This webpage is an overview of significant figures and their use in scientific notation. A chemistry tutor in the College of Math and Sciences at a public university developed this overview as one of several study aids for undergraduate chemistry students.
This set of online oceanography activities helps students learn about ocean waves and El Nino-Southern Oscillation (ENSO). The wave module addresses wave anatomy, global and local waves and their relationship to wind, and the properties of tsunamis. Activities in the ENSO module include simple calculations, discovery learning, satellite imagery, simulations, animations and drawings to present relationships between atmospheric and oceanic processes. Multiple choice self-tests are included. Provid

It is intended to give you skills and competences that you need to be a successful job searcher. It explores, for example, essential job search skills and approaches that will help you to compete in the changing la
Health Effects of Toxic Organic Compounds from Coal
This USGS fact sheet summarizes the occurrence of Balkan Endemic Nephropathy, a serious kidney disease that occurs only in tributary valleys of the Danube River in Romania, Bulgaria, and the former Yugoslavia. There is a close correspondence between the location of affected villages and the occurrence of local coal deposits.
Finding Common Ground
Finding common ground helps students make informed decisions to conserve temperate forests in the United States and central China, habitat of the endangered giant panda. Through classroom activities, on-line simulations, and field investigations students learn about the important role temperate forests play in local and global ecosystems. Action steps culminate in a Class Conservation Action Plan. In the course of this curriculum students locate the biome in which they live, explore a local habi
This San Diego Natural History Museum interactive website, designed specifically for kids, explores living lights and the chemistry of bioluminescence. It includes links to informational pages and facts about bioluminescence, a quiz and word search game, detailed glossary, and links to related websites. Java is required to fully access the activities associated with this page.
Entrepreneurship Consulting and Analysis
This course provides students an opportunity to practice action learning. Many instructors are advocates of action learning because they believe students can learn by doing. In this course, students will complete a project for a local entrepreneur. The project may be highly specialized or comprehensive in nature, depending upon the needs of the business.
Understanding Your Water
Over two class periods, you will be guiding your students through the basics of water treatment -- both tap water treatment and sewage (or wastewater) treatment. To prepare for the lessons on the treatment process, the students will be researching where their drinking water comes from and where their wastewater goes once it goes down the drain for homework. After learning about their local water treatment and traditional tap water and sewage treatment processes, students will watch the NewsHour
Reference Resources: Being a Good Detective
Students become familiar with a variety of reference resources when seeking information. These sources include atlases, almanacs, dictionaries, encyclopedias, thesauri, online search engines for the Internet, and online library card catalogs.
Lecture 25 - 5/27/2009
Phylogenetic Investigator (PI) is a software package designed to facilitate creative problem-solving in phylogenetic analysis for the purpose of teaching and learning phylogenetic inference. Users can identify characters and states, polarize characters, and engage in directed-search phylogenetic tree construction. PI also allows the user to * make inferences and represent them one step at a time * vary representational features of their trees (such as angle of divergence and time betwee
Envirofacts Data Warehouse
The Envirofacts Data Warehouse website provides access to several EPA databases that offer information about environmental activities that may affect air, water, and land anywhere in the United States. Users can search a pre-assembled sampling of information available pertaining to a specific area, or choose a topic for more in-depth information about a specific locale.
Foto: Modernity in Central Europe, 1918-1945
During and directly after World War I, four great empires (Germany, Austro-Hungary, Russia, and the Ottomans) crumbled precipitously, to be replaced by more than one dozen fledgling nation-states. The largely agrarian, in some cases semifeudal, societies of central Europe were thrust nearly overnight into crises of civil war, unemployment, or inflation — and beyond these crises into a world propelled by mass media and consumer economies. Becoming modern was attractive but also anxiety-provokin
Where Are the MDGs?
By investigating the coverage of the Millennium Development Goals in the media, students learn about both the local and global presence of development issues, as well as gain an introduction to the way the media represents these issues in different parts of the world.
Take a Technology Inventory
This activity prepares students to watch the film, "Local Voices, Global Visions," by having them examine the presence of technology in their own lives. Students should be familiar with the use of spreadsheets and have a basic working definition of information and communication technology (ICT), using the Understanding page or from their own initial research on the subject. This activity is part of a series of lessons surrounding the film, "Local Voices, Global Visions."
Spill Tools is a collection of three tools you can use to assess how effectively you can recover, remove, or disperse spilled oil using: - mechanical equipment, such as skimmers, to remove oil from the sea surface. - in situ burning, to burn off freshly spilled oil. - chemical dispersants, to disperse the spilled oil throughout the water column. Spill Tools was designed to help you to complete tasks like: - selecting and staging response equipment, such as skimmers, fire boom, and dispersant

Dust Bowl Migration
In 1931, a severe drought hit the Southern and Midwestern plains. As crops died and winds picked up, dust storms began. As the "Dust Bowl" photograph shows, crops literally blew away in "black blizzards" as years of poor farming practices and over-cultivation combined with the lack of rain. By 1934, 75% of the United States was severely affected by this terrible drought.The one-two punch of economic depression and bad weather put many farmers out of business. In the early 1930s, thousands of Dus
The people who came to California in search of gold were faced with the threat of disaster in every step of their journey. Many came by ship, even though shipwrecks were commonplace ? one set of lithographs depicts four shipwrecks that occurred within 60 days. Earthquakes were another fact of life in California. Sensational newspaper illustrations like "Earth Quakey Times," and photographs showing buildings in shambles, helped build the state's reputation as an "earthquake capital." Earthquakes
