Description
The purpose of this experiment is to test the effect of a phosphate on the oxygen levels in pond water. I believe that the phosphate will have an effect on the level of oxygen in the pond water. I think that the pond water with only ten drops of the phosphate mixture will have have more oxygen than the pond water with fifty drops of the phosphate mixture.
