weather fronts

sumaries:
1.cold front: This forms cumulus and cumulonibus clouds, snow, rain, lightning, or normal clouds.

2.warm front: Can cause storms and rain or fog that can linger for days.

3.stationary front:Can cause rain, snow, fog, or clouds often for days.

4.occluded front: Can turn Cloudy rainy or snowy.

The front that I think brought snow was a cold front.

VOYAGE#3

Trip Itinerary and approximate latitude: Lima to Cape Town

Travel time: 15 days

Direction travelling: south then north easternly

Were you successful? yes

How many attempts? two

How were you successful? I went slightly into the winds in the opposite direction so they would blow me back on course.

What winds did you take advantage of or compete with during your travel?I used mainly pervailing Westernlies

VOYAGE#2

Trip Itinerary and approximate latitude: San Fransisco to Sydney @ approx 45deg lat.

Travel time: 13 days

Direction travelling: south westernly

Were you successful? yes

How many attempts? one

How were you successful? I used both sides of the trade winds

What winds did you take advantage of or compete with during your travel?I used both of the trade winds.

VOYAGE#1

Trip Itinerary and approximate latitude: Havana to London aprox. 27deg. lat.

Travel time: 9 days

Direction travelling: north easternly

Were you successful? yes

How many attempts? one

How were you successful? I traveled using the upward winds in that direction

What winds did you take advantage of or compete with during your travel?I took advantage of the North Westernly winds.

OZONE :) =]XD rofl ^V<>-}

Ozone is a form of oxygen, o3. In the upper atmosphere, it absorbs ultraviolet rays, thereby preventing them from reaching the surface of the earth. In the lower atmosphere it is a pollutant. Ozone is being depleted by a human produced chemical called CFCs witch contain chlorine, fluorine, and carbon atoms that are bound together. This tears apart the ozone and turns it into oxygen. There is a giant ozone hole right over Antarctica. SAVE TH O3!!!!

100 years ago, London's air was dark and dirty. This was called london smog. Factories burned coal, and houses were heated with coal, filling the air with soot. This makes it hard to breathe and fills the air with smog. The simplest way to prevent this is to burn less coal.

(Earth's atmosphere ----*******#####):(:):)XD rofl :)

The earth's atmosphere is much different than the moons. For one, all objects that come into earth are usually burned up due to our atmosphere. The atmosphere is earth is made up of 70% nitrogen, 21% oxygen, and 1% of other gases like argon. Our planet, Unlike others, also contains life. Our atmosphere protects us from the sun and gives us oxygen to breathe. Its pretty cool that there used to be no oxygen at all, but tiny bacteria converted the carbon dioxide into oxygen. The moon has very little atmosphere. Caters and footprints are still on the surface of the moon because there is no forces to erode them away. The is also no water on it to sustain life. Because of extreme atmospheres found in the other planets, no planet but Earth has intelligent life on it. No life that we know of anyway. Earths atmosphere is what makes life possible on Earth.

Space Exploration part 2

Space Exploration

Summaries

The science of rockets:
NASA used to use atlas rockets to put satellites or spacecraft in space. These rockets had three parts. The Atlas witch launched the rocket into space with it fuel cells, then the Centaur, witch maneuvers it into the proper orbit, and finally, the third stage witch is the payload, or the satellite or spacecraft realeasement. Now they've been upgraded and offer launch company satellites into space.

The space program:
NASA's job is basically to explore space. So they needed to put humans in space to explore it. NASA eventually after a few tests was able to send people into space. Project Apollo put humans on the moon. Apollo 13 attempted to put people on the moon again, but was unsuccessful. The astronauts barely made it home alive. By 1972 three other NASA spacecraft had explored the moon. These other observers sent there found ice deposits on the moon.

Exploring space today:
On the international space station they have designed a working “helper robot.” This robot can float and is powered by solar energy cells. It can monitor pressure, air quality, temperature, and has a videophone so astronauts can communicate with each other. They also perform regular safety sweeps on their own.

Using space science on earth:
Many people think space exploration is a waste of money, but NASA says that it helps our economy. We have also had many breakthroughs here on earth because of what we learned in space. NASA just pushes people to explore the unknown.

Gizmo paragraph-seasons

According to the research done, the seasons are cause by the tilt of the earth witch is 23.5 degrees. When the sun shines at the earth, it hits the side that is tilted toward it more. This side is then in summer while the other side is in winter. When the sun is hitting no angle in particular, both hemispheres have the same temperature and amount of day and night. This is called Equinox. After Equinox the hemispheres start to change temperatures in different ways. One goes into winter again and the other into summer.

*Zoom*

Zoom is just an endless maze. You automatically infer that you know what is going on and you’re all that is happening but it your tiny frame of view is just a small part of the detail of what is all out there. Compared to space our world is an unnoticeable speck. In the zoom book you infer a scene is only that, when it's really a scene in a scene in scene ECT.......
Take a picture of a wall. Take a picture of the picture and keep repeating. It never ends. Our perspective of things is actually very limited. We can go millions of powers of ten (we are not able to but it’s possible) smaller or larger, and we as humans can only see a few of them. Kind of puts things into perspective. There is so much going on that we don't know about.

Enigma box

In order to attempt to solve the mystery of the Enigma box, I had to use my scientific observing skills. Inferring was a big part of the process because I had to take the data I knew and make a guess as to what happening inside the Enigma box. I also had to observe what was happening in order to make a good inference.

The Enigma box is a 3D rectangular prism. It has one big hole on top. After 470mL is pored in through the large hole the water rushes out through a tube on the bottom. Before it reaches the 470mL mark, it very slowly drips out the bottom.

 I think the Enigma box works like a fish tank water vacuum. I don't remember what its called, but I know water sticks together so once it starts flowing it keeps on flowing until all the water is vacuumed out. With the tube you stick in the fish tank and it makes all the water run out through the tube. I think the Enigma box works something like this.

The Enigma box really uses a siphon. The water fills up until it reaches the top of the siphon. Then gravity pulls the water down the tube. Water sticks together so it pushes almost all the water out through the tube. That is how it works.
