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

Introduction: The marshmallow experiment is one of the best-known studies in psychology that was conducted in the late 1960’s by an Australian-born clinical psychologist Walter Mischel at Stanford University. Back then‚ the study tested over 600 nursery kids and this experiment has been existing and continuously conducted by researchers until now. The instruction was that the children could eat one marshmallow immediately or if they could wait they would receive two marshmallows later. The purpose

EXPERIMENT 5 TRANSVERSE STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY

Organic Chemistry: CHP 225 Thomas Hsieh Experiment 2: Boiling Points o Date experiment was performed: September 16‚ 2011 o Objective: To determine the boiling point of organic compounds such as tert-butyl alcohol‚ sec-butyl alcohol‚ n-butyl alcohol‚ and an unknown. o Principle: Boiling point is the temperature at which gas and liquid phases coexist in equilibrium. At this temperature‚ the vaporization rate and the condensation rate are equal. The liquid and vapor reach a state of dynamic

EXPERIMENT 2: SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement

The Stanford Prison Experiment‚ conducted over 40 years ago‚ brought these ethical issues into the limelight and remains one of the most controversial studies in the history of studying human behavior. This paper aims to define ethics‚ describe risk/benefit ratio‚ provide a brief background on the Stanford Prison Experiment‚ and evaluate the impact it has had on psychological research. The Stanford Prison Experiment The Stanford Prison Experiment probably tops a lot of lists when

of doctors and scientist thinking that they were being taken care of. The men participated in an experiment called the Tuskegee syphilis Experiment were the men would partake in a medical study. This paper will examine how scientist took advantage of the men who participated in this experiment and neglected to tell them the truth. This topic really interest me because it took 40 years into the experiment to see that it was not scientific but a real case of cruelty to innocent men. So how is it that

previously carried out Stroop effect. The participants‚ 20 Richmond College students (10 boys and 10 girls) chosen by an opportunistic sample were taken into a quiet room separately‚ were presented with 6 lists of words‚ out of which 3 were congruent and the other 3 incongruent and the time taken for each participant to name the colour that the words were written in was measured and recorded. From this repeated measures design‚ the results were that participants took a considerably longer
