    This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

    various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction In the first article‚ which was a research paper called “Surface runoff

    Lab Report 1  Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

    Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

    Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately
