Our aim is to choose and investigate variables of our choice and its effects using a simple catapult. Preliminary method - 1. Using a tripod, a rubber band and a long sheet of paper set a catapult. 2. Test it and observe which variables you will keep constant and which you will change. 3. Record the preliminary results into a table
Geological investigation is the first step towards the completion of a building and is considered as the most important step as it identifies the feasibility of an area for construction and determines how the foundations and preventive measurements to be set up for the building. According to Sadhi (2012), one-third of the construction projects are delayed and half of over-tender cost on road projects are due to inadequate geological investigation or poor interpretation of the data. According to Ferrer
Statistics Investigation In this investigation I have been asked to carry out a line of enquiry with the statistics provided within a Microsoft Excel spreadsheet provided by Edexcel examining board. There are various different statistics for different things, some examples include; age, IQ, year group, height, weight and many more. A total of 27 categories are shown on the spreadsheet. My teacher advised me to carry out two main tasks within the overall investigation. It was suggested that
temperature. I have decided to alter the temperature of the yeast and time the amount of carbon dioxide that will be given off at different temperatures. I have decided to time how much carbon dioxide is given off in five minutes. Throughout the investigation, I will keep the temperature the same as I have specified for each reading. For example, if I am taking a reading in which the temperature must be 5 degrees, I will make sure that the yeast is kept at this temperature. When I am altering the temperature
Statistical Investigation Introduction I have chosen to do this statistical coursework that uses data from 'Mayfield High School.' Although this is a fictitious school, the data is based on a real school. As the data has been collected for me, it is called secondary data. I believe that this coursework will allow me to illustrate my ability to handle data, use specific techniques and apply higher level statistical maths by being able to use a variety of methods in order to analyse
Shapes Investigation I am doing an investigation to look at shapes made up of other shapes (starting with triangles, then going on squares and hexagons. I will try to find the relationship between the perimeter (in cm), dots enclosed and the amount of shapes (i.e. triangles etc.) used to make a shape. From this, I will try to find a formula linking P (perimeter), D (dots enclosed) and T (number of triangles used to make a shape). Later on in this investigation T will be substituted
Mathematical Investigation In this report we were asked a number of questions about the solving of magic squares. The final goal was to fill a magic square in correctly. The information I was given was about the history of magic squares and information on how they work. I did not need any extra information. Investigation: What I had to do for this investigation was to fill in a magic square correctly. I chose to do this by answering the questions given to me and using my answers to
Osmosis Investigation The Problem When a piece of fresh beetroot is left to stand in a beaker of cold distilled water, very little pigment is released from the beetroot. When, however, a similar piece is placed into a beaker of hot water, pigment release happens more quickly and the surrounding water soon becomes coloured red. A possible explanation for these observations could be that the structure of the plasma membrane is affected by temperature. As temperature rises, the damage
Electrolysis Investigation Planning In this investigation, I will assess how changing the electric current in the electrolysis of acidified water affects the rate at which hydrogen gas is produced. The solution to be electrolysed is made up using acid and water. It is of little consequence what acid is used however in this case I will use Sulphuric acid (H2SO4). When H2SO4 is put in water it is dissociated and forms ions: H2SO4 → 2H (2+) + SO4 (2-) Ions are also present from
Statistical Investigation All graphs should be attached. An Investigation into the Relationships between the Heights and Weights of a Rangeof Studentsat Mayfield High Aim I aim to investigate the relationship between the heights and weights of a range of students from different demographics at "Mayfield High". Prediction I. I predict initially that the average male height will be greater than the average female height. That is due to biology stating that males are, on average
Pendulum Investigation Introduction In this investigation, I will try to attempt an experiment that will measure the time taken for a pendulum to oscillate for one complete swing; I will also explore and investigate the numerous variables that might effect the time taken to oscillate. Factors effecting periodic time =============================== The factors, which might affect the time taken for a pendulum to complete one swing, are: 1. The length of string 2. Weight
Osmosis Investigation Aim What happens to the mass of a raisin when you put it onto different sugar solutions? A sugar solution is made from glucose and water. A raisin is a dried grape. A sugar solution is inside a grape. Prediction In a weaker sugar solution the water goes in, so the mass increases. In a stronger sugar solution the water goes out, so the mass decreases. In a weaker sugar solution the raisin’s mass increase caused by osmosis, the particles are absorbed by the
Parachute Investigation Aim: The aim of this investigation is to see how the factors of terminal velocity affect it. Equipment: The equipment/ apparatus required for this investigation are: ü Large plastic bag-to make the actual parachute ü Two Styrofoam cups-represents “person”, holds the sand & measure sand ü Sand-acts as the weight of the “person” in cup ü 4 white string-attaches the parachute to one of the Styrofoam cups ü Small Ziploc bag-to contain sand and prevent from
Trolley Investigation Choosing a Variable Before I begin the investigation, I must first decide which variable I should investigate. Variables can be divided into 2 major groups: dependant variables and independent variables. In measuring the behaviour of a trolley the dependant variable is speed. This is because the speed will change when other variables are changed. An independent variable is a variable which cannot be affected by other variables. There are many independent variables
Electrolysis Investigation Aim To investigate how voltage affects the amount of a copper (Cu) deposited during electrolysis of copper sulphate solution (CuSO4). Variables ========= TEMPERATURE - Approximately 20° centigrade.The higher the temperature, the faster the ions move through the solution. Thus, more copper is deposited in the given time period. ELECTROLYTE (CONCENTRATION) - 100g per litre. The denser the solution, the slower the reaction. The slower the reaction
Pendulum Investigation Plan Aim To investigate how the length of a simple pendulum will affect the time for a full swing. Variables Length The length of the pendulum has a large effect on the time for a complete swing. As the pendulum gets longer the time increases. As the pendulum gets shorter the time decreases. Air resistance A big and light pendulum bobble would be affected by a major amount of air resistance. This might cause the pendulum to move in a different way
The Importance of Disaster Investigations for Systems Engineers - What is a Systems Engineer? In the modern industry engineering systems are becoming more complex by the day. Therefore a need for elite engineers i.e. the Systems Engineer, capable of applying a wide range of engineering disciplines to a variety of tasks from product design and development from requirements analysis to simulation to manufacturing and marketing etc… is essential.
