Methods of Social Investigation Emma Woodmansee ’Describe how you would plan and undertake an investigation into why some of this College’s students do not complete their degree courses.’ (You have been given only 100 to finance the study; and one term’s sabbatical.) Define the variables in the given title After a Research Statement has been formulated it is very important that the researcher defines any variables within it. A variable is any word whose meaning may be ambiguous or which could

Course Title: Criminal Investigation Unit Number: Unit 3 2. What are the similarities and differences between an arson investigation and a bombing investigation? Arson is the intentionally setting of fires to property‚ persons‚ and vehicles. Bombing can be defined as the offense of using a projectile‚ or explosive weapon to cause alarm‚ panic‚ danger‚ or death. There are many similarities and differences between the investigation of a bombing and the investigation of arson. The similarities

An investigation into the specific heat capacity of a solid Introduction: In this experiment I investigated the specific heat capacity of brass and aluminium‚ in order to do this I arranged a series circuit with a heater‚ the heater would go inside the brass and aluminium and heat it for an amount of time in which I decided‚ I also used the voltmeter in parallel. This arrangement made me able to arrange the equation VIT= mcΔθ‚ since the electrical energy in would be equal to the mass times the

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

The crime scene examination and subsequent search should be done in a careful and methodical manner. After talking to the officer(s) who were the first ones on the scene and learning from them of any changes that might have been made to the scene since their arrival‚ such as turning lights on or off or opening doors or windows‚ start the examination by working your way into the body using great care to avoid disturbing or destroying any evidence as you do. Carefully observe the floor or ground surrounding

Hypothesis: the higher the concentration of hydrogen peroxide the faster the reaction will occur and the more foam will be produced. Aim: The aim of this investigation is to determine how the concentration of hydrogen peroxide effects the intensity of the reaction. Variables: Independent- The concentration of hydrogen peroxide. Dependant - The intensity of the reaction. Constants – The temperature‚ the amount of liver‚ pH level‚ test time‚ Materials: Solutions of hydrogen peroxide varying

Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pH‚ enzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where
