A Water Field Study

Figure from experiment 22 from Middle School Science with Vernier


When finding water quality, there are many measurements that can be made. In this experiment, you will measure water temperature, conductivity, and pH. Water temperatures in streams can range from 0°C in the winter to above 30°C in the summer. Cooler water in a stream is generally considered healthier than warmer water. Problems generally occur when changes in water temperature are noted along one stream on the same day.


In this experiment, you will

  • Use a Temperature Probe to measure water temperature.
  • Use a Conductivity Probe to measure the conductivity of water.
  • Use a pH Sensor to measure the pH of water.
  • Make visual observations at the test sites.
  • Compare water quality.
