tests for years. Testing in the schools has swelled and mutated and threatens to swallow our school systems whole. Standardized tests in the public school system have become biased and they are costly to school systems. In this presentation I will go over some of the cons of standardized testing. One is that the tests given to our students today are biased to our children that certain questions can only be answered by particular groups of students. The second con of standardized testing is that these

Tensile Testing Of Metallic Materials 概要： Tensile testing of metallic materials is specified according to European EN 10002 standard. In this article the terms‚ definitions and designation for tensile test made at ambient temperature is described. The test involves straining a test piece in tension‚ generally to fracture‚ for the purpose of determining mechanical properties. Tensile testing of metallic materials is specified according to European EN 10002 standard. This standards consists of five

aims to produce biodegradable plastic using cassava starch as its main component. Cassava starch was mixed with water‚ epoxydized soya bean oil (ESBO)‚ glycerol‚ and polyvinyl alcohol (PVA). The mixture was then compressed and tested. Three preparations were made from the mixture. The first preparation contained 50 grams starch‚ 50 grams water‚ 50 grams PVA‚ 2.5 grams ESBO‚ and 2.5 grams glycerol. The second preparation contained 65 grams starch‚ 65 grams water‚ 50 grams PVA‚ 2.5 grams ESBO‚ and 2

Using information about how you completed this ELISA experiment‚ outline a procedure for testing for antibodies in the blood. 9. Explain why in sudden outbreaks‚ it may be better to test for disease antigens rather than for antibodies. The antibodies are there to help and kill of the antigens‚ but don’t contain the whole DNA strand. The

known as the No Child Left Behind Act is one of the foundations that Standardized tests are built on. Rather than this Act working in favor of the students‚ it is actually diminishing the value of learning (Fisanick). The reality of standardized testing is that it is negatively affecting students through using their scores to determine their future‚ assessing a few skills and more

Theory Testing The theory that was being tested was the Diet Coke and Mentos Geyser. My children wanted to try and see if we could make the Diet Coke shoot out of the top of the bottle like the videos that they had watched on Youtube.com. How the experiment works is you open a package of Mentos and drop the entire package in the Diet Coke as fast as possible. The faster the Mentos drops‚ the more forceful the Diet Coke Geyser will shoot. What should happen is the combination

Reaction Rates of Barley Alpha Amylase with Starch at Specific pH ’s and Temperatures Page 1 Abstract Enzyme ’s are used as catalysts in certain reactions. They help lower the activation energy needed for the reaction to go to completion. At optimum temperature and pH the amount of collisions of substrate and enzyme is at its highest‚ any deviation from the optimum temperature and pH will result in the denaturization of the enzyme. The purpose of this experiment is to find the optimum
