Unit 1: The Solar System

Hi everybody!
In this unit we are going to learn a lot of things.

SCALES IN THE SOLAR SYSTEM







And what about if we compare our Solar System with other bodies from the Universe?

Autonomous zone 
We are going to represent The Solar System in a mural using small scale sizes and distances. To do so, we are going to use the following site, where we will calculate the necessary data.

Follow the next steps:
1. Go to the website clicking in the image below.
2. Enter the Sun diameter (we recommend you to use 50 or 100 centimeters).
3. Click calculate.

Then you will obtain a table like this with our model diameters and orbit distances:

4. Each team is going to be responsable of making an element of the Solar System and we will built a model of the Solar System that will be represented in the corridor.

5. We are going to use cm instead of mtrs to represent the distances among the Sun, the planets and the asteroids:

The Planets of the Solar System:

Key concepts:

- The inner or rocky planets are:



. Mercury, Venus, Earth and Mars.
. Small.
. With rocky surfaces.
. They have few moons (or natural satellites).
. High density.
. Orbiting at a fast speed around the Sun.

The outer or gaseous planets are:



Jupiter, Saturn, Uranus and Neptune.
. Big.
. With a gaseous surface.
. They have rings and many moons (or natural satellites).
. Low density.
. Orbiting at a slow speed around the Sun.
