Abstract Measurements are all subject to error which leads to the uncertainty of the result. Errors may come from systematic errors (deterministic error) or random error (not deterministic error). In this experiment‚ the group measured the diameter of sphere using different kinds of measuring devices (foot rule‚ vernier caliper‚ and micrometer caliper) in order to achieve accuracy in the scientific measurements. After experimenting‚ it was revealed that the micrometer caliper has the lowest percentage

Abstract This experiment followed an exact protocol from EDVOTEK® Kit #17. This kit was designed to use western blot analysis to detect proteins from Non-fat powdered milk. The experiment had to be run two times before the expected outcome was reached. However‚ after the second attempt‚ it was successful. The gel ran well‚ and the proteins from the gel were successfully transferred to the membrane provided in the kit. Introduction The name western blot was given to the technique by W. Neal Burnette

Measurement of stiffness of rock from laboratory and field tests Naeem O. Abdulhadi & Amjad F. Barghouthi Arab Center for Engineering Studies (ACES) ABSTRACT This paper compares the deformation modulus of rock measured from laboratory and field tests which were carried out as part of the site investigation works for a major project in Irbid‚ Jordan. Laboratory resonant column and torsional shear tests were performed at different confining pressures whereas ultrasonic velocity tests were

Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns

Experiment 6 titled “Organic Chemistry” and the purpose of this lab is to get familiar with some organic functional group and test certain reactions of selected functional groups. To do the first part of the experiment (combustion test)‚ instructor demonstration in hood‚ and record the observation. Part A (combustion of toluene) pour 1 milliliter of toluene into a evaporating dish and ignite it with a flaming wood splint. Most importantly put the flame with a watchglass. Part B (combustion of ethyl

Jamie Kim Mrs. Shaw Chemistry Honors 3 September 2014 Bubble Quality Lab Hypothesis: Bubble quality is most positively affected by the mixture of sugar and dish detergent due to the sticky consistency of sugar when emerged in liquid. Procedure: First of all‚ three cups were labelled according to their solution. Then‚ a teaspoon of dish soap and two-thirds of a cup of water was added and mixed to make cup#1. Next‚ a half teaspoon of table sugar was added to the same control solution and was

Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield benzoin. Thiamine
