The document describes our solar system and provides information about the planets. It includes an objective to describe the solar system including the sun, earth, and other planets/moons. There are sections labeling the inner and outer planets, with tables giving the diameters and distances from the sun of the inner planets Mercury, Venus, Earth, and Mars. Details are also given about the planet Mercury.
2. Objective

Editor's Notes
We are going to learn about the different kinds of objects in our solar system. When we finish this lesson we will be able to tell someone about the solar system and name the planets and other important objects included in it.
Remind students that Earth is the third planet.
Review the names of the planets in order.
Discuss mnemonic devices to remember planet order.
Click title and each subsequent object for the next to appear.
When we study the planets we divide them into two groups.
The groups are separated by an asteroid belt.
Where is Earth located?
Which inner planet is smallest? Largest?
Which is closest to the sun? Farthest?
What other comparisons can we make?
Make comparisons to what we already know about the Earth.
