Earth Science Rocks!
Opening: Solar System Song
Work Session:
Complete Solar System Foldable
Closing: What’s the weather like on Mars?
Learning Standard: We are learning about
our Solar System because we need to know
about our neighbors.
The Planets in our solar system
What is an AU?
An astronomical unit (AU) is the
average distance of the Earth
from the sun.
1 AU = 93 million miles!

What features do the gas
giants have in common?
Pluto
(dwarfplanet)
• SURFACE: Ice and rock
• ATMOSPHERE: Sort of has one…
• TEMPERATURE: -387°F average
• LIQUID WATER? No
• MASS: 0.002 Earths
• DISTANCE FROM SUN: 39.5 AU
• REVOLUTION PERIOD: 248 years
• MOONS: 3 (Charon is an icy companion moon)
• RINGS: None
When Pluto is closer to the sun in its orbit, the
warmth from the sun heats up the frozen ices of
nitrogen, methane and carbon monoxide on Pluto's
surface. These ices vaporize and form a
temporary atmosphere. When Pluto moves farther
from the sun, the atmosphere freezes and falls
back onto Pluto's surface.
