This lesson, provided by Science NetLinks, teaches students the importance of healthy ecosystems by investigating the example of natural water purification. Students will learn how ecosystems remove pollution from the water and how much it costs humans to do this artificially once ecosystems are no longer healthy. The class will then create a "River Newspaper" reporting on the condition of the local environment.

The Gold Rush, positive for California in so many ways, had a ...

The Gold Rush, positive for California in so many ways, had a devastating effect on the state's environment. Many of these problems were directly related to gold-mining technology. The process of hydraulic mining, which became popular in the 1850s, caused irreparable environmental destruction. Two images show California's largest hydraulic mine ? Malakoff Diggings, in Nevada County ? in action. (Malakoff Diggings is now a state park and open to visitors.) Dams (such as the English Dam in Nevada County, shown in one photograph), which were constructed to help supply water to the mines during the dry summer months, changed the course of rivers. The sediment washed away by hydraulic mining clogged riverbeds and lakes, threatening agriculture throughout the Central Valley. Conflicts over water arose between mining and farming interests. Hydraulic mining essentially came to an end in 1884 with the Sawyer Decision, legislation passed to resolve this conflict. The mining industry also needed a great deal of wood, both to fuel the boilers at the mines and to build extensive canal systems. This demand for lumber helped create the logging industry. California's forests had plenty of trees to log, many quite large. The lithograph "The Stump and Trunk of the Mammoth Tree of Calaveras" depicts a society ball at which 32 people danced on the stump of a giant sequoia tree. Photographer Carleton E. Watkins was well known for his images of the grand views of the West. He was the first to capture Yosemite on film, and helped shape how people throughout the country and the world viewed California. He took many of the broad landscape photos in this group. Watkins also made use of the new technology of the day to create stereoscopic views, including the image of the Malakoff Diggings. There are also several Daguerreotypes in this topic. They include a portrait of John A. Sutter (at whose mill gold was first discovered); miners at work; miners with equipment; and general scenes of mining operations.

This is a 21 day unit on the topic of floods. Students will plan and prepare for what might happen in the event of a flood in our area. We have had floods in the past that have affected the Walterville School, its campus, and the surrounding areas. Using this as a springboard, students will discuss the effects of flooding, do research and interview family members who have experienced flooding, and then discuss possible ways to prevent significant damage on the buildings and surrounding areas. They will then design a barrier that could protect an area from damage for a period of time. Students will need materials to conduct experiments. We have listed these in the lesson plan. We have also included a trip to the Leaburg Dam so that students can learn about dams and their uses. We plan on teaching this unit in the fall.

For the first time in history, the global demand for freshwater is overtaking its supply in many parts of the world. The U.N. predicts that by 2025, more than half of the countries in the world will be experiencing water stress or outright shortages. Lack of water can cause disease, food shortages, starvation, migrations, political conflict, and even lead to war. Models of cooperation, both historic and contemporary, show the way forward. The first half of the course details the multiple facets of the water crisis. Topics include water systems, water transfers, dams, pollution, climate change, scarcity, water conflict/cooperation, food security, and agriculture. The second half of the course describes innovative solutions: Adaptive technologies and adaptation through policy, planning, management, economic tools, and finally, human behaviors required to preserve this precious and imperiled resource. Several field trips to water/wastewater/biosolids reuse and water-energy sites will help us to better comprehend both local and international challenges and solutions.

This lesson provides an overview of the primary influences of watershed and channel sedimentation. In a short narrated portion of the lesson, we explore a section of the Rio Grande watershed and channel in New Mexico using Google Earth imagery, river profiles, and graphic animations. We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary processes in sedimentation: generation, transport, and deposition. The lesson then addresses natural climate and weather influences along with some observed and projected trends associated with climate change.
