mechanisms involved in the rewarding and motor-activating properties of these drugs” (Solinas 2002). In Marcello Solinas and Serge Ferré’s experiment

PROCEDURE My experiment was to test if color affects people’s sense of taste. My problem questioned, “Between a yellow sugar cookie and a blue sugar cookie, which cookie will people prefer?”. My hypothesis predicted that people will prefer the yellow cookie instead of the blue cookie because yellow is associated with happiness. To investigate my hypothesis I made cookie dough and then split the dough into two so i could color one half blue and the other half yellow. After cooking the cookies

This laboratory experiment aims to investigate the effects of lyrics in popular music on the ability to recall information as a replication of a study conducted by Blanton, Elmer and Yates (2006). In this study, 16 participants, ranging from 16-18 years old of mixed gender and race taking the International Baccalaureate program at a private international school in Singapore, studied a list of 32 words while listening to music with lyrics, music without lyrics and then were asked to recall the words

Many people conduct experiments resulting in explosive reactions without even understanding the science behind them. This can mean added danger for everyone in the lab, not to mention that it takes all the fun out of the experiment. One experiment in particular, involving Diet Coke and Mentos, can be easily manipulated in which several factors increase or prohibit the reaction. Contrary to popular belief, the reaction that occurs within this mixture is physical rather than chemical. All the components

the experiment (ex. temperature, the mass of marshmallows, volume of the water, etc.). When the raw data was processed, and the error analysis was made, it was then discovered that the results were significantly different from the actual energy content value. The percent error of this experiment of between 92% - 93%. As mentioned previously, many uncertainties and/or errors may have swayed the results, thus leading to this discrepancy. Not

contents then turned from a clear to dark yellow when mixed with absorbency (A400) of 1.370, the highest absorbency out of all tests. The reactant that was lacking in the control reaction was the enzyme. It is important to include controls in an experiment in order to see how one substance can affect many other substances or organisms. The other controls that could have been performed were the

Analysis This experiment took place in order to resolve the theories that the height of a cow’s hair whorl can predict the way the cow will react while being handled by the producer. The experiment took place at a cattle operation owned by Jim Hull in Philadelphia, TN when he was doing normal weigh-in and vaccination procedures with his animals. These procedures consisted of trimming of the tail, a vaccine and de-wormer injection in the neck on each side, and a new ear tag if the cow exceeded the

bugs (Rollie Pollie): The Effect of Isopod Behavior on Wet vs Dry Stimuli Abstract: There are two main purposes for this experiment. First, isopods were observed so that their behavior could be recorded. Second, we exposed the isopods to a wet cotton ball and dry cotton ball, to determine which stimuli the pill bugs (or Rollie pollies) preferred over the other. In the experiment, five different pill bugs were removed from their usual habitat and placed in a choice chamber 1 pill bug at a time for

VERBAL IMAGERY ABSTRACT The present experiment was conducted to study the effect of word length and presence or absence of visual cues on memory. It was conducted to see whether the presence or absence of the visual cue leads to better remembrance of the words presented to the participant. Also the length of the words was taken into consideration to test the memory for the words shown to the participants. This experiment was conducted with the sample of 82 participants wherein they were presented

Jerry M Burger's replication in 2009 of Stanley Milgram's Obedience study (1963, 1965 and 1974) specifically experiment 5, attempted to recreate this controversial and influential research whilst avoiding the ethical issues that the original study brought into play. How close was this to the original? What are the parts of the original that Burger was unable to recreate? Did these alterations effect the results when compared to Milgram's? What follows is my selection and explanation of key similarity’s

The Unplanned Human Experiment “Too spicy,” said Elijah, the son of Dr. Steingraber, after trying a food that some believe to be a stereotypical child’s favorite. In Steingraber’s essay, “But I Am a Child Who Does”, she writes about her accidental “human experiment”. Her experiment consists of her two children, Faith and Elijah, having a very particular food preference. Their taste perception was based solely on direct experience and was not exposed to any manipulating advertisements. However,

Introduction The purpose of the experiments that took place throughout this course was to experiment with our unknown bacterial species, citrobacter, note down the characteristics of it, observe the results, and take note of what changes took place while experimenting with it. After that we would put together all of the information, or data, that we collected over the course of this class and look through it to see if it has any connection with one of the species that is listed for identification

The acid-base titration experiment was a two week process. To begin the first week, a buret reading quiz was taken by each member of the group. When taking the quiz, it was recognized that 50 mL burrets can be measured to the nearest 0.01 mL (burrets are read from top to bottom). After the test was taken, a TA or the professor verified the accuracy of the reading. After testing the burret reading, the next step was to start the experiment by preparing approximately 0.1 M NaOH solution. First calculate

severe punishments on the victim in learning experiment context. The punishment is administered through shock generator means with switches grading to 30 that range from Sight Shock to Severe Shock: danger. The victim is a n E confederate and the study is based on the maximum shock that S can give. Twenty-six Ss complied with the commands of the experiment fully along with administering maximum shocks on the given generator. Fourteen Ss cut off the experiment at some point when the victim refused and

Nowadays, social science is becoming more and more popular to experiment and speak with data, especially behavioral economists. In general, they all take college students as subjects on campus, but the 2010 ‘The Economist’ reported that the experiment is different: two economists from the University of Toronto and the University of Chicago arrived in China. A factory that produces electronic products took an experiment from a Chinese worker. The workers did not know that they had become subjects

substance was. To do this experiment a crumbled up piece of aluminum was dropped into the unknown blue substance. When the aluminum was submerged into the blue substance it started to fizz, turn red and break into tiny pieces. After this occurred the beaker, which contained the aluminum and the blue substance, was placed onto a bunsen burner to be heated. After being heated for a while it turned clear and the red pieces turned into red powder. When we finished the experiment we still did not known what

The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants. Due to this the research hypothesis was supported

The purpose of this science fair experiment is to better understand the science behind the reaction time of human beings and what different factors are able to affect the outcomes of it. These factors may be age or different times of the day. In order to better understand this experiment clearly, research was done on subtopics relating to sensory stimulus in the human eyes. These subtopics include the structure of the human eye, the function of the circadian clock, and the performance of the sense

Medical Experiments Nazi’s during World War II conducted many cruel and unethical experiments on unsuspecting Jewish victims. The information gained by these experiments is valuable. However, some see the use of this information as cruel and downright offensive. Today, modern scientists are forced to deal with the unethicality of these trials. Today, there are strict relegations placed on human experimentation for scientific and medical advancements. Furthermore, we look back on these experiments as

During World War II, Nazi Germany performed various cruel and inhumane experiments on the Jewish and gypsy prisoners held in concentration camps. These experiments were categorized into three groups, military, pharmaceuticals, and racial advancement based experiments. There are many who say the data that was gathered during these experiments should not be used, but because the lives of the innocent were used to conduct these experiments, the data collected from some of them should be used because it could
