Earth Exploration Toolbook Chapter: Measuring Distance and Area in Satellite Images
Users download and analyze MODIS imagery from 2001 and 2003 to quantify the shrinking of the Aral Sea. The chapter steps users through downloading, installing, and measuring with ImageJ, a freely available image analysis program. Users employ the software to set the spatial calibration of an image, then select and measure distances directly from the image. Measurement results are reported in real-world units. Users also select, measure, and compare the area covered by the sea in three time-serie
HazDat, the Agency for Toxic Substances and Disease Registry's (ATSDR) Hazardous Substance Release/Health Effects Database, is the scientific and administrative database developed to provide access to information on the release of hazardous substances from Superfund sites or from emergency events and on the effects of hazardous substances on the health of human populations. The following information is included in HazDat: site characteristics, activities and site events, contaminants found, cont
In molecular physics it is recognized that there is a coupling of rotational and vibrational energy-levels. In molecular physics rotational-vibrational coupling is also called rovibronic coupling and Coriolis coupling. The physics of actual diatomic molecules is more complicated than the example in this animation, but because of its simplicity the animation is useful for illustrating the basic principles.
Introduction to Biology
This introductory course defines biology and its relationship to other sciences. It examines the overarching theories of life from biological research and also explores the fundamental concepts and principles of the study of living organisms and their interaction with the environment. Learners will examine how life is organized into hierarchical levels; how living organisms use and produce energy; how life grows, develops, and reproduces; how life responds to the environment to maintain internal
"Project Management, Spring 2009"
"1.040 Project Management focuses on the management and implementation of construction projects, primarily infrastructure projects. A project refers to a temporary piece of work undertaken to create a unique product or service. Whereas operations are continuous and repeating, projects are finite and have an end date. Projects bring form or function to ideas or need. Some notable projects include the Manhattan Project (developing the first nuclear weapon); the Human Genome Project (mapping the hu

"Cutting a New Path": A World War II Navy Nurse Fights Sexism in the Military
In World War II soldiers, sailors, nurses, and airmen often found themselves thrown together with fellow Americans whose experiences and backgrounds were drastically different from their own. Racial segregation was an official policy of the War Department, but gender discrimination was a subtler, if no less troublesome, social constraint. Doris Brander, who enlisted shortly after Pearl Harbor in the navy's Women's Auxiliary Voluntary Expeditionary Service (WAVES), felt that she and her fellow WA
Speaking up for deaf education
Jason Lestina developed a software program called Animation Speaks Louder aimed at addressing deaf education in the science, technology, engineering and math disciplines. Now, Jason is working on another tool that will be used to teach math using the same program.
Plate Tectonic Movement Visualizations
This collection provides a wide array of visual resources and supporting material about plate tectonic movements. Visualizations include simple animations, GIS-based animated maps, paleogeographic maps and globes, and numerous illustrations and photos. This collection is not exhaustive but does represent some of the best sources for teaching. Resources can be incorporated into lectures, labs, or other activities.
What in the World Is That?
This site examines 16 inventions: the submarine, battery radio, cotton gin, reaper, electron microscope, telephone, gramophone, telecommunication cable, snow gauge, ornithopter, airphibian, and others.
Bill of Rights
On 12 September 1787, during the final days of the Constitutional Convention, George Mason of Virginia expressed the desire that the Constitution be prefaced by a Bill of Rights. Elbridge Gerry of Massachusetts proposed a motion to form a committee to incorporate such a declaration of rights; however the motion was defeated. This lesson examines the First Congress's addition of a Bill of Rights as the first ten amendments to the Constitution.
Tracking Down the Real Billy the Kid
This lesson relates to the westward movement in the United States in the late nineteenth and early twentieth centuries.
