Money for Some Art essays

Money for Some Art essays When looking at the question, should the government give financial support to the arts? You have to think about what type of art should the government get involved with and if they should even spend the money on art. If the government was to give financial support to the arts it should be for things that are government affiliated, such as schools, parks, and memorials. Art in schools allows students to expand there horizons and find things that they are good at, whether it be painting, building, computer graphics, or drawing. As for parks, art gives parks a certain flavor and it gives people reasons to go to parks because they want to look at the artwork that is placed there. Memorials, like the Vietnam War memorial or the Pearl Harbor memorial are thing that the government should give financial support to because of the importance of United States history. However the government gives money to so many things already that money for art projects can almost seem worthless when compared to the numerous dollars that the government spends already. Things like the war on drugs, the war on terrorism, NASA, and medical science. Though art is important in its own right it takes a back seat to programs that are in place to save lives. Overall the government should give financial support to some government-affiliated places. Art is an important part of society but the money given to these art programs should be kept within reason. ...

Ice on Fire Chemistry Demonstration

Ice on Fire Chemistry Demonstration Set real water ice on fire using a simple chemical reaction. This easy chemistry demonstration is sure to please! Ice on Fire Project Materials calcium carbide chips or granulesice2-liter beaker Set Ice on Fire Pour about a teaspoon of calcium carbide in the bottom of the beaker.Fill the beaker with ice.Use a long handled lighter to ignite the ice. Alternately, you could secretly place a bit of calcium carbide in a large bowl, fill it with ice, and toss a burning match onto the bowl of ice. How It Works As the ice melts, the water reacts with calcium carbide to produce acetylene gas, which is flammable, and calcium hydroxide. The reaction proceeds according to this chemical equation: CaC2(s) 2 H2O(l) → C2H2(g) Ca(OH)2(s) The acetylene produces a burst of flame when it is ignited. More acetylene is produced as the ice melts and reacts with the remaining calcium carbide. Safety Dont add the ice or expose the calcium carbide to water/humidity until you are ready to perform the demonstration. You dont need a build-up of acetylene.Its fire this demonstration should only be performed by an adult.Its advisable to place a plexiglass blast shield between the container and the audience, in case the beaker shatters from thermal stress or the fire expands outward too much. These are not expected to occur, but are reasonable safety precautions.As always, its good to wear safety goggles, gloves and protective clothing, plus it looks cool for the demonstration.Perform this demonstration away from other sources of flame or from flammable materials.
