Chiton from the California rocky intertidal zone
Chitons have oval shaped, eight segment hard shells that provide protection for their soft shelled bodies. The plates of the shell allow for more flexible movement of the animal. The entire soft body is covered by the shell.

Food Fight: A Teach-in On the 2007 Farm Bill
Michael Pollan moderates a panel discussion of the 2007 farm bill, now being debated, with guests Dan Imhoff, the author of Food Fight: A Citizen's Guide to the Farm Bill; George Naylor, Iowa corn farmer and president of the National Family Farms Coalition; Ann Cooper, Director of Nutrition Services for the Berkeley school system, and other leaders in the effort to reform federal agricultural policies.
Every five years or so, the President signs an obscure piece of legislation that determines w
Assessing Japan's April 7 Aftershock
Dr. Bernard Weinstein, an economist at SMU, talks with The Weather Channel about the effect of an aftershock in Japan on April 7 on the world economy.
Introduction to the Old Testament (Hebrew Bible)
This course examines the Old Testament (Hebrew Bible) as an expression of the religious life and thought of ancient Israel, and a foundational document of Western civilization. A wide range of methodologies, including source criticism and the historical-critical school, tradition criticism, redaction criticism, and literary and canonical approaches are applied to the study and interpretation of the Bible. Special emphasis is placed on the Bible against the backdrop of its historical and cultural
Oscillator Chain Model
The EJS Oscillator Chain model shows a one-dimensional linear array of coupled harmonic oscillators with fixed ends. This model can be used to study the propagation of waves in a continuous medium and the vibrational modes of a crystalline lattice. The EJS model shown here contains 31 coupled oscillators equally spaced within the interval [0, 2 pi] with fixed ends.
Tardigrade Species Distribution Project: Lesson Plan
This online lesson plan was designed for students taking part in the active research project to document the distribution of a new species of tardigrade, a microscopic invertebrate animal. The project is part of a nationwide online collaborative research project. The lesson plan offers instructional procedures for teachers and lists materials and procedures for collecting, observing, and culturing tardigrades. The lesson involves collecting samples in the field, examining and classifying tartigr
Seasonal Migrations: Whooping Cranes
Children follow the migrations of animals. They observe, research, and report their findings, and watch journeys progress on real-time maps. Through these interrelated investigations, students discover that sunlight drives all living systems and they learn about the dynamic ecosystem that surrounds and connects them. Fall: Students watch chicks grow and then "join" the migration as humans teach the birds a new route using an ultra-light plane to lead the way. Daily updates: September-December.

Occupational Sex Segregation
Occupational sex segregation will be studied by focusing on traditionally gender-oriented occupations and analyzing which have an increasing proportion of males or females, and which are still mainly gender-specific jobs. These analyses will be done by age group to study trends at different stages of people's careers.
"Add 'Em Up"- A Song About Basic Addition
This computer-animated song shows students how to add one to one-digit numbers. The video strives to provide a conceptual understanding of the concept by showing each problem with cubes and numbers. Students can use cubes to demonstrate the problems as the video plays. ( 3:18)
Maximum Ozone Hole Area for 2000
This still shows the maximum stratospheric ozone hole over the Antarctic for 2000.
Life in the City
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a close-up look at biodiversity in a city park. The site opens by telling kids that, despite appearances, a great deal of biodiversity exists in cities. That from tiny mites to mighty trees, thousands of species thrive there. It then takes them to a slice of life from a thriving city park, where they are asked to find 10 hidden critters living alongside the trees, plant
Small Regulatory RNAs May Sharpen Spatial Expression Patterns
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis, others ar

"Literary Interpretation: Literature and Urban Experience, Spring 2009"
" Alienation, overcrowding, sensory overload, homelessness, criminality, violence, loneliness, sprawl, blight. How have the realities of city living influenced literature's formal and thematic techniques? How useful is it to think of literature as its own kind of "map" of urban space? Are cities too grand, heterogeneous, and shifting to be captured by writers? In this seminar we will seek answers to these questions in key city literature, and in theoretical works that endeavor to understand the
No Valve in Vain
In this activity, students will design and create their own heart valves out of a variety of materials given to them, including: waterproof tape, plastic tubing, flexible plastic sheets, foam sheets, scissors, clay, etc. This activity will not only test their understanding of how a one-way valve works and its purpose, but will also allow them a chance to think outside of the box and practice engineering problem-solving.
