The Effect of Sugar Type on Rate of Energy Production During Yeast Fermentation Sarah Sulon Biology Lab 111L Dr. Murray October 25 2010 Abstract The experiment was conducted to determine the impact different sugar types have on yeast fermentation. It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast

In this lab‚ caffeine was extracted from black tea‚ and green tea through a vacuum filtration‚ and a rotovap. The melting point of the sample of black tea was 219.12-236.05 ˚c‚ and for the green tea it was 176.22-227.6 ˚c. The % error of the melting point indicates how much error there was from the melting point taken experimentally. The % error of the melting point for black tea was 0.44%‚ and for green tea it is 3.15%.Since the theoretical melting point of caffeine is between 235-237 ˚c‚ we can

The Effects of Gun Control Law on Violent Crime Rates Emily JettCSCI N207Final Project12/8/2012 | Abstract: This paper discusses the relationship between violent crime rates in each state as well as that state’s corresponding gun control laws. The data is presented to provide information pertaining to the theory that stricter gun laws prevent higher rates of violent crime. Violent crime statistics were taken from The United Crime Report document from the Federal Bureau of Investigation’s website

EFFECT OF ROOM TEMPERATURE ON THE BURN-RATE OF A CANDLE BURNS Have you ever wondered whether a candle burns more quickly on a hot day‚ than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C‚ 25°C and 30°C. Hypothesis A candle in a colder
