Sixth Grade SOL 6.8
Questions you must be able to answer
• 1. Describe the planets and their relative positions
from the sun.
• 2. Compare the characteristics of Pluto to the planets
and explain its designation as a dwarf planet.
• 3. Design and interpret a scale model of the solar
system.
• 4. Explain the role of gravity in the solar system.
• 5. Compare and contrast revolution and rotation and
apply these terms to the relative movements of planets
and their moons.
• 6. Model and describe how day and night and the
phases of the moon occur.
• 7. Model and describe how Earth’s axial tilt and its
annual orbit around the sun cause the seasons.
• 8. Describe the unique characteristics of planet Earth.
• 9. Discuss the relationship between the gravitational
pull of the moon and the cycle of tides.
• 10. Compare and contrast the ideas of Ptolemy,
Aristotle, Copernicus, and Galileo related to the solar
system.
• 11. Create and interpret a timeline highlighting the
advancements in solar system exploration over the
past half century. This should include information on
the first modern rockets, artificial satellites, orbital
missions, missions to the moon, Mars robotic
explorers, and exploration of the outer planets.
Our Solar System
• The solar system consists of the sun,
moon, Earth, other planets and their
moons, meteors, asteroids, and comets.
Each body has its own characteristics
and features.
• Planets revolve around the sun, and
moons revolve around planets. A planet
rotates upon an axis.
Our Sun is a medium sized
star that is the center of
the solar system
The first 4 planets are
Mercury, Venus, Mars, and
the Earth. These are the
inner rocky planets

The four remaining planets,
Saturn, Jupiter, Uranus,
and Neptune are the outer
gaseous planets

Space Objects
• Asteroids are objects orbiting the sun that are too
small to be considered planets, the belt is found
between Mars and Jupiter.
• Comets are balls of dust and ice that have a long
tail that always points away from the sun.
• Meteors are streaks of light that are created when a
meteor is burned in the Earth’s atmosphere
• Meteorites are meteors that hit the Earth’s surface.
• Meteoroids orbit the solar system
Dwarf Planets
• Dwarf planets are round and orbit the Sun just
like the eight major planets. A dwarf planet is
much smaller than a planet (smaller even than
Earth's moon), but it is not a moon. Pluto is the
best known of the dwarf planets
• A dwarf planet revolves around the sun, and can maintain a nearly round
shape as planets do, but it cannot move other objects away from its orbital
neighborhood.
Let’s Make a Model
• The distance between planets and sizes of the
planets vary greatly. The outer, “gas” planets are
very large, and the four inner planets are
comparatively small and rocky.
On one end write the sun and the other Pluto.
Fold your paper in half, at the crease write Uranus.
Fold Pluto up to Uranus, at the crease write Neptune.
Fold the sun to Uranus, at the crease write Saturn.
Fold the sun to Saturn, at the crease write Jupiter.
Fold the sun to Jupiter, at the crease write Asteroid Belt.
Fold the sun to asteroid belt, at the crease write Mars.
The remaining amount of paper is divided into Mercury,
Venus, and the Earth.
Now is this what you thought the Solar System looked like?
Seasons are caused by a combination of the tilt of
Earth on its axis, the curvature of Earth’s surface
and, thus, the angle at which sunlight strikes the
surface of Earth during its annual revolution around
the sun.
The moon appears to go through
phases because of a person’s
perspective from the Earth as the
moon revolves. One side is
always lit, but we can only see
part of it depending on its position
• The phases of the moon are, new,
waxing crescent, first quarter, waxing
gibbous, full, waning gibbous, last
quarter, and waning crescent
The period of revolution is when an
object travels around another. For a
planet, one revolution is one year
Gravity is a force that keeps the planets in
motion around the sun. Gravity acts
everywhere in the universe.
The period of rotation is
one spin on an axis. For a
planet one rotation is one
day
As Earth rotates, different sides of Earth face toward or
away from the sun, thus causing day and night, respectively.
A solar eclipse occurs when
the moon passes between
the earth and the sun,
casting a shadow on the
earth
A lunar eclipse occurs when
the earth passes between
the moon and the sun,
blocking the sunlight from
the moon
A neap tide occurs when the moon
is perpendicular from the sun.
Smallest amount between low and
high tide.
• A spring tide occurs when the
moon is in line with the sun. The
highest of the tides
• There are approximately two high
tides and two low tides in each
24- hour cycle
The ideas of Ptolemy, Aristotle,
Copernicus, and Galileo contributed to
the development of our understanding
of the solar system.

Geocentric model
Heliocentric
John Glen was the first
astronaut to circle the
earth
Neil Armstrong was the
first man on the moon
The space station is a joint
effort to create living
quarters in space
So what has space
exploration done for us?

• Research and answer the questions
anyway you would like.
YEAH!!!!!!!!!
• You are almost as
smart as a sixth grader
