Swamp Trip

Today at the Cypress Swamp, I learned that the pH of the water was like 7.5. I learned that the salinity was 1 parts per thousand. I saw 3 alligators and 1 was big and got close to my kayak. I learned that scientist use pH and salinity testing to measure how healthy the water is. I also got to use the tool that measures the salinity in the water and it was called a refractometer.
