[upbeat cheerful music] - Hi.

- Hey, question, what planet do we live on?

We live on Earth.

- Earth.

- Yes, Earth is our home.

Hey, let's take a moment and let's look at this web I have right here.

Earth.

- Earth.

- Earth is our home.

Earth's surface is mainly water.

You see, the green is land and the blue is water.

And there's a whole lot of blue, right Sahil?

- Yeah.

- Earth is over 4.5 billion years old.

- Yeah.

- That's old.

- Yeah.

- Earth rotates at around 1000 miles an hour, woo.

Earth is the third closest planet to the sun.

Earth is our home.

Do you think it's important that we take care of our home?

- Yeah.

- It's very important that we take care of our home.

We have to make sure that it's clean.

- If our home is a little bit dirty, then [indistinct] and Elton come.

- Oh yeah, that's right.

- And do they clean it up?

- Yeah.

- Yeah.

So how about air pollution?

Do you know what pollution is?

- Yeah.

- What's pollution?

What's an example of pollution?

Anything that causes harm to our Earth, that is pollution like smoke.

- Wait, like that Earth?

- Yes, smoke and gas.

Do you wanna know what we're gonna do today?

We're gonna make something that's gonna help clean the earth.

Do you wanna do that?

- Yeah.

- And our friends at home, they can do it at home as well, okay?

- Yeah, but I dunno how to do.

- I'm gonna show you, okay?

We're gonna make something.

- I don't have that at home.

- What at home?

- This.

- Oh, well we don't need this for our activity.

- No.

- [Krystal] We're going to make something using the materials we have here at the table, okay?

Do you have paper plates at home?

- [Sahil] I think I do.

- Okay, do you have crayons at home?

- Yeah.

- Do you have string at home?

- Yeah.

- Yes, okay.

Do you have scissors at home?

- Yeah, I have only grownup scissors.

- Oh, well that's okay, that'll work.

And look, we also have some petroleum jelly.

You know what this is used for?

It's used to heal your skin.

- That's for like rubbing.

- Yeah, you rub it on your skin.

And also if you have like dried chapped lips, you can put it on your lips.

Helps keep you moisturized.

- Or all over your skin.

- If you need it.

We're gonna make a pollution catcher.

- And that?

Well, do you know what this is called?

- Yeah.

- It's a hole puncher.

- Hole puncher.

- Yeah, so we use this to poke holes.

But friends at home, if you don't have a hole puncher, just use a pencil to poke a hole, okay?

So this is what we're gonna do.

We're gonna take a paper plate.

- That looks like something for our nails.

- It does look like a nail clipper.

Yeah, you're right, it does.

So look, we're gonna take your paper plate.

First thing, use the hole puncher.

Poke a hole.

- Poke a hole.

- And at home, if you do not have a hole puncher, take a pencil or a pen and just poke a hole, right?

- Yeah.

- Simple, okay?

And now next, I want you to think of Earth.

Think of a beautiful clean Earth.

And when I think of the Earth, I think of the ocean.

So on one side, take stickers if you'd like, or if you don't have any stickers, use some crayons and some markers and draw a picture on one side of the paper plate.

- I think I have so many stickers at my home.

- Oh, perfect, so Sahil and I, on our paper plates, we have the ocean, and we put some ocean animal stickers.

And Sahil, we're gonna remember the first step, poking the hole.

So we're gonna poke holes, one into mine.

Would you like to poke yours?

- Yeah.

- I'll stick it in for you, and we can press together.

Press, there you go, good job.

- Yeah.

- Okay, perfect.

At home, remember, take your time, make your design, don't rush.

Okay, so we have that.

And now, what we're gonna do is we're going to turn it over and not at the side where we did our design.

On the other side of the paper plate, you'll take your petroleum jelly, which you can find this at any drug store or any corner store.

Take a scoop of this jelly and you are gonna put it on the plate like this and rub it around the plate, just like that.

All right, Sahil, just like that.

Do you see how I tap it like this?

- Yeah.

- So that I can get the petroleum jelly on the plate?

And then I use the bottom of the spoon to spread, okay?

- Yeah.

- So scoop up some- - Can you do it over here?

If you like, you can.

- Oh yeah.

- Okay, so Sahil's question was if he can place the Vaseline over here?

And you can, you can place it around the plate if you'd like.

I like to start in the middle and then I spread it out.

Spread, spread, spread, spread, spread.

Good job, Sahil.

And then you can spread it, yeah.

And if you'd like, you can turn it over this way, the bottom of the spoon so it's easier to spread.

You see that?

Get a little around there.

Good job, Sahil.

We'll see at home.

Look at that.

And now, I'm gonna take my spoon.

I'm gonna put it back in here.

Here, Sahil will put it back in there, perfect.

And then we're going to now take a piece of string.

And what do you think I'm gonna do with the string?

- Put it in the hole.

- That's right, you're so smart.

You are gonna take the string, put it through the hole, and now, I'm gonna tie a knot like this.

And look friends at home, now I can hang this somewhere.

Now, what you can do is hang it outside somewhere.

Hang it on a tree if you can on the branch, maybe hang it- - Or on your home.

- Yeah, well you know what?

You can, if you wanted to check the air, the air quality inside your home, but I would suggest you putting it outside so you can see the air quality outside.

And you know what it's going to do?

All of the pollutants that are in the air, although we can't see them, they're there.

And this is gonna trap 'em.

They're going to get stuck.

They're gonna stick to the petroleum jelly.

Leave it hanging for a week, maybe two weeks, maybe a month, and then get a magnifying glass and closely observe, look at all of the pollutants that you caught.

Look, let me show you something right now.

Sahil and mine, looks so beautiful and so clean.

I did this a week ago, Sahil.

And I hung it outside of our school.

Beautiful, clean Earth on one side.

Look at all of the pollutants.

- Does that go into space?

- It goes in the air, and we breathe this in.

- Or when it's in my tummy.

- Yeah, and when you breathe in pollutants, you know what can happen?

We can get sick.

- Yeah.

- Yeah, so that's not good.

- We don't wanna be sick.

- That's right, so friends at home, let's work together and let's clean our Earth.
