Buoyancy

buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. 

Intro

My name is Mary and i'm a senior. I'm really cool and outgoing. I love owls, and jellyfish. I stay after school almost everyday to practice with the band, because I am in color guard. It's fun, but difficult and tiring. 
I plan to graduate with really good grades, and get into a good college. I don't really want to stay here for college as well, so I will be working very hard. I plan, to become a history teacher, in high school can't deal with little kids, in middle school or elementary.
