Dear president,
I would like to state how important it is that we improve are energy. I think we sould use windmills for our energy. Windmills creat energy by the wind pushing on it and the proplers spinning. There are so many ways that we could use it. You could put some on the coast of Lake the great lakes or near oceans, because theres lot of blowing air coming off there. They are some what expensive to setup but they are the cheapest to keep running. We can place the windmills on land that is to hard to place house or a city there. last year the windmills made 12% of the usa energy. If we keep placing these windmills all over the usa we can rise the energy saving
Some people would say "windmills if the wind is going to fast they are shut off but, it's new design of the windmills are getting better. they Less costly to build and to keep them running. Also they are lighter and easier to transport. And they take the shortest to set up, unlike the hydopower it takes forever to build a dam. Getting smaller and can generate more power to use. The windmill has been made much easier to build and to buy. They are still very expensive but help the economy and to make more energy that we need.
Finally, so that is why you should get more windmills for energy. Most are smaller but they are still really big. One blade is 49 meters long and that is the best and smallest of windmills. We need to look at other countries and learn and copy how they use wind energy. That's why you should pull the state and nations attention to this and what we can do with it.

How simple machines utilize mechanical advantage to transfer energy?

Rube Goldberg

Are you tired of carrying box every where. walk from your house to your car and then getting tired and dropping them. well we have the thing for you. You can use simple machines to make a more difficult task(s) into a more simpler one.
With these simple machines you can use the wheel and axel to make a cart to place the boxes in. Then the incline plane or a wedge to then push it into the pulley, after that to pull it into the car, and then to use a skew to hold in down and to keep it in place.
So listen to your muscles and use the simple and affordable simple machine. It has simple writen all over it.

Problem: How does the same ball accelerate down different angled ramps


Hypothesis: The steeper ramps will cause the ball to accelerate more than the less steep ones because in my experience of testing gravity the bigger the angle the farther it will go.

Materials: rubber ball, 75 centimeters long inclined plane, 2 timers, calculator or pencil and paper =)


Cv: Toy car, ramp, protractor, way car is released down ramp, friction of ramp.
Iv: angle of ramp
Dv: Rate of acceleration and the speed of the toy car.


Procedure:
Gather materials
Place mark 10 cm from the end of the ramp
Place ramp at a 25 degree angle
Place ball at the top of the ramp
Release the ball (without pushing it) as your partner starts the first timer
When the ball reaches the 10 cm mark start timer 2
When ball reaches bottom stop both timers
Record total time and 10 cm time
Repeat steps 3-9 two more times
Repeat steps 3-9 three more times with 35 degree angle
Repeat steps 2-9 three more times with 45 degree angle
Use the formula
Acceleration = (final velocity - initial velocity)/time
To find the acceleration of each trial
Use the formula
Distance/ time= speed
To find the speed of each trial
Clean up

My hypothesis was correct on that the heaviest ball won. The ball did go faster the higher angle the ramp was. balls like everything else are effected by gravity therefore they get pulled to the heaviest object around. When the ramp was at the lower angles gravity couldn't make the ball go as fast because of the ramp holding it up. When the ramp was at the steeper angle gravity was pulling on the ball the same way but with less to stop the car from falling.

Problem: What impact doesth surface have on how fast different sized balls can travel?

I think that the small ball on the smoth lane, will go farther than the bigger ball, because fiction and gravity will have more effect on it.

CV:the force of the push, the angle of the ramp
IV:The leagth the balls travels down the slope
DV:The surface of the ramp, the balls

materials-
2 differnt weighted balls
A lego ramp
flat legos
tape measure
marker

procedure-
Gather Materials
Grab the bumpy ramp and mark where you are set the ball up each time.
garb the heavy ball and put it on the ramp
give it a little push
measure how far it went
record data
do this 3 times
now the same thing but do it with the lighter ball
now do that again but put flat bricks to cover the bumpy spots.
finish data
cleanup

Problem: how does the law of inertia affect the physical world
Hypothesis: the bigger ball will go farther then the small ball,because the bigger ball has more mass than the small ball, so it will have more speed going down the ramp.
Cv: hit of force on ball, surface, inclined plane, and the angle and distance of inclined plane
Iv: Size of ball getting hit
Dv: Distance the hit ball goes
Materials: ruler, inclined plane, marker, A small and light ball, and A big ball that has some weight
Procedure:
Gather Materials
Place one end of the inclined plane on a flat smooth surface and raise the other end up ten centimeters
Place the marker or dot on the incline plane to show where the ball has to go.
Place one of the balls on the smooth flat surface at the dot or marker of the ramp so that it is always equal
Position the ruler so that the 0 is lined at the side
Record the distance that the bottom car rolled
Repeat steps 2-3 more times
Repeat steps for the other ball
Record new results
Clean up.

Observations:When the greater mass and bigger ball hit it went farther than the smaller, because of the ball's mass was greater.

Conclusion: The balls rolled different distances because the lighter ball didn't have as much force as the greater mass ball. This is proof that Newtons First Law is true since the balls had to have a different amount of force to move the same ball different distances. The large ball moved the ball the farthest because it had the most force and the lesser mass ball moved the car less because it did not have as much force. Some probles I had were that the ball did not go straight all the time so I used the tape measure that could curve and measure it that way.

Science

Experiment and explain How do newtonslaws of motion apply to the physical world.

It applies to the real world through a lot of things like cars, toys, people, and almost anything that is made of matter. So if a person is standing still and another guy comes and pushes you that's an unbalance and the person standing still is going to fall over. Many toys need an unbalanced force to get it to work like a bouncy ball it needs an unbalanced force to make it bounce. A car uses the power of the engine to make it go farward. A object at rest will stay at rest until gravite or an unbalansed comes and moves it.
The surface of the legos are bumpy which is more friction that the ball has to go down which makes the balln become more slow and might stop the ball in motion and the ball is going to take longer time to trave down the slope or gape to get where it has to go. But with the flat rapes and legos we can make the ball go farther and still have low to none Energy forcing the ball. It well slow down the ball but it well keep moving with all the flat legos. The gravitational pull well make the ball continue going down the ramp with the flat panals the ball will go super far.

Walking Tacos

Walking taco Walks to much, talking tacos talk to much, but the normal taco just sits there doing nothing. No talking, walking, singing, danceing, and running no it just sits there doing nothing. Welcome to the upgraded Taco the walking taco!!!

Explain what makes life significant for you???

For me the freedom of an American. That we have the technalogy today to help us and to save lives. Have cars and planes to take us where we want. Back then all there was was war to look to. To fight for land, food, or control. Kings and Queens were in charge. Anyone that tried to stand up to them they would be killed. Today we have indepence in the US, so you can speak out to your leaders and not be hurt in the making.

October Harvest

Just think walking on to that ship thinking will I ever come back, will I ever see my friends and family again? We send people over to fight for patriotism every day. We have fought for patriotism since the beginning of man to the declaration of independence to even today and will fight for it for Patriotism tomorrow. To begin with the Declaration of Independence was one of the great patriotism acts almost ever. It took several years to fight the years for fighting the British to fight for our independence. Just think signing the independence of a new country. After the war 56 people signed the Declaration of Independence to say we fought for our Patriotism, freedom, and speaking freely. After the war the US fought for the many different skin color we have in the US today. This war was called the Civil War. During the civil war the US was divided in to two to fight for the freedom of slavery. Even today we our fighting for the freedom of color, women, and even religion. Right now we are fighting to kill the man in charge of 911. You don’t have to be a soldier to help or believe patriotism. You can help other people, give money to support the army, or just be a helpful or nice person. You could be a nice person by cleaning up the trash and throw it away and not just throw your trash there. Without patriotism this world would be nothing like the world today. There would no freedom no rights and maybe even the technology we have today, because no one would share there creations to the world, so does patriotism matter?

A Day No Pigs Would Die

After reading “A Day No Pigs Would Die”, I was impressed of how the author was slowly giving you clues to the end of the story and why the story is called “A Day No Pigs Would Die”. Like when the dad said he had an infection, and when they were talking while they were watching the sunset. My reaction to the story was, wow I did not know that a person can become so mature and so responsible in so little time. Most kids if they found out there dad died they would cry.

The Clearing and A Secret for Two Introductions

Just think a new person builds a new house near your home. In this person yard you have a fort , where you play kick ball with your friend, or there is something special over there. You think the neighbor will be a nice and kind person, but when you take one step on to his lawn he comes out of the house and yells at you and says “get off my lawn”. You get scared and run back to your house like your life depended on it. In this paper you will learn that neighbors can be very helpful.



Just think you work at a job you like for your entire life, with your favorite animal. You’re been working at the job for about 30 years and nothing strange has happen, but one day you come to work and you find out that the animal you worked with at your job is dead, the animal that you were best friends with, have teach the animal cool teaches to, and have told all your secrets to. In this story you will find out what the main character did in this story.

The Circuit

Just imagine you work every day of your life just to stay alive it is like being on a horrible rollercoaster over and over again. Your job is to pick the crops that are in season and when the season ends you move to a new farm. In one day you make 15 dollars to feed 6 people in your family, spend money to make one of your kids go to school, and to pay for your home and you never get any days off. If you would compare your life to theirs, you would appreciate how much your life is better than back then.
In the story “The Circuit” the main character whose name was never said has to move again to a new farm. His family which speaks a different language moves from place to place to find a job to pick the crops and to except what any other job to afar, or to pick whatever is in season at the farm. When that crop or season is over, the family of six moves to a new farm, because they make their money off of the plants they pick. Every time they have to leave, he hates to go, but he knows that he has to leave just to make enough money to stay alive. Today we have other jobs instead of working in farms all day. After picking about a whole season, the second oldest boy finally started to go to school. The boy is the only one in his family that can go to school, because that is all his parents can afford. Today kids have to go to school and if your family or you can’t afford it, the government will usually pay for the child to go to school to get an education. He went to school every day and at lunch time he would stay with the teacher and learn how to speak better English. In current times you can go to a school that teaches you how to speak English or another language better. One day at lunch time the teacher ask if he had ever listened to music? He said “yes” but not too much. After that the teacher asked if he had ever played an instrument. And he said “no”, so the teacher started to teach him how to play the trumpet. In the present we have music classes to how to play an instrument. He was so happy that his teacher was teaching him music, and now he wanted to tell his parents very badly, but when he came home everything was all packed up and ready to be sent to a new place to start their lives all over again.
Look at how much better life is today. With some of the jobs today like computer jobs you can make a living without do any much physical work, but there are jobs out there you have to do some physical like builders. Today we have ways to make are life’s easy like computers and better technology, but with power comes more responsibly.

All Summer in a Day

Imagine yourself different than the people around, but also similar. Like being a flower, but with a lot brighter colors than the flowers around you, or being the first leaf to change colors and fall off the tree. Well in the short story “All Summer in a Day” by Ray Bradbury, the main character of the story was born on Earth and brought to Venus, while all the other children in class were born on Venus. Here you will that you might thick you’re different when you are really the same.
In the story the “All Summer in a Day” a girl named Margot that once lived on earth and was brought to Venus when she was just a child, while the other kids in her class were born on Venus. On Venus it never stops raining, except every 7 years it stops raining and the sun comes out for one hour. Today was the day they thought the sun would come out, Margot was so happy to hear that the beautiful sun would come out today. Margot say she remember the sun when she was a child, but all of the other children in her class think that she has never seen the sun and she is lying. People have been treating other people different all over time to religion to skin color and even today people are still being treated differently. They also think that the sun is not going to come out. Some of the kids in the class might be jealous because they have never seen the sun or can’t remember how the sun looks. In the class there is a boy named William, he hated Margot and how she all was talks about the sun and how bright and beautiful it is, so as soon as the teacher left he told all the kids to lock her in the closet. Right after the kids locked Margot into the closet it went silent, the rain had stopped! The kids went running out side without even remembering what they just did. They went running around like mad man like it was the happiest day of their life. Some people would if this was the first time ever seeing the sun. After about an hour running around the sun started to hide be hide the dark Clouds and then it started to rain. The children ran inside, just to remember they had left Margot in the lock. Some people would feel ashamed, treating someone different, because you’re jealous of them.
You are still human like everyone around you, no matter the color of your skin or where you can from. You might think you’re different, but you are the same.

The Stolen Day

Some individuals could relate to the events of the main character found in the story the Stolen Day. “Stolen Day” is story about a young boy that lies. Every person lies at least once in their life, to deceive, trick a person or to protect the person from pain or hurt.
“Stolen Day” is a story about a boy that trick to his teacher to get out of school. After getting out of school he went home and got his fishing pole, and then the boy went to the fishing pond. In this case the teacher would feel bad if the disease was real. Although the teachers don’t know, but if they did they would be very disappointed in him. Then after having his fishing pole in water for about two or three minutes he got a bite. He pulled and pulled till he got the fish on the shore. On the fishing line there was a huge carp almost the size of him on the line. When he brought the huge carp home his dad said that he had talked to his teacher today and he knew that he was in big trouble. He lied to his teacher to go fishing; he could of gone fishing after school at night that’s when the fish really bite. He should get in trouble he lied to his parents.
This is a story to teach people lying can hunt you but also other people. Lying is never a good thing to do. You should never lie to your friends and family, you always should say the truth. Whatever goes around comes around, so some people might lie to you.
