We were just about to head over to a nearby hill

to draw some of the beautiful flowers that we can see from there.

Squeaks went to grab his crayons, and he should be back any minute.

Squeaks is running a little low on his crayons.

We've been doing a lot of coloring lately, and it looks like

all of his crayons are kind of worn down.

It makes them a little hard to hold...and really hard to use!

So, he thinks it might be time to toss them out.

Instead of throwing these old crayons away...why don't we recycle them?

Recycling means taking something we would normally toss

into the trash and turning it into something new.

And it's a really simple way to help the Earth!

Recycling is a good way to help the Earth because of what happens

A lot of the stuff we throw into the garbage ends up

We use landfills to keep a community's garbage in one area.

Yep, landfill is another word for a dump.

Now, after a while, some of the trash that's in a landfill breaks down,

which means it crumbles into smaller pieces

and gets eaten by critters like worms that live in the dirt.

Food scraps like apple cores usually break down in a few months,

It takes 10 to 20 years for them to break down.

Cups and other things made out of Styrofoam can take hundreds of years!

And some things...like glass… basically don't break down at all.

They turn into smaller and smaller pieces, but they don't get eaten.

So they basically just stay there forever.

And that means garbage piles keep getting bigger and bigger!

The problem is… there's only so much room in every landfill.

When one gets full, we need to make a new one.

But when we make new landfills, we sometimes end up taking up space

where animals and plants are already living.

A lot of our trash — like paper, plastic, metal, and cans —

can get turned into new things that people can use again.

So when you put trash like this into a recycling bin…

you're doing something simple to help the Earth.

And I know a way we can recycle our leftover crayon pieces!

Okay, Squeaks… we're going to keep our old crayons out of the landfill

If you decide that you want to try this…

you definitely want to get some help from a grownup.

You'll only need two things: your old crayons,

and some kind of bakeable mold to shape the new crayons in.

Okay, the first thing we need to do is take off

any paper that might be around the crayons.

And now, we're ready to put them in our mold.

We need to make sure that the mold can take a little heat…

because we're going to put it in the oven set to a low temperature:

like 80°C, or for our US oven, 170° Fahrenheit.

Let's make some that are all one color… and some that are two colors.

And now, we'll need to wait for 8 minutes or so.

While we wait...I have a question for you!

What do you think is going to happen when we heat the crayons?

I'll give you a hint: what happens to ice when it gets warmer?

It changes from a solid piece of ice that we can hold in our hand…

...into liquid water that's easier to hold in a cup.

Both the ice in our hand and the water in the cup are made

out of the same stuff—water—they just look different.

Well, wax, the stuff that makes up crayons, also melts

when it gets too warm—which is why we put those crayon bits in a mold,

which will act like a cup when they turn into a liquid.

There is one big difference between ice and our crayons, though—

it takes a lot more heat to melt wax than it does to melt ice!

Which is a good thing, otherwise crayons would melt in your hand!

They're still the same color they were when we put them in

the mold...but they definitely look different than they did

Now, we'll let them cool...and see what happens.

Let's guess what will happen while we wait for them to cool!

What happens if we take water from melted ice
