Who normally conducts the preliminary investigation? What are some of the actions the first responders can take once they arrive at the scene of the crime? Since the preliminary investigation starts when the first emergency call is received‚ it is typically administered by the patrol officers who are first to respond to the scene. First responders can either preserve or contaminate the crime scene‚ which can possibly result in either the success or failure of the prosecution. Accordingly‚ the steps

Science Coursework Trypsin Investigation Aim I am going to prove that temperature effects the rate in which the enzyme Trypsin breaks down milk substrate into amino acids. Investigation "We strongly recommend the use of Vanish Stain Removal Tablets in conjunction with a 900 spin wash at 70°C" This was found on a milk carton of a well-known drinks company‚ Nesquick. The major food group constituent of milk is‚ of course‚ milk. For my Science Investigation‚ I am going to test different temperatures

CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

Science February 6 2009 - February 19 2009 Conductor Investigation Calvin Chang 8.2 Stage 1: Planning the Experiment Introduction ! By “electric current”‚ I mean by the rate at which electric charges moves through a circuit‚ the electric charges can either be ions or electrons. They are measured in ammeters and the unit that is measured in is ampere which is the number of charges that passes through per second. There are many factors which would affect the electric current‚ like the voltage of

Exchange Principle states‚ “Any action of an individual‚ and obviously the violent action constituting a crime‚ cannot occur without leaving a trace.” It is hard to say Locard’s Exchange Principle was not disregarded. After three months of expert investigation it was found that the DNA evidence that was discovered at the scene did not belong to Jennifer or Noura. Also Noura’s own DNA was not found at all at the scene of the crime. It is very hard to understand how Noura could have made extreme violent

Why do girls do better than boys at school? Investigation Aim – With the use of covert participant observation and study of secondary data‚ I will be analyzing and investigation the question “Why do girls do better at school than boys?” I will come to a conclusion on whether this question is correct and if it is true or not‚ then explaining the reasons why they do better or why they do not. Hypothesis – We believe that girls do better in school and this is because most girls can multi task and think

PENDULUM INVESTIGATION Aim of the investigation The aim of the pendulum investigation is to see what will happen if I change a variable whilst I swing a pendulum and see the effect which it has on the pendulums time to complete one whole swing (from where it starts‚ to the opposite end‚ and back again). This will give me an insight into what will effect the time of the swinging of the pendulum‚ be it weight‚ string length‚ the angle‚ or the swinging point. Planning my investigation I will

Part One I have chosen to investigate Autistic Spectrum Disorder and how it can affect a child’s behaviour. Autistic Spectrum disorder (ASD) is a developmental disorder that is characterised by lack of social skills‚ aggressive behaviour‚ lack of imagination‚ difficulties communicating and repetitive behaviour. (Anderson et al‚ 2008) Children that have ASD can find it very difficult when dealing with social situations. This is because they lack the ability to read other people’s faces and emotions

Aim. The aim of this investigation is to find out how Slaters react to an increase or decrease of the temperature in its surroundings. Hypothesis The speed of the Slaters will increase when the temperature of its environment is increased or decreased from its preferred range‚ so it ensures that they spend less time in unfavorable conditions to avoid desiccation. Method 1. This experiment is done using a water bath to change and control the temperature being trialed. The water bath will have
