Oh, I want to see!
It's a rock.
An orange rock.
I wonder what kind of rocket is?
[sniffs] Okay.
-Jeff, what are you doing?
-Oh, you can learn a lot by closely interacting with a rock.
The rocks here in Colorado they often have this orangish co -because they are made of— -Sandstone Sandstone, haha [sniffs] Yep.
Definitely sandstone.
Cool!
Hey, look over there.
Oh, that looks pretty big.
I wonder if anything lives in that den.
An animal habitat.
Let's go check it out.
I'm not so sure we should go in there, Sean.
Paige, do you think it's a good idea to go into a habitat of an anima Where's Paige?
Okay, Jeff, do you think it's a good idea to go into a habitat of an animal?
Well, what do you think?
Let's ask the kids.

Is it a good to go into an animal's habitat?
I say risk it and go inside.
Let's talk to another one of our experts for more qualified information.
Drew and Ryan, what animal noise would you make for an animal that lives in a cave?
[soft growls] [howling] If I was trying to warn someone not to go into that habitat, how would I warn them en espangol?
Espera.
No!
No vayas ahi.
What if you were a salsa dancing?
That would be okay.

Yeah, don't eat that cute bunny.
Wait, are you gonna eat, us?
I don't want to eat you.

I enjoy an insect or a bird for a snack.
I'm definitely going to enjoy this bunny later.
Soy un carnivora [rawr] A carnivore, a meat eater.
Don't you know anything about the food web?
Food web?
Well, if you were a plant.
Una planta I'm a plant!
I'm making my own food.
Using energy from the sun.
Carbon dioxide from your breath and... water!
Then that makes you a producer.
Un productor.
And if you were a rabbit.
Un conejo.
Hah!
I'm a bunny!
An herbivore, a plant eater!
I like to nibble on the green green plants.
Sorry Shaun.
Jeff.
Jeff.
Jeff, we're friends!
We're friends!
That makes you and herbivore, un herbivoro.
and herbivores only eat plants.
[crying] And I am a carnivore, a meat eater.

[rawr] Speaking of... Where did that bunny go?
What do you eat?
Human?
Well, I eat meat and plants.
-Oh -So what am I?
That makes you an omnivore Un omnivoro Sweet.
I'm an omnivore.
No matter what we eat, we're all connected by the energy of the sun!
Thanks sun!
You're welcome.
El Sol here, The sun.
Source of energy for all life.
Way down there on planet Earth.
Kind of a big deal.
Is it hot up here, or is it just me?
Well, I'm so glad you're not going to eat us.
I was really scared.
[Scoffs] You were scared.
This is my home.
I was just coming here to take a little rest, and then, We're sorry we scared you.
This is my habitat, I live here, I eat here, I sleep here, I groom myself, and I raised my kittens.
[Meows] So when we're out in nature or in our neighborhood?
We're guests of the plants and animals that live here.
Thank you.
Respecting the life all around us means understanding.
Understanding what it's like to be a bobcat.
If you would like to be a bobcat with us, you can.
Get out your claws, sharpen them on a log in front of you like this.
Afilen sus garras.
Las garras, arriba.
Las garras, abajo.
Claws up high and claws down low.
Show me your sharp teeth.

It's floating.
-I wonder why -I still have this orange rock.
Let's see what happens when I throw it into the water.
We won't be seeing that again anytime soon.
It sank!
It's almost like a game.
Figuring out which things sink o Float.
Density.
Hello, it's time for everyone's favorite game show.
Sink or float?
It's a game show in which we take everyday household objects, drop them into a tub of water and find out whether or not they will sink or float!
First up today we have a stick.
We'll find out what happens in three, two, one.
It floats.
Wow!
Next up we've got a spoon.
Let's see in 3 2 1 It sinks!
Hey these objects the stick and the spoon are relatively the same size, but one floats and the other sinks.
What's up with that?
♪ density ♪ Too the lab!
Oh, hello.
Hello.
Welcome to the lab.
So glad you're here.
Professor Erlenmeyer, PhD in accidental explosions.
My latest invention turns bread into toast.
And I'm Professor Serious.
Here to help.
Professor Serious, Colorado's least smiley scientist.
No smiling.
gitchy, gitchy goo!
And I am Professor Bunsen.
Professor Bunsen.
She's been heating things up in the lab for quite some time.
So glad you're here to Bunsi-poo Together, we're a dream team.
Our greatest combined discovery was finding out that you could not sleep with the other side of the room.
It only works one way.
We digress.
Where were we?
Yes.
Sticks and spoons and sinking.
It's time to talk about density.
Everyone say density.
Density.
How about with a little bit more zaaaz.
Density.
Density!
Some things sink, others float.
And it's because of density.
There are molecules everywhere.
The whole world is made up of them.
They are here, over here, over there, right here and further away.
Everywhere.
Molecules are everywhere and some are packed tightly.
Everyone try this.
Make yourselves tight.
Squeeze it tighter.
Tighter.
You're very dense.
You're sinking.
Ohhhhhhh!
Other molecules are loose, flowing molecules.
Try this like a leaf floating in the wind.
Molecules are floating.
Uh oh No song break?
Magnificent.
I do believe I've got it.
It's all about the molecular structure.
How much stuff is packed into a Or not packed in like a leaf.
Wait, why can't we see them?
Oh, right.
Because they're invisible.

Deeeeense.
Ooh ah ah, Ooh Ooh ah ah We're Hiking Somos exploradores Ooh ah ah, Ooh Ooh ah ah We're Hiking Oh, wait.
What do we do with all this?
Let's ask the compost bin Sort the trash!
Hola, compost bin!
Hello, Rangers.
What do you have for me today?
Oh, we have some paper, an orange peel and granola wrapper.
You can recycle the paper and the wrapper goes in the trash.
Only food scraps for me please.
Please bring it on!
That's the good stuff.
Oh, he looks so happy.
Thank you.
Good to see ya!
It's time to end.
Sometimes I feel a little sad when things come to an end.
It's okay to feel sad.
That means what you're feeling is important.
Now feel your feet on the ground.
Sit up straight with your head to the sky.
Take a deep breath in.
Let it go.
See you later.
We can't wait to play, learn and sing with you all next time.
Now turn off the show.
There's so much to explore.
