Take your students on a caving experience. This field trip gives hands-on experiences with stalactites, flow stone, fossils, water erosion, limestone, and groundwater.

Students demonstrate the relationship of groundwater to wells.

A glossary of terms that describe the processes that occur in hydrology. Glossary explains evaporation, precipitation, soil moisture, groundwater, and stream flow.

During this activity, students will learn about porosity and permeability and relate these concepts to groundwater flow. Students will use simple materials to conduct a porosity experiment and use the information to understand how...

Given scenarios, descriptions, maps and illustrations, students will be able to model the effects of human activity on groundwater and surface water in a watershed.

What are some easy ways to conserve water? This site features some practical ways to accomplish this important task. Students and teachers can work to conserve water at school and at home.

Presents a water cycle diagram with information about the different stages, a 10-question groundwater quiz, and a water poem.

This cartoon describes what the EPA's Superfund is and how water can become polluted. A lab experiment with Q&A is included.

This resource provides information on watersheds, maps, activities, and links to local watershed information.

Students work with databases and GIS to develop saturated thickness maps. Each database consists of observations made by drillers where they have encountered the High Plains aquifer base and the annual water-level measurements taken in...

This site provides a comprehensive introduction to the water cycle. Students construct a model to simulate parts of the water cycle. Includes background information, links to standards, lesson plans, and assessment ideas.

Learn about the threat of lead in drinking water and what actions you can take to prevent or deal with exposure.

Glaciers and icecaps contain approximately 70% of the world's freshwater, but groundwater is by far the most abundant and readily available source of freshwater. This graphic illustrates the quantity (in cubic kilometres) and...

See how rainwater and snow melt flows from high areas to low areas which ultimately results in Earth's groundwater.

This site briefly describes the groundwater system and the relationship of the system with the water table. A diagram is provided also.

Where does your drinking water come from? This resource features a clear and concise explanation for this question. This resource will be beneficial to students and teachers.

Find out about naturally occurring substances that also affect water quality.

Explore water pollution in surface water and groundwater and investigate the treatments for both. Also, check out what happens when salt water infiltrates the fresh water sources.

Dewdrop teaches the water cycle through this interactive map of rivers, oceans, groundwater, the atmosphere, and glaciers.

What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper?...

Chemicals from the Earth's atmosphere are making their way down to the planet. Not in spaceships, but in rain. The acid rain can infiltrate ground water, lakes, and streams. How does acid rain affect aquatic ecosystems?

Use this lesson plan to introduce students to testing water sources for pathogenic microorganisms. Students will learn methods for groundwater sampling to evaluate water quality. Lesson plan includes student worksheets.

Set in the context of ground water contamination in Bangladesh, this stoichiometry and analytical chemistry activity examines the issues around identifying wells contaminated with arsenic. In this activity, students perform a gravimetric...
