You may subscribe to receive weekly news features by e-mail or via RSS feed . August 2012 Early attention to design makes employee parking structure a model of low energy use. July 2012 1,300 solar panels turn sunlight into electricity on Alcatraz Island in San Francisco Bay. NREL is working with industry to find ways to reduce the energy intensity of large hospitals, schools, and retail buildings by 50%. From humble beginnings, NREL's expanding campus is a model of research, deployment, and sustainability. June 2012 Device combines infrared camera with GPS and software to identify failing receivers at concentrating solar power plants. Growing renewable butanol refiner demonstrates its process for a future scale-up of the drop-in petroleum replacement.

The K–12 Center at ETS: Invitational Research Symposium on Science Assessment September 24–25, 2013 Washington, D.C. This two-day research meeting brought together more than 250 leaders in science, education and assessment from academia, industry and government, including teams from some 30 states, to explore the skills and competencies called for in the Next Generation Science Standards (NGSS) and the measurement challenges and opportunities they pose. Commissioned papers were presented on the design of both summative tasks and formative systems that adhere to the vision of instruction underlying the NGSS. In addition, the policy and practice work ahead, including the difficult trade-offs to be made in the designs of comprehensive science assessment systems, were discussed. The closing two sessions were made available on the web in real time and the videos can be viewed below. View the Agenda (PDF) Summary Report by Rodger W. Presentation Materials
Posters Scientific Posters Posters are a special type of presentation. When well designed, they are not simply journal papers pasted onto boards. Nor are they mounted sets of presentation slides. Rather, posters, when effectively designed, are something in between. The purpose of scientific posters is to present work to an audience who is walking through a hallway or exhibit. Figure 1. Figure 2. Figure 3. So then what makes for an effective poster? First, the title of an effective poster should quickly orient the audience. Second, the poster should quickly orient the audience to the subject and purpose. Third, the specific sections such as the results should be easy to locate on the poster.Once readers recognize what the work is, they decide how much energy to invest into the poster. Figure 2 presents a poster that quickly orients the audience to the topic of the work. References Alley, Michael, The Craft of Scientific Presentations, 2nd ed. Lamancusa, John, Jens E.
Hydroelectric Power: How it works, USGS Water-Science School So just how do we get electricity from water? Actually, hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller-like piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same. Take a look at this diagram (courtesy of the Tennessee Valley Authority) of a hydroelectric power plant to see the details: The theory is to build a dam on a large river that has a large drop in elevation (there are not many hydroelectric plants in Kansas or Florida). This diagram of a hydroelectric generator is courtesy of U.S. As to how this generator works, the Corps of Engineers explains it this way: "A hydraulic turbine converts the energy of flowing water into mechanical energy.

Welcome to NESTA | NESTA Common Misconceptions About Rocks and Minerals — Rocks and Minerals Although the research base for geologic misconceptions is not as extensive as that of other disciplines within earth and space science, it is clear that students and teachers alike hold a wide range of incorrect ideas about rocks, minerals, and the rock cycle. To promote accurate scientific instruction, it is important that teachers are cognizant of their own understanding and seek to continually improve their content knowledge. Formative assessment can provide a great deal of insight into student thinking before, during, and after instruction. Finally, teachers should be metacognitive practitioners and reflect on how their methods of instruction may lead to the formation or strengthening of existing misconceptions. Geologic Misconceptions Geologic misconceptions can take many forms – the language used to define and describe specimens, relevant properties for classification, the rock cycle, and geologic time.

Harvard STEM Teaching Videos Posted on May 28th, 2013 by Mary Lord Looking for a way to make probability come to life in your multicultural math class and assess which students “got it?” How about a fun activity that gives high-school students a hands-on feel for fundamental calculus concepts and also meets state content standards? The Harvard-Smithsonian Center for for Astrophysics has compiled a digital video library full of curriculum-enhancing lessons, assessment tools, and case studies - all developed and used by teachers in their classrooms. These “Videos to Enhance Understanding and Teaching of K-12 Learning Goals,” as the project is called, feature: • Clinical Interviews of Student Ideas • Demonstrations of Phenomena • Case Studies of Instruction or Research • Interviews with Experts • Correlations to state and national curriculum standards Clips can be searched for in a variety of ways. The collection of 1,017 movies includes a range of topics. Among the “What’s the Point?”
Elementary Curriculum Resources Energy Infobooks are the resource for many NEED activities and include an introduction to energy, information on major sources of energy, new technologies, energy conservation, electricity, climate change, and other energy information. They are available on four reading levels and are revised and updated annually.
