None Such Island Gallery Introduction We performed a two-part experiment to gain a better understanding of bacteria through gram-staining. Gram staining is a differential staining method which results in the classification of two groups of bacteria, Gram-positive and Gram-negative. This technique is based on the fact that the gram-positive bacteria's cell wall has a stronger attraction for crystal violet, based on the presence of more peptidoglycan, then does the gram negative bacteria.
This is an iterative cyclical model of the research process: In the Introduction, you should clearly define each of the target constructs IVs and DVs and in the Method explain how each of them is operationalised measured. Serves to provide an overall focus the study - it is the study's goal.
Leads into specific, testable hypotheses. Hypotheses Follows on from the overall RQ s. A clear, testable statement, not a question. Concise and to the point. Is readily understood by others. Usually in future tense. Each hypothesis should be able to be tested via one analysis or one set of related analyses.
Identifies specific relationships between variables. Technically, each hypothesis should be stated using: Number or letter each of your hypotheses e.
For the lab report, you should have at one hypothesis for each of the major analyses you undertake and more likely several hypotheses for each of the ANOVA and MLR analyes. Brainstorming Your lab report should probably be based around one or two central research questions RQs.
To start off with, caste a wide net and generate at least half a dozen possible RQs. You may want to write down all the variables in the study. You may be able to generate useful questions simply by looking at the variables, the questionnaire and possibly the data itself but watch out for data snooping!
It would also be helpful to become familiar with the factor structure of the instrument. Your brainstormed RQs could then emerge from: Refining Whittle the questions down, e. Am I interested in the question? Will the available data allow me to tackle this question?
Your tutor might ask questions like: Define each of the DVs and IVs. What are your hypotheses? What analyses will you conduct? What type of research are you conducting?Laboratory Reports.
You will be required to write a laboratory report for each lab performed. These are due at the beginning of the lab period the following week.
Parts of a Lab Report A Step-by-Step Checklist A lab report is a recap of what a scientist investigated. It is made up of the following parts. Potential Hypothesis(es): State the hypothesis carefully.
Do not just guess; instead try to arrive at the hypothesis logically and, if .
Lab Report - Hypothesis: I can successfully add vectors. Introduction: A vector is a quantity that has magnitude (speed, force, and/or length) and direction. For example, if a person is traveling East at 60 mph, then s/he is traveling in the direction East and at a magnitude of 60 mph.
- Lab Report Identifying Unknown Substances by. Aug 02, · Absorption Spectrum of Plant Pigments By: Jessica Leonard Biology Lab April 1, Abstract The experiment consisted of using a spectrophotometer to determine the ability of a pigment to absorb different wavelengths of light in chlorophyll extract.
An absorbance graph was to be made and the hypothesis was that the spectrum graph. Purpose: The purpose of this lab is to determine the identity of an unknown liquid by measuring its density, melting point, boiling point, and solubility in both water and alcohol, and then comparing the results to the values for known substances.
Title: Enzymes Lab Purpose • To simulate the effects of pH, temperature, and enzyme concentration on the activity of different enzymes. • To determine the optimal (best) conditions for each of the enzymes.
