Things I've Learnt

There are many things that I've learnt throughout the project I made in Grade 6.
For example, I didn't know Earth had a second moon, named Cruithne.
It's good for me, because I knew more than my classmates about the solar-system.
But as everyone made a different project, everyone knew more about something than the others knew about that thing. In the end, we could all learn a bit from everyone's work. There was someone who made a project on 'Chocolate' or 'Medicine'. There were a variety of topics. I've really enjoyed making projects like that, and then presenting it. It was a lot of fun & we all can learn something new out of it! ^^ May it be about the topics, or about presentations & skills.

Can't go to church!

This morning, when I wanted to go to church, I couldn't. =(
I was so sad and upset. >=(
Jl. Pagarsih was blocked by the police, because there was an event there.
I really wanted to go to church, because it's the first whole Sunday after I got baptized..!
Only motorcycles and people going by foot were allowed to pass. And I went in a car. Even 'angkot's weren't allowed to pass! But my parents didn't want to park the car somewhere and go to church by foot. And I had to meet a friend after church! Now, my friend is angry at me. Eventhough I already sent her a message. She said, I haven't. She's going really mad now. :(
ALL THX TO THAT 'BLOCKAGE'!!!

Valentine's Day

Well, Valentine's Day is one of the greatest days of the year. It's a big day, especially for couples.
But I didn't really enjoy this year's Val's day.. He's so far away. And my friends forced me to go to IP (Istana Plaza).. In my opinion, it's so boring there. A place with nothing much to do. Plus, I had much homework to do for the weekend. And there will be an Indonesian test on Monday..
But in the end, I just went along. We didn't do really much there. I can't understand why they wanted to go there. We just went in & out stores. They just bought a few things, while I bought nothing. hahaha
To add to that, I got a sore throat & a cold. Therefore, I didn't feel really well.

Why I like the solar-system..?

Thx to Ma'am EL, I haven't forgotten this time to not just write about facts..
I wanna tell you why I like the solar-system so much.
I like it because it's just fascinating.
I love it!
The views & pictures taken of space are just fantastic. Wonderful!
They're colourful, mysterious, and they make me wonder about a lot of things..
So in Grade 6, I made a project on our solar-system.
I did some research and put it all together to get a nice piece of work done ^.^
I still have the project now, eventhough it's not really up-to-date today.
Because a lot of things changed since I left Grade 6.
For example, we don't call Pluto a planet anymore now, do we?
I don't wanna lose track about space anymore now.

Saturn

Saturn is one of the Giant Planets, too. It is the second largest Planet in our Solar-System. Saturn also is striped like Jupiter. But the stripes are neater than Jupiter. Jupiter’s stripes goes up and down like a wave that wiggles. Saturn’s stripes are straight.



Saturn has the biggest & thickest rings in our Solar-System. Its Rings makes everybody to their favourite Planet to watch out the Telescope. People in the past thought that Saturn has only one Ring. Then they discovered that there was a spit into three parts. So, Saturn has three Rings. The three rings are called the Cassini Division, Encke Division and the third one is the one that is the furthest from the Planet, separated with the other Rings and is called the F-Ring. The F-Ring is separated to the other Rings because there are one or two Moons blocking it. Those two Moons are called Prometheus and Pandora. They orbit the F-Ring around Saturn. The two Planets are called “Shepherd Satellites”, because they keep the F-Ring separated from the other two. The Cassini Division is named after the famous Italian-French Astronomer called Giovanni Cassini (1625 - 1712, because he discovered it. I don’t know the name of the other Astronomer for Ring Encke but, I know it must be First Name and then Encke for Last Name. The Rings are mostly made of Ice and Rocks. Saturn’s poles are more flattened than Jupiter’s. Not because it spins faster than Jupiter, it doesn’t. Only a few people know why. Saturn is not much smaller than Jupiter, but the Mass is only one third of Jupiter. This means that Saturn is lighter than water – if you would drop it into an ocean that is bigger than the Planet, it would float. Titan Saturn’s biggest Moon has the thickest atmosphere of any Moon in our Solar-System. It may even have oceans beneath the orange clouds.

Jupiter

Jupiter is the first Planet after the Asteroid Belt and the biggest Planet in this Solar-System. It is one of the Giant Planets. When we look at Jupiter from far we can see that it has stripes.


Jupiter is not like other Planets nearer to the Sun. It has many of other gases. A Galileo Spacecraft entered its atmosphere in 1995. It kept falling until the heat and the air around the Planet put it out of action. Jupiter’s size is enormous. It is 11 times the size of Earth. Its mass is over 300 hundred time bigger than Earth’s. It spins once in less than ten hours. For Planets that spins once in less time. They will get flat at the poles. Jupiter has a very, very, very thin ring around it. The ring is very faint. Even if you look close at it you can’t see it. Jupiter has the biggest moon in our Solar-System. That moon is called: Ganymede.

Mars

Mars is known as the Red Planet and it is the last planet from the inner Planets. Earth transits from Mars can be a really interesting thing to watch. Not just because it’s our home Planet. Also because we can often see both the Earth and the Moon. We can also see Cruithne sometimes with Earth and Moon.




The picture shows the transit of Earth that is going to happen on the 10th November 2084. Starting at nine o’clock in England. Sometimes if Mars is not so far away from us we can see it as a glowing red dot at night. On the first of November this year Mars will be right next to us. On the Planet Mars itself, the rocks, the dust (ground) and even the sky are reddish. The skies look orange or it is orange because the wind blows red-orange dust around. The dust was there billions of years ago not when it was formed. After the explosion of thousands of volcanoes. Lava is reddish orange. Mars surface looks like a desert if it was on Earth. Mars is further from the Sun. So it must be also colder. The temperature there is below freezing most of the time. In Mars you can’t breathe. There is no oxygen just carbon dioxide which we can’t breath. The air pressure is only one percent similar to Earth’s. It would bloat your body and turn your blood into gas. The surface of Mars has different looks. Some of the looks look similar to Earth and some like a desert. Mars has a huge canyon called Valles Marineris. It crosses one whole side of the Planet. The canyon is so huge that it could swallow the whole Rocky Mountains. Mars has thin clouds. Not as thick as Venus has, much thinner. As you know Mars also have craters and volcanoes. The Southern Hemisphere is more cratered than the Northern. Scientists, Astronomers and Companies that has got to do with Space have taken photographs and tested the soil. One field of dust dunes, near the Northern polar cap, is bigger than Earth’s Sahara and Arabian deserts put together. Mars has two Moons, one of them orbits Mars in eight hours and the other one in 28 hours. The name Mars was given, after the war: Roman God of War.
Is there a sign that there was life on Mars, once?
Mars is a dry planet with no liquid water, right now. Maybe there was water, but not anymore. There are many dried-up water channels and the red rocks also contained also contained a little bit of water. Scientists believe that, billions of years ago, that nearly all the volcanoes threw out gases and lava from the Planet’s boiling center. Water flowed from under the surface, maybe formed seas. The simplest forms of life, such as algae, may have existed. There was water on Mars for sure in the past. Maybe there is still some frozen water today. What I mean with frozen water is that, our Planet is not the only Planet that had the Ice Age. All the Planets in our Solar-System had Ice Age. The Ice Age on Mars was after the explosion of thousands of volcanoes. Mars is now completely lifeless today. The volcanoes there are now extinct (no longer active). One of them, that is extinct, is called Olympus Mons, is the largest volcano in our Solar-System. It is fifteen miles high.

Earth

The Earth is our home Planet, the Planet that we live on. Nearly two thirds of the Earth is covered with water. It is the largest from the inner Planets. If we were on Mars we could see transits of the Earth, but that is a Mars thing. We are not the only ones living on this Planet. There are also animals and plants living on this Planet. On this Planet there is more than 200 countries. The temperature on this Planet always changes. We never now what will come next if we don’t look at the Weather Forecast programs. Earth is the only Planet in our Solar-System that has life, right now (maybe). If live is possible on Mars is still being researched.. Maybe in 100 years =P

Here is Earth trapped in clouds (actually Earth was always trapped in clouds). I think I put too less for the topic ‘Earth’. Because I think you know everything already about our home Planet Earth.
