Input: In her storage room-turned-office, Jennifer Baum works under an expanding leak that is causing the ceiling to turn brown and crumble. Mold grows in the buckets positioned to catch the water. She shrugs it off. Outside her office she has taped up a clear plastic suit, and a sign that reads, "All employees must don protective gear before coming in." Such is life in limbo. Nearly a year after Sept. 11, the Legal Aid Society-the lawyers for New York's poor and homeless-remains, well, homeless. The nonprofit has been barred from returning to its 90 Church St. headquarters, across from the World Trade Center site, because of environmental concerns. Legal Aid has uncomfortable company. More than 11,500 New Yorkers continue to work out of temporary space, according to analysis by Manhattan-based real estate brokerage TenantWise.com Inc. and Crain's New York Business. That's 8% of the 137,000 workers who lost their offices or access to them when the Twin Towers collapsed. Legal Aid's 450 displaced attorneys and staffers have spent the past 12 months spread among previously unused spaces-some unused for good reason-in the nonprofit's other offices. It could be another year and a half before they return to their old desks. They have contended with difficult working conditions as demand for Legal Aid's services is on the rise because of Sept. 11 and the deteriorating economy. The civil division is spread among a few boroughs. Their papers and documents, some 20,000 boxes worth, are stuck in a storage facility in Linden, N.J. "I am counting the days till we can have all the parts back in one place," says Steven Banks, Legal Aid's associate attorney in chief. In the memories of the exiled workers, the old office has achieved mythical proportions. They say the wood paneling and rugs had the ability to cool emotions and lift spirits. The Legal Aid office on Montague Street in Brooklyn Heights, where 65 displaced workers have cobbled together space amid the faded and scratched walls, looks more like a bargain basement.

Input: If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

Input: The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. Knowing it acts like a magnet is one thing. Knowing why it acts like a magnet is more difficult. In fact, finding out why is a fairly recent discovery. To find out why required new technology. It was the seismograph that made it possible to learn why the Earth acted like a magnet. Seismograph are used to study earthquakes. By studying earthquake waves they were able to learn about Earths interior. They discovered that Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated here. It is caused by the motion of this liquid metal. The liquid metal moves as Earth spins on its axis.
"How does the liquid metal within the Earth's core generate a magnetic field?" is "It is caused by the motion of this liquid metal"?
