I learned many things this week, either from class or outside. There are some that are important, and there are also some that are normal, but I think the most interesting one is I learned how sound works in physics class.
      The weeks before we were trying to build a trebuchet by our own. Now we are finally back to the normal studying of knowledge, I am always interested in it. We are learning how sound travels now, sound travels by creating waves that can be transported by objects like air, wall, water... In vacuum, sound can't be heard because there is nothing it it including air. The speed of sound is about 331 meters per second, and it is much slower than the speed of light, which is the reason why we always see lightning first and hear thunder next.
      This is probably the most interesting thing I learned this week, there are many many other interesting things that we haven't found out yet. I hope our world will become more beautiful.

Spring Break

    Everyone likes break, the same as everybody, I just spent a joyful spring break at the western part of America. The top 10 are: 1. Delicious food 2. Universal Studio 3. Grand Canyon 4. Roller coaster 5. 4D movie 6. China town 7. Casino 8. Small games 9. Circus show 10. Airport

    At the beginning of the break we went to Los Angles, there is a fabulous China town there. It has all kinds of traditional Chinese food there, the one I liked the most is the one that has delicious spicy food. It's almost been a year since I last went back to China, so I was very excited and waited very impatiently. And after 5 hours of tired flying it made me more impatient about it. I visited some popular American restaurant too, the one I liked the most is called Ruth Chris's. My favorite food is steak and I ate a ribeye steak and it was juicy.
    The second one I liked through this trip is the Universal Studio, I learned all the movies from the 1900's to now, there was also parts where it tells us how those movies are made. There were some traditional and popular ones like the Jurassic Park and the Fast and the Furious. But my favorite one is the King Kong. We went on a tour bus and we experienced a fabulous fighting between a huge dinosaur and King Kong. After we put on 4D glasses the show began. I felt we are actually in the situation, our bus was also moving toward and back and sometimes leaning to one side. The dinosaur and King Kong are about twenty meters tall and ten meters wide. At that time I realized how ruthless it was on earth long time ago, they were more bloody than barbarians these days. Finally the show ended by we fell down into a cliff and it lasted about five minutes.
    I also visited many great places through the trip like the Grand Canyon, Las Vegas... But I am not going to talk about it anymore because these two were my favorites. I hope you also had a wonderful spring break.
