Students use the Internet to research current and past snowpack levels and river gauging station readings. They determine the relationship between snowpack and river flow. They predict future river flow.

Students examine limestone cave geology and hydology. They study cave vocabulary.

Ninth graders analyze a fantasy art map by Jeremy Anderson, paying careful attention to the way the topographic features of the land are represented. They create a similar map of Sacramento that includes topographical features as well as...

Young scholars discuss how groundwater becomes polluted. In groups, they design and create models of groundwater pollution sources. They demonstrate to the class how the water may become contaminated from local and nonlocal pollution...

Students explore energy and nutrient flow. In this science instructional activity, students diagram the flow of energy through food chains and food webs. Students discuss the importance of energy flow in Earth's ecosystems.

Step-by-step, arrow-by-arrow, viewers are walked through the rock cycle. In the end, you have a simple, yet complete diagram of the process. Pictures appear to show samples of igneous, sedimentary, and metamorphic rocks. The presentation...

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

Students role-play expert witnesses in a mock trial dealing with contamination of groundwater. They prepare for the role-play by studying the movement of groundwater and the transport of contaminants through computations, map exercises...

Students investigate the various factors that influence the Pacific Ocean and Monterey Bay, California. They watch a video about Monterey Bay and take notes, and conduct research and write a report about a specific organism living in...

Students, through a series of lessons, study the various processes of treating wastewater. They participate in discussion and complete various worksheets and a hands-on activity, in which they observe the processes of filtration and...

Students are introduced to Delaware's waterways as precious resources used for drinking water, water for agricultural and industrial uses, recreational areas, and as habitats for wildlife. They are introduced to wastewater discharges,...

In this science learning exercise, students learn about water cycle, weather, clouds, storms and water resources by completing 8 pages of this full color newsletter. Students read a story, study weather maps, learn to make a rain gauge,...

In this water web worksheet, students explore, analyze and discuss how weather stations interact with maintaining weather conditions and answer two essay questions and ten multiple choice questions.

Students build a model to simulate parts of the water cycle. They recognize and explain the essential elements of the water cycle.

Students study bogs. They tour, collect physical, chemical, and biological data and analyze a pristine bog community. Using the data, they draw a map and a cross section of the bog.

Students are introduced to the water cycle and water movement in soil. In this water cycle lesson, students explore how water moves through the water cycle and discuss water sources, natural reservoirs, soil...

Ninth graders build an "Earthquake Machine" (a manipulative model of a fault line) and use it to explore stick-slip behavior of some faults and to develop a more accurate definition of an earthquake and its causes.

Ninth graders create a model of a city street with various sizes of buildings on it. They use the model to demonstrate the effect of building oscillation during varying degrees of seismic activity.

Students perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.

Students describe the water cycle and create a Mobius strip model. They determine that the weathering of rocks continually adds sodium to the Earth's rivers and subsequently to the oceans. They discuss the fact that the water on Earth...

In this fresh water worksheet, students click on the links in the questions about fresh water to find the answers and then come back and answer the questions. Students answer 9 questions total.

In this learning about watersheds learning exercise, students answer 15 questions using links to web resources about water use in their community.  This page includes numerous links to helpful websites.

Students collect specimen and analyze it. In this biology instructional activity, students analyze and evaluate the diversity found in specific environment. They use the correct terminology as they do their write up for the experiment.

Students become familiar with the water cycle and water issues.  In this water lesson students examine what they can do to protect their water.
