Weather Fronts

There are four different kinds of fronts. Cold fronts are one of them. When there is a cold front the cold air goes under the warm air causing the warm air to rise. That makes it colder instead of warmer. Another kind of front is a warm front. What happens when there is a warm front is the warm air pushes the cold air out of the way causing the warm air to take its place and makes it warmer. Another kind of front is a stationary front. During a stationary front warm air and cold air mix causing thunder storms. The last type of front is a occluded front. When there is an occluded front there is a warm air mass caught between two cold air masses. The weather near the ground becomes cooler and water vapors condense and the weather may become cloudy rainy or snowy. Those are the four kinds of weather fronts.

Atmospheric Factors Affecting Climate

Acid Rain

Have you ever heard of Acid Rain? Well acid rain is very harmful to us humans and plants and animals. Acid Rain contains more acid then normal rain. Acid Rain is formed by the burning of a lot of sulfur,which produces sulfur oxides. Acid rain is very strong. It is so strong it can damage the surfaces of buildings and statues. Acid Rain harms ponds and lakes which is harmful to plants, amphibians, fish and insects so they can no longer survive. Some actions that humans can take to prevent Acid Rain are not burning so much coal so that there is not as much sulfur oxides in the air. That is what Acid Rain is, does and how you can prevent Acid Rain.

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.

Enigma Box

The skills that scientists use are inferring, predicting, making models, classifying, and observing. I used most of these skills when observing the Enigma Box. I used predicting when I had to try to figure out how the Enigma box worked and why it worked that way. I had to make a model when i had to draw a picture of the inside of the Enigma box. Last I had to observing when we had to look at the Enigma box and guess what it was.
This is what I think the Emigma box looks like. Well the Enigma box is a black rectangle that is hollow and has a tube running through it. The tube allows the water to go out of the bottom. The Emigma box box is hard also. Well the water only comes out the tube whan it is filled with 450 millaliters of some type of liquid. THe tube that is the center of the box actually comes out of the very bottom of the side of the box. You can also make a hand made Enigma box and for it to be able to come out you have to fill it with at least 1000 millaliters of water.
Humm. I wonder how the Enigma box works. Well I think there is a sensor inside of there. I think it can tell when there is 450 millaliters of water in the tube and there is something covering the end and when the sensor goes of the thing opens and lets all of the liquidf out that is in the tube. That is why the water does not come out at 450 millaliters and then 320 the next time so the sensor is consistant.That is how I think the Enigma box and the tube works.
I was wrong about how I thought the Enigma box worked. The way the the Enigma box really works is the tube is tied and when the pressure gets high enough then the water is allowed to come out. There also is an overflow line called the overflow line and if the liquid gets over that then the water starts to overflow and come out of the box.
