Rocks and Minerals!
By Amanda Tollefsen
2rd Grade
What is a Mineral?

Minerals are what rocks come from

There are many different types

They grow even though they aren't alive

Most minerals grow in crystal shapes

Many sometimes grow in the same place, so
different crystals all grow together and become
very big
How do Minerals grow?

2 WAYS

When magma from a volcano cools


When water evaporates away so the minerals are
left behind.

How do you know if it is a Mineral?

Each has a different name and different traits

Look at the color and shape

Is it hard?

Does it look glassy or dull?


*all of these are ways of determining what kind
of mineral you are looking at

What is a Rock?




You see them in the
mountains and canyons!
Its a solid
New rocks are always
developing
Made up of a mineral or
sometimes more than
one mineral
3 Types of Rocks

Sedimentary: when
already existing rocks
and fossils come
together to form a rock


Igneous: when magma
turns into a solid



Metamorphic: when an already existing rock
gets heated really hot, and it turns into a new
rock

Examples

Metamorphic

(Marble)

Sedimentary

(Conglomerate)

Igneous

(Obsidian)
Rock Layers



History is studied by
looking at the layers of
rocks.
What is in the rocks?
The bottom layers are
older than the top
layers.

Activity Time

We are going to be
making our own
Metamorphic Rock!

Supplies: (each person)

1 Baggy of playdough

2 pieces of wax paper

1 Rock paper

Hammers that you will
share with your row (I
will pass these out)
•
*Get colored pencils if
you don't already have
them at your desk
Steps to Making your Rock!
1. Put a piece of wax paper down on table (as your mat
to work on)
2. Make little balls with your playdough
3. Put the little balls side by side in any order you want
4. Put other piece of wax paper on top of playdough
(making a sandwich)
5. Hammer them together flat
6. Form a rock shape with your hands
Activity Continued..




All of the small balls of playdough represented
what?
Different little pebbles or rocks (sedimentary or
igneous)
When you hammered your play dough what
happened?
With the pressure from the hammer and heat from
your hands a metamorphic rock was formed
