With almost half of Americans relying on groundwater supplies, it is more important than ever to protect aquifers from possible contaminants. Working in small groups, young environmentalists explore this problem as they create an aquifer...

Learners analyze how engineers study temperature inversions and convection currents to understand why pollution levels may be higher in some areas than others. They participate in an experiment that allows them to build simple models to...

Learners evaluate the effects of point and non-pointy sources of water pollution using a model. They assess human impact on water quality. Students build a model which represents an aspect of the hydrosphere and compare their model with...

Students are introduced to the concepts of a watershed, stream flow and water quality. This five-day plan is an excellent way to introduce students to the concepts involved. They create their own watershed using a paper bag, water and...
