where I divided its mass by its density to get its final volume so that I can create the perfect submarine for the experiment; final density of the submarine‚ where I added up all of the mass of balloon‚ pellets‚ and rubber band and divided by the volume of sphere so that I get the final density of my submarine and test if my submarine flow appropriately. The lab experiment on the identity of the unknown metals went well except that I have made a little bit of error on my calculation of the

Aesthetics of Abstract Expressionism Project Prepared for Donald McIntyre Professor‚ DeVry University Project Prepared by Colleen Mitchell Student‚ DeVry University June 7‚ 2009 Modernism is one of the cultural movements which took place in the nineteenth to the twentieth century. This movement was sure to draw attention to the artists’ work of art mainly because of the complexity of the artist’s creativity and breaking away from the more traditional works.

Poster Abstract Postnatal depression PND in women after childbirth has been a major health issue for some time‚ this illness will affect at least one in seven women after giving birth. It is often undetected by the health care professionals and also been misunderstood out in the community. Sometimes PND can be misdiagnosed as baby blues. As for baby blues is when mothers are feeling miserable‚ weepy‚ tired and tense these types of feelings may occur during the first few days after a woman has

Practical Assessment 2 – The effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site

The reason for the experiment is to see which color from the light spectrum causes plants to grow faster. The prediction was that read light would cause the most growth in plants and that blue light would result in slower growth. The results did not support the hypothesis. Referring to table‚ one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less. Spinach is a long-day plant therefore it was able to grow better under a constant

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion‚ they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move‚ they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion‚ for example smell of cooking travelling around the house from the kitchen

ABSTRACT STRATEGIC CONTINGENCY PLANNING By Karen Scott-Martinet Fall 2006 The objective of this study was to develop a strategic contingency planning model to be used to fully incorporate emergency management and business continuity into organization structures. (For the purpose of this study‚ Emergency Management and Business Continuity were collectively referred to as “contingency planning.”) Presently‚ contingency planning is mainly done on an operational or tactical level. Current

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

Helicopter Experiment Prediction: As the mass on the helicopter’s copters increases‚ the speed taken for the rotors to spin down faster‚ this is because there will be more downward pull from gravity‚ as the terminal velocity for a paper helicopter is low. Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include‚ the helicopter
