Summary Fact-sheet describing the three different types of rock -- igneous, metamorphic and sedimentary.
Investigating Animal Respiration with Electronic Probes
This computer-assisted investigation allows students to explore the effect of variables on animal respiration using research-quality instrumentation. The model investigation is with a lizard (anole) exposed to a range of temperatures that are only moderately stressful and do no harm. The animal is contained in a transparent chamber with gas inlet and outlet ports and an electronic thermometer. Carbon dioxide-free air is pumped at a constant rate into the chamber. The outgoing air enriched in car

1907: Gift to New York University
This image is a document outlining the details of a gift of real estate from Margaret Olivia Slocum Sage to New York University. This gift is intended to be used to create a college for women to be named Olivia Sage College. Neither of these conditions was carried out.,In October 1906, Olivia Sage had donated the huge sum of $294,250 to New York University, on condition that "some part of the property at least will be used by New York University as a center for for women's working and living, fo
"In the Shadow of Society": Migrant Workers and Unionists Urge Congress to Enact Effective Federal F
In the early 20th century, large-scale commercial agriculture displaced family farms, tenant farmers, and sharecroppers. Hand labor, however, remained more cost effective for harvesting certain fruits and vegetables. Farmworkers under this new system were hired only for seasonal work and had to travel frequently. The migratory experience left these workers--primarily Mexicans, Mexican Americans, African Americans, Puerto Ricans, and Filipinos÷permanent outsiders and vulnerable to exploitation,
Terrorism, Peace, and Other Inconsistencies
This course addresses a set of inter-related questions that have become central to peace and security in the modern era, at both the domestic and international levels. What is the history and rationale for contemporary terrorism, including suicide terrorism? What does the rise of al-Qaeda terror mean for a host of problematic issues including the relationship between the Western and Islamic worlds, the future of peace in the Middle East, the future of various western foreign policy actions? What

Slide Right on By Using an Inclined Plane
Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device. During a hands-on activity, students see how the angle of inclination and pull force can make it easier (or harder) to pull an object up an inclined plane.
Sleeping Beauty Invades Rat's Genome
Knockouts are not just for Mice anymore. Aron Geurts and Howard Jacob from the Medical College of Wisconsin talk about their plans for creating transgenic rats using the Sleeping beauty transposon. Coming out of work pioneered by Colin Bishop's lab, Geurts and Jacob describe how the Sleeping Beauty system can be used to make transgenic rats and their plans to make the phenotype data from these rats available via the MCW PGA website (http://pga.mcw.edu) and the strains themselves accessible via a
Phase Relations in Reservoir engineering
In this course you will learn about phase relations as applied to oil and/or gas reservoir processes, enhanced oil recovery, gas pipeline transportation, natural gas processing and liquefaction, and other problems in petroleum production. The primary objective of the course is to apply the thermodynamics of phase equilibrium to the framework for phase behavior modeling of petroleum fluids. The focus of the course will be on equilibrium thermodynamics and its relevance to phase behavior predictio
2.7 Multiple-cause diagrams
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.
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of
Tissue movement in bipopulation tumour cord growth
Simulation of tumor cord growth where conversion of the tumor to glycolytic (anaerobic) metabolism takes place under hypoxia. This video shows volume fraction of glycolytic cell population and velocity of tissue movement. Isolines show hypoxia limits for aerobic and anaerobic cell lines respectively. This video reflects work in progress and may be different from the final results.
Economic History & History of Thought
The factories that changed the world, 1.) the mule-powered spinning mill (Britain in the 1820s), 2.) from the American system to the Ford system (1900s), and 3.) Toyota Production System (Lean manufacturing), are contrasted and the progression of production systems of the 19th and 20th centuries are arranged in order.
