Scientific reports.

We had to write a scientific report on a planet of our choice.

Uranus

Uranus was discovered in1781.  It is the seventh planet.

The temperature is never higher than 170oC below zero.  It is the third largest planet.  Uranus is composed of rock and ice.  Uranus's blue colour is the result of absorption of red light by methane in the upper atmosphere.  Uranus has about thirty rings.  Uranus is a gas planet.

It would be good to find out more about Uranus.

SUN

Our sun is not unique in the universe.  It is a common middle sized star which scientist have named Sol after ancient roman name.  This is why our system of planets is called the solar system.  There are trillions of other stars in the universe just like it.  Many of these stars have their own systems of planets, moons, asteroids and comets.

The sun was born in a vast cloud of gas and dust around 5 billion years ago.

Earth

Earth is the third planet from the sun, and the fifth largest of the eight planets in the solar system.

Earth is the only planet in the solar system with creatures living on it, it is also the only planet with h20c as a liquid on it's self.

Earth is a mass of rock, melted rock and hot gasses.

Planet earth is not hot and not to cold making a perfect environment to live in.

I think earth is a good place to live.
