What Front Did We Have This Week?

The front we had this week was a cold front. I know this because, the weather came in quite quickly. Also, that the results of the front was snow and cloudy sky's. Last, there was a lot of wind, and that is also a factor of a cold front.

Occluded Fronts

An occluded front is when a body of warm air is caught between two cold air masses. The two cool fronts catch the warm air mass in the middle and they mix. Because cold air is denser than warm air, the warm air rises over the cool air. They call it occluded because the warm air mass is cut off. The result of this front is usually cloudy conditions with rain or snow.

Stationary Fronts

Stationary fronts are when both warm and cold fronts collide but don't have enough force to move one another. With both having water vapor, they form clouds, fog, rain, and some snow. A stationary front can last several days.

Warm Fronts

Warm fronts are when slow moving warm fronts collide with slow moving cold air fronts. The warm air rises over the cool air. Warm air fronts usually come with storms, clouds, and rain.

Cold Fronts

A cold front is when fast moving cold air collides into slow moving warm air. When the two collide the warm air rises and the cool air takes control. Because of these cool fronts cumulonimbus clouds and cumulus clouds form. If the warm front has a lot of water vapor that will cause heavy rain or snow to fall. If not, the sky ill only be cloudy.

Atmospheric Factors Affecting Climate

Click the bold words (Atmospheric Factors Affecting Climate) above.

O-Zone

There are many ways o-zone can help us and also hurt us.O-zone is a molecule with 3 oxygen atoms instead of the average 2. O-zone helps us because these o-zone molecules absorb harmful UV rays. These UV rays are short electromagnetic waves from the sun that causes to inflict sunburn on our skin. O-zone hurts us because the o-zone molecules in our atmosphere are breaking down and and we are losing much our protection from UV rays. O-zone depletion is very dangerous. There is a chemical in the atmosphere called chlorofluorocarbons (CFC's for short). When UV rays come in contact with the CFC's a chlorine atom breaks off the CFC and combines with o-zone molecules, knocking off one of the oxygen atoms of the o-zone molecule. This happens throughout the atmosphere. This process is called o-zone depletion. This process hurts us because with less o-zone molecules protecting us from the UV rays there is most likely to be more of a chance for our skin to be inflicted by the heat and cause a bad sunburn. In conclusion, those are some of the ways o-zone can help us and hurt us.

London-Type Smog

London-Type Smog is caused by coal smoke. The term "smog" is when smoke and fog are combined. London-Type Smog is formed when fragments of coal smoke combine with humid air containing droplets of water. In London, England, most houses were warmed by coal. This factor caused the coal smoke to flea into the air. From the cause of London-Type Smog people in London began to burn less coal. Burning coal is the main cause of this issue. The consequences of London-Type Smog is air pollution causing sickness.

Earth's Atmosphere

There are many ways the earths atmosphere helps the planets survival differing from planets with no atmosphere. Earths atmosphere acts like a shield when a meteor is aimed toward earths surface. The atmosphere helps it because when the meteor comes in contact with the earths atmosphere the friction against that meteor causes the meteor to overheat and burst into flames, causing the meteor to disintegrate. Unlike other planets or moons that don't have an atmosphere, any meteor aimed at that planet or moon will come in contact with the surface. From the cause of the impact the meteor becomes a meteoroid. In conclusion, those are the differences and benefits that earth has that other planets don't.

Space Exploration

Science Exploration Summaries

THE SCIENCE OF ROCKETS

Since the 1950's NASA had been using atlas rockets in order to launch probes into space. Recent models of these rockets are approximately 58 meters high (174 feet). They are made of 3 Stages; Atlas (1ST stage), Centaur (2ND stage), and Payload (3RD stage). Atlas, uses both liquid fuel engines and solid fuel engines to launch the payload stage into space. Centaur, uses the liquid fuel engines to move into orbit. Payload, is the satellite or probe carried by the rocket.

THE SPACE PROGRAM

(History of NASA)
NASA (National Aeronautics and Space Administration) begun in 1958. The purpose of this program was to explore space. That meant that humans must fly into space. So NASA began Project Mercury. So they sent humans into space to find out if humans could survive. After Project Mercury was found successful they came up with Project Gemini. They learned about living and working in space. In 1969, was Project Apollo, putting men on the moon. Afterwards, became Shuttle Programs.
(Apollo 13)
Launched on April 11, 1970, Apollo 13 seemed like a smooth flight. As the mission progressed the mission became dangerous and life threatening. One of the oxygen tanks had blown up. As all Apollo Projects, Apollo had a three-passenger Command Module (CM) and a two-passenger Lunar Module (LM). The CM's supply of light, electricity, and water was lost. Mission Control on Earth used the LM to pilot the CM around the moon and back into Earth, landing in the Pacific Ocean. All astronauts lived, losing 15kg of dehydration.
(Going Back to the Moon)
Since the Apollo mission there have been 3 spacecrafts that have visited the moon (after 1972), and all participants have survived. In 1990 and 1992 on its way to Jupiter, the Galileo probe to photographs of the lunar North pole. These photos gave more information to earth about the surface of the moon.

EXPLORING SPACE TODAY

The ISS (International Space Station) created a robot called a "Personal Satellite Assistant." Powered by solar cells, this robot has sensors that can monitor pressure, temperature, and air quality. This feature can help astronauts know whether they have any problems with the space station environment. This assistant has a videophone for communication no matter where they are in the station. The videophone is also linked to Mission Control on Earth.

USING SPACE SCIENCE ON EARTH

Less that 1% in the nations budget is spent on the Space Program. People believe that they should not invest in the space program. They believe the money wold be more useful elsewhere. NASA posted information on its website that proves to the people how much we know today from space research. The exploration of space is known as an inspiration to people to explore the unknown and push the boundaries.

Gizmo Conclusion

There are a few factors that cause seasons. Well, the main factor of the cause of seasons is the tilt of the axis of the earth during revolution. While in revolution, the earths axis tilts causing a change in weather on a certain section of the earth (location depends on the earths location of the earth in its orbit). The reason its so hot in the summer is because there is more daylight hours (12 hours), and the sun is highest in the sky. The reason it is so cold in the winter is because there is only 10 hours of daylight and the sun is lowest in the sky. In conclusion, those are some factors of the seasons on earth.

Science "Perspective" paragraphs 9-16-08

The book, "Zoom" is an illustration book that makes the reader think and wander whats on the next page. The plot of this book is after every page the book would zoom out, referring to the title, "Zoom." This book has a lot to do with perspective because, when people crack open this book they first see an orange-red colored wave. When the reader(s) read this they think of many different things it could be, and when or what will the next illustration be on the opposite page. So it shows what that persons perspective is of what is in their minds. When I first saw the first illustration I inferred there wasn't really any point to the book, but as I saw the next page i realized there was a total point and all of it made sense. It was cool.

Finding different perspectives of things that other people think yet, getting the same solution you may get is kind of cool. Well when if I were to see something accurately, seeing it in a different perspective, I would find it different, yes. The reason why is that if knowing there was another perspective it would be kind of, well, different because you know that other people find the same solution using a different point of view. So it's kind of cool knowing there are many perspectives of people ending up thinking the same thing you do.
Altering perspectives is very cool because you can brainstorm many ideas to find a reasonable point of view. When you brainstorm perspectives you think of what might can, really, and possibly happen. When I see the word perspective I think of the word, "opinion" because, a perspective is like what you think will happen or what you think something is.

Many people (scientists or normal people) may be more interested in observing objects close up then objects far away. I believe people would want to observe objects close up because when you observe things from close up get very intact with the subject and u can get close and observe it more personally. While when seeing and observing objects from farther away, "what you see is what you get." You will not be able to observe it as much to the level as you would when you are observing a close up object.
Perspective is important in many ways. What is important about perspective is that its almost like you have an endless list of opinions that you can believe is a solution to what you think things are. When in perspective you can think your own way, without getting back-up opinions from other friends. Yet it is very good to compare your perspective with your friends to see if you and him/her may have been thinking the same things
so in many ways perspective can help you out

Enigma Box

"Enigma Box" Description

The "enigma box" (Puzzle Box) was a very unique and complex object. The enigma box is a black rectangular prism. On the box there are three holes. The box has 2 holes (one big one small) on one of the far sides and another big hole at the opposite side. As I observed the object when the water went down into the enigma box, the water didn't seem to come out immediately. The water came out after about 300 milliliters. Yet, the liquid would have stopped if not all 500 milliliters were to be put into the enigma box.

What I Think Was Inside the "Enigma Box"

When I was introduced to the enigma box i thought it was really cool, yet I started to think of what was inside the enigma box. When I saw that the water didn't come out immediately I thought there was a maze. I brainstormed to myself that if there was a maze not all 500 milliliters would come out. So I thought to myself about maybe there being stages in large quantities. So that the stages would be at angles to where the water goes down the box slowly. So the water ends after a certain amount of liquid is put down the enigma box.

5 Skills Scientists Use

The five skills scientists use are inferring, predicting, using models, observing, and quantitative and qualitative observations to observe objects. Scientists predict by telling what they think will happen in the future based on past experiences and events. Scientists observe objects by using one or more senses (smell, touch, hear, see, thought, and taste). Scientists also observe objects using models. Using models scientists may study the object up close and learn more about the object. They also observe objects quantitatively and qualitatively. Quantitative observations are based off numbers, while qualitative observations are based off of descriptions. Last, inferring an object is observing based on what you already know.

What is Really Inside the "Enigma Box"

The enigma box was a very complex thought yet, very simple. All the enigma box had to do with was a tube and a box. One end of the tube was at the bottom. While the other end was attached to a hole in the side. When the water was pored into the box the water level would increase. When the water level increased the water would go up the tube. As the water reached the highest point of the tube it would flow down the tube out of the side and come out of the side. Now the enigma box has been solved it seems so simple yet very complex.
