Investigation of Factors Affect Osmosis in Potatoes Aim The aim of the following experiment was to investigate the effect of varying the concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From the preliminary, we were trying to find out how osmosis actually occurred in potatoes, and gave us a vague idea on what the main experiment would be like. This preliminary will aid my prediction
An Investigation of Factors Affecting the Rate of Osmosis Introduction Osmosis is the movement of water molecules across a semi permeable membrane from a region of high water concentration to a region of low water concentration. [IMAGE] A semi permeable membrane is a membrane with very small holes in it; they are so small that only water molecules can pass through them. Bigger molecules such as glucose cannot pass through it. In actual fact water molecules pass both ways through
Investigation of Factors that May Influence the Way People Learn In this task I am going to explore the factors that can influence the way people learn. Learning is a difficult word to give a definition to as it can be used in many different contexts. However, most people take the word ‘learning’ to mean acquiring new knowledge or skills. Some types of learning can result in a permanent change in behaviour or cause us to act in a certain way. In this task I am going to explore some theories
An Investigation into Factors Affecting Resistance of a Wire Plan: The possible variables I could use to find out factors affecting resistance are material wire is made of, length of wire, temperature and cross sectional area of wire. I will use cross sectional area of wire and length of wire because I think it will be hard to draw conclusions from the material of wire. I am not doing temperature because it would be hard to get results from and I think they wouldn't be as accurate.
An Investigation of the Factors Affecting the Period of a Pendulum I could investigate the following factors: * Angle of displacement * Length of string * Pendulum weight I am going to investigate and see if varying the length of string will affect the period of the pendulum. My prediction is: The longer the string the longer the period. The period will be longer as the pendulum has farther to travel. My theory is demonstrated below. Pendulum A has a shorter string. This gives
Investigation into the Factor of Light and Dark Affecting Woodlice Predictions It was expected that a woodlice would prefer a damp, dark, but moderately warm surrounding. Normally one would expect to find slaters under logs or concrete slabs in one's garden. Under these large objects, the sun cannot reach directly; therefore it is darker, damper and colder than the surroundings. Nevertheless, in winter we do not see woodlice crawling around very often, and, also at night, it may actually
Investigation in to the factors that affects the rate of fermentation of Glucose Aim: To investigate the factors that affects the rate of fermentation of Glucose. Background knowledge. ENZYMES Fermentation is a form of an anaerobic respiration where by glucose is partially broken down so only a small amount of energy is released. The yeast cells use the enzymes, ZYMASE to break down sugars unable to obtain. GLUCOSE CARBON DIOXIDE + ETHANOL(+ENERGY) C6 H12 O6 6CO2 + C2H5OH (210KJ) Enzymes
An Investigation Into the Factors Affecting the Voltage Output of a Solar Cell My aim is to try and find out how much the voltage is affected when exposing different sized areas of a solar cell to a light source. From this I will also establish the energy of each photon and approximately, the number of freed electrons, which can make an electric current flow. I know that light consists of packets or quanta of energy called photons. When electromagnetic radiation such as light shines on
Investigation of Factors that Affect the Rate of Reaction Between Limestone PLANNING SECTION Aim: To investigate the factors that affect the rate of reaction between limestone and hydrochloric acid. Introduction: Text Box: CaCO3 + HCl = CaCl2 + CO2 + H2O calcium carbonate + hydrochloric acid = calcium chloride + carbon dioxide + water In this investigation I am trying to find out what influences the reaction rate between limestone and hydrochloric acid. The reaction is: The
Investigation into the Factors that Affect the Enthalpy Change During a Displacement Reaction The Task -------- To investigate the factors affecting the enthalpy change during a displacement reaction. Background Knowledge ==================== In this investigation a displacement reaction will be observed. A displacement reaction occurs when more reactive metal displaces, (or removes) a less reactive metal from a solution of its salt. Also known as chemical bullying because
Investigation of the Factor that Affects the Change in Temperature Between Iron and Copper Sulphate In this investigation I am going to investigate a factor that effects the change in temperature between copper sulphate solution and iron filings. The variable involved in this investigation are: · The volume of copper sulphate · The mass of iron filings added · Rise in temperature · Concentration of the copper sulphate In this in investigation my input variable that I
that is needed to prove guilt and this is here investigation comes into play. Up for discussion will be the concept of criminal investigation, solvability factors, and the supervision of investigative cases. The importance of each cannot be defined individually. They have to be taken as a whole to ensure that the investigation runs smoothly. Firs is finding out what it means to manage criminal investigations. By definition, managing criminal investigations “offers a series of guidelines that recommend
Solvability factors are factors considered in determining whether or not a case should be assigned for a follow-up investigation. If the case scores a certain amount of points, it can be referred. The primary objective of the preliminary investigation is to determine who committed the crime and to apprehend the criminal. The evidence collected should support the occurrence of a crime, the identification of the defendant, and arrest and subsequent conviction. The initial steps in the preliminary investigation
Solvability factors are defined as factors considered in determining whether or not a case should be assigned for a follow-up investigation (Dempsey & Forst, 2016, p. 304). Another asset of associated with MCI is it provides the use of a managerial system that assigns grades according to solvability, which permits detectives to focus on cases that possess a chance of being solved (Dempsey & Forst, 2016). Although, case assignment procedures may vary between police departments, some general solvability
Crime scene investigations are the center piece to any conviction. They are pivotal to collect all information and evidence for each case. When done correctly, a crime scene investigation is creating a high chance of conviction. They are many factors that go into a good crime scene investigation. With technology advancement, this has created several new methods in catching a criminal and getting a conviction. Forensic science is the term. Forensic science is developing so rapidly that criminals are
Investigating the Effects of An Abiotic Factor on the Frequency and Distribution of a Freshwater Invertebrate (i) Planning ------------ Introduction ============ Before a complex biological study can be planned and formulated, the terminology in the title above must be clarified. The investigation requires a sound knowledge of ecology, which essentially is the study of organisms, whether they be animals or insects, and their relationship with the environment in which they live
temperature effects the reaction between magnesium and hydrochloric acid, the experiment will show whether the reaction will speed up or slow down with the change in temperature. Temperatures will range from room temp up until 70 degrees. The investigation will be a fair test because all quantities will remain the same for each test, each test will use the same amounts of hydrochloric acid and same size of magnesium, also the concentration of the acid will also not be changed. APPERATUS;
