Fronts

COLD FRONTS
Cold fronts work like this, the cold air moves slowly toward the warm air, when the cold air reaches the warm air. The cold air pushes the warm air upward, by doing that the air with precipitation. Moves up into the dew point, and since there is so much precipitation the droplets form quickly and fall out of the cloud on to Earth.

WARM FRONTS
The warm front works like this, the warm air starts to move toward the cool air. the warm air slowly goes up above the cool air making the cool air warmer, and making a cloud with precipitation. The cool air soon disappears because the warm air takes over.

STATIONARY FRONTS
The warm air and cool air go head on, they start pushing and shoving each other. First the warm gets pushed a little then the cool air gets pushed a little. And all this pushing and shoving gets them no where, that's why it's called a stationary front. Also all this pushing and shoving starts to make a cloud in the middle, a rain cloud or snow or etc.

OCCLUDED FRONTS
There are two cool fronts with warm air in the middle, one of the cool airs start to move. While the other just stays still, when the other cool air starts to move, lets name the cool air moving CoolM. CoolM pushes the warm air that is in between CoolS and CoolM upward. The warm air splits in half and one goes to CoolM's side and the other to CoolS's side. CoolM and CoolS and the warm air start to make a cloud. The cloud rains, snows, hails, etc. on CoolS.

Which type of front occurred this week to bring the cold weather and then snow?
This week we had a cold front bring in all of the snow and cold weather.

Atmospheric Factors Effecting Climate

Ozone

The Ozone is a molecule,with three oxygen atoms. The Ozone blocks harmful UV rays from hitting us and the Earth. In different layers of the atmosphere the Ozone can be good or bad. In the Troposphere, the Ozone contributes to the smog and greenhouse gas effect. Also it can act as a chemical oxidant, which means it can rip oxygen off you, animals, plants, etc. In the Stratosphere, the Ozone is mostly here. This is where most of the protection is from the UV rays. The Mesosphere, is where there is hardly any Ozone; but the Ozone still protects us from some of the UV rays. Ozone depletion is when the Ozone is being destroyed more than it can produce. Which means the Ozone is disappearing faster than it can produce more Ozone. Also when the CFCs/chlorofluorocarbons, reach the Stratosphere they release chlorine atoms. The chlorine atoms rip off the oxygen atoms from the Ozone, which depletes it.

Greenhouse Gas

Greenhouse gas has a big effect on the world and the environment. The actions we do, effect the greenhouse gases. Whatever we do either helps or makes things worse for the world. Why are greenhouse gases bad? Well they are the cause of global warming, you know the thing that's melting the ice caps and killing polar bears. Yeah, that! Greenhouse gas is made up of water vapor, carbon dioxide, and methane. The atmosphere is trapping those gases, which makes a hole/holes in the Ozone even bigger. And with such a big hole/holes in the Ozone, there's less protection against the harmful UV rays. We the people should be worrying about this crisis, us the children/teens should also worry about this crisis. Because we'll be living with it, and what we do now could either fix it or make it even worse. So please try to help, by saving energy, walking to school, carpooling, and anything else you can think of to help.

Earth's Atmosphere

The Earth and the Moon or a planet with no atmosphere they have a very different atmosphere. Earth's atmosphere is able to hold life, and a suitable temperature for life. With no atmosphere there is no stable temperature, when a meteoroid is headed for the planet with no atmosphere. The meteoroid won't burn up coming through the atmosphere, so it will hit the planet and make a crater. Also with no atmosphere land marks such as a foot print will last longer because there is no erosion or weather to wash it away or destroy it. Earth's atmosphere holds solids, liquids, and gases in it, also the atmosphere will burn up any meteorites that try to hit Earth. That's why Earth is so much different from the Moon or any other planets with no atmosphere.

Life Beyond Earth

Space Exploration

NASA

Since The 1950's NASA has been using Atlas rockets to launch probes and satellites up into space. The rockets have three stages and are 59 meters high. First stage is wear the liquid and solid fuel boosters, they launch the rocket into space. Second stage uses liquid fuel to get into proper orbit after the launch. Third stage holds the probe or satellites that need to be launched into space.

NASA started in 1958, it had a mission and the mission was to explore space. Their first mission was to see if a human could live on Mercury. A few missions later they had Apollo land on the Moon. This was a successful mission and the birth of space shuttle programs. Even though Apollo 13 and other missions failed they haven't given up and are still doing missions today.

NASA has made a small robot for the International Space Station(ISS). It can float to and astronaut and tell them if there's a problem in the (ISS) environment. Since the robot is small it can easily monitor small spaces no adult human could get to. It's solar powered and it has little fans so it can move and follow the astronaut. It checks the air quality, temperature, and pressure for the astronauts so that nothing bad happens.

NASA says less that one present of the U.S's budget is spent on them/the program. Many people argue against funding NASA, most say that the money needs to go to health research and education instead. NASA has learned so much about the universe from all of the exploration and the program. All of this research has produced a lot of satellite communications. Also NASA supports many jobs, so they not only help with understanding the universe. But they also help the economy by supporting the jobs the U.S. has.

Gizmo

Our science class had to do a Gizmo about how the seasons changed and why. The Earth is tilted on an axis that revolves around the sun counter clockwise. The longest day of the year is June 21. Since it's the longest day of the year, the earth is heated longer by the sun's rays and makes the temperature rise. The shortest day of the year is December 21, the sun's rays don't heat the earth as long so it's not as warm. When the sun is directly hitting the Northern or Southern Hemisphere it's summer. Unlike when the sun isn't directly hitting the Northern or Southern Hemisphere it's winter. In between the direct sunlight and indirect sunlight are Fall and Spring.

Zoom By. Istvan Banyai

the book ZOOM by. Istvan Banyai, had many assumptions, but usually the assumptions were wrong. In the beginning of the book when I saw the picture, I immediately thought it was how the sun was created.But really it was only the close up of a roosters crown.The book zoomed in and through the book you saw it zoom out page by page.But pretty much with every new perspective when the book was zooming out. I always had a new prediction in my head.
Once when U was drawing a flower in a vase. I was having some difficulty drawing it. So I decided to move across the room and closer. What I found out was that when I moved I saw a whole different scene and perspective. Then what I had drawn in the beginning was totally different from when I moved. the new perspective helped me a lot with my drawing.
Scientists who study atoms and molecules would probably be interested in close up data. Because you see more detail in the object unlike far away. Unlike a scientist studying astronomy and the planets would want a farther away view. Because you can see more when your farther away.But both perspectives are important in astronomy, because when looking inside a planet we want to see all the details. Unlike when we are studying the planets and universe we want a far away view.

New Post

During the class room demonstration, I used five skills. Scientists use everyday to study the natural world. I observed the Enigma Box from the out side and in the demonstration. I made a model of what the Enigma Box looks like from the outside. I also predicted what was in side of the box. Even though those were only three skills, there are two more; which are classifying and inferring. Also the scientists all around the world need these skills to complete and succeed in their studies in the natural world.
In the class demonstration, I observed three actions. My first observation was when Mrs. Casey poured 250mil. of yellow solution into the Enigma Box a slow but steady drip started into the cup. My second observation was when Mrs. Casey poured 50mil. more into the Enigma Box, a faster and more rapidly drip accrued into the cup. But when Mrs. Casey poured 150mil. more yellow solution into the box the yellow solution drained out of the box and into a cup.
My prediction on what is inside of the Enigma Box is a sponge. I think a sponge is inside of the Enigma Box. So from the inside it looks like a black, shiny, hard box. and on the bottom of the box is a sponge. I think the sponge is blocking the tube that drains all the water out of it. Since the water was dripping I believe the sponge soaked up the water and didn't let it out very fast . But when more water was added the sponge couldn't hold anymore water and it started to drain out.
To find out that my prediction was wrong after the demonstration. Mrs. Casey told us what was really inside of the Enigma Box and it wasn't a sponge. There was really a tube that was folded together, one of the ends was at the bottom to get the water and the other where the water drained out. This is how the experiment worked, when 300mil. of water was poured in the pressure from the water and air pushed some of the extra droplets from the other classes out of the box into the cup. That was why there was a slow steady drip. But when 150mil. more was poured into the box the water line reached past the bend in the tube. With gravity and pressure the water that was being poured in started to drain out at the bottom of the tube and into the cup.
