The Path of Electrons
Students engage in an interactive "hot potato" demonstration to gain an appreciation for the flow of electrons through a circuit. Students role play the different parts of a simple circuit and send small items representing electrons (paper or candy pieces) through the circuit.
What's a Kid to Do?
Students write letters as part of an environmental action campaign. They become more aware of global environmental problems and play a part in their solution.
What's Down There?
During this activity, students will learn how oil is formed and where in the Earth we find it. Students will take a core sample to look for oil in a model of the Earth. They will analyze their sample and make an informed decision as to whether or not they should "drill for oil" in a specific location.
Warwick students to power space satellite
Bill Crofts and student, Kennith Leong, talk about the project they are involved in to design and build power supply systems for a moon orbiting satellite planned for launch by the European Space Agency (ESA) in 2011.

2.500 Desalination and Water Purification (MIT)
Water supply is a problem of worldwide concern: more than 1 billion people do not have reliable access to clean drinking water. Water is a particular problem for the developing world, but scarcity also impacts industrial societies. Water purification and desalination technology can be used to convert brackish ground water or seawater into drinking water. The challenge is to do so sustainably, with minimum cost and energy consumption, and with appropriately accessible technologies.

6.172 Performance Engineering of Software Systems (MIT)
Modern computing platforms provide unprecedented amounts of raw computational power. But significant complexity comes along with this power, to the point that making useful computations exploit even a fraction of the potential of the computing platform is a substantial challenge. Indeed, obtaining good performance requires a comprehensive understanding of all layers of the underlying platform, deep insight into the computation at hand, and the ingenuity and creativity required to obtain an effec
14.15J Networks (MIT)
Networks are ubiquitous in our modern society. The World Wide Web that links us to and enables information flows with the rest of the world is the most visible example. It is, however, only one of many networks within which we are situated. Our social life is organized around networks of friends and colleagues. These networks determine our information, influence our opinions, and shape our political attitudes. They also link us, often through important but weak ties, to everybody else in the Uni
HST.725 Music Perception and Cognition (MIT)
This course is a survey of perceptual and cognitive aspects of the psychology of music, with special emphasis on underlying neuronal and neurocomputational representations and mechanisms. Basic perceptual dimensions of hearing (pitch, timbre, consonance/roughness, loudness, auditory grouping) form salient qualities, contrasts, patterns and streams that are used in music to convey melody, harmony, rhythm and separate voices. Perceptual, cognitive, and neurophysiological aspects of the temporal di
American-Sino Relations: Review
In the third and final part of this series, Rosemary Foot reviews and critiques the four factors outlined in the previous episode which could hinder good relations between the two nations
