In Social Studies this year we learned a lot of things like Panama and the Canal. One of the favorite things that I learned this year is The Reconstruction Era. In that lesson, we learned that The Reconstruction era was the period after the American Civil War from 1865 to 1877 and the purpose of the Reconstruction was to help the South become a part of the Union again. My favorite lesson that we learned was How American Indians Viewed Their Environment. That was my favorite lesson because we learned that the natives believed that each part of nature had its own spirit and each person had to maintain a balance with these spirits. In conclusion.

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
