Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

improvements in political science in regards to an extended republic in Federalist 9‚ then builds on his arguments in Federalist 10 and 51. In Federalist 9‚ there are five specific improvements to the science of politics that are discussed. These improvements are separation of powers‚ legislative checks and balances‚ an independent judiciary‚ representation‚ and‚ perhaps most importantly‚ the idea of an extended republic. Federalist 9 also speaks heavily of how these advances of political science reduce the

9-19-13 Dehydrating and Rehydrating a Hydrate Introduction The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample
