My favorite station was the one next to the Sea Lion Cove. That station was the best one that we went to. I liked it a lot because it gave us some thing interesting thing to do. In that station we had to do three things. We  had to compare the temperatures of three different kinds of material in ice-cold water. Their was a plain plastic bag, a plastic bag with something inside it , and then a bag with hair in it. There were thermometers for us to check the temperature of the different kind of stuff in the water.
    Anyway, the plastic bag with  out anything in it was suppose to represent an animal that has no fur. The second bag contained a blubbery kind of substance ( I think it was pudding) that was suppose to represent how warm it is for animal that had a lot of animal fat. The third bag had a lot of hair in it. That was suppose to represent an animal with fur in cold water temperatures. So, we put our hands in it and set the bag in the cold water. We felt how it feels to have all those kinds of things as an animal. We experienced that in cold temperatures like those it is very good to have fur and body fat to warm you.
 
     The Columbian Exchange was a time where everything was being traded. The new World was trading things with the Old world. This was a time that was both good and bad at the same time. There are many reasons why this time was bad and good. Although people started communicating with each other, and things that other people did not have was being traded, there were a couple of bad things that were involved for everyone.
     The goods things were mainly food, new items, knowledge, trade, and communication. People all over the world were trading things with each other.  People were able to get what they did not have in their areas. So the produce of different places were being brought to other new places. Merchants traded food such as onions, mangos, potatoes, tomatoes, and other different kinds of fruit and vegetables. Other new items were being traded all over, including knowledge. People even traded ideas and sometimes religion. This caused everyone to be somehow connected. Thier was a lot of communication throughout many countries and cities.
    There were a few bad things about the Columbian Exchange. Slaves and disease were also being passed around. Diseases that were carried in food or in other items were being caught by those that bought those items or those that were near them. Some people even brought them in them. Slaves were also a problem. Those poor slaves were being hurt and worked a lot. These are both good things and bad things about the exchange.
 
The Inca Empire fall was a lot like the Aztec Empire's fall. This was shown in the ways both empires fell. It was very alike because in their times they both were going through hard times. Both of the empires were having both internal and external  problems. The thing is they were not destroyed by their own people, but from the Spaniards. This two great empires fell drastically because of so many problems. Those problems got out of hand and made them come to their end.
    Both of these empires were going through internal problems with their own people arrived, that was a very bad thing. Also both of the Spaniard leaders came to the empires wihtout anyone knowing what would happen later, because the natives did not know their language nor who they were. Later though both of their kings were captured and killed. So without their leaders or emperors the empires soon were in chaos. Another of the Spaniards adventage was that they had guns and horses.
   Since these empires did not have these kinds of things yet, for them their was going to battle lost. One other thing that contributed to both the empires fall was disease. It weakend the people.
 
      This year has been a very great and memorable year for me. It has been stressing and very hard but, it really has been remarkable. I have so many great memories for this year, so it is hard for me to choose only one. There is now one thing that stands out against all my other memories. It is a little weird, creepy, and a little nasty, but when our teacher said it was just simply hilarious. This happened in Mrs. Baird's room one morning for our humor of the day. 
      As we were walking in I noticed Mrs. Baird kept smiling, then I noticed that were not going to be doing humor of the day on the computer so it must be some kind of written joke, or a story. So, everything was as usual and then when it came to our humor everything changed. Mrs. Baird was going to read us different kinds of poopies.  That was very funny, it was probably the funniest humor of the day that week or month. I will not describe what Mrs. Baird said about each one, but it was funny. That is one out of many great experiences and memories that I have had this school year so far. I hope that I take with me s
 
      Historians have many theories regarding the collapse of the Mayan Civilization. They are not sure which one is the  cause of such a great civilization to collapse. I think that this civilization collapsed not just because of one thing , but because of a combination of things.  In my opinion I think they collapsed because of over-population. As a result of so much people in that civilization other problems could have occurred. One thing I have learned about history that has happened to most of the places and empires that I have learned in school is that once a great civilization reaches its peak it gets over-populated. 
     Once there are too many people things get out of control and then later their whole civilization collapses. So, in this case I think that the Mayan Civilization collapsed because of being over-populated. Some of the problems that could have occurred with this main problem are as follow: not sufficient food supplies, water , rebelliance between inside cities,  and wars for power or land. The Mayan civilization was very remarkable but just as it came it left. The Mayan civilization did many things that were very advanced at that time, and it is still remembered today as a great empire, too bad it had to collapse so fast.
