The Experience Machine: Summary of Robert Nozick’s ‘Thought Experiment’

Robert Nozick was an American philosopher who put forth the “Experience Machine” scenario in his book Anarchy, State, and Utopia. The “Experience machine” is one of the best known attempts by Nozick to refute claims of ethical hedonism; by imagining a choice between a simulated reality and the everyday reality. The essay will summarize Robert […]

Test and evaluate a linear position sensor

For my experiment, I chose to test and evaluate a linear position sensor, and identify a possible use for this sensor in every day life. The experiment was done using a variety of apparatus, as seen in the list below, and was set up as shown in the diagram which follows.Apparatus:Retort stand with two clamps100g, […]

Seligman experiments

More than thirty-five years ago Seligman and his colleagues discovered and reported on two experiments which were to begin an ever-growing field of research, and to fuel continuing debates (Overmeir & Seligman, 1967; Seligman & Maier, 1967). The astonishing feature of these studies was that when dogs were exposed to inescapable shock they adopted behaviour […]

Shoe Size Vs Height Based on Twenty Samples

The title of our investigation is ‘Shoe Size Vs. Height Based on Twenty Samples’. As you can interpret from this title, we will try to investigate if there is any correlation between shoe sizes versus height. We have chosen to investigate into this topic to see if these two quantitative variables roughly have a straight-line […]

Vivissection

Vivissection has been a large part of scientific research, education and product testing for centuries. The term vivissection can refer to any experimentation on animals, including non-invasive psychology research, product testing or dissection, even for medical or educational purposes. There is now a growing number of people, including scientists, who would like to see the […]

Experiment to determine whether caffeine can have an effect on the heart rate

Caffeine is an xanthine alkaloid, that is a known steroid that can promote hypertension and hyperactivity. It is commonly used in drinks that are supposed to “pick you up”. They are caffeine rich and give the drinker a boost of energy. It also has medicinal uses in aspirin and some weight loss drugs. It acts […]

Hypersensitivity Reaction

An experiment was conducted to investigate hypersensitivity type 1 (allergic reactions) and the effects that different doses (0.2 10-4 m and 0.4 10-4 M) of histamine had on the guinea pig ileum (tissue). The different effects that mepyramine and carbachol had on the guinea pig ileum were also investigated. A piece of tissue from a […]

To investigate how temperature affects the concentration

I predict that if I increase the temperature of the orange juice, the concentration of the orange juice will decrease. This is because vitamin C is a fairly unstable molecule, and the greater the heat the more vitamin C molecules will be broken down. It takes activation energy to break down bonds and as we […]

Experimental design

This experiment was done in order to investigate certain factors affecting the killing of the bacterium Escherichia coli. The two factors investigated were: a) the length of time of exposure to Domestos and b) the concentration of this agent on killing E.coli. The methods used in the experiment were serial dilution and pouring Petri dishes. […]

What Effect Does The Temperature Of Water

In this investigation I am going to mix a certain amount of rennin solution and milk, and record how long it takes the mixture to coagulate. I will repeat this procedure of mixing the rennin and milk when they are heated to 5 different temperatures and will leave them to coagulate in a water bath […]

Viscosity of Liquids

The goal of this experiment was to determine the viscosity of given liquids. Two different methods were employed, the first measures time of flow of several methanol-water solutions, from point A to point B. The second method involves dropping a foreign object, in this case a sphere, into a cylinder of glycerol and measuring the […]

According to McBurney and White

According to McBurney and White (2003), an experiment can be defined as “a research procedure in which the scientist must select subjects for different conditions from pre-existing groups” (qtd. in Marks, 2006). This experiment appears to fall into the category of quasi-experiment, and two of the main contributors to this are the seeming lack of […]

Statistical significance: sample size

Statistical significance within a study determines the confidence the researcher can have in the differences found between two or more variables of that study. In other words, this demonstrates how sure a researcher can be that the relationship found between two variables really does exist. Statistical significance can be tested using various methods, and the […]

Molecular polarity

These experiments helped us understand the importance of molecular polarity. This knowledge can now be used for the future to predict, for example, if two substances will mix or not. We can now do this by knowing that polar substances only mix with other polar substances, while non-polar substances only mix with other non-polar substances. […]

Animal Behavior

The Siamese Fighting Fish is the one of the model spices to study competition in animals because the male of this species exhibit typical aggressive behavior. The sight of its own reflection in a mirror will stimulate a ritualized series of responses toward the intruder. The purpose of this experiment is to describe the ritualized […]

Compare and Contrast One Laboratory and One Field Experiment

A laboratory experiment is where research is done in a highly controlled environment, where the level of control is very important. It is also to examine the validity of the hypotheses. It is an investigation where one or more variables would be changed under these controlled circumstances so that research can be done on the […]

Organised Unorganised – Psychology Experiment

The aim of this experiment was to investigate the role of organization in learning of meaningful words. It was like a memory test, through which one could conclude how organization helps in strengthening memory. Memory refers to the processes that are used to acquire , store, retain and later retrieve information. There are three major […]

Identifying a Constituent of Panacetin

This experiment was a continuation of Experiment two, with a slightly different question to be answered. In this experiment, we are trying to find the identitiy of the unknown component of Panacetin. This is answering question 2 of the two questions that were to be answered in experiment 2. The equation of this reaction is […]
