magnification. (http://inst.bact.wisc.edu/‚ © 2006-2013 Microbiology Laboratories) Gunasekaran (2005) defined staining as the method of artificially producing color in microorganisms to allow for the visualization under the microscope. He further stated that stains are used not only to make the organisms visible but also to understand their structure and chemical nature. Gram staining is a technique commonly used in the laboratory. It is used to differentiate two large groups of bacteria based

Simple Sentences 1. At the five year old’s’ first‚ chaotic soccer practice‚ the unnamed team’s confluence of kooky ideas led to the team name of “Shining Star Frogs”. Metacognition: For this sentence‚ the use of a prepositional phrase establishes context for the sentence in that it shows why the team is gathered. With the addition of the adjective “unnamed”‚ the need for collecting team name ideas is further exemplified. The greek affix con allows for better understanding of the word because con

Essay – Simple Living Give an outline of the attitudes to ‘’Simple Living’’ presented in texts 1‚ 2 and 3. Text 1 The first perspective on the concept ‘’Living Simple’’ is from author Elizabeth Scott‚ ‘’Simple Living‚ Recession-Style’’‚ an article from the website About.com‚ March 20‚ 2009. “The idea was to pare down and get rid of all the extra "stuff that we think we need‚ but don’t: extra belongings that clutter our homes‚ extra activities that pack our schedules to the hilt‚ extra food that

build machines that make our lives easier. The machines they build today started off with the basics‚ which are known as Simple Machines. Simple Machines are defined as the simplest mechanisms that use mechanical advantage to multiply force. These machines have either few or no moving parts‚ and use energy to work. This term is usually referred to the six classical simple machines; lever‚ wheel and axle‚ pulley‚ inclined plane‚ a wedge and a screw. They make work easier for us by allowing us

Simple Pendulum PURPOSE The purpose of this experiment is to study how the period of a pendulum depends on length‚ mass‚ and amplitude of the swing. THEORY A simple pendulum is an idealized model consisting of a point mass (sometimes called a pendulum bob) suspended by a massless unstretchable string. When the bob is pulled to one side of its straight down equilibrium position and released‚ it oscillates about the equilibrium position. The path of the bob is not a straight line but an arc

Mariel EXPERIMENT No. 2 The Simple Pendulum Abstract A simple pendulum is one which can be considered to be a point mass suspended from a string or rod of negligible mass and allowing it to sway back and forth in a place. The objective of this experiment is to observe the motion of a simple pendulum‚ study simple harmonic motion‚ determine some factors that affect the period of a pendulum‚ and measure the value of acceleration due to gravity by use of a simple pendulum. The materials used were

Goals The purpose of the lab experiment is to explore simple harmonic motion (SHM). We will accomplish this through the validation of harmonic calculations and ultimately creating a time piece (oscillator) Method In part A (Simple Pendulum) we will measure the effects of mass on the period of the pendulum. We will also calculate the period using small angular displacements and compare the results. We will also explore the effects on the period when the angular displacement is not “very small”
