Beetroot Experiment We are trying to find how the temperature affects the rate at which the anthocyanin pigment leaves the cells, and at what point does the call wall melt. Beetroot Experiment =================== Task ---- We are trying to find how the temperature affects the rate at which the anthocyanin pigment leaves the cells, and at what point does the call wall melt. Please note the two results highlighted found in "test 4" have not been included into my results, as
In Roethlisberger’s article, he mainly discussed three Hawthorne Experiments, which includes the “illumination” experiments, the “Relay Assembly Test Room” experiment, the interviews about employee satisfaction and dissatisfaction, and the “Bank Wiring Observation Room” experiment. The purpose of the experiments was to study the effect of environment conditions, which include physical environment conditions and psychological factors, on workers’ productivity. Such as the level of illumination, rest
Radioactivity Experiments Aim: To determine the penetrating power and the range in air of the three radioactive emissions alpha, beta and gamma. Apparatus: * gm tube, * clamp stand, * the counter thing, * ruler, * set-square Method of penetrating power of Alpha particles, Beta particles & Gamma Rays: The equipment was set up as shown below to measure the penetrating power of each radioactive source. Geiger-Muller Tube Again the measurements were taken without
Experiments on Jews The freezing / hypothermia experiments were conducted for the Nazi high command. The experiments were conducted on men to simulate the conditions the armies suffered on the Eastern Front. The German forces were ill prepared for the bitter cold. Thousands of German soldiers died of freezing or were debilitated by cold injuries.The experiments were conducted under the supervision of Dr. Sigmund Rascher at Birkenau, Dachau and Auschwitz .The freezing experiments were divided
Parachute Experiment Prediction My prediction is that as the weight of plastercine increases the time taken for the parachute to reach the ground will decrease I think this because when the weight has just been dropped it is going slowly, but as it falls through the air it will gain speed until it reaches its terminal velocity. The weight does not change but the A.R gets bigger until it equals out the downwards force of gravity, so when the weight is larger it will have to fall further
For this experiment, the subject is a four year old boy named Jayden Lee, who is Alicia’s cousin. Jayden did not have stranger anxiety, but he rather felt really comfortable around Alicia considering how he was familiar with Alicia. Although it was Jayden’s first time encountering Dana, he was not intimidated because he knew that Dana was Alicia’s friend. Overall, he did not feel frightened when he was approached by Alicia and Dana. Furthermore, he also did not have separation anxiety when his mom
Electromagnetism Experiment Introduction: ============= I start the introduction with a question: Will increasing current in an electromagnet increase the power of the electromagnet? The electromagnet we will be making is a very primitive one compared to that of the complexity of modern electromagnets found in machinery, but the way it works is almost identical. Electromagnetic technology is extremely complex and because it is an electromagnet, the higher the current, the stronger
Neutralization Experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl), Sulphuric acid (H2SO4) etc. An alkali is a soluble
caffeine really affect our moods and emotions? The aim of the following investigation is to discover how our emotional state changes when we have had a certain amount of caffeine, compared to when we are caffeine-free. The participants chosen for this experiment were South Australian, year 11 psychology students currently studying at Tension Woods College. Hypothesis: With greater caffeine intake there will be increase in energy and happier dispositions. This hypothesis will be proven by the mood questionnaire
Electroplating Experiment Aim To find the amount copper gains or loses on the electrodes using different amounts of current each time during electrolysis. How the changing of current affects the electroplating of copper. Introduction Electroplating is generally carried out in order to improve the appearance or corrosion resistance of the surface of a metal by electrodepositing a thin layer of metal ion on it. The metal substrate to be coated is made by the cathode in an electrolytic
In a third experiment ninety-seven undergraduate participants volunteered and of them fifty-nine were women and thirty-eight were men. Fifty-three of them were in the stress group and forty-four were in the control group. Participants with surgery and medical conditions where stress inductions would be inadvisable were excluded from participation. During session one, participants sat in a small testing room that contained a chair and a desk with a computer. The computer presented the words in each
In this experiment the group went through completing one trial. In the fourth grade class there were 10/19 (52.6%) students aloud to participate in the experiment due to the absence of returned permission slips. There were 6/10 (60%) females and 4/10 (40%) male students that participated to conduct the experiment. The trial included the separations of genders. The group added one confederate in order to do a same sex grouping. Experimenter 1 conducted her experiment with all of the females with
Pythagoras Experiment Aim: To investigate the relationships between the lengths of the 3 sides of the right angled triangles and the perimeters and areas of these triangles. Task 1: a) The numbers 5, 12, 13 satisfy the condition. 5² + 12² = 13² Because 5² = 5x5 = 25 12² = 12x12 = 144 13² = 13x13 = 169 And so 5² + 12² = 25 + 144 = 169 = 132 b) The Numbers 7, 24, 25 also satisfy the condition. 7² + 24² =25² Because 7² = 7x7 = 49 24² = 24x24 = 576 25²
For my breaching experiment, I decided to break the social norm of looking at someone while engaged in conversation with them. Today, it is socially unacceptable and impolite to avoid looking at someone when talking to them. The background assumption for a typical conversation is that direct eye contact will be made more often than not; otherwise social norms are being violated. Avoiding eye contact during an exchange tends to dehumanize the person that is not receiving the eye contact. It is impolite
they can trust. There were two experiments that took place in the study. The first experiment was based on the eye contact and self-disclosure of the experimenter and the subject. The second experiment was the effects of the experimenter’s self-disclosure. On both studies, the purpose was to see how much the subject will self-disclose and respond when the experimenter approach them in a variety of ways (Jourard & Friedman, 1970). The hypothesis for both experiments
Catalase Activity Experiment Aim: to find out if different concentration of hydrogen peroxide release different amounts of oxygen when in contact with catalase enzyme. Risk assessment: Hydrogen peroxide is corrosive and can therefore irritate the skin and damage the eye if it comes into contact with these. To prevent this extra caution must be taken to avoid contact with the skin and goggles should be worn while carrying out the experiments. Other sharp implements such as the scalpel
Disappearing Cross Experiment Plan ==== I must produce a piece of coursework investigating the rates of reaction. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. There are five different factors, which affect the rate of a reaction (1) Temperature (2) Concentration of a solution (3) Pressure of gases (4) Surface area of solids (5) And catalysts. I have chosen to investigate the effect temperature
Methods The materials used within this experiment were chosen to reflect and enlighten a problem with moderation and its lack of tooth care this caused a demand for mostly household items for this experiment, of course teeth cannot be found within a house unless you own or have connections with a dentist or another type of tooth founding company. To get teeth for this experiment talk to your dentist or other tooth care enthusiast. The materials consist of nine sets of molars or k9 teeth in decent
appropriate past studies and chosen those that examine the notions of illusions and beliefs based on concepts of superstitious behaviour, superstition and superstitious rules. Many experiments in this field point at the fact of how causal learning could be distorted by biased beliefs. Langer (1975) has indeed done many experiments and has gone on to define the aspect of ‘illusion of control’. And this, Langer has defined as one that stems from an expectation of personal success probability inappropriately
Experiment on Electrical Resistance The electrical resistance of a material is its opposition to the flow of electric current (slowing the flow of electrons down). Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance. Resistance is a measure of how hard it is to move the electrons through the wire. A current is the rate of the flow of charge (electrons) and the resistance
