Mini-Lab Report Objectives: There were two major goals of the “Observing Bacteria and Blood” experiment. The first was to establish a familiarity with the proper techniques for using a microscope. The experiment focused on both the basic components of a microscope (i.e. how to adjust the knobs and levers for the desired result) as well as how do decide the proper objective to use for observing a specimen. The second goal major goal of this experiment was to practice observing live specimens

EC 12/19‚ 2010 Forensics Period 5 Lab: Make your own Dental Impression I. Objective: The objective of the lab “Look and Record” was to identify the castings of your own teeth. The lab was also used to see how important forensic odontoloogy really is. What can a forensic odonotologist see in a dental impression cast that can help identify an individual? II. Background: Forensic odontology is important in all cases. Impressions can determine many things in a case.

Lab 2 Sara Rodriguez Period 2 Purpose: What is the more accurate way to measure volume‚ by using displacement or by using a ruler? Hypothesis: If the method of displacement is used ‚ then the results will be more accurate than measuring the volume using a ruler. Materials: -250 mL graduated cylinder -Triple beam balance -A weigh boat -Ruler -Samples Procedure: 1. Gather materials such as ‚ samples‚ weigh boat‚ triple beam balance ‚ graduated cylinder‚ ruler and water. 2. Take the materials

Date of Experiment: September 10th‚ 2013 Organic Chemistry II – CHLB330 Name: Symone E. MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total

PROBABILITY and MENDELIAN GENETICS LAB Hypothesis: If we toss the coin(s) for many times‚ then we will have more chances to reach the prediction that we expect based on the principle of probability. Results: As for part 1: probability of the occurrence of a single event‚ the deviation of heads and tails of 20 tosses is zero‚ which means that the possibility of heads and tails is ten to ten‚ which means equally chances. The deviation of heads and tails of 30 tosses is 4‚ which means that the

reaction equation is as follows: Rate of reaction = k [H202]M [I-]N The value of m and n will be calculated from the various runs of the experiment holding either H202 at constant concentration or holding I- at constant concentration Experiment: My lab partner and I first assembled the apparatus that we were to use according to the sample that was used to show us how to conduct the experiment. We added room temperature water into the leveling bulb and filled until the bulb was about half way filled
