Investigating a Crime Scene Denise Swank Bryant & Stratton College Criminal Justice: Research Paper Mr. Frank Chmarak December 2011 Investigating a Crime Scene On TV shows like "CSI‚" viewers get to watch as investigators find and collect evidence at the scene of a crime‚ making blood appear as if by magic and swabbing every mouth in the vicinity. Many of us believe we have a pretty good grip on the process‚ and rumor has it criminals are getting a jump on the good guys by using the

Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food

Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued

Investigating Snells Law Investigating Snell’s Law Research Question: The effect that the angle of incidence of white light has on the angle of refraction from one transparent medium to another. Introduction: Snell’s law state: When light passes from one transparent medium to another the rays of light refract (bend). Snell’s law (Law of Refraction) states that: n*=sinⅈsinr=n2n1=V1V2 for the purpose of this experiment we will be proving that: sinⅈsinr=n2n1 or n1sinⅈ=n2sinr where

This is important for the students to appreciate the knowledge of chemistry that is still new for themselves. Personally‚ I think that this chapter is an interesting chapter as it revealed the way of scientist produces the material around me. It also gives me new knowledge of the uses of chemical substances that I usually found in the laboratories. I hope‚ by learning this chapter‚ I will be more interested in learning chemistry as it will help me in the future. All the equations from this chapter

Azo compounds are usually intensely coloured because the azo (diazenediyl) linkage –N=N-‚ brings the two aromatic rings into conjugation. This gives and extended system of delocalized π electrons and allows absorption of light in the visible region. Azo compounds‚ because of their intense colours and because they can be synthesized from relatively inexpensive compounds‚ are used extensively as dyes. azo dyes almost
