Today in Human Geo class, we took
a test on the documentary we spent the last few days in
class watching called "God Grew Tired of Us". During the test we
were allowed to use our blogs as our only resource. We were expected to transfer
our notes into our blog before, and if we did so, this was a sort of reward.
Before we took our test though, we all ate cupcakes in honor of Erica's
birthday. :)
Once everyone finished the test,
we started to take notes on a new unit on population pyramids. Population
pyramids are what we use to analyze the growth or decline of fertility,
mortality, and migration in cities. The three basic shapes are;
1.
