Congratulations on your first water testing experience!

Hello! If you have found this page, that means you’ve completed your first water testing experiments with your class or camp. We want to thank you for taking part! Water testing is important for our water health and for our understanding of science, and we can’t do it without you.

You are now a citizen scientist!


  1. Used your senses to test a hypothesis
  2. Conducted water chemistry tests
  3. Learned every water body is unique!
Learning together is more fun!

You’re part of a bigger movement!

Congratulations on taking the first steps towards becoming a Water Ranger. If you’ve made it this far, you’re well on your way to mastering the basics of water testing! We believe that the best way to learn water testing is by getting your hands on the equipment. We are confident that over time and with practice, you’ll become an expert!

If you are anything like us (and we have a feeling you might be), you’ll probably become curious about what else you can do for water now that you’ve taken these first few steps. For more ideas on how to get involved, follow us on social media! Our growing community of water enthusiasts is sure to inspire you, and we hope you’ll continue to be a part of it.
