Vestibule (In 3 Episodes)
Episode 1: 'Place' -The color image of an apartment building vestibule shot from across the street is accompanied by a sound track of street sounds and narrated text adapted from The Moviegoer by Walker Percy. Excerpts of the text are displayed in the lower third of the screen. The image of the vestibule is interrupted by a girl riding a bicycle, a child riding a scooter, a man carrying a glass vase, and a man driving a red Pontiac. Each of these actions occurs in slow motion from right to left
Heisenberg Uncertainty Principle, The: A Video Opera
'The Heisenberg Uncertainty Principle' is divided into several distinct sections, the contents of which are described as follow: Act 1: The Gloria: Nature scenes accompanied by opera punctuated by flashes of city scenes, followed by shots of city landscapes; Interlude 1: Computer graphic shots of sexless bodies; Act 2: Pursuit for Plastic: Children play among ruins, accompanied by a score of children singing; two boys push and shove before one of the boys runs off into a field; Interlude 2: Comp
Anges Rebelles, Les
"In six minutes, a conjuring trick combining special effects and the magic of painting enables us to enter the world of Jacques Brissot. It is a visual poem that humorously recounts the building of a collage inspired from artist Peter Breugel's 'La Chute des Anges Rebelles.'" Artist Jacques Brissot is shown adding to and retouching a large-scale collage work, lending insight into his compositional choices and his techniques and methods. Music is by Michel Arich, with Barney Wilen playing saxopho
'Split Britches' is the story of three women from the Blue Ridge Mountains of Virginia, set sometime in the 1930's, whose squabbling is often pacified by periods of singing.
Coffee Coloured Children
'Coffee Coloured Children' is a powerful exploration of the impact of cultural pressure on self-image. Based on the daily experience of mixed-race children, the narrator recalls the pain and confusion of her own childhood spent in an all-white neighborhood with a white mother and an absent black father. The work opens with a video essay showing adults and children of many ethnicities interacting harmoniously to an upbeat and soulful song with a chorus about 'coffee-colored people.' Through narra
At the opening of 'Freefall,' Gaby Agis is seen getting dressed in Western-influenced clothing. She runs through alleyways and streets. Meanwhile, on neighboring rooftops, women are dancing together across vast spaces. Agis eventually makes her way to one of these rooftops. In the second section, Agis and another woman are partnering together against a wall of aluminum siding. They bounce off one another and the wall. Following this, Agis makes her way into an area filled with lush vegetation. H
'Two solo performances by two choreographers. Against an incessant beat and a glowing red backdrop, Susan Rose's energetic dancing is captured by dramatic camera angles. Through a series of landscapes, Louise Burns' delicate balletic movements float across the screen.' Susan Rose remains seated throughout her solo, performing intensely focused gestures with her arms and legs. Louise Burns takes to the out-of-doors, executing her precise movements at the beach, along a ridge trail, and overlookin
Every Picture Tells a Story: K-4
These activities are designed to create a sense of disequilibrium in the visual perception of students to make them aware of different ways to to view a picture. The students will view the images, decide what they see in each, record their ideas, and write a story based upon these findings.
StarChild: A Learning Center for Young Astronomers
The information and activities found in StarChild can be used to engage, excite, and educate students in your classrooms. Helps elementary school students learn about the sun and moon, planets, the asteroid belt, meteoroids and comets, astronauts and space suits, space travel and space probes, the Hubble space telescope, the Columbia accident, galaxies, the Milky Way, stars, quasars, black holes, cosmology, and dark matter.
Earth's Magnetic Field
The POETRY website explores solar storms and how they affect us, space weather, and the Northern Lights. A 64-page workbook of hands-on activities examines Earth's magnetosphere. Create a classroom magnetometer. Solve the space science problem of the week.
Solar Physics: The Sun Spot Cycle
This NASA website contains extensive information on sun spots and sun spot prediction. Users have access to several forms of graphical and numerical data such as sun spot numbers, the Maunder minimum, the Butterfly diagram, the Greenwich sunspot data and sun spot cycle predictions. The site also includes a wealth of information about the sun and NASA's ongoing sun research.

Symmetries and Their Properties-Part 4: Glide Reflections
A glide reflection is a symmetry transformation that consists of a translation followed by a reflection across the translation line. Of all the different symmetries, this is the hardest for students to understand and to identify. Glide reflections are very tricky to identify in a tiling or wallpaper pattern. The “footprints” image helps, but you can still expect students to have trouble. Using tracing paper over a design may also help.
Sticks and Stones Game
Students will play Sticks and Stones, a game based on the Apache game "Throw Sticks," which was played at multi-nation celebrations. Students will collect data, investigate the likelihood of various moves, and use basic ideas of expected value to determine the average number of turns needed to win a game.
X-Ray Vision, Crystallography
This site features a tutorial designed to allow students to gain an appreciation of how X-ray crystallography works. Using X-ray diffraction patterns to determine the arrangement of atoms in a molecule requires sophisticated mathematics. This activity depends only on light from an overhead projector passing through a ball-and-stick molecular model placed on the stage of the projector, making it an ideal introduction to x-ray diffraction.
Twinning, Polymorphism, Polytypism, Pseudomorphism
This site is a lecture by Dr. Stephen Nelson from Tulane University that discusses the various nonstandard forms of crystal growth that are characteristic to some minerals. Topics include twinning (contact and penetration, polysynthetic and cyclical), the origins of twinning, and twin laws in the triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, and isometric systems. Various types of polymorphism in many minerals are discussed as well as polytypism, metamict minerals, mineraloids, and
The Atmosphere And Its Relation To The Crust And Hydrosphere
This site provides an illustrated lecture from a geochemistry course offered by Dr. Scott Wood at the University of Idaho. Topics include a review of the structure and formation of the Earth's crust, atmosphere, and hydrological cycle, and the composition of the atmosphere. Additional topics covered are the concept of residence time, geological and biological sources of components in the atmosphere, acid-base theory, Henry's law and the solubility of gases in water, primary and secondary air pol
Origin Of The Universe And The Abundance Of Elements
This resource features an illustrated lecture from a geochemistry course offered by Dr. Scott Wood at the University of Idaho. Topics include the Big Bang theory, the evolution of stars, the relative abundances of elements in the Universe, and some fundamental nucleosynthetic processes that explain elemental abundance patterns. The lecture presentation may be downloaded as a PDF document or a PowerPoint presentation. Reading assignments and a homework problem set with answers is also provided.
Axial Ratios, Parameters, Miller Indices
This site is a lecture about crystal structure from Dr. Stephen Nelson at Tulane University. Topics include axial ratios, intercepts of crystal faces (Weiss Parameters), determination of the Miller Index of a crystal, the modified notation of hexagonal systems, which is referred to as Miller-Bravais Indices, and using the Miller Index notation to designate crystal forms. Tables and illustrations accompany the text.
