We learned a lot on the artist boat field trip it was a fun an amazing experience. I have been on artist boat before and it was fun I learned something new every time I went. We learned about stuff like pH, Turbidity, and Salinity all very important things to test in an ecosystem. pH is the acidity in the water. This can be harmful to the ecosystem if there is too much or too little of acidity in the water if the acidity level is to low or to high then the organisms in that ecosystem could die.we test the acidity with litmus paper it is a small strip of paper you dip it in the water and the strip turns a certain color there is a key and the color that matches the color on the key gives you a number and that is the level of acidity in the water. Turbidity is the murkiness of the water this can be harmful to the ecosystem because if there is to much dirt and pollution in the water then the oxygen cannot pass through and the fish cannot breathe. Salinity is another very important water quality test that needs to be checked often. There is a instrument called a refractometer you place a small drop of the water you are testing in the refractometer close the refractometer and it shows a number and that is how much salinity there is it should be about 20 psi.I would like to become a marine biologist when i get older.people need these test and they use them in their every day lives pool cleaners use them, marine biologist use them and lots of other people use them.

I had a great time on artist boat and i am hoping to go back some time
