Magnetism 6: Magnetic Field Due to Current
See how a wire carrying a current creates a magnetic field. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 09:42.
How Changes in Earth's Magnetic Field and Ionosphere Affect Us - Part 4
Part 4 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Anya Strømme – EISCAT/SRI International. She’s working with very high power radar to study the aurora borealis which are better observed at higher latitudes. She’s studying particles coming into the atmosphere, heating it, generating currents—this is where our satellites fly…this impacts tv reception, GPS, cell phones in a much more dramatic way than we can imagine. Run time 03:16.
How do changes in Earth's magnetic field and ionosphere affect us?
Part 1 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Bob McCoy – Office of Naval Research. Storms and variations in the ionosphere impact Navy instruments, e.g, Suns storms (disturbances) can degrade GPS affecting ship navigation, airplanes, and all kinds of communication and transportation on Earth. Dish TV and satellite operations are also disrupted or impacted by this. Talks about the fun of flying rockets and studying the data to make new discoveries
How do changes in Earth's magnetic field and ionosphere affect us? - Part 2
Part 2 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Gang Lu – National Center for Atmosphere Research. Talks about her data analysis of radar and satellite data. Talks about the continuing exploration of all that is to be investigated in exploring the fine particle changes in the aurora. Run time 03:38.
How do changes in Earth's magnetic field and ionosphere affect us? - Part 3
Part 3 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Kyle Johnson – University of Colorado. Talks about meteor entry into the atmosphere (large flaming balls and little pieces of sand) leaving a trail visible on radar. They use the meteor trails to model affects on the lower atmosphere. Our daily lives depend on the Sun so it’s important in understanding the nature of that energy balance; it’s not a direct connection, but its all connected. He had al
MALCOLM X: THE HOUSE NEGRO AND THE FIELD NEGRO
In this video Malcolm X is giving a speech explaining the difference that he sees between the "house negro" and the "field negro". Malcolm X is an amazing speaker, and this video showcases his talents.
Virtual Field Trip to The Money Museum
Join Amanda for a virtual field trip to the Money Museum in Colorado Springs, Colorado and learn about coin collecting and the new Lincoln penny. In 2009, the United States Mint will mint and issue four
different one-cent coins in recognition of the bicentennial ( 200
years) of President Abraham Lincoln's birth and the 100th anniversary
of the first issuance of the Lincoln cent. Produced by Nick Jr. as part of its virtual field trip series, Meet Me at the Corner. Extended lear

2.2 Jupiter's magnetic field and radiation zone
Jupiter has long been an object of wonder, with its dramatic Great Red Spot, its numerous and varied satellites and the stunning collision of the comet Shoemaker Levy 9 with the Jovian atmosphere in 1994. This unit will introduce you to our solar system's largest planet and its major satellites and the history of their exploration.
Empowering the young in an ageing society: Selene Biffi of Youth Action for Change
Influential decision makers are seldom youthful, but in Italy young adults could qualify as a marginalised minority group. Precarious and poorly-paid employment is endemic even for university graduates. Unemployment for those aged 15 to 24 is among the highest in Europe at nearly 20 per cent, and hovers roughly fourteen points higher than Italy’s general population.
Can CSR show us the money?
A Hayleys PLC case study addresses a gap in the literature on corporate social responsibility: namely, it is very hard to determine the true costs and benfits of CSR for a firm.

Taking Programming into Kindergartens: Exploratory Research Activities Using ToonTalk
We believe that computers should be introduced in kindergarten education under the same philosophy and methods employed for other elements of modern society. Children should be familiar with computers in general, not just with specific sets of skills. We see computer programming in particular as a way to empower children, allowing them to grasp fundamental computing concepts, and not fearing to use a computer in novel ways; they should be able to approach the computer-tool as an adaptable tool,
Determination of DNA Bases Chemistry: A Discovery-Based Experiment
The paper contains details of an electrochemistry lab where students are given the time to explore and design an experiment to identify the different DNA bases. The paper has a very useful compendium of literature relating to electrochemical techniques.
From Teaching to Learning: Part III. Lectures and Approaches to Active Learning
This is an article link from the Journal of Veterinary Medical Education applying active learning processes in veterinary classes focusing on asking questions and brainstorming in class. This page is for faculty, but is general and not specifically geared to analytical chemistry. The quality of content is excellent and uses examples of material used in a science lecture, Journal references are included.
