A successful crime investigation depends upon the collection and analysis of various kinds of evidence. Forensic scientists classify evidence in different ways and have specific ways of dealing with it. One major distinction is between physical and biological evidence. Physical evidence refers to any item that comes from a nonliving origin‚ while biological evidence always originates from a living being. The most important kinds of physical evidence are fingerprints‚ tire marks‚ footprints‚ fibers

Fred Kim Mr. Gillespie IB Music 12 April‚ 2011 Musical Links Investigation Music is a form of communication that varies distinctively among different countries just as each country has their own language. However‚ music does not only vary with region‚ but also with time period and the neighboring musical cultures. To investigate how two very distinct and different musical cultures can be connected through their musical qualities‚ I will compare the similarities and differences between romantic

when particles obtained cannot be divided further. Democritus called these indivisible particles atoms (meaning indivisible). How and why elements combine and what happens when they combine. Antoine L. Lavoisier laid the foundation of chemical sciences by establishing two important laws of chemical combination. (a) The Law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. (b) The law of constant proportions which is also known as the law of

Paper Cone Investigation Lisa Han 10MF Design Research Question: This investigation will determine how the sector sizes of the piece of the filter paper affect the terminal velocity for the cone to fall. The following will be kept constant meter ruler‚ stopwatch‚ and filter paper. Hypothesis: ‘If the sector size is the increase‚ then the terminal velocity will decrease.’ The reason is that if the sector size is bigger‚ the surface area of the cone will become smaller. If the surface area

French Revolution Historical Investigation Paper Imagine living during a time where if you thought something was wrong then you would be gruesomely executed by having your head sliced strait off your head. During the French Revolution there was a time where thousands of people were being executed using the infamous guillotine. This period of time was referred to as The Reign of Terror. During this time a group of extremist were in charge of the country. These extremists were not to be mess with

Investigation of Combustion of Alcohols Aim The aim of this experiment is to investigate the combustion of various alcohols. The alcohols will be burnt to heat up a test tube of water‚ I aim is to find out how much energy is produced when burning the following alcohols: Methanol‚ Ethanol‚ Propanol‚ Butanol‚ and Pentanol. Any form of burning is an exothermic reaction (heat is given out)‚ this means that the reactants energy is higher than that of the product. Alcohols react with

Samarpan Rai 30/11/012 Physics HL Investigation on Young Modulus Young’s modulus‚ also known as the tensile modulus‚ is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. Young’s modulus is named after Thomas Young‚ the 19th century British scientist. It is a very important concept that categorizes metals on basis of their elasticity. In the last lab‚ we were asked to find out the Young Modulus of two wires: Copper and Steel. I worked on Copper

Problem Overview The purpose of this proposal is to show that the absence of motivation and interest in team members during a project can drastically affect its result. If the team members have low morale or a disregard for their tasks and activities on a project they can really affect how a project turns out whether it comes out on time or within budget. Problem Discussion A poorly motivated team can unravel a well-built construction plan in the blink of an eye. An experienced project manager

The Story of My Search I have always had a great love for math and science. These subjects come naturally for me; therefore‚ pursuing a career as an electrical engineer is not a surprise. Prior to my research‚ my knowledge of electrical engineering was limited. I knew that math is a huge part of the career along with power grids and science. My goal for the research was to strengthen my understanding of what it means to be an electrical engineer and decide if I should pursue a career in this field
