test that we did to find the health of the River.

• Our class did many different test to find the
  health of the River.
• First thing that we did was find the temperature.
• The first test that we did was dissolved oxygen.
• The second test we did was PH.
• The third test we did was nitrate.
• The forth test was phosphate.
• We were set up in gropes to find the results for
  the tests.

TEmperature.

• The reason that our temperature and other test
  have different results is we were in 3 gropes and
  we were in 3 different parts of the river.
• The way we found the temperature was we had water
  thermometer in the river for about a minutes and
  take it out and read it.
• The results for the temperature is 18ºc, 16ºc,
  18ºc, and 16ºc. For a mean of 17ºc.
• Even though we were in 3 groups some did more
  than 1 temperature.
• This is one of the thermometer that we used to
  find the temperature of the river
• After we put it in the river it would glow the
  number that the river temperature is.

First test Dissolved oxygen

• Dissolved oxygen (DO) is important to the health
  of aquatic ecosystems.(from low cost water
  monitoring.)
• Our test results for gropes that did DO are4 ppm
  4 ppm and 8 ppm resulting in 61 (not bad, but
  not great either).
• The way we found the DO for the river was by
  dropping 2 tablets into a tube of water from the
  rive.
• This is similar to what we looked at to mach up
  the colors.
• Ours was more in the middle of the 2, and 5.

Second test pH

• This is similar to the one we looked at when we
  did our test pH.
• pH is a measure of acidic or basic quality of
  water. (From Low cost water monitoring.)
• The way we found pH was by adding one tablet to a
  test tube of river water, we let it sit for a
  minute and matched it to a color on the
  chart.(like shown in the picture below.)
• Our test results for for pH are 6.5, 7.5, 8.0
  ,6.5, 7.5, 7.5 we have more than three is because
  some gropes did more than one test. For a mean
  of 7

Third testNitrate

• Nitrate is a nutrient needed by all plants and
  animals to build protein.(From low cost water
  monitoring.)
• Our test results for nitrate are 0ppm. There are
  only one because we only had one grope do
  nitrate.
• The way we found nitrate was by adding 1 nitrate
  tablet to the test tube of river water and
  rotated it back and forth for a minute.
• This is similar to the one we looked at for the
  river.
• Ours was the wight, is 0 ppm.

forth testPhosphate

• Phosphate is a nutrient needed for plant and
  animal growth and is also a fundamental element
  in metabolic reactions.(From low cost water
  monitoring.)
• Our test results for phosphate are 1 ppm. We
  only have one because we had one grope do the
  test.
• The way we found nitrate was by adding one
  phosphate tablet to a test tube of river water.
• This is similar to the one we used to find ours.
• ours was the first light blue one.
• Less than 10 ppm

conclusion

• After all the test that we did on the color
  charts there were light color and dark color ours
  were the lighter colors. After I looked at the
  results twice I found out that our river seems to
  be pretty healthy and safe for most of the
  animals to live in. I am glad that our river is
  fairly healthy for the environment and the
  animals that have a home in the Black River in
  Cavendish.
