Refraction and the Ray Model of Light
No full textCreated by Tom Henderson of the Physics Classroom.com, this item is a chapter in a beginning physics tutorial. It explores the conceptual and mathematical principles governing the bending of waves as they cross the boundary between two media. The ray nature of light is used to explain the behavior of light as it refracts, or bends, at planar and curved surfaces. Refraction principles are combined with ray diagrams to explain how lenses produce images. This is one subset of a much larger collection of physics lessons and other materials
Neptune
No full textThis site focuses on the planet Neptune. Some topics discussed include: the planet's atmosphere, interior, and surface, its moons and rings, space missions, its magnetosphere, myths, and the latest news from Neptune. Also includes several photographs and links to related websites. The site is also available in Spanish
Biotechnology; Precision Agriculture; Working with Medical Electronics
No full textThe ATETV project delivers web-based videos to connect students to careers in advanced technology. This episode of ATETV focuses on Biotechnology, Agricultural Sciences, and Medical Electronics. The video looks at the process and advantages of transferring from two-year colleges onto a four-year institution. This video also showcases Agricultural Science and the impact that students can have on that field. It can be viewed whole or in three segments: "Community College Biotechnology Programs," "Agricultural Technology," and "Working with Medical Electronics." The running time for the full episode is 9:47
USGS Water Resources: Water Use in the United States
No full textThis portal, published by the United States Geological Survey (USGS) Water Resources Program, provides access to information on national water use. There are links to a set of reports and data on U.S. water use from 1985 to 2000. Other links access a map comparison of consumptive use and renewable water supply by water-resources region, introductory material on the National Water-Use Information Program, a bibliography, and a handbook for collecting water use data
STEM Guitar Project
No full textThis ATE professional development project is a collaboration between STEM faculty teams from Butler County Community College (Butler, PA), Purdue University (West Lafayette, IN), Sinclair Community College (Dayton, OH), Ventura College (Ventura, CA), College of the Redwoods (Eureka, Ca.), as well as high school STEM faculty in each of the states involved. Faculty teams at the respective locations are working together to design, build, and analyze solid body electric guitars as a means of learning applied concepts of science, technology, engineering, mathematics, and as a means of understanding product lifecycle management. This experience is providing teachers and students an accurate simulation of the collaborative design and rapid manufacturing processes routinely used in business and industry. Over 150 STEM faculty members from high schools and community colleges are participating in an intense five-day Summer Professional Development Program and are having extensive academic year follow-up activities. The teacher participants are using these processes and simulations in their classrooms to enhance the STEM laboratory learning experience. Nearly 5000 students are learning about cross-disciplinary STEM problem solving that is becoming increasingly important for new design technicians to experience.On the site, visitors can find curriculum materials including classroom tools and information on guitar fabrication. There are also details of upcoming workshops and professional development opportunities. In the Storefront section, visitors can learn about how to purchase a guitar kit
Environmental Engineering; Process Technology; Information Security
No full textThe ATETV project delivers web-based videos to connect students to careers in advanced technology. This episode of ATETV examines three important and growing technological fields: environmental engineering, process technology, and information security. The video can be viewed whole or in three segments: "Environmental Engineering," "Process Technology," and "Information Security." The running time for the full episode is 9:22
Cooking Under Pressure
No full textThis case study aims to connect basic chemistry concepts with real world examples in daily life. The topics covered include boiling point, chemical reaction rate, and the conservation of energy. The lesson is intended for high school and lower level undergraduate students. The case study and teaching notes may be downloaded in PDF format. The site also includes a section for instructor feedback where general comments may be read and contributed
Electrochemical Education
No full textThe purpose of this site is to collect in one location resources useful to educators attempting to incorporate modern electrochemical techniques into the undergraduate chemistry curriculum. Contains links to material on experiments, equipment, proposal writing, etc
Molecular Structure and Dynamics by NMR Spectroscopy
No full textThis site provides PowerPoint slides for a lecture for a graduate-level course in NMR spectroscopy. The slides include useful animations which help to demonstrate the concepts described. While the casual student may find it hard to follow everything on the slides without an accompanying lecture, the files should be very useful for advanced students or educators putting together similar courses
How Hydropower Plants Work
No full textWorldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable Energy Laboratory. There are more than 2,000 hydropower plants operating in the United States, making hydropower the country's largest renewable energy source. In this article, we'll take a look at how falling water creates energy and learn about the hydrologic cycle that creates the water flow essential for hydropower. You will also get a glimpse at one unique application of hydropower that may affect your daily lif
