Earths Atmosphere

The Earths atmosphere is different from the moons and other planets in many ways. First off a planet with no atmosphere is not suitable for living things and earths atmosphere is. There might not be enough nitrogen for a person and we need nitrogen to be able to live. The moon is not suitable for us because there might not be all of the gases for us to live and we would not be used to it so more then likely we would die . The other way earths atmosphere differs from other planets or the moon is the temperature is does not stay in if there is no atmosphere, and since the earth does have an atmosphere the temperature does stay in. That is how Earths atmosphere is different from a planet that has no atmosphere or then the moons atmosphere.

Space Exploration

Science Exploration

The Science of Rockets
NASA. has three types of rockets. One is called Atlas, it uses solid fuel boosters and liquid fuel engines to launch into space. The second one Centaur uses liquid fuel engine to maneuver into proper orbit.

The Space Program
NASA is used to explore space. There was a space mission called Apollo 13 that NASA thought would do very well in space. What really happened was the oxygen tank like blew up and they had to go back down to earth.

Exploring Space Today
Today we have planned to use small robots called personal satellite assistant. The personal assistant floats next to the an astronaut and can move in various directions. It can also alert the astronauts . Some technology it has are a camera, light and video phone used for communication.

Using Space Science on Earth
NASA only gets one percent of the governments money Many people think that they should not get any of the governments money. Now NASA points out basic knowledge about the universe that is gained through space exploration that gives us a better understanding of the earth.

Reason for Seasons

After doing this gizmo on seasons I have figured out some reasons that there are seasons. THe main factor that causes seasons is tilt of the earth. The earth has a thing called an axis that it sits on. The tilt effects the seasons because when the earth rotates there are more heat rays hiting the earth because the earth has a tilt. When the earth is higher above us there is more solar intensity. So when it is December 21 there is not as much solar intensity then there is lets say on June 21 or March 21. Now you know some of the raesons for seasons.

Zoom and Prespestive

Zoom is a book written by Istvan Banhyai. The book started with a really closer picture of a roosters head, and by the end of the book they were very far away from the earth so you could barley see the earth. During this book I made many inferences and not all of them were correct. I made some that really close and some that were not so close, but I never hit it right on the dot. If you are wondering an inference is trying to figure out why someone or something is the way it is. That is almost everything about the book Zoom.

Have you ever wondered what the word perspective means. Well it means the way someone looks at something. Has there ever been a time where you thought you saw something and then you change your perspective and it is not at all what you thought it was. Well that has happened to me many times before. Like once I saw this thing far away and I really thought that it was a human and then I moved to the I would angle and it turned out to be a statue. I was like wow that can not be right so I moved closer and sure enough it was a statue. That is what perspective is.

Scientists gather a lot of very important information everyday. Like an example is if they look at something and it turns out to be important then they might get a lot of money. Like lets say the first person to discover space he probably became pretty rich. So when you look at something you might want to write it down. That is how scientists gather information with perspective.
