ASMET: Satellite Precipitation Products for Hydrological Management in Southern Africa
Conditions of Use:
Read the Fine Print
Rating

This module introduces a variety of meteorological and hydrological products that can improve the quality of heavy rainfall forecasts and assist with hydrological management during extensive precipitation events in Southern Africa. Among the products are the satellite-based ASCAT, SMOS, and ASAR GM soil moisture products and the hydro-estimator. The products are presented within the context of a case, the flooding of South Africa's Vaal Dam region in 2009/2010.

The Ancient Ingenuity of Water Harvesting
Rating

With wisdom and wit, Anupam Mishra talks about the amazing feats of engineering built centuries ago by the people of India's Golden Desert to harvest water. These structures are still used today -- and are often superior to modern water megaprojects. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 17-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

Are Dams Forever?
Conditions of Use:
Read the Fine Print
Rating

Students learn that dams do not last forever. Similar to other human-made structures, such as roads and bridges, dams require regular maintenance and have a finite lifespan. Many dams built during the 1930-70s, an era of intensive dam construction, have an expected life of 50-100 years. Due to inadequate maintenance and/or for environmental reasons, some of these dams will fail or be removed in the next 50 years. The engineers with Splash Engineering have an ethical obligation to remind Thirsty County of the maintenance and lifespan concerns associated with its dam.

Burd Run Interdisciplinary Watershed Research Laboratory
Conditions of Use:
Remix and Share
Rating

The Burd Run Interdisciplinary Watershed Research Laboratory at Shippensburg University of Pennsylvania (SU) is a cooperative effort among 13 faculty from the Departments of Geography-Earth Science, Biology, and Teacher Education. The goal of the laboratory is to provide intensive undergraduate field training through collection and analysis of related hydrologic, geologic, biologic, and geographic data from a single watershed, establish a comprehensive statistical and spatial watershed database using a geographic information system, use the accumulated data for student investigations in a wide variety of environmentally related courses, and facilitate similar approaches at other institutions. The project involves equipment acquisition; continuous monitoring of hydrology, water quality, and meteorology; and data collection and analysis in various undergraduate courses. This website is the homepage for the Burd Run Interdisciplinary Watershed Research Laboratory. Users can follow links to a project summary, watershed description and data, GIS data, research projects, curricular material, articles and maps and photos related to the laboratory.

But It's Just a Bottle of Water
Conditions of Use:
Read the Fine Print
Rating

Bottled water, popular among students, is big business even though issues surrounding it related to health and safety as well as its environmental impact have stirred up controversy. Designed for an introductory non-majors environmental science course, this discussion/dilemma case explores the environmental effects associated with the production, consumption, and recycling of bottled water while touching on health and safety issues. Students also learn about government regulations regarding the extraction of ground water and labeling of bottled water; recycling laws and how states circumvent the recycling process; and the economic and ecological costs of drinking bottled water.

This semester-long project uses the nitrogen budget to link campus operations with local ecology. Students can work independently or in groups to research the inputs, outputs and subsystem transfers of nitrogen on their campus. The data could be used to evaluate the effect of campus sustainability efforts, energy efficiency options, and other campus policies. This SERC Starting Point site includes learning goals, context for use, teaching tips and materials, assessment, and references.

Can Suminoe Oysters Save Chesapeake Bay?
Conditions of Use:
Read the Fine Print
Rating

This dilemma case explores the controversy over introducing non-native oysters to the Chesapeake Bay as a means of improving its ecological and economic health. Developed for use in an interdisciplinary doctoral program in energy and environmental studies, it could be adapted for undergraduate courses ranging from ecology and biology to political science and geography. The case introduces students to the various stakeholders and their positions from the point of view of a senator who must cast the deciding vote on whether or not to introduce Suminoe oysters (Crassostrea ariakensis) into the bay. Students read the case, then work in small groups to develop a stakeholder position, which they later role-play in class in a simulated public hearing.

Can You Catch the Water?
Conditions of Use:

Students construct three-dimensional models of water catchment basins using everyday objects to form hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human activities. Students discuss how engineers design structures that impact water collection, as well as systems that clean and distribute water.

Cartesian Diver
Conditions of Use:

This activity has students create a Cartesian diver, which will act in some ways like a submarine. Students will adjust the amount of air and water in an inverted test tube (the "diver") so that it at first barely floats in a water-filled bottle. Then, they will squeeze the closed bottle to create higher water pressure, causing the diver to sink. Releasing the bottle allows the diver to float again. Written instructions, a list of materials, and illustrations are included.

A Case of Innovation
Conditions of Use:

Rating

Students learn about power generation using river currents. A white paper is a focused analysis often used to describe how a technology solves a problem. In this literacy activity, students write a simplified version of a white paper on an alternative electrical power generation technology. In the process, they develop their critical thinking skills and become aware of the challenge and promise of technological innovation that engineers help to make possible. This activity is geared towards fifth grade and older students and computer capabilities are required. Some portions of the activity may be appropriate with younger students. CAPTION: Upper Left: Trey Taylor, President of Verdant Power, talks about green power with a New York City sixth-grade class. Lower Left: Verdant Power logo. Center: Verdant Power's turbine evaluation vessel in New York's East River. In the background is a conventional power plant. Upper Right: The propeller-like turbine can be raised and lowered from the platform of the turbine evaluation vessel. Lower Right: Near the East River, Mr. Taylor explains to the class how water currents can generate electric power.
