More Population Pyramids

    Today in class we finished the rest of the powerpoint and looked closely at population pyramids of specific cities. We identified the shape of the graph and determined the cause of the shape being that way. For example, Ann Arbor Michigan has a lot of 15-29 year olds. This is because there is a military base in the town. Many young kids go there to be recruited in the army. You wouldn't see many 8- year olds preparing to enter combat, which explains the low number of elders. Also, we went on the population pyramid website and looked at random countries pyramids. We determined the cause for the shape of their pyramid by inferring some particular components of that area or region that could factor in on the population and the ages. The website gives you the pyramid, the percentage, and the actual number of people in that certain age group. It was interesting to see and utilize this website.

Constantine and Christianity

    Today in class we continued to talk about Christianity and we touched on Constantine. Some of my notes are below: Conversion of Constantine (AD 312) Roman emperor Constantine has a vision before the Battle at Milivian Bridge he sees an image in the sky of a cross and the words Ev ToUTw Nika ("In this sign, conquer") Orders troops to put a cross on shields they win Edict of Milan in AD 313 Christianity becomes a religion which is recognized/approved by the emperor it continues to gain strength By 380, it becomes the empire's official religion Chi-Rho: first two letters of "Christ" in Greek  Decline of the Roman Empire While Christianity strengthened, Rome weakened  Military: too week to defend huge area Economy: taxes too high; widening gap between rich and poor; trade disrupted Social: Who cares about public affairs?; disloyalty; population decreases Political: division of the empire (Constantine moved the capital to Byzantium)

Non-Test Day

    Today in class we were supposed to take our Renaissance and Reformation test. Our class, however, voted to not take it. A lot of kids did not want to take a chance in hurting their grade, including me, It has taken me a very long time to get my grade up, so anything I can do to keep it where it is or get it higher I will do. I was a little uncomfortable with being tested on the i formations since we only took 2 days to talk about it and we crammed so much of the reformation in to one day. We "took" the test, but it didn't count. I didn't know a lot of the answers on the test because we never talked about them. I don't know when we would have, so if the test counted, I would have gotten those answers wrong and gotten a bad grade. The test was all on the reformation too, which I thought was weird because then we would have wasted time on the Renaissance when we could have learned about the Reformation in a larger amount of time and then we could have taken the t
