Learning Intention
We are learning to….
• Identify the layers of the Earth.
• Recognizes that the Earth’s crust is
made of rocks and soil.
Success Criteria
I will be successful if I am able to ….
• Identify the layers of the Earth.
• Make a model out of clay or using colour
papers and label the layers of the Earth.
The Layers of the Earth
Four main layers of the
Earth
The
Earth’s Layers are divided into four
main layers.
*Crust
*Mantle
*Outer Core
*Inner Core
Crust
 The
Earth’s crust is like the skin of an
apple. It is very thin compared to the
other three layers.
 The crust makes up 1% of the Earth.
 The crust of the Earth is broken into
many pieces called plates.
▪ Composed of mainly oxygen, silicon,
aluminum and small amounts of
other elements.
Mantle
 The
mantle is the layer below
the crust.
 It is the largest layer of the Earth.
 Consists of very dense rocks
which are rich in metals such as
magnesium and iron.
Outer Core
*
The core of the Earth is like a ball
of very hot metals.
 * The outer core is liquid.
 * The outer core is made up of
molten iron and nickels.
and is very dense.
Outer Core
Inner Core


* The inner core of the
Earth has temperatures
and pressures so great
that the metals are
squeezed together and
are not able to move.
* The inner core is a solid.
Today’s Activity
Make a model out of clay or using colour papers
and label the layers of the Earth.
•
• Inner layer: Red
• Outer layer: Orange
• Mantle: yellow
• Crust: brown
• Water: Blue
• Land: Green

Step by Step procedure
• Step 1:Roll all colors of play dough in to a ball.
Take your orange color and flatten it out into a
pancake shape.
•Step 2: Place the red ball (inner core) into the
center of the orange pancake you just made. Fold
over the edges, pinching and rounding things out
until you have an orange ball with a red ball in the
center.
Step by Step procedure cont…
• Step 3:Repeat the previous step with the yellow.
Flatten it out, then place the orange ball inside the
yellow pancake, folding over the edges and
rounding it out to make a ball.
•Step 4: Repeat and continue for the crust layer
and the water.
Step by Step procedure (cont…
• Step 5 :Break up bits of green to make land and
press it into your earth to represent the continents.
Smooth out the edges a bit to keep things round.
•Step
6: Cut the model into one fourth (1/4) using
a butter knife or a ruler (get help from an adult)
Label the layers of the Earth as shown below.
