Flyne Anderson Experiment done - 30 September 2012 Report submitted - 02 October 2012 Chemistry 111 - Experiment 4 : Properties of Gasses Purpose: The purpose of the experiment is to learn about the properties of gasses‚ and identify them by their physical and chemical properties by combining different elements and observing how they react with each other‚ and outside influences. Materials/Procedure: I gathered my materials from the material list and set up my data table. I combined the zinc

molecules present. This will therefore make the experiment unfair‚ because the more pigment molecules present the more pigment molecules that can move out of the cell. Therefore the beetroot used should be freshly cut. pH The pH is also an important factor‚ as pH can have an effect on the weak interactions and bonds that bound the membrane together. To keep the pH constant it is important to make sure that the same surrounding are used for the experiment. Surface area. The surface area of the beta

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

compensation for participating in this experiment. These participants were divided into six groups based on where they were sitting. Design The Stroop Test was used in order to test the effect of interference on reaction time. This was done by using three different types of slides‚ each with either 20 words or 20 colored boxes‚ and recording how many words participants could read the color of‚ rather than the word itself. The colors used in this experiment were red‚ green‚ blue‚ purple and brown

Summary The Stanford Prison was an experiment to study the psychological effects and reactions of students pretending to be prisoners and guards. This study was conducted in 1971 and although it was suppose to have duration of 2 weeks‚ it finished after just 6 days. The experiment required 24 male students for the role-play and paid $15‚00 per day. Several volunteers answered to an ad on a newspaper and were selected after being interviewed. They were all healthy and there were no psychological

damage to 14 % of its forest trees. In this experiment‚ I will find out what consequences acid rain has on the germination and subsequent growth of cress seedlings. I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings will have to be in an enclosed system so the sulphur dioxide does not escape. The experiment is a simulation trying to model a powerstation

Abstract: This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do

Altruism: A Field Experiment Kamille J. Bernabe Master in Psychology Polytechnic University of the Philippines Graduate School Advanced Social Psychology Abstract Everyday life is filled with small acts of altruism. While we may be all too familiar with altruism‚ social psychologists are interested in understanding why it occurs. What inspires these acts of kindness? What motivates people to risk their own lives to save a complete stranger? Altruism as defined as the concern
