• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.

-Nice neat notes that are legible and use indentations
when appropriate.
-Example of indent.
-Skip a line between topics
-Don’t skip pages
-Make visuals clear and well drawn.

• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.
• BLACK SLIDE: Pay attention, follow
directions, complete projects as described
and answer required questions neatly.

 New Area of Focus: Earth’s Interior.

• Learning about the earth’s interior. The
force behind our planet.

• Learning about the earth’s interior. The
force behind our planet.
“Come on.”
“This is ridiculous.”
“How can anybody know
what’s inside the earth?”

• We know the material of the interior of the
earth based on how P and S waves move
through the planet.

• Dynamic Earth Available sheets that follow
Part I for classwork if needed.

• Please Draw the following.

 Layers of the earth

• Layers of the earth

“Oh-no!” “We
are trying it one
more time.”

• Earth’s layers formed early in its long
history.
– (Archean Eon) Gravity pulled heavy elements
toward the middle.

The Big Idea
that the layers
formed 4.5
bya. deals with
is…

The Earth is 4.6
Billion Years Old
The layers formed very early

• Inner Core: Solid Iron and Nickel (Dense).

• Should you touch this? Why?
– It just came out of the fire.

• Answer! No, you will burn your hand.
– Dense metal such as iron takes a long time to
cool. Our Earth has been hot for a long time
because it’s one large hunk of hot metals.

• The spinning inner cores of solid and liquid
iron creates a giant electromagnetic field
around our planet.

• Electric Fields: The funky area near any
electrically-charged object.
– Replace electrostatic for funky.

• Activity! Drawing the earth’s EM Field.

EM Field refers to Electromagnetic

– Pass out a paper plate to everyone.
– Draw a Earth about the size of a golf ball in the
center.
– Spread iron filings all around the plate.

– From below, place a magnet beneath the earth and
record the magnetic field that is created.

– Sketch the magnetic field / directions of the iron
filings.

– Sketch the magnetic field / directions of the iron filings.

– Sketch the magnetic field / directions of the iron
filings.
Copy your sketch
into you science
journal and label
as the EM Field

• Electromagnetic field protects the earth
from charged particles.
– It also creates the Aurora borealis (Northern
Lights)

• Activity! Surgery

• Activity! Surgery on the earth.

– Each team of surgeons will perform surgery on
the earth.
– You need to use an incredibly sharp (plastic
knife) to make a series of incisions.
– Record a detailed sketch of…

Be prepared
to show the teacher /
memorize the layers

Note: The egg example is
missing a layer. Lets pretend
the yolk represents the inner
and outer core.
Draw in the layers with a
marker if you can. It’s tricky

 Inner Core: Solid Iron and Nickel (Dense).

 Outer Core: Liquid Iron and Nickel

 Mantle: Composed of Magnesium Silicates,
Iron, Calcium, Oxygen, Aluminum.

 Lithosphere: The outer part of the earth,
consisting of the crust and upper mantle.

• You can now complete this 5 Part Question
on the homework.

• Try and figure out the picture beneath the
boxes. Raise your hand when you think
you know.
– You only get one guess.

• This part of the PowerPoint roadmap is just one small
part of my Geology Topics Unit that I offer on TpT. This
unit includes…
• A six part 6,000 Slide PowerPoint Presentation / unit
roadmap full of activities, review questions, games, video
links, flashcards, materials list, and much more.
• A 18 bundled homework package, modified version, 19
pages of unit notes, 6 PowerPoint Review Games of
100+ slides each, videos, rubrics, and much more that
all chronologically follow the unit slideshow.
• This is a fantastic unit for any Earth Science Class.
