How do societies assign value to land, labor, and material goods? Manorial economies in Japan and medieval Europe are contrasted with the tribute economy of the Inka, and the experience of dramatic economic change is illustrated by the commercial revolution in China. (28:35)
Fats to Fuel - Partners Video Magazine

End Sequence Profiling Computational Lab - Oliver Hampton
Computational laboratory: Starting from a set of breast cancer BACs (bacterial artificial chromosomes) End Sequence Profiling (ESP) is performed. ESP analysis sequences the ends of insert DNA in order to characterize genomic rearrangements that may be involved in breast cancer progression. In this study, genomic rearrangements are characterized from 100 breast cancer BACs and 10,000 Fosmids (derived from a pool of the 100 originating BAC) using ESP. Analysis and comparison of both BAC and Fosmid
Dissection - 02 - intrinsic muscles of the back
Dissection - 02- intrinsic muscles of the back - vertebral column - spinal meninges - spinal cord WARNING! Not for the faint hearted!!
Students construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.
Household Energy Conservation and Efficiency
Students complete three different activities to evaluate the energy consumption in a household and explore potential ways to reduce that consumption. The focus is on conservation and energy efficient electrical devices and appliances. The lesson reinforces the relationship between power and energy and associated measurements and calculations required to evaluate energy consumption. The lesson provides the students with more concrete information for completing their culminating unit assignment.
Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. Students learn the steps that engineers use to design bridges: understanding the problem, determining the potential bridge loads, calculating the highest possible load, and calculating the amount of material needed to resist the loads.
You're a Pushover!
The purpose of this activity is to demonstrate Newton's 3rd Law of Motion, which is the physical law that governs thrust in aircraft. The students will do several activities that show that for every action there is an equal and opposite reaction.
In this hands-on activity, students learn about two types of friction static and kinetic and the equation that governs them. They also measure the coefficient of static friction experimentally.
2.8 Network analysis
The power of graphics should not the underestimated. They can express information clearly and simply. This unit will help you to assess which style of graphic to use in different situations.
6.2 Pie charts: Activities
Your course might not include any maths or technical content but, at some point during your studies, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information, and possibly encouraged to present your own findings in this way. This unit will help you to develop the skills you need to do this, and gain the confidence to use them. This unit can be used in conjunction with, and builds on the ‘Working
Paleoecology as a Classroom Tool to Address Global Climate Change
A laboratory activity to illustrate paleoecological techniques by counting pollen on slides representing six different time periods from a site in Idaho. Based on the class data,the students will be asked to interpret how the vegetation has changed at the site as the climate change over time.
El Nino-La Nina Sea Surface Temp and Height Anomaly 3D Isometric View with Pan: January 1997 through
An animation of sea surface temperature and height anomalies in the Pacific for January 1997 through November 1998 from NOAA AVHRR and TOPEX Poseidon
Martin Van Buren's "Return to the Soil"
is a curriculum-oriented site using the home, named Lindenwald, the eighth President moved to after his term in office to introduce a discussion of Van Buren and his times. The site contains photos and drawings of Lindenwald as well as discussions how Van Buren interacted with other political leaders of the day, like Andrew Jackson and John C. Calhoun. The site offers many questions and suggestions for student assignments.
The M'Clintock House: A Home to the Women's Rights Movement
is a curriculum-oriented guide to a home in Waterloo, New York in which several early abolitionists, women's rights advocates, and social reformers lived. The site uses photos and drawings of the house as a beginning point to lead into readings about the First Woman's Rights Convention in nearby Seneca Falls in 1848.
Washington DC: A Guide to the Historic Neighborhoods and Monuments of Our Nation's Capital
presents 96 historic places that bring the 200-year history of our nation's capital to life. Learn not only about famous national landmarks -- the Mall, Capitol Building, White House -- but also about historic neighborhoods and local landmarks that make the city unique.
Space Week: Mars Underground, Part 2
The president of the Mars Society makes a passionate case for a manned planetary mission.
Science Digest - Episode 2 Animal Guy
Quirky Science Digest talk show host Mathew Arden interviews animal expert Brad Crane.

That students will identify key characters in the novel. That students will develop their understanding of the plot.
Modern proteomes contain putative imprints of ancient shifts in trace metal geochemistry
Because of the rise in atmospheric oxygen 2.3 billion years ago (Gya) and the subsequent changes in oceanic redox state over the last 2.3–1 Gya, trace metal bioavailability in marine environments has changed dramatically. Although theorized to have influenced the biological usage of metals leaving discernable genomic signals, a thorough and quantitative test of this hypothesis has been lacking. Using structural bioinformatics and whole-genome sequences, the Fe-, Zn-, Mn-, and Co-binding metall
