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.

Energy Energy and more Energy

What is energy? Anyone know? Anyone at all?  Well energy is something like work.(you remember that blog right)  Energy is the ability to do work but not work it self.  The two things you need to know about energy is potential and kinetic energy.  Potential energy is like when if someone is about to throw a ball and they are going to put all there strength into throwing it.  So Potential energy is something or someone that is about to do something to that object.  Next is kinetic energy,this is when a person or thing has done some kind of work to that object.  An example of kinetic energy is if someone throws a ball, the ball has lost its potential energy because the person let the ball go.  The ball now has kinetic energy because of its motion.  

Which do you think has the most potential energy, a glass on the floor, a glass on top of the frig, or a glass on a coffee table?  The answer is the glass on top of the frig because the higher the object is the more potential energy it could have.  The higher object does have more kinetic energy then the lower glasses.  

NO JUSTIN BIEBER

Justin Bieber started maybe like one or two years ago.  Usher was his mentor and I think that Justin just needs to go away and go to school like every other sixteen year old boy.  All these girls are in love with him and he just makes all these new songs.  He was on some show and the guy asked him if he thinks Germany would be good in basketball.  He said he didn't know what that was.  So the guy shows him the card and he still doesn't know what Germany is.  I think that if he wasn't doing all this singing and had went to school like everyone else, he would know what Germany is. 



He was singing on stage one time and someone threw something at him and it took him like 2 minutes to react.  See what not going to school does to you.  My guess is people would just keep liking him until something happens.  Something always happens and the media turns it around and makes them seem like there the bad guy.  I'm surprised that he hasn't already been disliked but I'm not surprised if Germany doesn't like him anymore.  If Justin Beiber was gone off the face of the planet right now then there would be riots and chaos everywhere, but if people wait and he gets older then they would stop liking him.  Me personally I don't like him but I'm probably one out of like 20 people on earth who hate or strongly dislike him.
    

WHO WANTS TO DO SOME WORK!

What is work? Everyone knows what work is right?  Well not this kind of work.  Work is done when a force causes an object to move in the same direction of that force.  There are different types of work and even a way to measure it.  Effort is when you can be doing so much and trying so hard to do something but you still might not always be doing work.  You can be putting effort into moving boxes from place to place.  However once you started moving forward with the box the force was still moving up and the motion was going forward.  Remember about what newtons measure in, well work also measure in Joules. 

To understand how to find out if your doing work is to use the formula- W=FD which is work= force times the distance.When you find your answer you have found out what the Joule(s) of that object is. Well what's a Joule you ask?  A Joule measures how much work you have done.  If I were to push a box in a direction, then that would be work because I'm the force pushing on that box and were going in the same direction.(or positive work)  If I was pushing the box and using force and the box wasn't moving then you would not be doing work.(or negative work)  For you to be doing work you and the box has to be moving in the same direction.  Thanks for reading, now I've got my own work to do. 

ARCHIMEDES PRINCIPLE

Archimedes was not just a mathematician, he was also an inventor, and a engineer.  He was born in  Syracuse,Sicily and lived in the year 250 B.C ( about 2,260 years ago).  One day a craftsman made a crown for the king and Archimedes didn't think that the crown was real.  Archimedes used what he called  Archimedes Principle and found the density of the metal in the crown.  He also found out that when you put something in the water the water would rise or displace, this is called displacement.  When he got in the bath he found out that his body was lighter in the water and he jumped out of his bath running and yelling Eureka ( Which is the Greek word for "I have found it").  

He also created great things in his life which some of us like today.  Archimedes created what he called "Block and Tackle" which meant that he could move things without having any trouble.  He created the screw pump which meant he could move water from a low place to a high place without trouble also.   Archimedes used what he called the sand reckoner and he used that to calculate the number of grains of sand there were in the world (kinda weird right).  He invented war machines to help protect his city and he thought that his inventions were the best inventions every created.

Buoyancy and Density, Good or Bad?

An object will sink or float by its density and buoyancy.  If an object can float then the buoyancy of that object is positive.  If the object sinks then buoyancy is negative, and if the object neither sinks or floats then it's neutral.  If you were on a ship you would need to know the buoyancy of the water so you dont sink or go to slow.  If you compare a lake and rock the molecules in the rock are closer together than in the lake so the rock would sink.  To find an objects density you divide the objects mass by the volume.  Density is the physical property of matter and is in everything.  If I was in the pool I would just be standing there with some of my body in the water, but if I was less dense I would float and not ever be able to swim ( bad I know).  When you push a liquid away thats called displacement.  The dead sea has a lot of salt and because of the salt we can float without trying and we can also eat it.

Gravity is the thing that pulls all of us to the earth.  If I were to jump I would fall right back down because of gravity.  Also, when I push people ( Lizzy, Azaira) on the swings outside they go up becausee of force and come back down because of gravity.  To me I sometimes say we don't need gravity and we would be better off without it.  We could do anything and life would much easier.  If we didn't have gravity then the earth would not orbit the sun. Then life on earth would be different.  

 A few weeks ago Tyler walked in front of Shelby while she was swing and he said "Hit me with your best shot" then Shelby couldnt stop herself so she hit Tyler and he went flying.  Gravity pulled him down towards the center of the earth.
