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: Because of its wide availability, NaCl is the starting material for many inorganic chemicals. In this program, salt is seen being pumped to the surface from deposits of 1011 tons in salt fields as a brine solution, and into a chemical plant where chlorine and sodium hydroxide are produced by electrolysis. Three types of cells used to separate the products at the anode and cathode-mercury...

Summary: Earth, air, fire, and water: according to some ancient theories, these four elements made up the cosmos. Beginning with the work of the Greek philosopher Democritus, this Science Screen Report describes how an accurate atomic theory developed and led to awareness of a wide variety of elements. Specific examples showing different configurations of these basic units of matter-including graphite...

Summary: This program traces the water cycle, beginning with the collection of rainwater in rivers and lakes, in great detail through a water treatment plant, to some of the places where water is used, and finally back into the atmosphere. Treatment of the water begins with the use of chlorine to destroy organisms; the water is then filtered through various sedimentation tanks to remove solid matter....
