Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

How much is too much nitrate in the water? Young scientists discuss the question after they run their own nitrate tests. They also consider sources of nitrates and offer explanations for the levels.

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Want to know a secret? Young chemists may dismiss the idea of needing to test for the presence of water after a chemical reaction,  but when you tell them they can create invisible ink in the process, that might get their attention!...

This field investigation will be in collaboration with Eagle Bluff Environmental Learning Center in Lanesboro, MN link to Eagle Bluff. It will include chemical, biological, and physical tests. The chemical tests will include kits where...
