sharp increase in juvenile crime across the United States. From 1996 to the present there has been a slight decline from the statistics in 1995(OJJDP). What was the cause for this uprise in juvenile delinquincy? I will discuss 2 different theories to why there was such an increase in juvenile crime rates. I will analyze the rise of the "Gangsta-Rap" culture in the early 1990 ’s and how it may have affected teenagers that are in lower- income families. Many people believe that the increase in real

Science Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise‚ reliable and accurate. Strategy According to my results‚ as the concentration of STS solution increased the rate of reaction of my experiment was increased. Also as the concentration

performed two trials of nine different variables of reactions to determine what increases/decreases reaction rates. The variables we used are hot/cold and room temperature water‚ a equal mixture of HCL and water‚ A equal mixture of NaOH and water‚ either a whole‚ broken‚ or finely crushed Alka-seltzer tablet. The fastest rate average was at 0.04 s (finely crushed Alka-seltzer with room temp. water). The slowest rate average is 8.02 s (Alka-seltzer with cold water). Introduction The theory of

The US has recently reached the lowest unemployment rate： 4.5%. In this article‚ the author provided different aspects of US’s low unemployment rate and the result of such a low unemployment rate. Comparing to the unemployment rate (10%) after 2008’s recession‚ US is now reaching a relatively low unemployment rate. A low unemployment rate is one of the four macroeconomic objectives that economists always want their nations to achieve. Unemployment is simply defined as the state of being out of

Investigative Quest The purpose of this experiment was to find out how music affects the female human heart rate. Hypothesis My hypothesis is that female resting heart rate will increase as the music tempo increases. If the tempo is slower the heart rate will stay at resting heart rate or decrease. Variables The variables used in this experiment were: • The tempo of the music. • The subject’s heart rate. • The subject’s age. Controls The controls used in this experiment were: • How long the subject

Introduction The heart is an extremely important organ in the human body‚ and it must be able to adjust the heart rate for when a person is resting or for when a person is running. Heart rate is defined as the number of heartbeats per unit of time‚ usually per minute (Medicine-Net). The heart rate is based on the number of contractions of the ventricles. The pulse is defined as a bulge of an artery from waves of blood that course through the blood vessels each time the heart beats (Medicine-Net)
