to increase in direct translation to the concentration increasing. The theory surrounding this lab was to see in practice how density could be determined with displacement and then to determine whether the density does in fact increase directly with the concentration.

Essay #2 Tina Taylor William Jennings Bryan argues against the gold standard. What arguments does he give against the gold standard and why does it oppress the common people? William Jennings Bryan was against the Gold Standard because it artificially lowered inflation. In today’s times the Federal Reserve can print as much money as it wants and also control how the money circulates in the economy by buying and selling bonds. With the gold standard there was an infinite amount of gold that

oxygen increases so does the number of fish observed. However‚ when the dissolved oxygen reaches 14 ppm the number of fish decreases to 10. So‚ 6ppm and 14ppm‚ 8ppm and 16ppm‚ and finally 10ppm and 18ppm‚ have a similar number of fish observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If the amount of dissolved oxygen is increased‚ then the number of fish observed will increase. 3
