What's So Special about Bottled Drinking 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...

Water Remediation Lab
Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

The Hydrologic (Water) Cycle
Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

Pollution in the Air and the Water Pollution Solution
Students explore air pollution. For this ecology and air pollution lesson, students perform an experiment in which a Vaseline coated lid is placed inside and outside the classroom. Students make predictions and then record what they see...
