2 September 2014 Chapter 1 Review 1. Describe the characteristics of science. A. The characteristics of science are observations‚ search for regularities‚ process the information‚ and self-corrections. Science is based upon observations that incorporate our senses‚ or instruments that extend our senses‚ to interpret natural experiences. Science is a searh for regularities. These regularities may include observed phenomena or patterns in nature. After observations have been recorded about regularities

Abstract: The purpose of this lab experiment was to discover genetically modified organisms. We analyzed our results and found that our sample was GMO positive. These results were attained through polymerase chain reaction and agarose gel electrophoresis. We came to the conclusion that the presence of a band in lane 4 confirms that there are indeed genetically modified organisms. Introduction: Overall‚ the main purpose of this experiment was to conduct gel electrophoresis combined with PCR in

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

load test Aim: To determine the strength characteristics of a rock using the point load test and visual judgement. Materials Loading device Loading frame Pump Ram Platens Rock Caliper Method (Standard‚ 2007) 1. Measure the dimensions of the rock which includes the diameter and length 2. Find the length to diameter ratio to determine which test will be used. If the ratio is greater than 1 use diametrical test. But if the ratio is between 0.6 and 1 use axial test 3. The axial test was

3. LABORATORY TESTS USED TO STUDY THE STRENGTH OF CALCARENITES There are 3 distinct methods or tests used to determine the strength of calcarenite which are needle penetration test‚ unconfined compression test‚ and direct shear box test. 3.1. Needle penetration test This form of test is done on site on an outcrop rock that is not disturbed; this is usually done by extracting a sample material for oncoming laboratory work. The penetration tests are done on two different sections of outcrop with an

To test the aptitude of the person‚ it requires manual dexterity whereby a joint in a person’s arm is controlled and predetermined stress in which the direction of the arm and the joint moves will lead to the deflection and it will be measured (Wagner‚ 1977). This experiment is widely known all over the world and it is usually used especially to capture the motor performance in a variety of situations. According to Bryden and Roy (2005)‚ they did the study to examine the influences of handedness

LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) In the event of a chemical splash to the eyes‚ flood the eyes for at least 15-30 minutes with water. Flush from the eye outward. If you were not wearing proper eye wear‚ a chemical could splash into your eye and would make it necessary to use this. b. Fire Blanket (2 points) Used in order to put out a small fire. If a small area of the lab caught

Lab: Energy Stored in Food Background Questions (5 points each = 10 points): 1. What happens to the molecules of the food that we eat during digestion? 2. What type of metabolism is this? Background information: In this lab we will attempt to set a variety of different types of food on fire and capture the heat energy that is given off. The heat energy from the burning comes form the energy stored in the chemical bonds of the food. The more energy in the bonds‚ the more heat the food will
