This is a five-activity module that explores the evidence for and impacts of melting glacial ice, with resources from major institutions and scientists who study glaciers -- primarily in Arctic areas. The suite of activities includes both glaciers and melting ice, as well as the impact of melt water downstream. Each activity follows the 5E model of Engagement, Exploration, Explanation, Elaboration, and Evaluation.

Discussion of the properties of water that make it essential to life as we know it: polarity, "universal" solvent, high heat capacity, high heat of vaporization, cohesion, adhesion and lower density when frozen.

Water covers 71% of the earth's surface-does it get the instructional time it deserves in your busy curriculum? Students wade right in to the study of bodies of water as they read and discuss science trade books and work together to develop Readers Theater scripts based on selected titles.

Learn about urban water services, focusing on conventional technologies for drinking water treatment. This course focuses on conventional technologies for drinking water treatment. Unit processes, involved in the treatment chain, are discussed as well as the physical, chemical and biological processes involved. The emphasis is on the effect of treatment on water quality and the dimensions of the unit processes in the treatment chain. After the course one should be able to recognise the process units, describe their function, and make basic calculations for a preliminary design of a drinking water treatment plant.

This session presents an overview of the association between water, sanitation, hygiene and human health. A particular focus upon transmission and treatment of diarrhea disease among small children. Other diseases given particular priority in the presentation include Hepatitis A and E viruses and bacteria that cause cholera or typhoid fever. Likewise, the importance of water-washed diseases, especially infectious skin and eye diseases, such as scabies and trachoma are presented. The preventive actions needed to reduce the burden of the various infectious diseases associated with water, sanitation and hygiene will be introduced.

This session will expand the student´s knowledge about human health and quality of life in the context of global and local ecology. Examples will be provided on how environmental management and development influence human health. The session provide an overview of the disease burden attributable to the environment, and much of this burden is placed across different geographical regions of the world. Examples will be presented on the impacts of poor quality water, insufficient access to water, lack of appropriate sanitation and poor personal hygiene. Other examples of environmental health factors included relate to reduced forest cover, unsustainable agricultural production systems, climate change, and poor management of natural resources that significantly influence livelihood, food security and migration patterns.

What determines our health? Why does life expectancy differ so much from country to country, or even from one group to another in the same country? Well, there is no easy answer to these questions. There are many factors that play a part in determining the well-being of the population, or even of an individual. In global health, we call these factors determinants of health. Determinants of health interact with each other, and influence our health status is in numerous ways, in turn influencing our well-being, morbidity, mortality, and life expectancy. As you already know, the first and most important health determinant is income. Income of an individual or a household, but also income of the country a person lives in. Other important health determinants are education, access to water, diet, environment and many more. In this presentation we will look closer at how health determinants determine an individual’s health, and how different health determinants interact with each other.

During this course, we will be exploring basic questions of architecture through several short design exercises. Working with many different media, students will discover the interrelationship of architecture and its related disciplines, such as structures, sustainability, architectural history and the visual arts. Each problem will focus on one of these disciplines and one exploration and presentation technique.

Students are presented with examples of the types of problems that environmental engineers solve, specifically focusing on water quality issues. Topics include the importance of clean water, the scarcity of fresh water, tap water contamination sources, and ways environmental engineers treat contaminated water.

Explores the entire Water Systems Technology program, which includes the class and degree offerings. Reviews the State Water Resources Control Board Division of Drinking Water operator certification requirements (California). Various topics include water supply, water quality, drinking water treatment and distribution, wastewater and recycled water and other related topics.

This is an introduction to the fascinated multidisciplinary world of water, sanitation, and hygiene (WASH). An area relevant due to the 1,5 million people annually dying of WASH-related disease, but also highly relevant during any emergency, whether it is a cholera outbreak in the slums of Dhaka Bangladesh, drought and water shortage in Kenya or hygiene-related virus outbreaks anywhere on the globe. The course ties theories of engineering, anthropology, public health, epidemiology, microbiology, disaster management, etc. with practical exercises to provide the student with the multifaceted background knowledge needed to be able to respond in an emergency actively. The course Water and sanitation in Emergencies started as a response to the Tsunami in 2004 and is now an independent elective course under the world-renowned Master of Disaster Management program, http://www.mdma.ku.dk, at University of Copenhagen.

This is an introductory lab for Environmental Science, investigating the bulk density of soil and water holding capacity.

Students observe how water acts differently when placed on hydrophilic and hydrophobic surfaces. They determine which coatings are best to cause surfaces to shed water quickly or reduce the "fogging" caused by condensation.

This article highlights resources that can be used to supplement lessons on extreme weather, including games and video clips. The article appears in the free, online magazine for K-Grade 5 teachers Beyond Weather and the Water Cycle. The magazine focuses on the essential principles of climate science.

In this activity, students conduct an investigation to purify water. They engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment. Through this activity and its associated lesson, student teams follow the steps of the engineering design process related to water treatment, as done by practicing engineers, including constructing and testing their designs.

Clean and purified drinking water is a basic human need and over ¾ of the Earth’s human population has the luxury of having it piped directly into their homes. Unfortunately, that leaves almost 2 billion people worldwide where access to clean water is questionable. This unit will help students understand the risks involved with drinking untreated water and engage them in an engineering project to produce a means of filtering water to make it less risky. The beginning of this unit is designed to first help students understand the risks of drinking dirty water by introducing them to the world of microbial pathogens. Students will learn about some of the most common bacteria, viruses, and protozoa that can be lurking in a potential drinking water source. Then students will learn the basics of water treatment and how water treatment has evolved over the past thousand years. Students will use this knowledge to finally construct and test a water filter of their own design.

The unit was written in partnership with Dr. Jordan Peccia, a professor of Environmental Engineering at Yale University. It is designed for elementary students as young as third grade, but the concept and strategies involved can easily be adapted to learners of any age.
