- Hello!
Welcome to the Miami Science Museum.
I'm gonna be your guide today.
My name is Krista.
Penny and I are gonna give you each a wristband.
This wristband lets everyone in the museum know
that you're part of the field trip today.
Are we ready to have some fun?
- [Children] Yes!
- Let's go see the science museum.
This is our color shadow maker.
Did you know that mixing colors
can give you a new color?
(kids murmuring)
We have, projected on this big screen,
a red light, a green light and a blue light.
And if you go over there and make body movements
and shadows, you'll see lots of different colors.
Let's try it.
- [Penny] We're pink and then we're yellow
and now we're red.
I want to find the green.
Oh, well here's the sign of the colors we can make.
Someone make green! - I make green!
- [Penny] I see a green hand!
Whose hand is that?
Is that Miss Kirsta's hand?
Make blue... - I made it blue!
(kids all talking at once)
- [Penny] Yellow is next, who can make yellow?
- Yellow! - Me!
- I'm with (mumbles). - Yes you are!
- [Penny] Look, Ethan and Ken are mixing colors, watch.
(giggling)
Salmon is the next color,
that's like this turquoise color.
If we put all the colors together we make black.
Look, let's all stand in a line together.
- Go. - I made black!
- It's making black.
- This is called our downhill racer.
This activity is about motion.
With these discs, we can put them
on this slanted hill and have races.
Would you like to try? - Yes.
- [Group] Ready, set, go.
- Which one is going fastest?
- What's happening?
- This one here seems to be rolling fast.
- Why is this going fast?
- It's going fast, don't stop it,
we'll keep it going, there it goes.
- [Penny] Why do you think that one's faster?
(discs clicking)
- Yes!
- What else is different about the discs?
- This one has bigger wheels and this one has smaller one.
- Ready, all of us together.
- [Group] One, two, three...
(discs whirring)
(kids mumbling) - Maybe.
(thud of wood) (group cheering and clapping)
- And what's making it go down?
- This point, the little one, and it's got
the small wheels because it's helping to go faster.
- So if you notice, are all in the center.
Do you see how they're all in the middle?
And this one, they're all in the edge.
So let's see if that makes a difference
when we race it down.
- [Penny] Okay, only one push.
(discs whirring)
- There it goes. - What's happening?
- Mine is faster! - Why?
- Yes! - This exhibit
is called Lighten the Load.
It's a big lever.
Do you know what levers do?
(children all talking)
- I do, I do, because you (mumbles).
- Levers lift heavy loads.
For this lever, the load is going to be
on the bench and the way that you lift
will be how you pull on these ropes.
Depending on where you pull, it might make
the load heavier, it might make it more
or less difficult to lift up.
- Let's try it. - Let's try it.
- Let's try it, I'll be a load.
Who wants to be a load with me?
- I'm gonna pull it down and you guys
are gonna (laughs) help me (laughing).
(yelling)
So far!
You were really heavy on that rope.
Let's try this one, ready?
(yelling) It's so heavy.
Let's try this one, are you ready?
- Hold on - I can't even pull it down.
So what did we learn about the work that levers do?
- They push stuff.
- Well, they measure weight, that's true.
But they lift-- - Weight!
- Weight, exactly, they lift heavy loads.
That's what a lever does.
Which part of our lever made it easier
to pull and lift the load?
- First.
- [Penny] The first rope, right?
We had to pull it way, way down and use a lot
of our body energy, but was a little bit easier.
(gentle music) (eagle squeaking)
- This is our wildlife expert, Greta.
She's gonna show you two special birds today.
- How you doin' guys?
- [Children] Good.
- This is a bald eagle.
This is our national symbol and actually,
this bald eagle lives in south Florida.
So he's a Southern bald eagle.
Now, I want you guys to look at his feet.
(eagle squeaking) Come on, come on.
There you go.
You see how huge his feet are?
Do you know why his feet are so big?
- Why?
- Because he's big and he has to eat very, very big food.
What does he need to catch with those big feet.
- Catch fish?
- Not just fish, but a wiggling fish.
What does this bird have that you don't?
(children all talking)
- What? - Wing!
- Wings?
How come you don't have wings?
- We're not a bird and we don't
have beaks, only birds have them.
- That's right!
Eagles are so large and so heavy
that they need very big wings.
Look at that, wow!
Look at that. (wings rustling)
You are gonna love him.
(children cooing) Actually, her.
- [Child] It's a baby owl?
- No, she's not a baby owl.
- Could we hold her? - No, but you can
get really, really close to her.
- Look at her beak.
Do you see her beak?
- And she's got these little tufts.
Look at her tufts.
You know what her favorite food is?
- [Children] What?
- Bugs! - Ew, wow!
- But you know what's even better than just regular bugs?
Roaches. (children exclaiming)
She loves, loves to eat roaches.
You see, this is why her talons and her feet
are so little, 'cause all she does is needs to eat bugs.
These are the kind of bugs that she eats.
You see how little the bugs is?
- Where? - Let's see if she'll eat it.
- There's another one! - She's too interested
in everything else. - Could I hold it?
- There you go!
But that's why she doesn't need very big talons,
because all she has to do is eat bugs, all night long.
Why does she have small wings and
not big wings like the eagle, do you know?
- Because she's a small animal.
- Right.
- Tell me some things that are different about
the eagle and the owl, something that's different.
Kiana?
- The wings are little, the beak is not
the same size, the feet are little.
- That one's beak is small and the eagle's beak is big.
- That's right, why is that?
- Because that's a small animal and
the eagle's a big animal.
- Did you have a good time.
- [Children] Yes!
- Yes we did, let's go.
Say goodbye. - [All Together] Bye!
- Have a good day. - Thanks.
- Say goodbye. - Bye, bye.
- Bye owl. - Bye bald eagle.
