POWER

What is power? We all think power is like grown ups telling us what to do and lights and stuff like that.  We also think power is like Superman, Batman, and Spiderman.  Well not this kind of power.  Power is how quickly work is done.  Power, work, and force are all in the same category.  Force is measured in newtons, work is measured in joules, and power is just work divided by the time.  The way you write the formula for power is P=W/T.  To find how much power you used you have to know how much work you did and how long it took you to do it.  If you were lifting something that had a mass of 10 kilograms and you lifted it 10 meters in 5 seconds then you did a lot of power.  The faster you do work the more power you have done.  So if you lifted something that was 5 kilograms, 5 meters in front of you and you did it in 5 seconds then you didn't do that much work.       

The trip to Florida

The trip to Florida was good.  We saw the shuttle but we couldn't see it launch because they kept changing the days.  We left Monday night at around 9:40. For the first few hours on the bus we all talked and watched a movie.  At about 12:00am we all fell asleep and it was cold on the bus.  When we got to the retreat we had to sit on the bus for a few minutes so the teacher could check us in.  Everyone was tired because when we got there it was 6:00 in the morning.  We got to our rooms, put our bags down, and then we got back on the bus and went to the Kennedy Space Center.  We first went on the tour and saw the shuttle from a far distance. You had to squint your eyes to see it.  We also saw this big machine that moves the shuttle up and down.  It weighed 6 million pounds! When we got off the bus we watched a movie talking about the launch and how it happens.  When the movie was over we went through the exhibit and there was this thing that showed us what happens to the shuttle and what they need to do to it. We saw all this cool stuff and when we all went to the Imax movie everyone fell asleep and didn't really see anything even some of the teachers fell asleep.  After that was over we went on this simulator and before you go in you have to watch a move and it tells you all you need to no about the shuttle.  When you get on the guy that talked to you about how all stuff works tells you how the simulator works and what you need to know.  It goes up, down, back, and forward and also when you get in to space your gravity turns off and you open the top hatch and see the earth.  Then when you get off you walk down the hallway and theirs all these boards you can read to lean more about the shuttle.  No one had time to look at them because of all the other people that were walking behind us.  Once that was done we went to the gift shop and everything there was so expensive.  The chess board that I wanted was $40 and that was the only thing that I really wanted.  Me and Fatima were standing in line for 2 hours and I told her that we stood in line for to long not to get the chess set.  When we left the store everyone was waiting and then someone told us that they postponed the shuttle launch until the next day.  We were all mad that we had to wait another day to watch it.  The next day they postponed it until Thursday and that's the day that we were leaving.  We were gonna stay and watch but when we woke up the next day they postponed it again until Friday and there was no way that we could watch it.  After that we went to the beach and I didn't like water so Fatima and Celine said that Poseidon was mad at me cause I said that.  He got my shoes wet and that mad me hate water even more.  We stayed at the beach for a while and then went back on the bus and back to the motel.  The next day we left and we were all still kind of mad that we didn't see the shuttle launch.  The drive didn't seem that long the way back but of course I fell asleep listing to music.  Then we stoped at McDonald's and kind of had a second breakfast.  We all ate on the bus and then went back to heading home.  Once it was like 3 or 4 we stoped at Wendy's for lunch.  We ate again and then stoped one more time to go to the restroom.  That was our last stop until we got back to the school.  I got my stuff and left because my parents were already there so I just went right home.
