population and settlement

Today for the first half of class, the people who had to leave early took the test. The people who already took the tests got their scores back. I got a 70 percent. This is worse than I thought but I just passed so I guess I did okay. We started a new lesson on population and settlement. We looked through a powerpoint while we were waiting for people to finish the test. There are over 7.6 billion people on the Earth right now. This is being increased by 73 million people per year, 200,000 people per day, 8377 people per hour, 149 per minute, and 2.5 per second. 90% of the world's population growth takes place in developing countries.

I also took notes on some of the slides we didn't get to yet. Crude birth rate is the number of births per 1000 of the population. Crude death rate is the number of deaths per 1000 of the population. The rate of natural increase or RNI is produced by subtracting the death rate from the birth rate. This gives us the annual natural growth rate for a country or region. Net migration growth is the difference between the number of persons entering and leaving a country during a year.

Guns, Germs and Steel Day 2

Today in class we watched a video about Guns, Germs and Steel. We talked about what all great civilizations have in common. These three things are advanced technology, large population, and a well organized work force. We also learned the definition of pre history. Pre history is 13,000 years ago when civilization relied on hunting and gathering. Papua New Guinea is one of the only places that you can go to and still find people hunting and gathering. In Papua New Guinea, they used a specific tree to get food. Inside of this tree is sago. This is the food that New Guineans get from the tree. It is often turned into a dough and eaten.

Guns Germs and Steel Day 6

Today we finished the video. Tomorrow we have a test. I am not prepared for this. I have written everything that we have written in our notes back into my blog so hopefully he will let us use them. I think that I will be fine even if he doesn't let us use our blogs. I just need to study my notes for a while tonight. Hopefully this test will bring up my grade to an A. I only have a B in Human Geo and Health and both are a 89%.
