Between 70 and 75% of the Earth's surface is covered with water and there exists still more water in the atmosphere and underground in aquifers. In this lesson, students learn about water bodies on the planet Earth and their various uses and qualities. They will learn about several ways that engineers are working to maintain and conserve water sources. They will also think about their role in water conservation.

Learn how friction causes a material to heat up and melt. Rub two objects together and they heat up. When one reaches the melting temperature, particles break free as the material melts away. Arabic Language.

This series of 5 word problems lead up to the final problem. Most students should be able to answer the first two questions without too much difficulty. The decimal numbers may cause some students trouble, but if they make a drawing of the road that the girls are riding on, and their positions at the different times, it may help. The third question has a bit of a challenge in that students won't land on the exact meeting time by making a table with distance values every hour. The fourth question addresses a useful concept for problems involving objects moving at different speeds which may be new to sixth grade students.

From the earliest days of settlement and migration, the people of North America have relied on maps and mapping to understand their environment and place within it. Maps have helped Americans prospect investments, comprehend war, and plan leisure in places unknown. As Americans have used maps to explore the U.S., capitalize on its resources, and displace its Native peoples, maps have shaped American cultural ideas about travel, place, and ownership. This exhibit explores the cultural and historic impact of mapping through four specific moments in American history: migration along the Oregon Trail, the rise of the lumber industry, the Civil War, and the popularization of the automobile and individual tourism. It concludes with a look at maps in the age of computers, the Internet, and beyond. These moments demonstrate the influence maps have had over how Americans imagine, exploit, and interact with national geographies and local places. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students in Professor Helene Williams's capstone course at the Information School at the University of Washington: Greg Bem, Kili Bergau, Emily Felt, and Jessica Blanchard. Additional revisions and selections made by Greg Bem.

In 1845 Frederick Douglass published what was to be the first of his three autobiographies: the Narrative of the Life of Frederick Douglass, an American Slave, Written by Himself.  As the title suggests, Douglass wished not only to highlight the irony that a land founded on freedom would permit slavery to exist within its midst, but also to establish that he, an American slave with no formal education, was the sole author of the work.

In this activity, students will use a tutorial on the U.S. Environmental Protection Agency's website to learn about how surface water is treated to make it safe to drink.

This book is for students who have studied Modern Standard Arabic (MSA) for one year or more and would like to learn colloquial Arabic basics using their knowledge of MSA. It aims at transitioning learners from Novice Mid level to Intermediate Low through presenting situations useful for living in an Arab country. The book has several features including hyperlinks, practice dialogues with open answers, cultural tips, and more.

The objective of this course is to introduce large-scale atomistic modeling techniques and highlight its importance for solving problems in modern engineering sciences. We demonstrate how atomistic modeling can be used to understand how materials fail under extreme loading, involving unfolding of proteins and propagation of cracks.

Explores the impact of the printing press upon European politics and culture during the first several centuries after Gutenberg and compares these changes with the possibilities and problems inherent in contemporary electronic technologies of the word. Assignments include formal essays and online projects. There has been much discussion in recent years, on this campus and elsewhere, about the death of the book. Digitization and various forms of electronic media, some critics say, are rendering the printed text as obsolete as the writing quill. In this subject, we will examine the claims for and against the demise of the book, but we will also supplement these arguments with an historical perspective they lack: we will examine texts, printing technologies, and reading communities from roughly 1450 to the present. We will begin with the theoretical and historical overviews of Walter Ong and Elizabeth Eisenstein, after which we will study specific cases such as English chapbooks, Inkan knotted and dyed strings, late nineteenth-century recording devices, and newspapers online today. We will also visit a rare book library and make a poster on a hand-set printing press.

This lesson focuses on the biggest problem faced by any young programmer - i.e. the LOGIC BUILDING required while solving a particular problem. With programming, the solution to a particular problem lies in the head, but one is unable to convert it into a computer program. This is because the thought processes of a human are much faster than the sense of observation. If this thought process could be slowed down, logic to solve a programming problem could be found very easily. This lesson focuses on converting this psychological thought process in a step-by -step logic fashion that a computer program can understand. This lesson is recorded in a kitchen where the basic programming concepts are taught by giving examples from the process of making a mango milk shake. This lesson teaches the 4 following techniques: 1) Swapping two variables by swapping a glass of milk with a glass of crushed ice; 2) Finding max from an array by finding the biggest mango; 3) Sorting an array by arranging the jars; and 4) Understanding the concept of a function, parameters and return type by comparing it with the blender/juicer. The lesson targets those students who know the syntax of programming in any language (C or GWBASIC preferred), but are unable to build the logic for a program. It can be taught in a class of 45 to 50 minutes.

This lesson is also available in Mandarin Chinese.

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. Generally constructed of silicon, photovoltaic cells contain a large number of electrons BUT they can be thought of as "frozen" in their natural state. A source of energy is required to "free" these electrons if we wish to create current. Light from the sun provides this energy. This will lead to the principle of "Conservation of Energy." Finally, with a basic understanding of the circuits through Ohm's law, students will see how the energy from the sun can be used to power everyday items, including vehicles. This lesson utilizes the engineering design activity of building a solar car to help students learn these concepts.

Students will learn about the water cycle, watersheds, and specifically, the watershed that feeds Springfield, Oregon. After analyzing drought maps, reading news reports, and seeing images and videos, students will realize that drought is a real life concern. Students, as concerned citizens, will create a water collection device, at first on a small scale, and then a true to life water collection system to help re- purpose rainwater in our garden area.

Examines interactions across the Eurasian continent between Russians, Chinese, Mongolian nomads, and Turkic oasis dwellers during the last millennium and a half. As empires rose and fell, religions, trade, and war flowed back and forth continuously across this vast space. Britain and Russia competed for power over Eurasia in the "Great Game" of geopolitics in the nineteenth century, just as China, Russia, and others did in the twentieth century. Today, the fall of the Soviet Union and China's reforms have opened new opportunities for cultural interaction. Topics include: the religious traditions of Central Asian Islam, Buddhism, Christianity, and Confucianism; caravans and travelers like Marco Polo and Rabban Sauma, the first Chinese to travel to the West; and nomadic conquest and imperialist competition, past and present. Source materials include primary documents, travelogues, films, music, and museum visits.
