So I'd like to explain a dissolved oxygen demonstration to you that we did in class. You see, dissolved oxygen is a relative measure of the amount of oxygen that is dissolved or carried in a given medium. In our example, we had four 2-liters that were all filled with water, but had other things as well:
-Control bottle: tap water and gravel
-Bottle #1: tap water, gravel, a plant
-Bottle #2: tap water, gravel, a plant, lake water
-Bottle #3: tape water, gravel, a plant, lake water, a fish
We checked the temperature, Conductivity, pH, and Dissolved Oxygen percentage of each bottle, and the results are in the picture below.
