The effect of different music styles on blood pressure Experiment by: Claire Mouser and Garrett Swearingen Written by: Claire Mouser Written: 3/13/14 Abstract: The purpose of this experiment was to inform teenagers about the effect different genres of music can have on your heart rate. The heart rates of teens are affected differently when they listen to rock versus classical music. The goal of this experiment was to find out whether teens heart rates would change while they listened

Lab: Sampling Bacteria Purpose: Refer to handout sheet. Materials: Refer to handout sheet. Procedure: Refer to handout sheet. Pre-Lab Questions: 1. Why is one dish being reserved for the class as a "control"? Having a controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar

purpose of this lab is to isolate a bacterial population from the normal throat flora. A streak plate method will be used to obtain a pure culture of a Gram positive coccus genus of bacteria. Several biochemical tests will be performed to aid in the identification of this unknown bacterium. Biochemical tests are a series of tests used to identify certain bacterium The various tests that are used in this lab are the catalase test‚ oxidase test‚ blood hemolytic test‚ MSA‚ blood agar‚ and PEA/ab

Mechanisms of Blood Flow in the Human Forearm during Mental Stress‚ Following Isometric Exercise and after Occlusion ------------------------------------------------- 1. Introduction A common technique in measuring blood flow in the human forearm is by venous occlusion plethysmography. The fundamental principle is that if the venous return from the arm is blocked‚ the forearm will swell at a rate relative to the rate of the arterial inflow (Whitney‚ 1953). However‚ the rate of increase in volume

Introduction: What is Blood Pressure? Blood Pressure can be defined as the force per unit area exerted on a vessel wall by the contained blood in the heart‚ and is measured by millimeters of mercury (mm Hg) (Marieb‚ 703). Each time the heart beats (which is about 60-70 times a minute at rest); it pumps out blood into the arteries. There are two types of pressure recorded that can determine your blood pressure. Your blood pressure is at its highest when the heart beats‚ pumping the blood. This is called

Jennifer Hauss March 4‚ 2015 Bacterial Transformation Lab Report Introduction In this lab‚ the goal was to transform the bacteria e-coli to glow in the dark (or under a black light). Four plates were set up with agar in them for the bacteria to feed on and grow. Changes were then made to the bacteria. One plate was the control plate‚ having only the LB or agar for the bacteria and negative pGLO‚ which is the liquid not containing the plasmid. This is the plate that was compared with the three

French Fries vs Bacteria Introduction After the Chipotle scandal of having E. Coli‚ I wondered what other bacteria can possibly be on foods that we consume. In addition‚ eating my french fries the day after I bought it‚ I wondered how long it could be until there was bacteria growing on the french fries. These two experiences in the last few months triggered me to become interested in what bacteria is and how harmful it can be. In order to do this investigation‚ one must study various types of french
