Rocks: Hard, Soft, Smooth, and Rough

Hi, boys and girls today I am going to read

you. Ah, story that she'll need Teoh.

Actually, um, you hear about on and to continue with

our energy.

Sorry, Our earth.

It's features.

Um we're going to keep looking at our observations and

use the tools that we have around our home and

in your neighbor it.

So let's just get started.

The book that I am going to read to you

is called Rocks.

Hard, Soft, Smooth Embera, written by Natalie Um Krosinsky and

illustrated by Matthew Job.

The story of rocks See the rock at your feet

Pick it up.

Hold in your hands Is it smooth and sparkly as

it's soft and sandy?

Is it marked with shape of a shell?

Look closely at Iraq and you can learn its story

Fun Fact.

Some rocks are four billion years old.

That's four 000000000 years.

Four billion years old.

Think of all the stories.

Rocks. Ah, lot of things could happen to rocks they

can crack.

They can break into a moving tiny pieces.

They can be pressed or squeezed together.

Rocks can even melt pools of hot melted rock high

deep inside the Earth, but that the ground underneath oceans,

fields, beaches and forced is rock.

You might see specks or Lord you stripes of different

colors in Nor Rock thesis backs and stripes are different

crudes of minerals.

Minerals are the basic building blocks of rocks.

Rubies and diamonds are minerals.

People carved them into jams that sparkle in emphasis and

rings. But in fact, diamonds are the hardest natural things

in the world.

Diamonds are so strong they can even cut through steel.

There's a picture of a ruby, and this is a

picture off a diamond.

Igneous rocks.

Rocks form in three ways.

In the first way, melted rock bubbles up from inside

the earth.

Then it cools down and becomes hard.

Igneous rock If you're rock looks like black less and

make the obsidian.

Obsidian is an igneous rock that bubbled up from inside

the Earth and cooled off above ground.

Rough, freckled brand is an igneous rock that cooled on

your graph.

Funfair. Native Americans once carved obsidian into sharp knives at

arrowheads. Sparkled granite is often used for gravestones and countertops,

so here's a picture of enough city in and the

sons a picture of a grant.

Sedimentary rocks, racks also for months and and other natural

things air squeezed together on.

So they turn, huh?

This kind of rock is called sedimentary rock.

These rocks are a little softer than igneous rocks.

Plants, animal bodies, shells, Sam and chips of other rocks

pile up on the bottom of oceans and rivers.

This mixture is called seven it as the mixture plaza.

It gets heavy on the settlement at the bottom gets

squeezed together, it turns harder and Harvard, until it is

rock sedimentary rock.

This rock can take millions of years to form.

Laugh at.

In cliffs and canyons, you can sometimes see different layers

of sediment suddenly years or is tallest skyscrapers?

If you see grants of crumbly sand in your rock,

it might be sandstone.

Dull and greedy.

Sandstone is a sedimentary rock made of sand red, brown,

green or yellow fun.

Fact. Some Native Americans wants lived in homes in sandstone

cliffs. If you see squiggles and boss from little shells

and skeletons in your rack, it might be limestone limestone.

Another sedimentary rock is made of shells from ocean animals

that lived a long time ago.

One fact.

Today, people use limestone to make side axe and buildings.

Some sedimentary rex tell stories about the past.

Stores have forgot, enforced and vanished sees they tell tales

of creatures that swam.

Still, leather or corrupt fossils are made from plants and

animals that die thousands or millions of years ago, the

plants and animals became buried in layers of settlement.

Over time, they turned into rock fun.

Fact. Scientists learned about dinosaurs by starting possible so foams

T as nest and droppings.

Each fossil is a clue.

For example, the shape of a dinosaur tooth can show

whether dancer eight, please or plants metamorphic drops.

The third kind of rock is made from other rocks.

He in pressure deep inside the earth, can change rocks

from one kind to another.

Metamorphic rocks can come from igneous or sedimentary rough.

After time, the heat and pressure can even turn a

metamorphic rock into a new metamorphic rock.

If you're rockets heart and full of colorful swirls, it

might be marvel.

Marvel is in that amorphous crock made from limestone that

cooked inside the earth.

But in fact, artist carved marble into statues that tell

their own special stories and that's a picture of a

marble. Rocks are all around rock.

Slide your feet or sit silently by the river's edge.

Rocks make a giant cliff a magnificent building or a

grand sculpture, rocks hanging around your neck or sparkle on

your fingers.

Look closely at um, what stories do these rats town

and here's a chart of rocks, and I'm not sure

you can make out what each of them says.

But going back to the illustration of obsidian.

This is the kind of rock is igneous colors as

its shiny black.

What it feels like it's hard and glassy at union

uses. Um, I'm sorry.

Back track uses are Indian.

Arrow has granite is igneous.

The colors are mixed of gray, white, pink or red.

It's hard and rough, and gravestones, buildings and monuments are

what granite could be turned into.

Sandstone. You have sedimentary.

It's rad, brown, green or yellow.

They're grainy and calmly and singing stone are used to

make Hilton's limestone sedimentary rocks tan.

Greater yellow can be soft and chalky or course and

heart. They can be turned into buildings and sidewalks.

Marble metamorphic, made from limestone, white or gray, often with

black red or green stripes hard and cold can be

grainy on the product that marble can turn into is

statues and buildings.

So boys and girls But I'd like you to do

is to collect 10 rocks from around your neighborhood or

around your house.

I would like you to find different colors, shapes and

sizes, and I have here.

Let's see if this works a physical properties.

So new word that I'm introducing you is the characteristics

of what you could find with rocks.

So as you have heard in the story, I have

talked about different colors, shapes and sizes.

I would like you to collect 10 rocks and line

a Muppet Truth table and then make different groups into

them, using the physical property poster that I have listed

here. So there is our different groups.

Can you guess which tracks might be igneous, sedimentary or

metamorphic? And this chart should help you have some ideal

in making your assignment for this Sweets Choice Board that

is going to be given for the next two weeks.

Um, refer to this video if I need it.

I am looking for the different sizes.

Maybe he might find patterns that you know it, ISS.

I would like you to illustrate that.

And, um, you will notice that in shine like that

is shiny is a dull visit.

Lackluster. There's the different color words texture I've described as

bumpy, smooth, rough, soft, hard or pointy.

The different shapes and perhaps the wait.

How does it feel?

Um, isn't light as a feather?

Is it heavy if you're carrying like a heavier weight?

This poster here, this anchor chart is a way to

help you recognize what kind of rocks they are.

So is it igneous made when it's like with all

volcano hot magma cools cooked quickly.

Is it sedimentary?

Are there lots of layers?

Um, that's being squished together, like under the ocean.

Or is it metamorphic?

Do you think that it may have changed by pressure,

heat and used to being igneous or sedimentary on your

choice board?

I have extra links for you to actually figure out

if you need to refer to it.

Um, and if you're not able to access the video,

those links are brought up in there as well.

So happy hunting.

And I'm looking forward to seeing what you put on

your tryst, boy.

Sorry. Your story before.

All right, Have fun
