Mixed Reception Scenario
This activity is set in a research group that is developing an antivenom for spider bites. In the opening scene, Nelson Pogline, a talented graduate student, dies unexpectedly at a university reception. As a detective, you must use chemistry concepts to determine if this was murder and if so, solve the case. You can interview suspects using Quicktime movies, investigate the crime scene for clues with Quicktime Virtual Reality images, and analyze the evidence from the crime lab. This activity req
Essential Science for Teachers: Physical Science Session 3. Physical Changes and Conservation of Mat
What happens when sugar is dissolved in a glass of water or when a pot of water on the stove boils away? Do things ever really "disappear"? In everyday life, observations that things "disappear" or "appear" seem to contradict one of the fundamental laws of nature: matter can be neither created nor destroyed. In this session, participants learn how the principles of the particle model are consistent with conservation of matter.,The segment shows the interviewer trying to find out the student's id
Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer uses a model to represent what is happening when substances dissolve in water, as well as a representation of two different solutions. The interviewer then asks for a prediction of what would happen when two clear solutions are mixed together. The interviewer uses the model to help the student build an understanding of what happened to form the precipitate. The student also changed
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,This video segment is helpful in showing how th einterviewer uses the phenomenon of the Hawaiian Islands formation to probe for the student's ideas about volcanoes and how volcanoes form land masses such as the islands. She draws a picture to explain her idea and then draws a different picture. The interviewer uses this to probe further by asking her why she changed her mind. He also tries to get her to think abo
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment is helpful in showing teachers a useful technique to elicit students' ideas. The interviewer uses a refutation by stating a comment about what some scientists believe and asks the student to describe what she would say to them to refute their claim.
Guilford Courthouse National Military Park
describes weapons, medicine, food, leisure hours, and the role of women in the Revolutionary War. It also examines the battle that was the largest of the Southern Campaign and that helped change the course of the war.
This is a series of computer animations which demonstrate all the possible combinations of the ideal gas law or equation of state. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas. Careful, scientific observation has determined that these variables are related to one another and the values of these properties determine the state of the gas. In a scientific manner, we can fix any two of the fou
Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. They learn how Newton's second law of motion works by seeing directly that F = ma. When they pull the metal "arm" back further, thus applying a greater force to the cotton ball, it causes the cotton ball to travel faster and farther. Students also learn that objects of greater mass require more force to result in the same distance traveled by a lighter object.
Changing Military Doctrine
General Pierre-Marie Gallois, often regarded as the 'father' of the French nuclear strategy, served with the Supreme Headquarters Allied Powers Europe (SHAPE) and with French president Charles de Gaulle. In this video segment, Gallois provides a perspective that was shared by many Europeans, including General de Gaulle: that to replace the strategy of 'massive retaliation' with 'flexible response' meant a weakening of the United States' commitment to defend Europe with nuclear weapons. In his in
Human Security in an Age of Turbulence
Mary Kaldor is a prolific author who has written widely on a range of key issues over the years ranging from the 'Baroque Arsenal' (1982) a study that challenged the logic of militarism and the belief that more weapons meant more security, through to her groundbreaking 'New Wars'(1999) a book that reveals the new forms that organized violence will take in the 21st century. Mary Kaldor today is one of the most influential and respected alternative voices in the field of applied international poli
Can we eliminate nuclear weapons?
Twenty years after the fall of the Berlin Wall is the time finally right to achieve the elimination of nuclear weapons? Leading proponents of nuclear disarmament discuss why achieving Global Zero – a world without nuclear weapons – is both necessary and realistic.

Weapons of Mass Confusion: Assessing the True Risks
Panelists gathered for this discussion agree that when setting weapons policy it is counterproductive to lump weapons together. The dangers from nuclear, biological, and chemical weapons need to understood individually. Owen Cote says nuclear weapons, with their large-scale production process and instant lethal capacity, belong in one categ
Bomb Scare: The History and Future of Nuclear Weapons
Joseph Cirincione delivers an energetic and at times impassioned primer on the standoff with Iran on its nuclear program, drawn in part from his latest book, The History and Future of Nuclear Weapons (Columbia University Press, Spring 2007).
He offers a succinct ‘equation’ to describe what drives nat
Can Nuclear Energy and Non-Proliferation Co-Exist?
If nuclear energy becomes a central tool in addressing climate change, will nuclear weapons proliferation inevitably follow? In the words of Matthew Bunn, “The horse ain’t entirely out of the barn—there are still things to do.” He and fellow panelists acknowledge the link between civilian nuclear energy programs
Iran: War or Peace?
The Bush administration’s panic about failing in Iraq is now driving its fierce attitude toward Iran, according to Kenneth Pollack. President Bush’s 2007 State of the Union message hinted at exercising military force to deal with an Iran it accused of stoking up insurgency in Iraq. Pollack points out that historically
The Next Catastrophe: Reducing Our Vulnerabilities to Natural, Industrial, and Terrorist Disasters
It’s time to trade in the Department of Homeland Security for a Department of Homeland Vulnerabilities, says Charles Perrow. At its peril, our nation “privileges terrorism over natural and industrial disasters.”
From Perrow’s perspective, the U.S. landscape is riddled with “weapons of mass destruction:
An Evening with Video Artist Bill Viola
Bill Viola dims the lights in MIT’s Room 10-250, and begins to talk of life, death and all that lies between, leaving the realm of classroom and entering a place of potential enlightenment. Weaving together his video art, personal anecdotes, poetry and other writings from religious traditions spanning the globe and the ages, V
