Das Thema soll in einen Grenzbereich der Materialwirtschaft führen, der durch die tagespolitischen Ereignisse immer größere Bedeutung für die Unternehmung gewinnt. Naturgemäß ist in einer marktorientierten Gesellschaft das verkaufs­ fähige Produkt da~ Objekt aller Anstrengungen und Leistungen. Produktion und Verkauf stehen im Blickpunkt, andere Bereiche werden als notwendig be­ trachtet, während das Gebiet der Entsorgung innerhalb der Unternehmung zu­ nächst ohne besondere Beachtung bleibt.

We say the iron is oxidized by the copper ions. As a result, iron ions (Fe+2) dissolve in the solution, and copper ions, having gained electrons, are deposited as copper atoms (Cu0) on the iron nail. The reaction is summarized by the equations below. ) Fe0 → Fe+2 + 2 electrons Cu+2 + 2 electrons → Cu0 The net reaction—the sum of the two reactions—is Fe0 + Cu+2 → Fe+2 + Cu0. Science Fair Project Idea Investigate the following questions and write a report: What is alchemy? Who were the alchemists?

It is the thing that changes, and it is the only difference between the two groups. During the experiment, you will collect data. For example, you might count the number of raisins that rise to the surface. You might time how long it takes for the raisins to rise. By comparing the data collected from the control group with the data collected from the experimental group, you will draw conclusions. Since the two groups were treated exactly alike, all the raisins in the ginger ale rising to the surface would allow you to conclude with confidence that it is a result of the one thing that was different: carbonation.

Can bleach make a dark, inky solution turn clear? Can it make a message written in normal visible ink disappear? Add a drop or two of black ink to some water in a glass and stir to mix. Under adult supervision, add a few drops of liquid bleach to the dark mixture. Stir for a minute or two, and the liquid will turn clear if you have added enough bleach. How many drops of bleach are required to clear up one drop of ink in water? Can the same bleach on a facial tissue be used to blot away a letter written with a felt-tip pen?
