Today in class we went over the homework, which was if your mom is making pizza down stairs and you are on the second floor, why can you smell the pizza. You can smell the pizza because the pizza particals are moving freely and up to the stair and into your room. But your brother next door to you can't smell it. This can be because his door is shut and the particals can't get into the room and he can't smell it.
Then, we did an experiment, Mr. Finley put some sort of smelling alcohol on a chair and had about 10 people stand around it. We said that the people in the front would smell it first and the people in the back would smell it last. The first two people to smell it were katie and i. then TJ and Anderson, then it went around the circle. Not everyone smelled it at the same time, and the particals moved at all different speeds. So they may have reached one person before they got to another person. In the end everyone smelled it except for connor. Particals move in random directions, they move at random speeds, and they move in all directions. When particals get light shun on them they get something like and energy boost and they speed up and go off in random directions.
