the yellow water is not allowed to mix with the green. Analysis questions/answers 1. Q-Based on your observations in the lab‚ what do you think happens to the majority of water (not ice) at the poles? A-The majority of the water freezes because water is the only molecule that doesn’t sink‚ so the water becomes ice. 2. Q-Based on your observations in the lab‚ what do you think happens to most of the water at the equator? A-The majority of water at the equator

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

DOE - Design of Experiment DOE is an approach used to identify factors/steps that are contributing most to an observed variation in product specifications. The classical DOE focuses on identifying the factors that affect the level of a product/process response‚ examining the response and forming the mathematical prediction model. The modern DOE‚ introduced by Genichi Taguchi in early 1980s‚ applies in both product and process development to identify the factors that affect the variability of the

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

Tuskegee Syphilis experiment is the most infamous clinical study conducted in the United States between 1932 -1972. The study of natural progression of untreated syphilis in rural Africa American men‚ led to a forty year study which was controversial for reasons related to ethical standards; researchers knowingly failed to treat patients after the 1940s validation of penicillin. The patients with syphilis were never told they had it‚ were part of a case study‚ could leave the experiment at any given

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)

A SHORT HISTORY OF THE COST PER DEFECT METRIC Version 1.1. May 5‚ 2009 Abstract The oldest metric for software quality economic study is that of “cost per defect.” While there may be earlier uses‚ the metric was certainly used within IBM by the late 1960’s for software; and probably as early as 1950’s for hardware. As commonly calculated the cost-per-defect metric measures the hours associated with defect repairs and the numbers of defects repaired and then multiplies the results

The Milgram experiment The Milgram experiment came about by a Yale University psychologist by the name of Stanley Milgram. The experiment was to test how well the study participants were and the willingness of study participants to obey an authority figure who instructed them to perform acts that conflicted with what they thought was right. He concluded people obey either out of fear or out of a desire to appear cooperative even when acting against their own better judgment and desires. Stanley

Bread Mold Experiment Mold is something that we often take for granted‚ as something that makes us have to throw the bread away or the cheese smell bad. Mold is‚ in fact‚ a fascinating organism which has had many different uses over the years and our lives would not be the same without it. Most of us know that food seems to become moldy more quickly in the summer than in the winter when it is colder. Food in refrigerators seems to keep longer than food left out in the sun. Is this true? Does temperature
