Electricity on Mars
Electricity is a form of energy. Electricity is the flow of electrons. The negative charge of an electron is equal to the positive charge of protons, and the number of electrons in an atom are usual the same as the number of protons. When the balancing force between protons and electrons is upset by a force, an atom may gain or lose an electron. When electrons are lost from an atom, the free movement of these electrons creates electric currents. Static electricity is when electrical charges build up on the surface of a material. It is usually caused by rubbing materials together. The creation of this build-up of static electricity is that objects may be attracted to each other or may even cause a spark to jump from one to the other. Current is the rate of flow of electrons. Unlike static electricity, current electricity must flow through a conductor, usually copper wire. Current with electricity is just like current when you think of a river. The river flows from one spot to another, like how electricity flows through a circuit. Discharge is a type of energy that is not controlled. an example wood be lighting. How the flash of light is not organized and straight, the flow of the electricity is jagged.

If I was going on a trip to Mars I would need electricity for many things. The main thing would probably be for things I need in my space ship. The first thing I would use electricity for would be a way to communication, control panel, sensors, computers, and the engine. I would also need electricity in my space ship for lights. These would help me see the buttons and everything in my spaceship. Electricity would be useful to heat and cool my space ship. Also for food resources like a refrigerator, microwave. and an electric stove. If I would land on mars I would need a radio, a thing that scans for life with, a rover,and a lap top to control the rover. You can see that there are many things that I can use electricity for on the planet Mar

Magnetism on Mars
Magnetism is the attraction and repulsion among two objects. In magnets there are north and south poles, which are used to attract and repel other magnets or objects. The Earth has a north and south pole like a magnet, and which is used for compasses. The earths north pole is wear the needle on a compass is always attracted to, which means that the needle's south pole is always pointing to the north because opposites attract. Magnetism is also used everyday things like when you drive. When you car pulls up towards a light, magnets in the ground send a signal to the light witch helps figure out when to change the light. There are also only three metals that are magnetic; iron, cobalt, and nickel. These three metals have a north and south pole like a magnet. which are the strongest parts of the magnet. when a magnet is brought towards the metal the atoms in the metal line up and the metals turn into mini magnets.

 Magnetism can be used to search for life on Mars. Magnetism can be used to separate the different pieces of the rocket using electromagnets so the electricity could be turned of to relies the separate parts. Magnetism can be used for a navigation on mars because Mars also has a Magnetic poles. Magnetism can also be used to keep tools in one place during flight in a spaceship because there is no gravity so things would float and you cant use the m when they are floating in the air. The tools could be made out of iron and stuck to magnetic walls. Magnetism is used in many different ways on mars, including for rovers, spaceships, and also finding life.

From Big Bang to Galaxies
In the big bang our universe exploded from out of nothing 15 billion years ago. It exploded from the size of an atom to the size of the earth. When the galaxies where first created there was matter and antimatter. When these two matters combine they create energy. That can also reverse and the energy can create matter and antimatter. In the universe there is more matter than antimatter so this is good for us because the matter makes planets and the stars. Our galaxy was formed 3 billion years after the big bang. When our universe was first formed there was radiant energy and also exotic molecules which where quarks and anti quarks.

The Milky Way Galaxy
The Milky Way Galaxy has disks made of gas and stars. Our sun is in the disk of the milky way galaxy. Our sun is half way out from the galactic center in the disk around the galaxy. A dwarf galaxy is mixing with the milky way Galaxy surrounded by the corona. The galactic center has red and orange stars that are the older stars of the galaxy. The n ucleus of the galaxy is a black hole surrounded by clumpy ring of gas clouds and a disk of dusk. Our sun takes 250 million years to go around our planet.

Lives of the Stars
Stars form in cold dark clouds of dust. Disturbance in the gas causes cores and each core contracts when gravity pulls it together. There are things called protester that forms by being surrounded in clear gas. The most massive stars are bluish white and forty more times than the sun and shine brighter. Our sun is the forth biggest star out of all the sizes. If the lower the mass smaller and dimer, and different color the star will be. 5 billion years ago our sun formed and it gets larger and become brighter after very long periods of time. The sun will become unstable It will shrink and finally become a dwarf star after a very large period of time.

The Sun
In the star our sun is a sun. It is our star because it is much closer than all the rest of the stars. Our sun is a ball of hot gas that gives of energy. During the eclipse of our sun is corona covering over the sun. During the eclipse the outer parts of the sun is covered, but the core is not. The core is the strongest part of the sun. In the core of the sun, hydrogen is sacrificed to create energy. This energy creates solar flares that blast hot particles at the earth. The earths magnetic field blocks the solar flares. The sun also has a magnetic field that is 5 times stronger than the earths magnetic field.

History of the Solar System
The solar system first started by solid materials starting to collect into larger and larger clumps known as plantitesimals. They collided and stuck together or explode. Then the giant planets grew and they had their own rings that had moons and kept gas in the atmosphere. After that the four terrestrial planets formed. They were bombarded with rock and the core was very hot and radio active material. The moons was probably another planet that collided with earth and got stuck in its gravitational pull. The earth gained its atmosphere later on after other planets because of the gasses from the volcanoes on earth.

Rocket History
The first device to successfully employ the principles essential to rocket flight was a rocket-like device called an aeolipile. The Chinese also began experimenting with rockets. Which where gunpowder filled tubes, and eventually added them to arrows. this showed them that the "fire works" could launch because escaping gas from the bottom. After this discovery there was a war the Chinese verse the mongols, they used rockets on there long roods. These where used as weapons of mass destruction. In the 20th century many different rocket development groups popped up around the world. These different groups developed rockets around Germany, US, Soviet union, and England and many other countries. The development of these rockets where used for war and not for a launch to the moon. The first satellite orbit was on October 4 1917, by the Soviet union. Later on after the satellite launch of the Soviet, Made the US launch a satellite and later on create there own formally organized space program called NASA.

Since the beginning days of discovery and experimentation of rockets have evolved. From gunpowder arrows to simple machines. Also rockets of weaponry and also finally rockets to try to move people to the moon. Throughout time humans have developed ways to try to go throughout the universe and travel, and one of there main ways of travel was through the development of rockets. These rockets that where developed where used for exploration by humankind.

Rocket Experiment
The purpose of this experiment was to see if the mass of a rocket affects the height the rocket will fly. The rockets with the larger mass did not fly as high like I thought in my hypothesis. We first made our rockets witch ours was called Merica 1. We assembled our rocket with all the different parts of a rocket and then went out side to launch. There where a group of two people who went 100 yards away and measured the angels.

After we finished building our rockets, launching our rockets and also measuring angels. We used trigonometry to find how high our rockets went in the air. We had to plug in the tangent of the angel times the 100 yards we went away from the rocket, and this brought us how high our rockets flew. My rocket flew 76.7 meters in the air with a angel measurement of 37.5 degrees. Also that our rocket was on of the middle masses of the group. Which shows me that the less mass the higher it will fly and the higher the mass the less height you rocket will get at its Apogee. Luckily there was only one rocket that had its recovery system not work, witch was actually really funny because it went up and came straight back down. Unlike all the others that floated back to the ground safely, but I wouldn't say on the ground because our rocket got stuck on the batting cage. =Wiki intro 6=

Mars Rover Drop
A couple days ago we designed our robots. My group decided to make a bed kind of thing for the egg to stay stable in. We used a cup surrounded by rapping paper to act as the bed for the egg to stay in. after this was created we used paper towels and other materials to create a cousin for the egg so it lands softly. after this we found that by putting a piece of paper on the bottom of our capsule where the egg was sitting in it put more air resistance and made the rover fall slower. Even thought the rover fell slower it did not slow down enough so we put a parachute made of two sheets of paper on our capsule, holding the rover (egg).The next day when we dropped the rover our capsule flipped over and did not make it. It landed on the wrong side where there was hardly any cushion. Our rover (egg) broke and did land safely. We found that if our rover did not land right it would easily break because we di not put any protection on. Also we got it to land on the tennis court and we got the egg out in the time limit. The thing that went wrong was the dropper did not land on the correct side, so our egg broke. We should improve our parachute and add more cushion.

Robot history
Robots are a very complex machine that are capable to carry out an action. These machines have been developed and throughout time. The first robots that where developed where used to make work easier. Like how the world’s first moving conveyor belt-based assembly line with robot arms in a car factory. A car was able to be assembled in 93 minutes. Also the first robot toy was developed in japan 1932. It was called a Lilliput and it was a wind up toy made from tin witch walked. It was focused to be used as child entertainment. From this toy it started a new area of toys in the future. Know we have animals that are robotic and make sounds and also move. These developments from the history have brought great development in robots.

Throughout time Robots have been used as entertainment, help in work and have been used to help needs of humans. These robots have done tasks that would have taken a human a very long time or a human would have died trying. Like in 1994 Carnegie Universities eight-legged walking robot, Dante ll successfully descends into Mt Spur to collect volcanic gas samples. If this robot was not created there would never be any samples from Mt Spur because if a human treid to go in and collect samples from a volcano, they would shrill up and die in the volcano . =Wiki Entry Eight=

NXT Robots
There are many different things that robots can do, including moving. They use motors that are programmed to move the robot. These motors can be used to drive forward, backward, point turn left, point turn right. Also it can just turn right, and also left. These motors are also used to drive in squares and drive through courses.There was challenges that we had to move through with our robot. The first two where simple courses that we had to drive through, and the third one was a driving course where we had to knock ball into a bin. We did this by driving to the ball accelerating and knocking it in and then backing up. Some times there where challenges with our robot like when it doesn't turn how we want it or we have to guess how far the robot was going to challenge.

On robots there are not only just motors to make it move, there is also sensors. Sensors are things that can detect different senses like our body's. We first used a sound sensor that detects sounds to do different movements. Second we used the ultra sonic sensor witch detects how far something is away and if it gets to close you can make it move or turn. The third sensor is the light sensor witch is used to detect the brightness things. The fourth sensor is the touch and when it touches something it turns or moves. These sensors can be used to help robots move through courses. =Wiki entry 9:=

Geology on mars
There are many ways that geologist determine what mineral or rock something is. Including streak that you see in the picture. Also there is hardness, color, luster, magnetism, and many more. It is hard finding what rock or mineral these things are so geologist usually use 7 8 9 maybe even more to as precise as they can. One test the streak test is performed by rubbing a rock on a white and black slab to see the actual color of the rock. Also there is the hardness test where you scratch a rock or mineral with other materials to see how hard it is. You can also see if the rock reflects lite by taking a UV light and shining it over a rock or a couple. These are many ways that geologist find out what rocks are what. Hopefully you can find some out on your own. Curiosity is a astonishing robot. What it is doing mars is amazing and I did not think we had that technology yet. It is doing every
