•Have students fill in Focus Questions as they view the video. Discuss
after the video.
•Put samples on each table group, “Rock or mineral.” “Why?” Discuss.
•Revisit Anticipations Guide, correcting all False statements.

How do we
distinguish
between
rocks and
minerals?
Mineral
Inorganic
Inorganic, solid
materials found in
nature, made of like
particles.
Not formed by plants
or animals.
Rocks
Two or more minerals
combined.
Crystals
An orderly, repeating
pattern of atoms.
What is a Mineral?
• Naturally occurring
• Inorganic
• Characteristics have constant
chemical composition
• Distinctive physical properties
• Crystalline structure
• Formed from magma or water
What is a Rock
• A rock is a naturally occurring aggregate of
minerals and/or other rock fragments.
• Rocks are classified based on their method of
formation.
How do we distinguish between
rocks and minerals?
Rocks
Minerals
Rocks don’t always
look the same
throughout
Rocks are made up of
2 or more minerals
Minerals always look
the same throughout
(homogenous)
Minerals are NOT
made of rocks
