Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

of three separated components Research Question: Is it possible to separate salt‚ sand and iron filings from each other in a mixture‚ to figure out the percentage of each component in the original mixture? Background Research: In this Investigation‚ I will be separating sand‚ salt‚ iron fillings in a mixture and finding their percentages. Iron is a magnetic solid which is incapable of being dissolved in water. Salt is a non-magnetic solid which is capable of being dissolved in water. Sand is

incubated at 37◦C for 18-24 hours. Observation shows there is a bright red growth but no change in the appearance of the medium. This indicates no lactose fermentation‚ however since there is growth‚ this means the bacterium in gram-negative. Mannitol salt agar: This medium was inoculated with both specimens and incubated at 37◦C for 18-24 hours. There being no growth and no change in appearance of the medium for either organism‚ this indicates there was no mannitol fermentation and they do not tolerate

Composition of Cobalt Oxalate Hydrate Experiment 12 Robbie Kinsey Partner: Debnil Chowdhury Chem. 1312-D TA’s: Russell Dondero & Sylvester Mosley February 9‚ 2000 Purpose The purpose of this lab was to determine the percent cobalt and oxalate by mass‚ and with that information‚ the empirical formula for cobalt oxalate hydrate‚ using the general formula Coa(C2O4)b.cH2O. Procedure The powdered cobalt oxalate hydrate was weighed

consisted of over seven parts however‚ because of the amount of time given in summer lab we had to save time and cut some days out. We were able to do this by being given our own Salicylic acid (SA) prepared for us instead of having to used wintergreen to make it and recrystallize it. In addition‚ we skipped the qualitative test of our purity for SA and Aspirin (ASA). The first part of this experiment is the preparation of ASA from SA were‚ we prepared our aspirin from the collected salicylic acid. A

Purpose: To observe epithelial tissue by using a microscope to compare prepared slides. Introduction: Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialized to form the covering or lining of all internal and external body surfaces. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as

1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask
