In this lesson, you will learn about the four inner planets, and you
will learn their common characteristics.
The four inner planets are:
Mercury
Venus
Earth
Mars
*They are called the inner planets because they are the planets
closest to the sun.
*Let’s look at each of these planets more closely.

Now that you have looked at each of the planets, did you notice any
common characteristics among the inner planets? Here are some
things that you should know:
—The inner planets are all small and rocky which is why they are called
the “Rocky Midgets.”
—The inner planets are all solid.
—The inner planets are all warmer because they are closer to the sun.
Here are some other websites you can explore to find out more about

*Complete part one of the attached worksheet “Inner Planets” to
show what you have learned so far.
*Complete part two of the attached worksheet “Inner Planets” to
show what you have learned so far.
Now, you get to create a new Inner Planet. The planet needs to
fit the other characteristics of the Inner Planets (a Rocky Midget). You need to name your planet and give a basic description:
distance from sun, rotation time, revolution time, size, temperature, atmosphere, does it have moons, etc. You also need to draw
and color of picture of the planet you’ve created.
