Vernier Biology expert Colleen McDaniel and Chemistry expert Dr. Melissa Hill demonstrate how students can use Go Direct® sensors to investigate the following common water quality factors—dissolved oxygen, pH, and conductivity. Using these sensors, students can collect data from various water sources, analyze the results, and propose solutions to enhance ecosystem health.


Key Takeaways:

  • Techniques for integrating water quality testing into your curriculum ahead of teaching chemical properties of water, water pollution, watershed characteristics, and ecological parameters
  • How to prepare for going into the field, and how to do water quality testing if you don’t have access to a body of water
  • Best practices for using the Go Direct Optical Dissolved Oxygen Probe, Go Direct pH Sensor, and Go Direct Conductivity Probe to measure water quality parameters
  • Strategies for using Vernier Graphical Analysis® to help students visualize and interpret data as well as to connect abstract scientific ideas to real-world applications
