Science collection (New York, N.Y.) Standard deviants core curriculum Ultimate media librarian collection Welcome to the nanoworld!Summary: Iron ore is reduced and manufactured into steel in a modern plant where, in a continuous process, ore is crushed and mixed with coke and then fed into the top of a blast furnace. Molten iron flows off from the bottom; slag is skimmed off; and iron is converted to steel by blowing oxygen through it to remove residual carbon, adding lime and magnesium powder to remove other trace solid...

Summary: Limestone, or calcium carbonate-made of the skeletons of billions of sea creatures-is mined in large quantities. Carefully blasted out of the ground, it is first crushed with huge pestles to eliminate large boulders, then passed through a series of sieves to separate large chunks for further crushing. When sufficiently small, it is washed to remove clay, dust, and sand. The grades are...

Summary: Until the 17th century, the building blocks of the natural world were a mystery. Of elements there were believed to be four - air, earth, fire, and water - and the science of chemistry had yet to be born. This program identifies some of the first chemical elements to be discovered by spotlighting the work of Hennig Brandt, Robert Boyle, Henry Cavendish, Joseph Priestly, Antoine Lavoisier, and...

Summary: At the beginning of the 19th century, 55 elements had been discovered, and although scientists had no idea how many more they might yet find, they already had a suspicion that there was some sort of unifying pattern behind them all. This program charts the quest for order among the chemical elements by examining the contributions of Dmitri Mendeleev, creator of the Periodic Table of Elements,...

Summary: Everything is made up of atoms, but what are atoms made of? This program summarizes modern atomic theory and the chemistry of atoms. First, modern atomic theory is explained with emphasis on some of the major breakthroughs by Ernest Rutherford, who experimented with alpha particles; Niels Bohr, who observed the valency of elements; and Dmitri Mendeleev, who designed the periodic table of...

Summary: Aluminum is extracted and purified from clays and rocks at a British plant by purifying bauxite ore to aluminum oxide and reducing this oxide to molten metal. The influence of economic factors is seen in the location of aluminum plants, which consume large amounts of electrical energy. In the United States, plants are located close to the power source rather than to ore deposits; in England,...

Summary: A second product made from sodium chloride, sodium metal, is also produced at the chemical plant shown in Chemicals from NaCl: 1. It is formed by electrolysis of a sodium chloride, calcium chloride molten mixture, and is isolated at the cathode of the cell as a liquid. This product is extremely reactive; it must be handled very carefully and packaged in an inert oil, free from air and moisture....

Summary: In part one of this program, chemistry authorities, including "Helium Man" and two janitors, lay down the law-Boyle's Law, Graham's Law, and Dalton's Law. They also present the Kinetic Molecular Theory and the Ideal Gas Equation and elaborate on partial pressures and the difference between diffusion and effusion. Part two investigates kinetic energy; ion-dipole, dipole-dipole, and London...
