Tools and Equipment, Part I
Through a series of activities, students discover that the concept of mechanical advantage describes reality fairly well. They act as engineers creating a design for a ramp at a construction site by measuring four different inclined planes and calculating the ideal mechanical advantage versus the actual mechanical advantage of each. Then, they use their analysis to make recommendations for the construction site.
Students are introduced to the circulatory system, the heart, and blood flow in the human body. Through guided pre-reading, during-reading and post-reading activities, students learn about the circulatory system's parts, functions and disorders, as well as engineering medical solutions. By cultivating literacy practices as presented in this lesson, students can improve their scientific and technological literacy.
Carbon nanotube reinforced carbon nano composite fibrils by electro-spinning
Fibers of Polyacrylonitrile (PAN) are the precursor of 90% of produced carbon fibers. It is generally thought that the better the degree of molecular orientation in the original PAN fiber, the better the mechanical properties, in particular the modulus of the resultant fibers. Electro-spinning is a unique process in that it is able to produce polymer fibers having diameters ranging over seve ral orders of magnitude, from the micrometer range typical of conventional fibers down to the nanometer r

Energy Metabolism from the course Introduction to Human Nutrition
Introduction to Human Nutrition - Fall 2006.This course provides an overview of digestion and metabolism of nutrients. Foods are discussed as a source of nutrients, and the evidence is reviewed as to the effects of nutrition on health. The emphasis of the course is on issues of current interest and on worldwide problems of food and nutrition. Students are required to record their own diet, calculate its composition, and evaluate its nutrient content in light of their particular needs.
This case study describes the current trend for crime scene investigation drama and news stories of personal tragedies involving incorrect or missing data have been harnessed to capture the attention and inspire learning and enterprise skills in students studying database compilation

Multiplication Rule (Probability "and")
The instructor, while using computer software, discusses the multiplication rule in probability. The instructor talks a little fast, so this video will be more helpful if a classroom teacher supplements this information with prior discussion. (03:24)
Rembrandt and the Face of Jesus
August 3, 2011 - October 30, 2011: This exhibition reunites, for the first time since 1656, seven paintings of Jesus by Dutch master Rembrandt van Rijn. Abandoning traditional sources, Rembrandt created these exceedingly rare portraits of Christ with the use of a human model--a step which was totally unprecedented at the time. In viewing them today, visitors are presented with a number of religious, historic, and artistic questions to ponder.

"Advanced Semantics, Spring 2009"
" In the wake of Katrina the entire gulf coast is embroiled in a struggle over what constitutes "appropriate" rebuilding and redevelopment efforts. This practicum will engage students in a set of work groups designed to assist local community based institutions and people in shaping the policy and practices that will guide the redevelopment and rebuilding efforts in the city of New Orleans."
