NASA CONNECT Tools of the Aeronautics Trade
In NASA CONNECT Tools of the Aeronautics Trade, students explore the U.S. Customary and Metric systems of measurement, understand how to convert units in both systems, and are introduced to the four forces of aerodynamics: lift, weight, drag and thrust. Students also investigate the tools and techniques used by NASA aeronautical engineers and scientists to measure lift and drag. Grades 4-8.
NASA CONNECT Data Analysis and Measurement: Dancing in the Night Sky
In NASA CONNECT Dancing in the Night Sky, students will learn about the Aurora Borealis or Northern Lights. They will learn the many legends and myths that have revolved around the aurora throughout the history of mankind. Students will also discover how NASA scientists and engineers use satellite technology to measure and analyze aurora data. They will see how Norwegian scientists apply the concepts of data analysis and measurement to study the Northern Lights by using ground-based instruments
Lecture on fieldwork in the Soviet Union, 1988-9
Public lecture given in October 1989 by Professor Ernest Gellner. He reflected on his year spent in the Soviet Union on the eve of the collapse of communism.,The lecture was given to a Cambridge Audience in the Rayleigh Lecture theatre in the Social and Political Sciences Faculty. Professor Gellner had flown in that morning from America. It was filmed, using a video 8 camera, by Humphrey Hinton. It was chaired by Dr. Alan Macfarlane. The video is unedited. The lecture lasts for about 65 minutes.

Anthropic Cyberspace: Defining Eletronic Space from First Principles
This paper proposes principles for the design of human-centered, anthropic cyberspaces. Starting with a brief examination of our cognitive use of space, it suggests that we address cyberspace as an extension of our mental space. The paper procedes with twelve concepts based on scientific and cultural observations with respect to individual cognition and social interaction. These concepts are general - not specific to any culture or technology in the accompanying arguments the author expands on t

Science In Focus: Energy
Interview with Stephen Connors about limited sources of energy and the importance of using renewable sources.,In this segment, the interviewee provides a brief overview of some sources of renewable energy that don't require "burning stuff", such as hydroelectric, solar, and wind power. He also mentions tidal and wave power. He indicates that wind and sun are diffuse so a lot of collection is required. This segment does not address the last sentence of this benchmark.
Science In Focus: Energy
Interview with Stephen Connors about limited sources of energy and the importance of using renewable sources.,In this segment, several renewable sources of energy are described as well as some of the advantages and disadvantages of each. The sources discussed in this segment are photovoltaics, wind power, biomass, geothermal, hydropower, nuclear power,tidal and wave power are mentioned but not discussed at length. He then makes the point of the necessity of acknowledging significant trade-offs
Case Studies in Science Education: Terez—Grade 4
Terez, a fourth-grade teacher, is developing an assessment strategy that is more student centered.,Terez is a teacher who is interested in using portfolios in her classroom. Different techniques are shown and discussed. Students are seen discussing and studying a few topics in Earth science, such as rocks and minerals, and weather and sky.
Science in Focus: Force in Motion: Workshop 6: "Force Against Force"
Magnets stick to other magnets and to metal objects made of iron or steel. How much force is required to break the attraction between two magnets? In this workshop, fourth-grade students explore ways to balance the force of magnetism against the force of gravity. A magnet placed in a cup on one side of a pan-balance is stuck to a stationary magnet beneath the cup. When enough washers are placed on the opposite side of the balance, the magnets will separate. Graphical analysis shows some unexpect

Applied Probability
Focuses on modeling, quantification, and analysis of uncertainty by teaching random variables, simple random processes and their probability distributions, Markov processes, limit theorems, elements of statistical inference, and decision making under uncertainty. This course extends the discrete probability learned in the discrete math class. It focuses on actual applications, and places little emphasis on proofs. A problem set based on identifying tumors using MRI (Magnetic Resonance Imaging) i

Linkage Mapping a Mutation in Arabidopsis
Since Alfred Sturtevant constructed the first genetic map of a Drosophilachromosome in 1913, new mutations have been mapped using his method of linkage analysis. Determining the map position of a new mutation -- and its corresponding gene -- consists of testing for linkage with a number of previously mapped genes or DNA markers. Linkage is the principle that the closer two genes or markers are located to one another on a chromosome, the greater the chance that they will be inherited together as
Bent's Old Fort National Historic Site's Learning Page
examines the people and construction of Bent's Fort, and the Santa Fe Trail. Built originally in 1833, this adobe fort became a center of trade with Indians and trappers. For much of its 16-year history, it was the only major permanent white settlement on the Santa Fe Trail. It provided explorers, adventurers, and the U.S. Army a place to get supplies, wagon repairs, livestock, good food, water, company, rest and protection in this vast Great American Desert.
