Obtain a 30 cm length of bare copper wire‚ stirring rod‚ and 18 x 150 mm test tube. Coil the copper wire by wrapping it around a glass-stirring rod. Stretch the coiled wire until it is about 2 cm longer than the test tube. Leave wire tightly coiled near one end and stretched out and straighten toward the other. Weigh the wire and record it in the data table to the

Iodine Test for Starch Introduction and Hypothesis: In this experiment‚ we used iodine to test for starch in certain solutions. Iodine separates starch from polysaccharides‚ monosaccharides‚ and disaccharides. Starch is a curled polymer of glucose and iodine interacts with molecules‚ which changes the color of the molecules to a kind of black color. Iodine does not respond with carbohydrates that are not curled or coiled‚ thus the color stays yellowish brown. A black color result means that starch

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

Tensile Test Abstract The objective of this experiment is to test three specimens of different materials in a Tensile test machine and to calculate basic material characteristics such as tensile stress and Young’s Modulus. This report will explain in detail theory and procedures involved in such test and give all results obtained by group C2 on October 2013. Introduction Young’s Modulus‚ also known as Elastic Modulus is a material characteristic that represents stiffness and is defined as the

Vocational Aptitude Battery is the standardized IQ test of the military and most high school guidance counselors recommend this test to their “lost” students. Each enlistee/student that takes this test will know one of two things‚ potential career path or what work assignment they will be doing for the next 2-4 years. I myself scored well‚ any job in the military was available to me‚ and choose to be an Airborne Petroleum Supply Specialist. This test didn’t really help me as it does with most high
