Water sample collection and analysis and the long-term study of a local system or environmental problem are important components of an Environmental Science course. You will experience both in this experiment.


In the Preliminary Activity, you will gain experience using a Dissolved Oxygen Probe while determining the concentration of dissolved oxygen (DO) in a water sample provided by your teacher. You will also gain experience using a Temperature Probe, a Conductivity Probe, a Turbidity Sensor, and a pH Sensor. 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 long-term data collection.
