Getting the Word Out
An appropriate way to celebrate and conclude the construction of a rain garden is to share it with the community. Small groups collaborate to design an outreach product such as a PowerPoint presentation, brochure, or poster, to draw...

What Is a One Part Per Million Solution?
Water may appear to be crystal clear, but there could be dissolved substances present. Lab groups make a one-part-per-million of a food coloring solution to demonstrate this concept. As part of an outstanding unit about water, this...

The Water Cycle
Young scientists get their feet wet as they learn about the water cycle in this series of activities. Whether they are observing how evaporation causes puddles to dry up, or how plants put water into the atmosphere through transpiration,...

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...

Types of Water Pollution
In groups, young environmentalists investigate water samples that are contaminated with different types of pollutants. Each group presents their findings to the class and fills out the "Types of Pollutants Chart." This lesson is meant...

To Filter or Not to Filter
Drinking clean water can be taken for granted. Explore the process and high cost of filtering water with a water pollution and filtration activity. Young scientist build a filtration system to filter polluted water, examine the economics...
