Josh Huggard Mr. Neale SBI3U1 November 6th‚ 2014 Spit and Armpit Lab Partners: Kara Washer and Josh Young Abstract This lab shows the use of salivary amylase with strong and weak starch mixtures to break down complex carbohydrates into simpler sugars. This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It

In this local experiment‚ the goal was to use a polyacrylonitrile (PAN‚ (C3H3N)n) in addition to a chalcogel. This chalcogel is efficient at adsorbing I2 gas. Although just the chalcogel itself isn’t mechanically stable especially if it is to be used in the field for actual radioactive iodine capture. By creating a hybrid substance with the PAN and the chalcogel in a mixture‚ the theory is that they can create a mechanically stable efficient iodine capture method. This experiment did not study the

Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average

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

Grip bar strength test is the most commonly used in vivo test for assessing impaired limb strength (forelimb and/or hindlimb) caused by pathology progression or during therapeutic interventions. Specifically‚ Creative Biolabs conducts the grip strength test to phenotype strains of transgenic mice and evaluate novel chemical entities for their effect on motor performance. Introduction of Grip Strength Test The grip strength test is a simple and rapid noninvasive method widely used in scientific research

Introduction The purpose of this laboratory was to first test the effect that increasing water content would have on the workability of fresh concrete‚ completed by way of a slump test. The second part of the laboratory was to check what the influence of a superplasticiser would have on workability of fresh concrete‚ this was completed by completion of a Vebe test. 2.

Timothy Johns Christian Howard Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If

1. Introduction The Jominy end-quench test is a technique that has the ability to harden the steel by quenching. It is an essential feature of materials that determine the material’s selection for particular applications. The different types of steels and alloys that are used for hardening in an industry are done by this test and considering that this test is a standardised experiment [1]. 1.1 Aim The specimens that are used in this test are normalized in accordance with the standards. The purpose
