Students are exposed to the extensive ways humans use water beyond daily personal use. Students sort cards with these diverse uses and categorize them.

The water cycle model demonstrates evaporation, condensation, precipitation, and run off. A light bulb and ice bag are used to facilitate heat exchanges inside a plastic container to make evaporation and condensation. Then condensation droplets fall and run off into the container.

The groundwater models demonstrate the relationships between the zone of aeration, zone of saturation, and the water table as well as porosity and permeability variables.

Students are introduced to and provided information about types water pollution sources. They then categorize examples of water pollution according to their types.

This document is a condensed version of the EnviroScape model manual. This quick reference provides a table of discussions, demonstrations, and supplies needed to show how water is polluted and how to prevent water pollution. 

A glossary of terms describing karst features and related groundwater terminology.

The students participate as if they are matter traveling through the rock cycle. They draw cards that direct them to one of four stations to demonstrate the process. Rocks are provided for examination at stations.

Students get a glimpse of the long slow process of how sediments settled long ago before becoming sedimentary rocks. Students put various sediments in jars of water and discover how settling rates can vary.

This activity demonstrates how calcite, Missouri’s most common mineral in limestone, gets dissolved by slightly acidic rainwater. This is how karst features were created.

This lesson will provide a home inventory (checklist) for student to conduct at home with their families. The inventory is designed to examine their own “deep feet water footprint” on groundwater in the karst terrain of the Missouri Ozarks. Emphasis is placed on methods to decrease nonpoint pollution coming from their homes, yards, sewage systems and other land use activities. …

After watching the online video “Karst in the Ozarks,” students sort cards depicting actions by fictitious people. This way students demonstrate their understanding of karst topography.

Students design and construct a cave diorama from a box. They demonstrate how human activities on the surface can affect cave water quality below. They are able to learn about speleothems and get creative in the process.

Using sugar cubes, clay, and warm water, students create a model that demonstrates how solution caves form. They see an accelerated simulation of a slow processes that happened long ago and is still slowly occurring.

Trees play an important part in a watershed to protect water both above and below the ground. Common objects are used to demonstrate the FUN functions of trees and their importance to the quality of our hydrosphere, atmosphere, and biosphere.

This background sheet provides real world uses of this tool as well as the untapped education application in physical, Earth, and environmental science classrooms. Safety guidelines for classroom use are included.

This document categorizes point sources of water pollution. Background information is included.

This document categorizes nonpoint sources of water pollution which in most cases in not regulated. Background information is included.

This document categorizes methods that land owners and others can use to prevent and reduce nonpoint water source pollution from various land uses. Links are included for more information.
