Facism essays

Facism essays 3. Publisher: Raintree Steck-Vaughn Publishers 6. How long did it take to read the book? 1 day 7. Why did you choose this book? I wanted to get a better understanding of fascism. 8. What is the main subject of the book? The nature of fascism and the studies of two fascist states, Italy and Germany. 9. Benito Mussolini was dictator of Italy from 1922-1943. As a little boy, he was proved bright but violent. He was expelled from school fives times. Out of these five times, two were for stabbing fellow students. Mussolini had different careers before he reached the age of 30. He was a teacher, laborer, agitator, army deserter, journalist, union organizer, prisoner, and editor of the Socialist Party newspaper Avanti! He was drafted in 1915 and served as corporal until he was wounded and was discharged in 1917. Gabriele dAnnunzio was a famous poet at the age of 16. While fighting in World War I, Gabriele lost an eye and was given the award of bravery. A daring air raid over Vienna in 1918 made him a national hero. Gabriele was admired by many for acting boldly in a bombardment between the disputing sides of Italy and Yugoslavia. He later became a strong support of fascism but preferred to write rather then deal with politics. Adolf Hitler was born in Austria in 1889. He was not born a German. Adolf was a failure in school. He moved to Vienna and then to Munich to pursue other interests. Though he lacked education, money, family, and friends, he still dreamed of greatness within himself. He volunteered to be in the war when it just broke out in 1914. Hitler won the Iron Cross twice but was never promoted to a higher position other then corporal. 10. The book first describes how fascism came to be. It was after World War I when the fascist movements managed to turn Italy and Germany, two ...

Gold and Silver Pennies Chemistry Project

Gold and Silver Pennies Chemistry Project All you need are a couple of common chemicals to turn your normal copper-colored pennies (or another mainly-copper object) from copper to silver and then to gold. No, the coins wont really be silver or gold. The actual metal involved is zinc. This project is easy to do. While I dont recommend it for very young kids, Id consider it appropriate for kids ages third grade and older, with adult supervision. Materials Needed for this Project clean pennies zinc metal (preferably powder) sodium hydroxide or sodium hydroxide solutiontweezers or tongscontainer of water source of heat/flame Note: Supposedly you can substitute galvanized nails for the zinc and Dranoâ„ ¢ for the sodium hydroxide, but I was unable to get this project to work using nails and drain cleaner. How to Make Silver Pennies Pour a spoonful of zinc (1-2 grams) into a small beaker or evaporating dish containing water.Add a small quantity of sodium hydroxide.Alternatively, you could add zinc to a 3M NaOH solution.Heat the mixture to near-boiling, then remove it from heat.Add clean pennies to the solution, spacing them so that they are not touching each other.Wait 5-10 minutes for them to turn silver, then use tongs to remove the pennies from the solution.Rinse the pennies in water, then set them on a towel to dry.You can examine the pennies once you have rinsed them. This chemical reaction plates the copper in the penny with zinc. This is called galvanization. The zinc reacts with the hot sodium hydroxide solution to form soluble sodium zincate, Na2ZnO2, which is converted to metallic zinc when it touches the surface of the penny. How to Make the Silver Pennies turn Gold Grasp a silver penny with tongs.Gently heat the penny in the outer (cool) part of a burner flame or with a lighter or candle (or even set it on a hotplate).Remove the penny from heat as soon as it changes color.Rinse the gold penny under water to cool it. Heating the penny fuses the zinc and copper to form an alloy called brass. Brass is a homogeneous metal that varies from 60-82% Cu and from 18-40% Zn. Brass has a relatively low melting point, so the coating can be destroyed by heating the penny for too long. Safety Information Please use proper safety precautions. Sodium hydroxide is caustic. I recommend conducting this project under a fume hood or outdoors. Wear gloves and protective eyewear to prevent getting splashed by the sodium hydroxide solution.
