The Stanford Prison Experiment was created by a psychology teacher named Phillip Zimbardo. There was 9 prisoners and 9 guards. Those that were chosen were arrested one morning and taken to the station where they were blindfolded. An ad was put in the local paper asking for volunteers for this project. This experiment was to see the psychological effects of being in prison. After reviewing over 70 applicants‚ they narrowed it down to twenty-four candidates. The candidates were college students from

Baking Soda (NaHCO3) Lab (Stoichiometry) - Physical Science Name: __________________________________________________ Purposes: 1. Calculate theoretical mass of NaCl based on a known mass of NaHCO3. 2. Experimentally determine the actual mass of NaCl produced. 3. Calculate the percent yield for your experiment. Reaction Equation: NaHCO3(s) + HCl(aq) ( NaCl(s) + CO2(g) + H2O(l) Materials: safety glasses baking soda (NaHCO3) 1 M HCl and

that putting mentos in diet coke is a chemical change‚ but it is actually a physical change. This is because the pieces that caused the reaction are still there‚ but they have just been rearranged. This also means that changing some of the factors in this experiment might cause another physical reaction to occur on a smaller or even larger scale.(Science Buddies) What you see when mentos are put into diet coke is that the coke spews out of it’s container once contacted with the mentos. But have you

In the third article “Australian State Bans Cosmetic Surgery For Teens”‚ written by Dan Childs. The text is pretty clear about its opinion on cosmetic surgery on teens. It wants to ban cosmetic surgery because teens are not able to make such a big decision‚ when there body is still changing. Further on there are also many risks that comes with these surgeries‚ for example death or a heart attack. There are also people who think that cosmetic surgery on teens shouldn’t be banned‚ because the government

Experiment ANALYSIS OF SODA ASH The CCLI Initiative Computers in Chemistry Laboratory Instruction LEARNING OBJECTIVES The objectives of this experiment are to . . . • understand the titration curve for a diprotic base. • use the titration curve to calculate the percent of Na2 CO3 in an unknown sample of soda ash. BACKGROUND Sodium carbonate is an important industrial chemical. It is used in the manufacture of soap‚ glass‚ paper and as a source of alkalinity‚ that is‚ as a

"In the interest of...saving lives‚ is it acceptable to make use of data collected through mutilation‚ torture‚ and death" (Campbell‚ 16)? That is the question which has been rearing its head in scientific research since the end of World War II. As man has sought to quench his thirst for knowledge‚ lines of ethicality have been drawn to preserve the integrity of science‚ and provide a framework from which man can improve upon the quality of human life. In Nazi concentration and death camps‚ the gruesome

ABSTRACT What is the fastest way to cool a soda? In this experiment‚ 8 cans of soda were used to determine the fastest method the cool the can of soda. The four alternative methods were the freezer‚ the refrigerator‚ ice cubes‚ and also an ice bath. Using 2 cans for each method‚ and measuring the temperature at increments of 5 minutes‚ the experiment was complete when the temperature stabilized. In conclusion‚ the fastest way to cool a soda was the soda in the freezer at -2 degrees Celsius. The

Baking soda is basically sodium bicarbonate or sodium hydrogen carbonate. Sodium bicarbonate (Baking soda) is shown as a white powder which looks like salt. Baking powder contains an amount of raising agents which are E450 Diphosphates‚ E500 Sodium Carbonates‚ and Maize Starch. By heating this up there will be a release of carbon dioxide‚ which will be put into test in my experiment to prove my hypothesis. Baking powder and baking soda both produce carbon dioxide‚ which helps raise baked products

Allowing diet sodas in schools has always been a touchy subject for Americans. Many think it’s perfectly fine‚ while others don’t. I believe no type of soda‚ diet‚ or regular should be allowed in schools. Research shows that caffeine raises blood sugar levels. When those blood sugar levels rise‚ there is a connection between concentration levels and students. I guess that can be considered a good thing on testing days. To go along with that‚ diet sodas are known for having lower calories which
