stationary fronts

a stationary front occurs when 2 equal air masses of cold ad warm air meet, they make storms and stay in place for a while.

occluded fronts

occluded fronts occur when 2 cold air masses surround a warm air mass. ground temperature cools down, and the warm air rises.

warm fronts

warm fronts occur when a larger mass of warm air collides with a mass of cold air. the warm air rises above the cold air mass, and slows everything down, and makes a lot of storms.

cold fronts

A cold front occurs when a mass of cold air slams into a mass of warm air, driving it up and making storms. these end the fastest.

trip itinerary: c

Were you successful?
yes.
How many attempts?
2... darn Magellan.
What winds did you take advantage of or compete with during your travel?

I fought with the trade winds and horse latitudes shortly, then used the westerlies to go faster.

1
What winds did you take advantage of or compete with during your travel?

I competed shortly with the northern trade wind, but I got out of it and used the prevailing westerlies.

Were you successful?
very.

What winds did you take advantage of or compete with during your travel?

I competed with none, I was in the trade winds which I took advantage of.

Atmospheric Factors Affecting Climate

photochemical pollution is a brownish haze usually above sunny cities. It is made when certain pollutants react with ozone and sunlight. It is harmful and irritating to the eyes and throat, can damage plants and pollute water. A way that we can help stop this is by taking public or energy saving transportation, such as hybrid cars, buses, and bikes.

The Space of Today




The International Space Station

• This is International space station.
  

• 
  An artificial satellite home.
  


• 
  It has many researching labs.
  


• 
  astronauts live and work there.
  
  

Space Shuttles

• 
  This is a space shuttle.
  
  

• 
  Space shuttles are reusable spacecraft.
  


• 
  Their biggest advantage is it's reusability
  
• launches with a rocket lands like an airplane
  

The Space Probes

• 
  This is a space probe
  
  

• space probes have 3 functions
• generating electricity, communication, scientific instruments

The difference with atmosphere

Earths atmosphere differentiates it from other celestial bodies. The atmosphere itself allows water and gases to stay inside the atmosphere instead of flying off into space. The gases that comprise the atmosphere allow life, by blocking harmful ultraviolet rays and giving the materials needed to make organisms. Also, by having an atmosphere, we have weather, causing erosion and changing the planet. Energy is also restricted and released, causing much less drastic temperature changes than other planets.

Their is one definite reason that there are seasons. the reason is how far above or below the sun the earth is. when it is higher, the north gets indirect sunlight, so it gets less energy, and thus less heat. However, the south is facing the sun more, and has a more direct angles, and more heat. the opposite is true as well, when the earth is lower, the south gets less and the north gets more.

perspective

In the book zoom, by Istvan banyai, an object is shown zoomed very close in, and as it goes out what you think of it changes greatly. I made several inferences, which after a short while turned out to be correct. It deals with perspective in the way that by looking at something differently, your opinion about it changes. As he zoomed out, I realized how tiny that once gigantic thing was.

Many times in my life, I realized that from a different perspective, things look very different. When I was very small, I thought that 3 years was as long as it took for all of history, but where I am now, I realize that 3 years aren't as huge a time frame as I thought, and one hundred isn't that monumentally huge of a number.If I put myself in the shoes of another person, my view on things would change. In this years presidential running, if a McCain voter thought of the race as an obama supporter thought of it, he might see some points and issues differently.

Scientists need to view alot of information to do thier job, and perspective is important for that to know on all scales the information about the object. A botanist might be more interested in studying the cells and genes of the plant versus just the plant. An artist might be more interested in the small writing he put on a penny, rather than the penny itself. It would be very helpful in astronomy to have both ends of perspective when studying planets, to know its general shape and spin or axis, or to know what its soil and surface are like.

enigma box

scientists use many tools to accomplish their jobs. these tools are not like hammers and screwdrivers, but are mental tools like reasoning , inferring, and others. they observe to gather info about what something is. they infer by looking at and deciphering or analyzing what is happening or what has happened. they predict using prior knowledge to guess what will happen.

I saw a certain amount of water go into the small box before it all came out. it was black and had 2 holes in the top and 1 plastic tube sticking out of the bottom. in the top, there was one small hole and 1 large 1, I think the large was 2 cm in diameter and small one was one one cm. water was poured into the top and shortly after rushed out of the bottom.

Inside of it, I think here is nothing. the water has suction, just like a straw with a finger on top. also,there might just be a cup with a weight. there are many more heroes, but i think most are impossible. i think there might be a wall that goes down at a certain weight, letting the water through.

when i first saw the diagram of the enigma box, i was confused. i thought all my guesses were very wrong, until it was explained. it operates on air pressure, being that when there is enough it all comes shooting out pushed by the air pressure. it is, as I guessed, like a straw
