[upbeat music] - Hi, friends.

My name is Cassandra and these are my helpers: - Noel.

- And Emory.

- And we're here today to do a fun science experiment with you.

Today we are going to talk a little bit about babies.

Do you have a baby at home, friends?

Or maybe in your neighborhood?

Did you know that you used to be a baby?

Noel and Emory, did you know that you used to be babies?

- Yes, but sometimes I forget.

- Sometimes I forget too.

[laughing] So we all used to be babies at one time.

And when we were babies, a lot of us might have worn something like this.

[soft upbeat music] Friends at home, do you know what this is?

Noel and Emory, what is this?

- It's a diaper.

- A diaper!

That's right.

Now, tell me something that you know about diapers.

- I know that sometimes babies wet themselves, so a diaper absorbs the water so the pants don't get wet.

- Oh, that's really good!

I also know that diapers come in different sizes because babies come in different sizes.

So today we have three sizes of diapers.

So we have a small diaper, like this one, for a small baby.

We have a medium diaper.

- Like this one.

- That Noel is going to show us.

- That I'm holding up.

- And large diapers that Emory will show us.

All right.

Now, let's make a hypothesis about these diapers.

A hypothesis is what you think is going to happen in our experiment.

Can you say that word?

Hypothesis.

- Hypothesis.

- Hypothesis.

- That's a hard word to say.

Let's try it again.

Hypothesis.

- Hypothesis.

- Hypothesis.

- Hypothesis.

- Hypothesis.

- Hypothesis.

- Oh, you got it.

Good job, friend.

So today we're going to make a hypothesis.

That means that's what we think is going to happen in our experiment.

So we have three different sizes of diapers.

We have some colored water so that our friends at home can see it.

What do we think is going to happen in our experiment?

- I think the bigger diapers, because they're for bigger babies, we'll be able to hold more water.

Then [indistinct], the small diaper will be able to hold less than the medium and large diaper.

- Oh, I think that's a really good hypothesis.

Do you agree with that, Emory?

- Yeah.

- What do you think, friends at home?

Do you agree that maybe this small diaper won't hold as much water as the medium or the large, and maybe the large one can hold the most?

Does that sound like a good hypothesis?

- Yeah, I think it sounds really good.

- Okay.

So should we do an experiment and try it out?

- I think we should.

- Yeah.

- Yeah?

Okay, so I'll go first and then maybe Noel, could you do the medium diaper?

- Yes.

- And Emory, could you do the large diaper?

Okay.

Now, friends at home, if you wanna try and experiment like this at home, make sure you put something on your table to absorb any spills that might happen just in case you spill any water or if the diaper might leak.

We will know that the diaper can't hold all the water as it leaks.

That means it will start spilling out in the diaper.

So I'm gonna give it a try with this small diaper.

I'm gonna take this one cup of water and I'm gonna pour it on the small diaper.

And let's see if it can hold all of this water.

Are you ready?

- Yeah.

- Are you ready, friends at home?

Let's see.

[upbeat music] Whoa.

It looks like it held it all.

- Look at that.

It's kind of, maybe can't hold it all, but it's pretty close.

Look, friend.

It's pretty close.

It looks like a li... Oh, a little bit's going.

Oh, it can't hold it all.

It was really close though, friend.

I thought it might hold it off, but it ended up leaking.

So we're gonna put a sad face for that one because it did leak.

It wasn't quite able to hold that whole cup of water.

Now, what do you think?

Should we try the medium diaper?

- I think we should.

- Do you think it can hold that whole cup of water?

- I think it can.

- Let's find out, friends at home.

Let's pour that cup of water on the medium diaper and let's see if it's able to hold all of that water.

[upbeat music continues] Hmm.

Okay, let's see.

Let's see, friends at home.

Hmm.

- It looks like it works.

- You think it worked?

- Yeah, I think it did.

- Do you think that?

Pick it up.

[gasping] It doesn't leak!

- Oh.

- No.

It leaks.

- Oh, it leaks a little bit.

- Just a tiny, tiny bit.

- A tiny bit.

- It absorbs better than- - Oh, what were you gonna say?

- It absorbs better than the small, but still doesn't absorb as well as I thought it would.

- Oh, wow.

So let's put a hmm, eh, it kind of works.

It kind of held that cup of water, but it leaked a little bit, but not as much as this one, right?

This one leaks more.

Okay, so should we try that large diaper?

- Yeah.

- Yeah?

- All right, so let me get some more water.

Do you think it will be ale to hold a whole cup of water?

- I'd think it might actually be able to hold a whole cup, and then like it will just spill not too much.

Like let's say there's a medium, it was like a middle ground here.

That's how much it would spill.

Okay, let's give it a try.

So go ahead.

[upbeat music] Pour it in.

Ooh.

- It might be able to hold it.

- Let's see.

Give it a second.

Okay.

We could pick it up.

- Wait.

- It's not leaking!

- Nope.

Not leaking.

- That one's not leaking at all!

Ooh.

So let's give that one a happy face.

Now, do we think it can hold another cup of water?

- Yeah.

- Do you think so, friends at home, could that large diaper hold another cup of water?

- I think it can.

- Do you think thumbs up or thumbs down?

- Thumbs up.

- Thumbs up.

- You think he can hold another cup?

Oh my goodness.

Should we try it, fiends at home?

Yeah?

Okay.

Emory, it's you.

Pour in another cup.

Let's see what happens.

[upbeat music continues] Pour it in.

Pour it in fast.

Okay.

Give it a second.

Give it a second to soak in.

What do you think?

- I don't think it's gonna spill.

- Oh, let's see, let's see.

Let's see.

- It's not spilling.

[Catherine gasping] - It worked!

It held two cups of water!

Let's put another smiley face.

- Should we try a third cup?

- Do you think it can hold a third cup?

- Yeah!

- Do you think so?

Oh my goodness.

Let's try it.

Let's see.

Let's see.

Oh, let's see what happens on the third cup.

Okay, Emory, remember, pour it in fast.

Good job.

Wow.

Do you see how puffy the diaper's getting?

- Yeah.

- Wow.

- I think it can, no.

- I don't think it can hold this one.

- 'Cause I don't think it's like submerging.

- It can't absorb the rest of the water.

- I don't think it can either.

- If not, let's try one.

- Okay.

Let's see, let's see.

- I think it's gonna spill.

- Yep.

- Oh!

It's leaking!

- It spilled a ton.

- It spilled a lot.

Okay, so that sounds like that gets a sad face for that one.

All right, let's put that over here.

So let's do a little recap.

What happened with the small diaper?

- It didn't hold any water sadly.

- It didn't hold that cup of water.

What happened with the medium?

- It was okay, but could be better.

It could hold whole cup.

It leaked just a little bit.

- Just leaked a little bit.

And what about that large diaper?

Emory, can you tell us about the large one?

- It hold two cups.

- It held two whole cups!

And then what happened on the third cup?

- It wasn't able to all submerge.

- It wasn't able to hold all of that third cup.

That's right.

Wow, friends at home.

So our hypothesis was right.

We thought that that large diaper would hold more water than the medium and the small.

And we also thought that this small would hold the least water.

So I think that we were right in our hypothesis.

Thank you for joining us for this experiment, friend.

If you would like to try this at home, make sure you ask a trusted adult to help you with some water, maybe getting some diapers, and make sure you protect your floor and your table from any spills.

Thank you so much for joining us, friend.

- Bye!

- Bye!
