The Columbian Exchange is trade between the New World and Old World. The benefit of the Columbian Exchange is that there was a larger variety of food, and they were able to try new foods. The Columbian Exchange also began communication between the New World and the Old World.


            A bad thing about the Columbian Exchange would be the fact that diseases were spread between the New World and the Old World. Diseases in the New World were spread to the Old World, and diseases from the Old World were spread to the New World. This was a bad affect of the Columbian Exchange.
 
      We went to the Fresno Chaffe Zoo on Tuesday. A lot of kids were saying that the zoo trip was boring, and they didn't learn anything. I personally loved the zoo trip. I loved all the animals. There were animals that were found all over the world. I thought that the tiger station was really cool, but there was only one tiger, and it was just sitting down. I wish it was more active. There weren't very many tortoises at each exhibit. There were only 1-2 tortoises of each kind. There was only one Radiated Tortoise at the zoo, and only one red-footed tortoise. There were 2 African Spurred Tortoises. 2 Giant Tortoises at the zoo. Also, I really liked the rainforest, it was hot in there, but the different types of animals were amazing. The Bird Show was magnificent. As one of the birds was flying overhead, this bird decided to poop, and landed on a girl in my core class. 

      I liked the Asian Elephants the most from all of the exhibits at the zoo. These Elephants were moving around and there were 2 of them. They were both massive! I saw one of them splattering sand over itself to protect it self from the sun's heat. The Asian Elephants seemed pretty solitary. None of the 2 elephants came close to one another. It was as if they were some sort of rivals. You may ask why the Asian Elephant exhibit was my favorite. It is my favorite exhibit because I had only seen 1 elephant before the 2 elephants at the zoo in my life. The first elephant I ever saw was wondering the streets of India with its master sitting on top. At first I was very scared, but afterwards I was very fascinated. This is why the Asian Elephant exhibit was my favorite exhibit at the zoo.

 
      The decline of the Inca Empire was caused by many things which are similar to the Aztecs. First of all, the Spanish conquistadors came. Both the Inca and the Aztec emperors thought that they were gods. They then let them into the empire. Both of the emperors were captured. Both Hernan Cortes and Pizzaro brought disease which killed thousands of people Both Hernan and Pizzaro did not have many men, but they had advanced weaponary such as guns and cannons, along with steel armor. They also had horses for transportation. The geography of both Cazco and Tenochtitlan was isolated. These are some similarities between the decline of the Aztec and Inca empire.
 
      One of my favorite moments was most likely when we found out we where going to place for battle bots. Ever since we were working on robots for tournament of technology, we though that the line follower was going to win, and the battle bot was going to lose. We were far from right, in fact it is the other way around. The line follower wasn't even close to winning. It was somewhere around last. On the other hand, the battle bot got third. When we were building our battle bot, we all made precautions against one-another's battle bots. We all had similar battle bots except for one. This one had a lifting mechanism. This one did not do very well. When it tried to lift a robot, it would tilt forward, and it would give the other team the advantage of pushing the opposing team out of the ring. 


     First thing we did when we got to the actual robotics tournament was go and look at everyone's robot and we would make a guess on how they would place. For the most part, we our guesses where right. Corbin, Prabhmeet, and I all realized that we were going to place for battle bots, and we did. the tricky part is that everyone is going to copy and improve our idea. We can either build off of our design or we can make a totally new design from scratch. I guess we will find out next year!
 
      The fall of the Maya civilization was caused by a series of events. I think that it started off with war among cities. This caused the soil to become insufficient to grow crops sufficiently. Also, war caused trade routes to change, and there were few safe trade routes. Less trade routes, and less crops caused starvation. This caused the Maya civilization to fall, and the people who did not die from hunger moved out of the Maya cities to different locations. This is not the case for all Maya cities. Some Maya cities were not very close to a water source which made life very difficult during the drought. Scientists believe that there was a drought for about 150 years in Mesoamerica. Therefore, the cities that weren't very close to water died from dehydration (lack of water). Some cities such as Palanque fought a lot with other cities. This may have caused there demise. 


      The Mayans may have believed that there wasn't going to be a meteor strike in the cities for all we know. They did have a very complicated calendar, and a priest may have misinterpreted the calendar and said that the world was going to end or there was going to be a forest fire. We don't know for sure, but archaeologists are working on figuring this puzzle out.
