Science Experiments Essay

What are the five steps of the scientific method? 1.)Begin with curiosity: BY “on the basis of theory, prior research, or personal observation, pose a question.” 2.)Develop a hypothesis: once you have the question, form it into a hypothesis, a prognosis would be evaluated 3.)Test the hypothesis: Design and lead research to accumulate experimental proof 4.)Analyze the evidence gathered in the research: figured out if the theory was right or not 5.)Report the results: share information,…

1. This experiment compared the spatial selective attention between “neurologically normal young adults” and split-brain subjects by measuring response times when presented unilateral and bilateral visual arrays. 2. The purpose for this experiment was to gather information about spatial selective attention, and to investigate whether “an independent focus of attention is deployed by each surgically separated hemisphere in a visual search task, such that bilateral stimulus arrays can be scanned…

memory, but if less than seven obstacles recall would be from the primary memory. • Experiment 1 (5 pts.) – Purpose: To determine if Proactive Inhibition affected primary memory or secondary memory during a recall test. – Method: Twenty students were either tested individually or in small groups of 2 or 3. They were given eight lists of words…

methods are used frequently in studies of this nature. On top of these two strengths, the compliance of this study was also one hundred percent. Participant’s compliance during the study provides the most precise data possible. Like most of the experiments used, the sample size could be larger. A larger sample size that also includes women would make the study more generalizable to the public. Having such a small sample size and a short trial period prevents the researchers from finding further…

1. One might "operationalize" or define jealousy into measurable parts by recording the physical response of the subject that researchers are trying elicit the emotion of jealousy. Several physical responses' of the subject that could be recorded are: the heart rate, the blood pressure, the amount of stress hormones, or the region of the brain that becomes active. These are also examples of physiological measures, measure that provide data on bodily responses. One could also define jealousy by…

correctly but when asked as part of a group most participants would conform to the wrong answer given by the actor. The results of this experiment were that 32% of participants answered wrongly. These results show conformity to a group norm as even with a clear answer participants will conform to the actors wrong answer. Crutchfield 1955- the aim of Crutchfields experiment was to see if people would conform to a group norm even when answering the question individually .Crutchfield used the…

For a large number of people, their experience with lab reports and scientific documents will be limited to a lab or two they are required to take in college for a general education credit. Skills learned in these classes will most likely be quickly forgotten and never used again. However, for those that work in a scientific field, writing lab reports is a fundamental skill that will be used time and time again. Lab reports can be used to express many different types of data and prove a variety…

This is in response to the recent survey done at College Community Hospital (CCH) in which staff’s main cause of dissatisfaction concern was the slow turn-around of lab test. As an assistant administrator to CCH, I am proposing to find solution to this problem. A performance improvement (PI) project is initiated in order to address this problem. Shaw and Carter (2015) have stated that “the overarching reason for change in healthcare organizations today is the need to improve the quality of…

Question #1 Word Count: 245 P1: The Critical lure in Experiment 1 is a word that was related to the studied words but wasn’t actually present in the original list. Studied words that were not omitted were recalled with a 75% confidence level. Unrelated lures stuck out like a sore thumb at (80%), and weakly related lures showed little significant, but critical lures were recalled with false confidence of (58%). This data demonstrates that we falsely remember things related in subject matter but…

After testing the D. magna with alcohol, the results showed a negative effect on the D. magna. After recording the normal heart rate in beats per minute (bpm) before the experiment, alcohol was applied to four different D. magna for each percentage of alcohol. The three concentrations of alcohol used were 5%, 10%, and 20%. Once the differences in heart rate were recorded for each of the D. magna, the averages of the four differences in heart rate for each concentration of alcohol were calculated…
