  THE SOLAR SYSTEM The solar system is a planetary system where you can find the Earth and seven more planets. Moreover, there are a lot more astronomy objects that round directly or indirectly in an orbit nearby the sun. The sun takes up 99,75% of the solar system, and the biggest part of the rest is found on the eight planets, there are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Their orbits are practically circular, and they round in that order nearby the sun.  The moon is an astro like the earth. On the Earth we see it floating in space, the moon is a sphere, like a ball fifty times smaller than the Earth. On the moon it seems like it isn’t any water, it’s a dry desert. The moon takes 28 days to do a whole turn to the Earth. The moon also has a rotation move in itself. In actuality the moon makes a non-circular orbit around the Earth and moves between 350-400 thousand km away from us. The moon's diameter mides 3.470 km,  which is 27% of the Ea...

  COMPASS INTRODUCTION The Compass is an instrument for orientation that marks the north, south, east and west. The compass marks, with a magnetized needle, the north, because the earth has a kind of giant magnet (magnetism), which exists naturally, inside the earth, and which goes from the north pole to the South Pole. If the magnetized needle inside the magnet points north, it is because the magnetism has its south end, which is the opposite of the magnet. The compass has long served as a GPS, as it does not need any electricity. MATERIALS -One slice cork stopper -One needle to sew -One magnet -One small container with water  PROCEDURE First we cut a quarter of cap cork, with a cuter. After we insert the needle in the cork stopper, because it goes through completely. Next we fill the small container with water.  Then we rub the needle with magnet, magnetize the needle.  Now we put, the slice cork stopper and needle together in the container with water. Finally, if ...

  THE BIG BANG Most astronomers believe the Universe began in a Big Bang about 14 billion years ago. At that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead. It was hotter and denser than anything we can imagine. Then it suddenly exploded. The Universe that we know was born. Time, space and matter all began with the Big Bang, all of this in a fraction of a second, and it is still expanding today. As the Universe expanded and cooled, energy changed into particles of matter and antimatter. Over the next three minutes, the temperature dropped below 1 billion degrees Celsius. <iframe src="https://giphy.com/embed/FrXZ65U64YJIuJh86l" width="264" height="480" frameBorder="0" class="giphy-embed" allowFullScreen></iframe><p><a href="https://giphy.com/gifs/FrXZ65U64YJIuJh86l">via GIPHY</a></p> Jana and Júlia
