CATALYST—HW DUE TOMORROW1. Where do hot things go?2. How do hot molecules move?3. How far are hot molecules apart?4. Are hot molecules like a solid liquid or
gas?5. Where do cold things go?6. Are cold things like a solid liquid or
gas?7. Why do cold things do that?8. What is density?9. What is the formula for density?

PLAY DOUGH EARTH! Every set of four will get one Earth and
one piece of dental floss One person will cut the Earth in half
with dental floss—two partners will share one half and two partners will share the other half
Look at the layers of the Earth—see if you and your partner can name all of them.

HOW MANY LAYERS ARE THERE? There are four
layers of the Earth:- the crust- the mantle- the outer core- the inner core
![Page 5: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/5.jpg)
DRAW AND LABEL THE EARTH YOU SEE IN YOUR HAND
![Page 6: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/6.jpg)
CRUST: The crust is the
thinnest outer layer of the
Earth Connection Think,
Pair, Share: If it is the top layer do you think it is the densest or least dense layer?
![Page 7: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/7.jpg)
WHAT COULD WE COMPARE THE CRUST OF THE EARTH TO?
Example: It is similar to the peel of an apple in the sense that it is thin and covers the outside of the Earth
Think Pair Share—any other ideas?
![Page 8: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/8.jpg)
WHAT DOES CRUST LOOK LIKE?
Anywhere you can see rock, you are seeing the crust of the Earth!!!
A lot of the crust is hard to see because it is covered by soil, rock and water
![Page 9: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/9.jpg)
CRUST IS UNDER THE OCEANS AND ON THE LAND:
Crust is thicker beneath continents Crust is thinner beneath oceans or rivers Why does that make sense?
Mountains are parts of the crust that stick out (made of rock)
![Page 10: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/10.jpg)
CRUST IS MOSTLY:
OXYGEN---- 47%
SILICON– 28%

LET’S GO DEEPER INTO THE EARTH Peel Back your Play dough Layer! Now what layer are we on?
![Page 13: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/13.jpg)
MANTLE: The mantle
is the thickest layer
located in the middle of the Earth
![Page 14: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/14.jpg)
WHAT COULD WE COMPARE THE MANTLE OF THE EARTH TO?
Example: It is similar to the white part of an apple in the sense that it is the thickest part
Think Pair Share—any other ideas?
![Page 15: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/15.jpg)
WHAT DOES MANTLE LOOK LIKE?
The Mantle is HOT
At this temperature the rock begins to melt making the Mantle thick and oozy!
Mantle is what bursts out of volcanoes
![Page 16: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/16.jpg)

LET’S GO DEEPER INTO THE EARTH Peel Back your Play dough Layer! Now what layer are we on?
![Page 18: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/18.jpg)
CORE: The core is the
hottest located in the center
of the Earth Connection Think,
Pair, Share: If it is the inner layer do you think it is the densest or least dense layer?
![Page 19: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/19.jpg)
WHAT COULD WE COMPARE THE CORE OF THE EARTH TO?
Example: It is similar to the seeds or core of an apple in the sense that it is the center and the hardest/densest part.
Think Pair Share—any other ideas?
![Page 20: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/20.jpg)
WHAT DOES CORE LOOK LIKE?
2 layers:Liquid outer core
Solid inner core—hard, dense center– so much pressure that despite the hot temperature that would melt the rocks it stays solid.
![Page 21: Catalyst—HW DUE TOMORROW](https://reader036.fdocuments.us/reader036/viewer/2022062520/56816225550346895dd256ba/html5/thumbnails/21.jpg)
THE CORE IS MOSTLY:
IRON----
NICKEL---
