potato, vegetable - whether the potato is cooked - what the solute of the solution is Possible Outcome Variable: - change in length of potato core - percentage change in length of potato core - volume of solution left - change in weight - percentage change in weight My chosen outcome variable will be the percentage change in the length of the potato core. I have chosen this because this outcome variable will give us a clear set of results which will enable us to draw a clear
Affirmative Action Helps Qualified Minorities Affirmative action doesn't require a company to hire the local percentage of women and minorities, qualified or not. The program determines the percentage of qualified women and minorities available to a company, then sets flexible goals, to be reached in good faith. As a result, numerous studies show that minorities who land their jobs through affirmative action are not less qualified than their colleagues. Critics of affirmative action often
3.8 to 3.59. This is explained by the higher increase in the average inventory (37%) than the increase in cost of sales (29%) during 2005. This means that the rate at which inventory is sold is dropping • The vertical analysis shows that the percentage of total current assets to total assets increased from 50% to 52%. This means that IQ has not made major investments in the business during 2005. Woqod The analysis shows the following findings in terms of Woqod’s liquidity: • The horizontal
usually negative. There is an alternative scenario where demand will increase as price does so too. This happens only in the case of Giffen goods, where elasticity is positive. The formula for price elasticity of demand is: Percentage Change in Quantity Demanded Percentage Change in Price One determinant of price elasticity is the number and closeness of substitutes there are available for a good. The closer the goods are, the greater will be the price elasticity of demand of that good. The reason
Preparing Benzoic Acid from Benzylalcohol Planning (a) Problem The aim of this experiment is to synthesize benzioc acid, with the highest possible yield, by oxidizing benzylalcohol. Hypothesis We expect the percentage yield to be about 50% due to several processes such as cooling and filtering. Possible Variables - Time - Temperature (of water) - Filter Planning (b) Apparatus/ Materials - Round bottomed flask under reflux - benzylalcohol - HCl - Na2O4
that I obtained were percentage increase or decrease in the length of the potato. I used the following instruments to collect my results: Cork Borer (size 5), Measuring cylinder x2, Test Tube rack, Three test tubes, Vernier Calipers, Scalpel, White Tile, Brush. No attempt at great accuracy was made. The experiment was only an indication of what length of potato chip `I should use. I decided to use the three cm lengths of potato chip because it gave a bigger percentage change therefore I
calculate the percentage change in mass so that I can compare the different results with each other. I will calculate the percentage change by : Change x 100 Original · Controlled Variables The main control variables for this experiment are : Each of the 5 buffer solutions should have the same volume of 50ml and the same concentration. If one beaker had more than another then there would be more solution to act on the meat therefore tenderising it more. This could alter the end percentage change in
impure citric acid required to neutralise a known volume of 1.0 M sodium hydroxide. Consequently, by calculating the correct volume of pure citric acid that would be required to neutralise this volume of sodium hydroxide, I can calculate the percentage purity of the citric acid. Calculating the Amount of Citric Acid ------------------------------------- In order to make this experiment a good titration, I must use a reasonable amount of citric acid. This is so that the amount of citric
of a Concentration of Water on the Mass of a Potato Aim: My aim is to find the percentage change of mass when a small piece of potato is placed in to molar sucrose solution Apparatus: * Molar sucrose solution 0.0 - 0.5 * Potato * Cutting board * Knife * Weighing machine * Glass test tube * Glass test tube holder Plan: - ======= My plan is too find the percentage change of mass of a small piece of potato when placed in to molar sucrose solution by using
react with hydrochloric acid. This will tell me if the concentration of hydrochloric acid affects the speed of reaction. Variables ========= I could change: the temperature, the percentage of hydrochloric acid, the number of marble chips, or the size of the marble chips. I will change the percentage of hydrochloric acid there is for the marble chips to react with. I will keep the temperature, the number of marble chips, and the size of the marble chips the same. I will do all of
0.8 molar (the highest.) We then left each test until the next lesson, and then took the measurement of the potato chips once more. This is my results table: Concentration Initial length Final Length Percentage difference Initial mass Final mass Percentage difference 0 molar (water) 5 cm 5.15 cm 3 % 1.69 g 1.76 g 4.14 % 0 molar (water) 5 cm 5.2 cm 4 %
as the water, of higher concentration inside the potato cells, flows down a concentration gradient into the solution, which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict that when the solution is 0.5M the percentage change will be 0.5x%, and when the solution is 0.25M strength I hypothesise the change will be 0.25x%. Variables Description: Dependant Variables The dependant variable is plotted on the y-axis
the crack cocaine of gambling and once you start there is no way to stop. It has the same side effects of being addicted to drugs or being an alcoholic. My pamphlet lists specific facts about the poker machine such as the winning percentages. The winning percentage is programmed by the owner of the poker machine and is usually set at about 20% which very low. This means for every dollar that is put into the machine about 80% of it is defiantly going to be lost. This fact alone would make me
(point A), the more energy is converted to kinetic energy while the ball is dropping and then to elastic potential energy (E.P.E) while it is static on the floor (point B). At this point the ball looses a percentage of its energy to sound and heating the floor. I know that it is a percentage of its energy that it looses rather than a fixed amount because I know that the more energy the ball has the louder the
certainly a poverty-level lack of income won't help in child rearing. Education is another important factor to consider. The United States Department of Education reported the national average percentage of high school seniors who graduated during the 1992-1993 school year was 71.1%. Maine's percentage was 74.3, while California posted 67.9% (1). I believe this is due to a much smaller population, which, in turn, produces smaller schools. Student-to-teacher ratios tend to be much smaller. I graduated
Education in Ohio; for the last few years the number of gifted children in Ohio has been growing steadily. This year for the first time the percentage of children in Ohio that were identified as Gifted and Talented finally equaled the percentage of children who were served in Special Education Classrooms. There is only one small problem with this statement. The percentage is equal only if you count the students who are identified as being Talented and Gifted, not served. There are currently only 11% of

it must be learned. While this is often done through experience, education courses for individuals prior to their becoming parents, and close evaluation of questionable homes could enhance parents' knowledge and the childrens' well being. A high percentage of abusive parents have histories of physical and emotional abuse inflicted upon them during their childhood. Thus, they were deprived of parents who taught them how to be good parents. Child abuse scenarios that seem tragic to others are ordinary
least bi-lingual. H&R Block also has an opportunity to open temporary offices in parts of the country that would benefit consumers requiring an employee to speak their native language. The U.S. Census Bureau has also indicated an increase in the percentage of the nation’s population that is college educated. This may pose a threat to the tax preparation industry. A person that has received at least a 4-year college degree may obtain the knowledge to prepare their own taxes, thus eliminating their
policies. The federal government?s current system has too many quirks which end up hurting the people that financial aid is supposed to help. The federal government should change its financial aid policies to take several more factors, such as the percentage of educational expenses paid by the student, into account. Under the present system, all students applying for federal aid file a form called the Free Application for Federal Student Aid (FAFSA). This form is meant to figure out the amount of
