Curated OER
Water Quality
Students investigate the water cycle and evaporation. They study the porosity and permeability of groundwater, and the capillary action in soil in this unit.

Journey Through the Water Cycle
Students canvass the water cycle in the seven lessons of this unit. The processes of the water cycle and the cyclical nature of water is emphasized inthis unit.
Curated OER
"Tri-County" Project--Ground Water
Students explore data on some of the landforms in Nebraska to distinguish between porous and nonpremeable soils. The state's groundwater is investigated.
Curated OER
"Tri-County" Project--Water Cycle
Students analyze the parts of the water cycle through research and experimentation. Particular attention is paid to the processes of evaporation and condensation.

"Arsenic and Old Waste": Groundwater Activities Using Modeling
Learners develop models of groundwater and pollution flow. They research information using the Internet and develop models of groundwater flow in Stella and Excel.
Curated OER
"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.

There Must Be Something in the Water
Students read a New York Times article as a class and discuss how groundwater near a nuclear test site may have been contaminated. They explore how groundwater contamination can spread through aquifers by participating in a simulation.

Aquifers: Unlimited or Not
Young scholars understand that an aquifer can become a non-renewable resource if it is not used wisely. Students do an experiment that recreates an aquifer in the classroom.
