Methods for Recording Observation of Young Children’s Behavior Rating Scale A device that can be used by an observer to summarize judgment of the activity or behaviour that has been observed. A scale may have three‚ five‚ seven‚ nine‚ one hundred or infinite number of points on a line with descriptive statements on either end‚ and perhaps in the middle as well. Following a selected period of time‚ an observer records‚ his/her impression‚ thereby providing a quantitative estimate of what has transpired

Material Appendix B – Identifying Bacteria Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium‚ biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION Review the dichotomous

respiratory diseases or viral infections and people who have weakened immune systems are at greater risk. Pneumonia bacteria are present in some healthy throats. When body defenses are weakened in some way‚ by illness‚ old age‚ malnutrition‚ general debility or impaired immunity‚ the bacterial can multiply and cause serious damage. Usually‚ when a person’s resistance is lowered‚ bacteria work their way into the lungs and inflame the air sacs. The tissue part of a lobe of the lung‚ an entire lobe‚ or

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

INTRODUCTION The enzyme catalase converts hydrogen peroxide (H2O2) to water and O2. The evolution of O2 causes bubbling. Thus‚ catalase-positive organisms that are mixed into hydrogen peroxide will cause bubbling (catalase-negative organisms will not). This test is good for distinguishing between Gram-positive cocci in chains (catalase negative) versus Gram-positive cocci in clusters (catalase positive). The coagulase test is used to differentiate Staphylococcus aureus from coagulase-negative

It is thought that archaea and bacteria were diverged early in their existence because of all the dissimilarities between the two groups. Both bacteria and archaea are enclosed in cell membranes. Archaea have a single cell membrane that absences a peptidoglycan wall and also their genetic transcription and translation‚ the two main processes in molecular biology do not show the typical bacterial features‚ but are quite similar to those of eukaryotes. Archaea are more related to eukaryotes‚ even though
