Effects of Human Activities on the Interaction of Ground and Surface Water
No full textThis article discusses the effects of human activities on the interaction of ground water and surface water. Produced by the United States Geological Survey (USGS), this site provides solid textual content along with stunning visuals which work well together in conjunction
Understanding Methicillin-Resistant Staphylococcus aureus
No full textBioEd Online is an âeducational resource for educators, students, and parentsâ from the Baylor College of Medicine. This is an excellent place to find educational materials and current information in the field of biology. The âHot Topicsâ section of this site focus on current events and issues in biology that are âreceiving national attention.â This site, created by Mary Pat Bolton, MA, RD, LD, contains a brief discussion of Methicillin-Resistant Staphylococcus aureus (MRSA), commonly known as a "staph" infection. The article includes background information on the bacteria as well as information about how people become infected with MRSA, how it is treated, and how it can be prevented. In addition, the site includes links to references and further reading. Be sure to check out the related slide set, âUnderstanding Methicillin-Resistant Staphylococcus aureus." The slide show can be easily manipulated for use in the classroom along with the other resources provided in this âHot Topicâ from BioEd Online
Weather Forecast Models
No full textWeather Forecast Models from the NOAA, provides links to sites posting output from many of their numerical models. These models attempt to simulate the state of the atmosphere at various times in the future
Cornell NanoScale Science and Technology Facility
No full textThe Cornell NanoScale Science & Technology Facility (CNF) is a national user facility that supports a broad range of nanoscale science and technology projects by providing state-of-the-art resources coupled with expert staff support. 2007 marks our 30th year in operation. Research at CNF encompasses physical sciences, engineering, and life sciences, and has a strong inter-disciplinary emphasis. Over 700 users per year (50% of whom come from outside Cornell) use the fabrication, synthesis, computation, characterization, and integration resources of CNF to build structures, devices, and systems from atomic to complex length-scales
Circuits and Electronics
No full text6.002 Circuits and Electronics is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. 6.002 is in the core of department subjects required for all undergraduates in EECS. The course introduces the fundamentals of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage elements; dynamics of first- and second-order networks; design in the time and frequency domains; and analog and digital circuits and applications. Design and lab exercises are also significant components of the course
Rutherford Scattering
No full textHow did Rutherford figure out the structure of the atomic nucleus without looking at it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core. This simulation of a Rutherford Scattering is from the Physics Education Technology website of University of Colorado. Included are links to related topics and additional ideas and activities for teachers to use
WorldWide Telescope
No full textThe WorldWide Telescope (WWT) is a Web 2.0 visualization software environment that enables your computer to function as a virtual telescope. This brings together imagery from the best ground and space-based telescopes in the world for a seamless exploration of the universe. The site offers narrated tours from astronomers and educators. An installation of the telescope must be performed before the website if functional. Additionally, the program require a Windows based operating system
Make a Robotic Snap-O-Lantern!
No full textThe Snap-O-Lantern is a robotic mini-pumpkin. Normally, it just sits there, in disguise as a boring old pumpkin. But, every twenty seconds he comes to life. His LED eyes turn on, his jaw slowly opens, and then SNAPS shut-- and he goes back into stealth mode.What's inside? A small hobby servo motor, driven by an AVR microcontroller. This is a minimal microcontroller project, and is very straightforward if you happen to already have a setup for programming one. We'll walk through the carving, setup, programming, and electronics. This is an open-source project, one of the world's first "gpl-o-lanterns"; source code is provided. This is great for a student and/or class project
Standardizing
No full textThis page, created by Statisical Literacy.com, contains a short article on Simpson'ÂÂs Paradox with an example of how standardizing changes the results. It also contains links to other "real world" articles on Simpson'ÂÂs Paradox, including a newspaper article illustrating that this topic is timely. The site features a few graphs to help better represent the concept. Overall, this is a brief but useful explanation of this concept
Anatomy of a Wildfire - The B&B Complex Fires
No full textThis module is the third in the Fire Ecology and Management Series. The module is designed for courses that support natural resource disciplines such as Forestry, Wildlife and Environmental Science. Although the module can be taught independently, faculty should consider teaching as part of the series. Specifically, the modules The Ecological Role of Fire and Historical Fire Regimes and their Application to Forest Management are designed to prepare students for the activities in this Anatomy of a Wildfire â B&B Complex Fire module. In this lecture-based module the B&B Complex Fire in central Oregon is examined as a case study to introduce the basics of wildfire behavior in the context of historical fire regimes. A PowerPoint presentation describes recent changes in fire frequency and intensity, how fire histories are determined, wildfire progression, methods for post-fire assessment and post-fire recovery and rehabilitation
