The hypothesis is that the more turbidity levels in water increase, the more dissolved oxygen levels decrease.

You will find an area of water to test, put a jar beneath the river surface, add dissolved oxygen pillows to the sample, and measure the turbidity levels with a turbidometer.

You will need a turbidometer, bottle with stopper, dissolved oxygen pillows, sodium thiosulfate, protective gloves, nail clippers, boots/hipwaiters, testing tube, and 10 quart jars.

The results of the experiment indicate that higher turbidity levels actually increase the level of dissolved oxygen in water, which is contrary to the hypothesis. This experiment could lead to further exploration of how turbidity affects photosynthesis.

This science project is interesting because it explores the relationship between two important factors in water quality, turbidity and dissolved oxygen.

Experiment variations to consider include testing different types of water, such as salt water or fresh water, or testing different levels of turbidity.
