Do you know who started the Columbian Exchange? As you might have guessed from the name of this blog, the Columbian Exchange was started by none other than Christopher Columbus. He started it when he first set foot in the Americas. After that, a whole new trade system started between the Americas and Europe. There are many positive effects of the Columbian Exchange. One is that whole new foods were traded with the Americas. Food like cacao beans and different meats were traded. Another one is that we got the new land for ourselves.

There were some negative effects of the Columbian Exchange. One of them is that disease was brought over by the Europeans to the Americas. This caused the fall of the Incas and Aztecs and Mayas. Another bad effect of the Columbian Exchange is that we destroyed some great civilizations. When the Europeans came, they took all the stuff from the civilizations and left them in ruins. There was nothing left after that. During the Columbian Exchange, the Age of Exploration was happening at the same time.
 
Hey guys I'm back talking about zoo day and today I'm talking about my favorite station there. Most of the stations were really boring, and I didn't like it. The one I enjoyed the most and the one that was the best was Mr.Brown's station. His station was about a kangaroo and how far it could jump. We had to calculate how far we jumped and see if we could jump as far as a kangaroo. I didn't jump that far and only jumped like 2.1 meters. I saw Mr.Brown jump, and he jumped like 3.8 meters which was pretty amazing.

This was the only station I like because it was fun and not to boring, but also educational. All the other stations didn't stand out for me because they were kind of boring and not fun. To make the stations better at zoo day, they should have stations that are fun, but also educational. Maybe they shouldn't have any stations at all and just have like a zoo guide tell us about the animals and give us activities to do. I hope next year the zoo is fun for the new seventh graders and also educational for them to learn about the animal they got.
 
In the  core, we have been learning about ancient civilizations in the Americas. We learned that the fall of the Aztecs was similar to the fall of the Incas. First of all, both of these civilizations were conquered by Spaniards. The Aztecs was conquered by a group of Spaniards led by Hernan Cortes. Cortes conquered the Aztecs by killing the leader and stealing their gold. The Inca empire was conquered by a man named Fransisco Pizarro. Pizarro conquered the Incas by killing the leader and stealing their jewels 

Another way they were similar was the Spaniards brought new disease to the empires. When the Spaniards came to conquer the Aztecs, they had a ton of diseases that spread very quickly. It killed most of the Aztecs which lead to their fall. The Spaniards who came to conquer the Incas also had diseases that spread very quickly. It also killed most of the Incas which lead to their fall. Both Spaniards wanted to steal all their gold to bring back. 
 
This year at Computech has been one of the most funnest years ever. I have had a lot of good memories at Computech. There is so much I don't even know which one to right about. One of my best memories at Computech was joining the Science Bowl team. I had so much fun joining Science Bowl. When we had our competition, I had so much fun. Even thought we didn't make it to Washington D.C., it was still so much fun.

Another favorite moment at Computech was meeting my teachers. I was afraid of meeting my teachers at Computech because I thought they would be strict and mean. When I got to meet them, the were really friendly and really nice. My favorite teacher at Computech is Mrs.Kanzler. Mrs.Kanzler is the nicest teacher and the funniest teacher at Computech. She makes me laugh and that is why she is my favorite teacher at 
 
There are many theories as to why the Maya civilization collapsed. Some say it was because of warfare, overpopulation, and even an over demanding ruler. I believe the Maya civilization collapsed because of warfare. There were many wars in their civilization and couldn't stop fighting. That is why they didn't have and emperor to rule all of the Maya culture.

The were bloody fights all over the empire. Due to this constant fighting, people couldn't grow crops and couldn't do anything. The crops died out and no people had any food to grow, which led to the end of the Maya civilization. Of course, this is only a theory. It hasn't been proven by anyone. Other people say it was because they had an overdemanding ruler. Others say it was due to many people living in the Mayas. Many people ate many crops, and there was not enough for everybody.
