The Changing Geographic Distribution of Malaria with Global Climate Warming
In this exercise, students analyze climate data to find areas in the southern United States that are now close to having conditions in which the malaria parasite and its mosquito hosts thrive. Then they attempt to forecast when areas might become climatically suitable. Learning goals, context for use, ...
Biomechatronics is a contraction of biomechanics and mechatronics. In this course the function and coordination of the human motion apparatus is the central focus, and the design of assistive devices for the support of the function of the motion apparatus.
Stochastic Evolution Equati
The lectures are at a beginning graduate level and assume only basic familiarity with Functional Analysis and Probability Theory. Topics covered include: Random variables in Banach spaces: Gaussian random variables, contraction principles, Kahane-Khintchine inequality, Anderson’s inequality. Stochastic ...
Highlight the meaning of a function, and see how it can be seen as something changing over time, with this tool that links a motion model to a graph.
Mating preference in the commercially imported bumblebee species Bombus terrestris in Britain (Hymen
Commercial trade of bumblebees in Europe results in different subspecies of Bombus terrestris being shipped into regions where they are not native. Although previous studies have shown that these subspecies will interbreed, none have assessed mating preference of the different populations. This study examines the mating preferences between two geographically isolated populations of B. terrestris which have unnaturally been brought together through the commercial trade in bumblebees. Under contr
The Effects of Cattle Grazing on Vegetation in a Shortgrass Prairie Ecosystem
Grazing by large herbivores has profound effects on both the structure and function of shortgrass prairie ecosystems. In this exercise a grazed section of prairie on a working cattle ranch is compared to a less grazed section on an adjacent wildlife refuge. The Daubenmire canopy-coverage method is used ...
Using Bromelain in Pineapple Juice to Investigate Enzyme Function
This investigation introduces students to the structure and function of the proteolytic enzyme, bromelain, which is present in large quantities in the fruit, leaves, and stems of pineapple. In this lab exercise, students study the rate at which bromelain catalyzes the hydrolysis of gelatin (substrate) at different temperatures and pHs. Strips of developed black and white photographic film are placed in freshly squeezed pineapple juice under different experimental conditions. The time it takes fo
Thinking Systematically -- Grade 6 (Japan)
"Thinking Systematically" teaches students to find the value of two quantities that satisfy two conditions. Students are asked to determine the number of pencils and ballpoint pens bought if the total number of items purchased was 10 and the total price was 460 yen.
Inequality in America.
While many Americans are working harder for less money and paying more for everyday items like gas and food, the rich are getting richer. Bill Moyers Journal analyzes the growing inequality gap on the ground in los Angeles where recently union workers marched to bring attention to how they are getting squeezed out of the shrinking middle class. Bill Moyers also interviews Steve Fraser, historian and author of Wall Street: America's Dream Palace, about the modern parallels and differences to th
International Classification of Function, Disability and Health
This package was originally designed for undergraduates in Medicine at the University of Nottingham. It will also be useful to students in nursing, allied health professions and pharmacy. Practitioners in these fields, who are new to the ICF, will also find it a useful introduction. It describes the International Classification of Functioning, Disability and Health (ICF), a classification system published by the World Health Organisation to describe health status. This system is widely used in
Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences. The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a unifo
032 The Philippe de Montebello Years: Mangaaka Power Figure
Alisa LaGamma and Philippe de Montebello discuss the original form and function of this arresting sculpture from Central Africa. Recorded on the occasion of "The Philippe de Montebello Years: Curators Celebrate Three Decades of Acquisitions", on view from October 24, 2008–February 1, 2009.

Photographs of Lewis Hine: Documentation of Child Labor
This lesson encourages students to analyze dozens of photographs taken in the early 1900s depicting working conditions for child laborers. This lesson correlates to the National History Standards and the National Standards for Civics and Social Sciences. It has cross-curricular connections with history, government, language arts, and business law.
Ocean Surface Topography From Space: El Nino/La Nina and the Pacific Decadal Oscillation
Materials presented here are intended to help the learner understand the complex interactions between the oceans and the atmosphere that affect global weather and climate events. Users may learn how data from the TOPEX/Poseidon and Jason-1 satellites provide monitoring of oceanic conditions that may produce El-Nino/La Nina events, and help track the Pacific Decadal Oscillation (PDO), a long-term oceanic fluctuation. A selection of links to related sites is included.
"From Molecules to Behavior: Synaptic Neurophysiology, Spring 2010"
"Like transistors in a computer, synapses perform complex computations and connect the brain's non-linear processing elements (neurons) into a functional circuit. Understanding the role of synapses in neuronal computation is essential to understanding how the brain works. In this course students will be introduced to cutting-edge research in the field of synaptic neurophysiology. The course will cover such topics as synapse formation, synaptic function, synaptic plasticity, the roles of synapses
Lugosi teaches math - convergence of series 2
In part 2 of Béla Lugosi's lecture on convergence of series, he continues to discuss integration of the limit function in these series or sequences. He then goes further into applying these into power series. This is a video for advanced math students who are well into Calculus and Calculus II.
Florence Nightingale Biography, Part I
This is an animated biography from the Discovery Channel Education series. This series is aimed at older elementary school children. Florence Nightingale was a "pioneering English nurse, writer and noted statistician. Florence Nightingale's most famous contribution came during the Crimean War, which became her central focus when reports began to filter back to Britain about the horrific conditions for the wounded"(Wikipedia, 2009).
