Water sample collection and analysis and the long-term study of a local system or environmental problem can be interesting components of a chemistry course. You will experience both in this experiment.


In the Preliminary Activity, you will gain experience using a Temperature Probe, a Conductivity Probe, and a pH Sensor as you measure the temperature, conductivity, and pH of a water sample provided by your instructor. If a Turbidity Sensor and a Dissolved Oxygen Probe are available, you will also measure the turbidity of and the concentration of dissolved oxygen (DO) in the water sample. You may or may not choose to use all five of the sensors as you subsequently research your chosen question.

After completing the Preliminary Activity, you will first use reference sources to find out more about water issues before you choose and investigate a researchable question that involves longterm data collection.
