Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the

One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

November 20‚ 2013 Lab Report 1. Problem: To find the density of a Hershey chocolate bar. 2. Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. 3: Materials: 1 whole Hershey chocolate bar‚ ruler‚ triple balance beam‚ tray‚ calculator. 4. Procedure: First‚ find the mass‚ volume‚ and density of an entire Hershey Bar. Then‚ systematically‚ break off one section at a time to calculate the mass‚ volume‚ and density for 3/4‚ 1/2‚ and 1/4

laboratory workbook. 3. Then we determined the volume of the unknown solid by water displacement. We first filled a 100mL graduated cylinder about 1/3 of the way with water and we recorded the volume to the nearest 0.1mL. We carefully slid the unknown solid into the cylinder with water. We then recorded the new volume and subtracted the two recordings equaling the volume of the unknown. 4. We then calculate the density by dividing the mass by the volume. 5. We then remove the metal cylinder‚

physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s postulation that the speed of a light wave in vacuum has the same magnitude relative to all inertial frames‚ physicists thought that the propagation of light waves occurred in a medium called ether which permeated all space. The Michelson-Morley

Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse‚ blood pressure‚ respirations‚ hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
