain.

#O2 level test 11/21/16- 11/22/16

In science we did a dissolved oxygen test to find if Cedar lake is healthy and to see if our guppy tank is healthy for different animal life than what is in it right now and to see if the guppy tank and Cedar lake are healty. We had sample (a) as the pond water and sample (b) as the guppy tank.

My claim is that I don’t think Cedar lake is healthy because their is a lot of invasives that take up a lot of the water surface.

In sample A this is what happened: We first put manganous sulfate & iodide-azide (created the flocculate or floc) which made an orange rusty color. The floc looked like orange pulpe. Next we waited for the floc to settle half way so we could do the next part, the next part we put ulfamic acid (dissolves the rest of the floc) the ulfamic acid made most of the floc go away and turned the water a Root beer brown color. The last test we used sodium thisulfate (drops that we added until the water was clear) for sample (a) it took 14 drops of sodium thisulfate to turn the water clear again.

Next we did the same test with sample (b). When we added manganous sulfate & iodide-azide (created the flocculate or floc) which made a rusty color that made the bottom of the sample chuky. Next we put sulfamic acid (dissolves the rest of the floc) their was still a little floc. The floc particles were a rootbeer brown color and floatingat the top. It took 10 drops of sodium thisulfat to make the water clear agian.

From each step, from each sample it showed that their was not an animal diversity sustainable life with the O2 level test with both of the samples. Sample a had a mgl level of 3 and 2. In Texas cedar lake would be healthy but cedar lake is in vermont and in vermont the mgl level needs to be 7.

I made my claim saying that Cedar lake is not healthy because the invasives take up the most surface space in Cedar lake taking the O2 away from the fish and killing them.


Some of the point source pollution I saw was me and my neighbors chicken coop.The chicken coop is at the top of a hill and at the bottom was a stream that goes to a marsh. The chicken poop was watery. Another point source pollution is the vermont gas pipeline with all of the trucks and machines and pipes in the ground. the last point source pollution I saw was a pipe going into a stream with water coming out of it. One of the non point pollution I saw was gas that spilled out of a car that was flowing down a drain pipe. Another one is that their was cigarettes next to a drain pipe. Their was a broken beer bottle wright next to the river.


Land Uses in the country
The Agricultural Land use. A Vegetable farmer sprays fertilizer on his crop, and pesticides. If the rain comes down in twenty four hours than the pesticides affect the rains water quality. The fertilizer will affect the water quality because the fertilizer will go into the ground affect the groundwater and the runoff, because the fertilizer is most of the time is poisonous if you eat it or if you get it in your eye. And then you put poisonous fertilizer on the ground and know that the rain has come down it is know in our water system in your area.
