The purpose of the first part of the experiment was to produce a chemical compound which was the alum crystals by using aluminum‚ potassium hydroxide and sulfuric acid. After the compound was present‚ the purpose of the second part of the experiment was to make sure that the compound that was formed in the first half of the experiment was actually alum. Some of the experimental techniques that were used in this experiment was filtration using the Büchner funnel vacuum filtration‚ recrystallization

Abstract This experiment was an alteration of Elizabeth Rauscher’s 1993 study on the Mozart effect. Instead of testing spatial ability‚ this experiment aimed to determine the effect of classical music on recalling‚ for the purpose of improving studying methods. We hypothesized that exposure to classical music during the encoding stage would have a significant‚ positive effect on recall. The participants for this experiment were an opportunity sample of high school seniors‚ 17-18 years

accurate because: The scientist gathers the information he/she observed using all senses‚ while conducting an experiment‚ by analyzing the industrial pond to ponds located farther away. Therefore‚ in order to present evidence of a study‚ a visual and tested observation is required for factual documentation from the person/s in any field of study‚ presenting evidence to support an experiment/test. 2) The "Examples of Tasks" I selected for the Scientific Method Step: "Ask a question" is accurate

a simple species‚ such as the fly‚ also made him popular with the public. The main focus of the book involves Professor Dethier designing and performing various experiments. Each experiment done by Professor Dethier is very simple‚ therefore the reader is informed‚ and as Professor Dethier adds interesting facts about the experiments of the fly the reader can interpret it easier. Professor Dethier begins the book by explaining how science and scientist are often misunderstood. He continues by

American psychologist‚ Solomon Asch‚ conducted an experiment in 1951 on conformity on a group of students from Swarthmore College. The goal of this study was to observe how far an individual could be influenced by public pressure‚ and in the end‚ possibly pick incorrect answers that were valued on facts‚ universal knowledge‚ and personal belief. Asch believed that conformity was a process in which people are pressured to change their behavior for the sake of fitting in. Asch wanted to prove that

color change from the blue biuret reagent. Questions A. Which of the test tubes are the positive and negative controls? The experiment illustrated that: The Positive controls were Test tube #1 Egg white and #2 Pepsin. The Negative controls were Test tube #4 Distilled water and #3 Sugar. B. What conclusions can be made about this experiment? The experiment concluded that proteins can be found in enzymes such as pepsin and animal products such as egg whites‚ but absent in carbs such as sugar

design such that the results obtained are attributed to the manipulation of the independent variable. In other words‚ if what you see is a function of what you did‚ then the experiment has internal validity.” (p. 235). When conducting research with experimental designs‚ researchers usually have two groups to test their experiment. These two groups are called “the experimental group” and the control group”. Experimental designs can provide a tremendous amount of power and control over understanding relationships

tulvingCraig and Tulving 2011 The experiment was based on the original Craig and Tulving in 1975. This experiment investigated how deep and shallow processing affects memory recall. In the recreation of the experiment our aim was to investigate structural‚ phonic and semantic meaning. To do this we needed a camera to film the experiment‚ around 20 year 8 students and a classroom. In this investigation our independent variable was how 11-13 students would memorize different objects in different
