Fertilizer in Duckweed Experiment

This week(and last week) for science we read four pages in our book. We had to write a prediction of what happens if you put fertilizer in duckweed(or Lemnoideae if you want to use the scientific name for duckweed). I wrote, I think fertilizer will make the duckweed grow slower if put 2 pounds in. still if you don’t put much in I think it will still make it grow slower. Why I think it will make it grow slower is because on page 57 (of our science binder) it said duckweed is a plant that grows in water rather than soil. What I can assume from that is that duckweed doesn’t grow as well in the ground as it does in water. 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, on the test tube, Step 6: we wrote down our procedure.

Phosphorus in Vermont

Something we learned this week was things about phosphorus. By ourselves we read a article it was called ¨Where phosphorus in lake comes from¨. It is about amounts of phosphorus. Did you know that 17.1% of phosphorus in Vermont is in Otter creek. 49%Of phosphorus is in agriculture. 17.1% of phosphorus is in Forest/lands.16.4% of phosphorus is in Stream erosion. 14.4% of phosphorus is in Developed lands. 3.2% of phosphorus is in wastewater treatment facilities. Another thing about phosphorus according to EPA’s estimat that forest lands are the second largest contributor of phosphorus within the Otter Creek watershed next to agriculture.I highly doubt you knew that, I know I didn’t.

This week in science we have been working on seeing if Monkton pond is in the healthy. We also have been working on seeing if Ms Gagner’s water in one of her fish tanks is healthy. We used chemistry to find out if the water was healthy. We had to add a few chemicals such as manganous sulfate, iodide-azide and sodium thiosulfate. When we put iodide-azide in the water it started to look a little foggy. When we put manganous sulfate in the water it turned to a mango like colour (it reminds me of a very bubbly orange drink sort of like a bubbly orange soda). When we put sodium thiosulfate in the water the bottom started to clump(it looked like orange clouds on the bottom)it changed to a apple juice sort of colour. When you put sulfamic acid in the water it starts to become a little lighter when you shake the bottle with the sulfamic acid it took 14 drops for the pond water. The fish tank water took 10 drops. It ended up that in monkton pond there is only 2 milliliters of water per gram in vermont the average should be 7 mlg so that is not good. In miss Gagner's fish tank there is only 3 milliliters of water per gram.That is what I have learned in science This week.

When I was on vacation I saw 5 sources of point pollution and non point pollution.For point pollution I saw somebody leave trash on the side of the road, iv'e seen people use firewood, on the news iv'e seen seen things about oil spills, I saw somebody using a leaf blower and in places like lake Eire people pollute water [I saw a river that was polluted]. Why leaving trash on the side of the road is bad for the environment is because if it rains the water can bring it to a river. Why using firewood is bad for the environment is because the smoke from the fire would pollute the air .why oil spills are bad for the environment is because the oil washes up on land and pollutes the water and kills any animal in the water that is close to the oil. why using a leaf blower is bad for the environment is because it pollutes the air. why polluting water is bad for the environment is because it will pollute every bit of land around it.For non point pollution I saw a truck that was left on, I saw garbage on the side of the street. I saw a huge tractor left on, I saw someones lawn that had fertilizer on the ground and I saw multiple people put oil in there car. Why leaving your truck on is bad for the environment is because the smoke coming from the truck will be bad for the air. Why leaving garbage on the side of the road is bad for the environment is because when it rains the garbage will wash away into a river or something [if there is a river or pond nearby]. Why leaving a tractor on is bad for the environment is because the smoke from the engines will go in the air and that's bad for the air. why putting fertilizer on the ground is bad is because when it rains the fertilizer will mix into the ground it will be bad. Why using gas is bad is because sometimes when people are traveling oil across the water oil may spill.I also saw 7 places water and land where interacting. Here is what I saw. I saw a sprinkler on, it was raining, I saw a river, I saw a pond, I saw a ocean, I saw a lake.

What I did For Science This week

This week we have been looking at 2 pictures one was a agricultural place the other one was a commercial place. What we were looking for in the pictures was what what happens to the environment when you do things like wash your car or use a leaf blower. Why washing your car is bad for the environment is because if you are using soap and some of the soap goes on the ground you are polluting the environment. Why using a leaf blower is bad for the environment is because you are polluting the air. Some other things we talked about was how doing construction , pouring something into a sewer and taking care of your lawn is bad for the environment. Why doing construction is bad for the environment is because the machines use gas. Some of the times people bring oil over oceans by boat sometimes the oil spills and that’s bad for the environment. Why taking care of your lawn is sometimes bad is because you can put fertilizer on your sprinklers and that is bad. Why dumping something into a sewer is bad for the environment. Is because if there are mosquitoes with Malaria and a animal drinks it the animal can get sick and that's bad. That is what I learned in science this week.
