Resistan is a mechanistic simulation model of the process of selection of fungicide-resistant biotypes of a hypothetical fungal pathogen of a hypothetical crop. The fungus is a polycyclic organism with many generations per season. There is no genetic component in this simulator. Reproduction is assumed to be asexual. A small proportion of the initial inoculum is designated as the fungicide-resistant biotype at the start of the season, and the response of that population to various fungicide spr
Phylogenetic Investigator (PI) is a software package designed to facilitate creative problem-solving in phylogenetic analysis for the purpose of teaching and learning phylogenetic inference. Users can identify characters and states, polarize characters, and engage in directed-search phylogenetic tree construction. PI also allows the user to * make inferences and represent them one step at a time * vary representational features of their trees (such as angle of divergence and time betwee

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.

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: 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
