Unit 8: Space Science
Objective(s):
1.
Open-Minded
2.
MATERIALS NEEDED:
1. Guided Notes
2. Pencil
SWBAT identify the four Galilean moons
of Jupiter by their physical properties.
SWBAT compare and contrast
meteoroids, asteroids, and comets
Relevance:
While we know much about the solar
system, there is still a lot of unknown
aspects for scientists and we must
keep an open-mind when researching
and learning about those unknowns.

Other Celestial Bodies
• Other than the planets, there
are many other types of
celestial bodies that are
orbiting in our solar system.
• What other celestial bodies can
you think of?
• Six of the eight planets have
moons that orbit them
including Jupiter which has
four of the largest moons in the
entire solar system orbiting it.
Moons
•
•
•
Moons are smaller celestial
objects that orbit planets.
All of the planets, except
Mercury and Venus, have
moons.
Scientists collect data about
their physical properties
using satellites and
telescopes.
What do planets orbit? What do moons orbit?
Galileo Galilei
•
•
•
During the 1600s, Galileo
Galilei discovered four large
moons orbiting Jupiter
using a telescope he made.
At the time, these were the
first moons ever found
orbiting a planet other than
the Earth.
These four moons are now
known as the Galilean
moons.
Stop and Jot
Why are the four largest moons of Jupiter known
as the Galilean moons?
Galilean Moons
•
•
The Galilean moons are four
of the six largest moons in
our solar system.
In order of their distance
from Jupiter they are called
– Io, Europa, Ganymede, and
Callisto.
What are the four Galilean moons called?
Io
•
•
•
It orbits Jupiter.
Io is the closest Galilean
moon to Jupiter.
It is the most volcanically
active body in the entire
solar system.
Europa
•
•
•
Europa is the second
Galilean moon from Jupiter.
It has an icy surface that
likely floats on top of a
liquid ocean.
The ocean underneath these
blocks of ice is an
environment that could
support life forms.
Ganymede
•
•
Ganymede is the third
Galilean moon from Jupiter.
It is the largest moon in the
entire solar system – even
larger than Mercury!
Callisto
•
•
•
Callisto is the fourth
Galilean moon from Jupiter.
It is the third largest moon
in the solar system.
It is also the most heavily
cratered body in the entire
solar system.

What are the four largest moons of Jupiter
called?
Other Moons
•
•
•
Titan is the second largest
moon in the entire solar
system – it orbits Saturn.
Composed primarily of ice
and rocky material.
The only moon known to
have a dense atmosphere.
Other Moons
•
•
•
Our moon is the fifth largest
moon in our solar system.
The surface is thick with
dust and rocks.
There is no water and no
atmosphere.

Asteroids, Meteoroids, Comets
•
•
The solar system contains
other objects than moons
and planets.
Some of these objects
include asteroids,
meteoroids, and comets.
Asteroids
•
•
•
•
Asteroids are the next largest
objects in the solar system
after moons.
Asteroids are rocky bodies
that revolve around the Sun.
Asteroids vary in shapes and
sizes but are mostly made of
iron, nickel, and stone.
Most asteroids in the solar
system can be found between
Mars and Jupiter – this is
called the asteroid belt.
Meteoroids, Meteors, and Meteorites
• Meteoroids are stone-like
or metal-like material that
travel through space.
• They may have been
formed from collisions
between other bodies in
the solar system or parts
of planets.
Meteoroids, Meteors, and Meteorites
• When a meteoroid strikes
the Earth’s atmosphere,
they burn up in bright
streaks and become
meteors.
• If a meteor survives and
hits the ground, it is called
a meteorite.
What is the difference between a meteoroid, meteor, and a meteorite?
Comets
•
•
•
•
Comets are icy bodies that release
gas or dust when heated.
Comets’ orbits are long, narrow
ellipses – more elliptical than any
other orbit.
They spend a very short amount of
time near the Sun before swinging
out beyond Pluto.
They are usually very hard to see,
but as they approach the Sun, they
begin to release gas and dust and are
lit up by the sunlight to form huge
tails.

Solar System BINGO
Each scholar has a different
BINGO card.
I will read the clues for
different types of celestial
bodies in the solar system or
various vocabulary words.
Silently use your notes to
identify the word and mark it
on your BINGO card.
We will talk about the word
before moving on.
