


1) Move to each station that is set up with
rocks. Spend two minutes at each station
and list at least 4 characteristics of the rocks
that you see.
2) Write down the definition for a mineral.
3) What is the difference between a rock
and a mineral?

Count off by 8 and get into groups.
Try to arrange the rock cycle with the
pieces given.
Rock Definitions

Igneous Rock:
– Magma and Lava cools and hardens to form

Sedimentary Rock:
– The accumulation of various types of sediments
compacted and cemented together

Metamorphic Rock:
– Heat and pressure cause existing rocks to
change their minerals and/or shape
Intermediate States


Magma/Lava
Sediment
Processes


1. Cooling/hardening
2. Compaction/Cementation
– Compaction: weight of overlying
sediments causes pressure pushing
sediments together
– Cementation: minerals dissolved in water
are transported and left behind to cement
sediments together
Processes



3. heat/pressure
4. melting
5. weathering
– Change in the physical form or chemical
composition of rock materials exposed at
the surface

What does the rock cycle that you
created tell us about the fate of rocks?
How are rocks classified? How does
this different from the classification of
minerals?
Can you figure out which station held
which of the three types of rock?
