Students calculate evaporation rate using differential equations. In this calculus lesson, students explain how pan evaporation works. They complete a worksheet to sum up the lesson.

Students investigate the chemistry of coal. This lesson serves as a review of conservation of mass, simple reactions and equation balancing. During the lesson, students research chemical components of coal, as well as environmental...

Instructional module focusing on the hydrological cycle. Discussion includes the movement of water through the different reservoirs on earth and its impact on climate and weather patterns. Site also includes an interactive practice quiz...

Has general hydrology information, hydrology research updates, and data from the National Remote Sensing Center. A good site discussing current information from the world of hydrology.

Water is the source of life on earth. It exists in many forms and is constantly changing. The circulation and conservation of earth's water is called the hydrologic (or water) cycle. Find out how water evaporates, condensates,...

Has information and hydrology data from around the world. It also has a section discussing human impacts on the climate and another which covers current research.

Animation and text explain the water--or hydrologic--cycle, which is the process that water undergoes in nature.

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

This resource presents a comprehensive glossary of hydrologic terminology.

This virtual field trip for middle school students looks at aquifers and their place in the hydrologic cycle. Students learn why and how it is important to protect the source of your drinking water and some unique details about the...

The hydrological cycle is usually called a recurring consequence of different forms of movement of water and changes of its physical state on a given area of the Earth. The role of different processes in the hydrological cycle and their...

The National Weather Service offers information on the processes that make up the water (hydrologic) cycle, including evaporation and transpiration, precipitation, run-off, infiltration, and percolation. Has a good illustration and...

In this experiment, students create a model of the water cycle and learn about its crucial role in moving water around the Earth.

A very informative site, which is provided for by the U.S. Geological Survey, on how to write hydrologicic reports.

A course lecture on the external processes that shape the Earth, specifically the hydrologic system. This system is powered by the Sun's energy. The components of the Earth's energy budget are described, and how these drive the movement...

Students learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating...

Through an overview of the components of the hydrologic cycle and the important roles they play in the design of engineered systems, middle schoolers' awareness of the world's limited fresh water resources is heightened. The lesson lays...

As part of the General Chemistry Virtual Textbook, this site examines a variety of topics related to the hydrosphere and the oceans. Topics covered include where the water came from, the hydrologic cycle, Oceanic circulation, atmospheric...

Students learn about the importance of dams by watching a video that presents historical and current information on dams, as well as descriptions of global water resources and the hydrologic cycle. Students also learn about different...

This lesson teaches the concept of a watershed and why it is important in the context of engineering hydrology. Students learn about runoff and how we visualize runoff in the form of hydrographs.

Project ideas for environmental science issues, and links to homework help in geology, biology, geography, and hydrology.

Through multi-trial experiments, students are able to see and measure something that is otherwise invisible to them- seeing plants transpire. This information will allow students to consider how a plant's unique characteristics (leaf...

The U.S. Geological Survey reports on the latest news affecting the earth today, as well as providing a wealth of data, reports, and information.

Help students to understand the Geologic Cycle, Hydrologic Cycle, Physical Properties of Rocks and Surficial Processes with this learning module. Find lessons covering each topic.
