This activity is an introduction to the water cycle where students will use observation, drawing, writing, recording, questioning, and communication to understand the concept of condensation.
This lesson is an instructor demonstration that focuses specifically on two aspects of the water cycle: evaporation and condensation. This is a well described instructor led demonstration for introducing and exploring the water cycle.
Animated video of the different parts of the water cycle. Also includes some additional terms related to the water cycle.
Students use a thermal process approach to design, build and test a small-scale desalination plant that is capable of significantly removing the salt content from a saltwater solution. Students use a saltwater circuit to test the efficiency of their model desalination plant and learn how the water cycle is the basis for the thermal processes that drive their desalination plant.
This course, which examines ways of resolving conflicts over the allocation of water resources, is designed to raise student awareness of the state of freshwater resources globally and the need for more effective water governance. It builds on several case studies of transboundary water conflicts in different parts of the world while also helping students develop the negotiation and mediation skills they will need to resolve water disputes.
A report by the Natural Resources Defense Council, explores the water-energy connection through the topic of greenhouse gas emissions.
Students are asked to design methods to filter water using ordinary materials, while also considering their designs' material and cost efficiencies. They learn about the importance of water and its role in our everyday lives. They come to understand what must occur each day so that they can have clean water.
In this video segment adapted from NOVA, learn about an experiment investigating whether liquid water on Earth could have resulted from a massive planetary impact billions of years ago.
This take-home final exam asks students to demonstrate their improved skills in searching for sources (information literacy) and writing on freshwater science/society/policy intersections (science literacy), and author an essay themed on Water Optimism.

Students use a microcomputer connected to a conductivity probe to measure the total dissolved solids in local area water samples.

This is a field investigation in which students test water quality in 2-3 areas using their own testable question.
The course material emphasizes mathematical models for predicting distribution and fate of effluents discharged into lakes, reservoirs, rivers, estuaries, and oceans. It also focuses on formulation and structure of models as well as analytical and simple numerical solution techniques. Also discussed are the role of element cycles, such as oxygen, nitrogen, and phosphorus, as water quality indicators; offshore outfalls and diffusion; salinity intrusion in estuaries; and thermal stratification, eutrophication, and sedimentation processes in lakes and reservoirs. This course is a core requirement for the Environmental MEng program.
These 6 slides include descriptions of, photos of, formative assessment for, and extension reading for 4 water 'clean-up' strategies. These strategies are: fountain or bubbler oxygenation, wood chip bioreactors, reverse osmosis, and ion exchange resins.
I use it with water quality testing activities, and data analysis activities to meet standard:
HS LS 2-7: Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
HS LS 2-2: Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
HS LS 2-1: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
Standards about materials cycling in the environment can also be supported using the Nitrogen Cycle.
Students analyze local water chemistry by identifying and collecting local water samples, deciding upon questions they want to answer about their local water sources, and then performing simple water quality tests on their samples.

Just south of Atlantas busy Hartsfield-Jackson International Airport, Clayton County seems like an obvious place for metropolitan growth. But more homes and businesses mean a higher demand on the countys limited water supplies.
This portal, published by the University of Florida/Institute of Food and Agricultural Science (IFAS) Extension, offers a selection of links to information about water management issues. There is a 'Beginner's Guide to Water Management', which provides a basic introduction to the terminology and concepts used in water management. Other links access information on management in coastal waters, the impact of climate change on water resources, the use of stormwater as an alternative supply, wastewater management, and many others.
This subject is concerned with quantitative methods for analyzing large-scale water resource problems. Topics covered include the design and management of facilities for river basin development, flood control, water supply, groundwater remediation, and other activities related to water resources. Simulation models and optimization methods are often used to support analyses of water resource problems. In this subject we will be constructing simulation models with the MATLAB® programming language and solving numerical optimization problems with the GAMS optimization package.
This activity is a 3 part lab activity where students create a model of an area in a community. The students test how dirty water flows through their models observing where water is filtered or not. Using what was learned by the models, students will draw a community scene that has man made areas alongside areas that benefit groundwater filtration.
We refer to Earth as the \Blue Planet\" because of its abundance of liquid water; indeed, NASA's search for life on other planets starts with the search for water. While its importance for sustaining life is perhaps common knowledge, the extent to which we depend on water in every aspect of our everyday lives and activities is less obvious. Looking into the coming decades, the global need to decrease water stress and increase water quality is inescapable. In this course, you will explore water's impact on human society from investigating your own personal water usage to developing a water portfolio to addressing global water needs as human population centers and industrial development continue to grow."
In this video segment adapted from ZOOM, visit a water treatment plant and learn how water from a local reservoir is turned into drinking water.
