Stellar Wind Disruption by an Orbiting Neutron Star: Low X-Ray Luminosity
A tiny neutron star orbits incessantly around a massive star with a diameter a million times larger than its own. The high luminosity of the massive star drives a strong wind from its surface. The neutron star crashes through this wind at over 300 kilometers per second. The gravity and X-ray luminosity of the neutron star act to disrupt the wind, producing an extended wake of dense gas trailing behind the neutron star. This simulation, in the reference frame of the neutron star, shows conditions

"Introduction to Neuroscience, Fall 2007"
" This course is an introduction to the mammalian nervous system, with emphasis on the structure and function of the human brain. Topics include the function of nerve cells, sensory systems, control of movement, learning and memory, and diseases of the brain."
Aerodynamics: applications of force and flow
Although there is a great deal of historical information about aerodynamics that could be discussed here, we purposely narrowed the stream of resources to those that encourage students to experiment with technological design and function.
Math Literature Connections: Patterns and Algebra
Ideas and activities that use Two of Everything, One Grain of Rice and the King's Chessboard to introduce students to function machines and input/output tables. Links to appropriate templates are also provided.
Personal Preparedness Planning For Public Health Workers
Public health workers need to understand and implement basic concepts of personal preparedness planning so that they can function effectively as public health emergency responders in a post-9/11 world. These basic preparedness strategies can be applied to meet a broad range of public health emergency response challenges, including - but not limited to - acts of terrorism. Personal Preparedness Planning provides a practical introduction to these concepts that is tailored to the needs of public he
The Cardiovascular System

This patient education program explains certain arthritic conditions, including osteoarthritis and rheumatoid arthritis, and their treatment options. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.
Kidney Stones (Spanish)
This patient education program discusses kidney stones including how they are formed, their symptoms, diagnosis, treatment options, and prevention. It also reviews the anatomy and function of the kidneys. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, ...
Soil: The Great Decomposer
The purpose of this resource is to understand that soil, under different environmental conditions, plays a role in the decomposition of organic materials. Students use bottle experiments to observe changes in the decomposition of vegetable scraps. Students vary temperature, moisture, and light conditions to determine the conditions that best facilitate the decomposition of organic material in soil.
Water Vapor Protocol
The purpose of this activity is to measure the total precipitable water vapor (column water vapor) in the atmosphere above an observer's site. Students point a GLOBE/GIFTS water vapor instrument at the sun and record the voltage readings from a digital voltmeter. They observe sky conditions near the Sun and perform the Cloud Protocols. Intended outcomes are that students understand the concept that the atmosphere prevents some of the sun's light from reaching Earth's surface, how water vapor mea
The purpose of this activity is to measure the aerosol optical thickness of the atmosphere (how much of the sun's light is scattered or absorbed by particles suspended in the air). Students point a GLOBE sun photometer at the sun and record the largest voltage reading they obtain on a digital voltmeter connected to the photometer. Students observe sky conditions near the sun, perform the Cloud, Optional Barometric Pressure (optional) and Relative Humidity Protocols, and measure current air tempe
Space Weather Research Explorer
looks at how the sun creates a changing set of conditions in space. Learn about coronal holes, solar flares, coronal mass ejections, solar wind, magnetosphere, and auroras. See photos, graphs, and live data. Make your own space weather predictions.
Microscope Imaging Station
This site shows what blood is, what happens when the immune system goes awry, what are stem cells are, and more. See videos exploring cell structure and function, cell development and motility, plankton, plants, and protozoa. Learn how the sea urchin helps us understand genes, reproduction, and cancer.
Momodou Ceesay talks about the function of an artist
Gambian artist Momodou Ceesay, painting instructor at the Elma Lewis School of Fine Arts and at Roxbury Community College, talks about his function as an artist and his recent work illustrating African stories for children.
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.

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
