A 'Moonth' of Phases

  1: In our model, the big ball represented Earth, the lamp represented the lamp, and the little ball represented the  moon.
  2: The amount of light that I saw on the little ball depended. Sometimes I saw it over the whole ball, sometimes I saw one half lighted, sometimes I saw a quarter lighted and sometimes I saw a creasent or gibbous or nothing. These represent the phases that the moon is.
 3: After one full turn, I saw the whole ball lighted. When completing one whole turn. the moon completed all 8 phases and is starting again.
4:Whatever I could see it or not, half of the ball was always lighted. When the moon was new, it was  created by an eclipse. At that point, the moon blocked the sun reaching Earth and it placed itself right in between Earth and the sun.
5: Making a model helped me understand the phases of the moon better. It is still a bit confusing but after it, I think I understand better. One disadvantage of models I think is that they are not always exact. It shows correct information but it is not accurate.

Reasons For the Seasons

   
Summer
·         More light
·         More shadow because there is more light on the surface.
·         The North pole gets more heat
·         The South Pole gets less heat

Winter
·         Less light because the sun is further away
·         Less shadows because the light is further away
·         The poles are colder, because the surface is blocking the poles from the sun

1:When it is winter in the Northern Hemisphere,in the part which receives most sunlight, the Southern Hemisphere, receives summer.
2: In v the summer, there is less shadows because the light is mostly direct. The area gets a bit of the shade but not too much.
3: The heat will increase because the amount of the area that the heat covers will grow. There will now be heat on more of the surface than before.
4: The areas on which it is always cold are the poles. Or, the sides facing up and down on the ball. It is the warmest near the Ecuador or the centre of the ball. This is because the centre of the ball always receive direct light from the lamp, and the poles or the sides facing upward and downward receive the least amount of light because they are the furthest from the sun or the light.
7: The seasons are created by the different positioning of the sun. Where there is most heat and sunlight, it is summer. Where there is the least sunlight and is the coldest. It is winter there. Spring and fall are in between.

Meteorite Punches Through Oslo Shed

    One family in Norway was lucky and they got a huge souvenir for free. On Monday, the Thomassen family found a broken roof of their hut, and a meteorite in it. The rock weighted about 585 grams and it split in two. The family decided to keep the rock and put it in a museum. Serge Koutchmy, a researcher said that the family is very lucky. Firstly because, it is very rare for a meteorite to land in a inhabited area. Second, it didn't cause much damage, and lastly it is worth a little fortune, its worth 5,000 kroner or $876 per gram.
   I think this family is very lucky because they got a souvenir for free. And it is quite a adventure to experience the foundation of a meteorite or anything from space. I think if something like that landed in my house, I would definitely keep it, and be proud that I found something like that, and I would make my friends from school jealous.
