yellowish color Precipitated a very light bluish color Conclusion: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write net ionic

Stanford´s Prison experiment‚ searching for an explanation for the violence in the USA prisons. He wanted to know if this behaviour is due to the personalities of the guards (i.e. dispositional) or due to the prison environment and structure (i.e. situational). He later gave class in some of the best universities of the world; Yale‚ NYU and Columbia. His also known for other two works:The Time Paradox and The Time Cure. I´ll try to explain in the simplest way I can this experiment. Zimbardo used a

The aim of this experiment was to replicate the Primacy effect‚ which investigates the effects of ascending and descending performances on attributions of intellectual ability‚ illustrating that individuals’ perception of another individual is influenced by their first impression of that person to the detriment of all subsequent impressions. The design included independent groups‚ and the 46 participants over 16 years old (25 males and 21 females) were chosen through convenience sampling. The latter

Robbers Cave Experiment Jamie Allen Drake University Abstract Robbers Cave experiment was completed by Muzafer Sherif in order to question whether groups are able to work together for a common goal for the whole group. Muzafer showed us through 3 stages a) In group formation b) Friction phase c) integration stage. This experiment was made up of 22 Caucasian middle class boys who shared similar backgrounds coming from a two parent home and protestant background. The boys were complete strangers

Beginning with Science 02: Scientific Investigation For this assignment you will do two things: Part I: Evaluate one experimental design. (10 points) Part II: Design your own experiment using the scientific method. (40 points) Review each scenario below‚ and choose one to complete for your assignment. Each scenario contains specific questions that will ask you to provide examples‚ explain your suggestions for improvement‚ and refer to the lesson. Be sure to respond to each question in complete

and Oak Trees experiment Due to their large size oak trees become shelters and nesting sites to very many wildlife species‚ so if one were to remove or decrease availability of these oak trees then one might expect the abundance of the animals that use oak trees as a home would decline as well. In this experiment‚ we will be testing whether or not the availability of oak trees in an environment will affect the distribution and abundance of robins. The hypothesis of the experiment would be as follows:

Abstract:The Stanford experiment was performed by psychologists Craig Haney‚ W. CurtisBanks‚ and Philip Zimbardo. Their goal was to find out how humans deal with a position ofpower and a position of being powerless.. However‚ even though their experiment ended upwith great results‚ still‚ they were not able to finish it and the stanford prison experiment wasclosed after only 6 days. We reporformed the Stanford prison experiment that was done psychologists Craig. We broughtordinary college students

Are laboratory experiments useful? Laboratory experiments are easy to replicate and help to find how the Cause and effect of relationships can be established. Laboratory methods usually have High levels of control over extraneous variables. One of the major strengths of laboratory experiments is‚ control. The more variables you have control over‚ the easier it becomes to draw conclusions about the effect of the individual variable on the dependent variable. Laboratory experiments allow for high

Evaluation I think my evidence is reliable because the anomalies in my first results were the same as the ones in my second results. The graph made a straight line with a gradient that gets deeper that is what I predicted. To improve my experiment to make it even more reliable I could use a more accurate ammeter and a larger range of results as well as more checks. The ammeter I use could be more than two decimal places‚ and I could get a lot of results and put them on one graph to

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher
