My Trip To Canarsie Peers

      The first thing I saw when I entered Canarsie Peers was a very big, foggy river.  There was trash in the water and strange enough the water was absolutely still.  The first test we did was when two of the instructors went into the water with a net and pulled in small organisms.  They caught crabs, snails, seaweed, moon jellies, and a variety of fish.  The moon jellies were very squishy and completely transparent.  We caught a fish that only swam on his side and with both eyes on one side. This fish was brown on the side with the eyes but silver on the other side. This fish was smooth.  We caught hermit crabs. snails and huge crabs.  I cataloged them inside of my science notebook and drew sketches of them on a special paper. The hermit crabs very small and the shells were black. I noticed that once you picked them up they will start to come out of their shells. The bigger crabs were slightly bigger than my palm and were very aggressive. The were black in color. We also caught a fish that looked like a sardine but it wasn't. I think it looked like a darter except it didn't have a dorsal fin.

      Next we checked the tempature of the water and the air.  The tempature of the air was 78 degrees and the tempature of the water was 65 degrees farenheit.

      The next test we did was the sediment test. My teacher, Mrs. Singhal took a long pole and stuck it into the water and sand at the bottom. When the pole comes out it will have collected sand and a small amount of water. The sand took up 18 cm of the pole. We had to use a little bit of water to get the sand out of the pole but miraculously the sand held its shape. When we looked inside the sand we saw what looked like shell grains and pebbles. There were also things that we could not identify.

     Next we did a clorofil sample. The steps we performed were

  • Unscrew filter holder
  • Grab filter with a pair of tweezers
  • Close filter holder
  • Collect 60 milliliter of water
  • Screw on filter
  • Push out water
  • Remove filter
  • Open up filter
  • Remove filter paper with tweezers
  • See what color the filter paper is Compare the color of the filter with the sheet

We thought the filter paper looked like a 5 because it was looked tanish

          The final experiment we conducted was the wind speed. We estimated that the wind speed was around 1.

         I liked this trip to Canarsie Peers because it was fun and educational.
