- Matter is all around us.

It is anything we see feel or that takes up space.

For example, water is matter.

You know what else is matter?

A ballon.

Watch this.

What do you think is gonna happen when I blow into it?

You think so?

Okay, let's see.

(air whooshing) You were right, it did get bigger.

(ballon squeals) (chuckles) When I blew into the balloon, the space inside became filled with air.

And guess what?

Air is matter too.

Because it takes up space in the balloon.

Now you didn't think I forgot to say it, did you?

Good morning, my dear sweet, beautiful, brilliant students of Arkansas.

Today we're going to investigate (jaunty music) and explore how matter can change.

Take a look at this ice.

What are some things that you notice about it?

I see that it's small.

It's kind of wet (chuckles) and it looks a little more sophisticated than a square because squares are flat, so it must be a cube.

Hmm, what else do I see?

Huh?

Yeah, I almost forgot about that.

It's clear and it is cold.

It's also a solid, which means that it keeps its shape and size.

I'm gonna just leave this over here and we'll come back to it in a little bit.

So let's explore some other things.

Look at this paper.

It's smooth, white and it's shaped like a rectangle.

Now, if I'll ball it up (paper rustling) and then try to flatten it back out, what changes do you see?

I can tell by touching it that the texture has changed.

At first it was smooth, now it feels sort of crinkly and rough.

But even though these things have changed about the paper, it's still paper.

Here, I have an apple.

It's red, it fits in my hand.

But if I slice it, then it becomes several different pieces and no longer one whole solid apple.

Even though these changes have occurred or have happened, it's still an apple.

Now, let's look back at the ice cubes we started with a little while ago.

Wait, where'd they go?

Did you come and get my ice cubes?

No?

Well, where are they?

They're not in the glass anymore.

How did it change?

What happened to it?

Are you telling me that they melted, that they got smaller and change from a solid to liquid?

(sighs) I wonder how can I change this liquid water back into a solid.

If you know, please tell me.

Hmm, ding, ding, ding, I got it.

Since the ice is just frozen or solid water, I can put it back in the freezer.

Now, (shushes) don't tell the other teachers that you gave me the answer.

I want them to think that I know what I'm doing.

Well, I have enjoyed learning about matter with you.

During this summer break, I hope you get the chance to eat lots of ice cream cones and popsicles.

You know, they're sort of like ice, so when you do eat it, take a second or two to notice how they change.

But don't look too long or too hard otherwise you'll make a mess and your clothes will end up eating the ice cream instead of you eating it.

Have a great rest of your day.

I'll see you later.
