-But why?
-I don't know.

Well, that's it then. We're done.
181
00:09:09,466 --> 00:09:12,553
What? No!
We just have to try something new.
182

Like what?
183
00:09:13,554 --> 00:09:16,056
Maybe the mouse needs to be slipperier.
184

Let's try again.

That's it. We failed.
194
00:09:42,833 --> 00:09:46,629
Well, my Great Aunt Rose says,
"The only way to fail is to quit."
195

We don't quit, we've got grit!
196

Okay, you're right. We don't quit.
197
00:09:51,759 --> 00:09:54,011
So, let's try something else.
198
00:09:54,094 --> 00:09:57,014
Something less mouse-y.
199
00:09:57,598 --> 00:10:00,434
The mouse is gone,
so we don't need the mousetrap.

That was awesome! Like magic.
210
00:10:29,713 --> 00:10:31,548
Or like science.
211
00:10:31,632 --> 00:10:35,511
Hey, maybe we can create a chain reaction
212
00:10:35,594 --> 00:10:38,931
that will let me unlock the door
from upstairs.
213
00:10:39,014 --> 00:10:42,267
Oh, yeah. We can totally do that.
214
00:10:42,351 --> 00:10:45,854
Cool. That way when you guys come over,
I can let you in.
215
00:10:45,938 --> 00:10:47,398
-Amazing!
-So cool!
216
00:10:47,481 --> 00:10:51,527
Arthur, I brought this super-sticky goo
as a fort-warming present.

00:10:51,610 --> 00:10:53,529
Sweet! Make yourself at home.
218
00:10:53,612 --> 00:10:54,530
Thanks, Arthur.
219
00:10:54,613 --> 00:10:56,365
-Got any questions?
-Yeah.
220
00:10:56,448 --> 00:10:59,952
If this fort was filled with owls
and they all flew at once,
221
00:11:00,035 --> 00:11:01,662
would it make the fort fly?
222
00:11:01,745 --> 00:11:04,164
-I don't know.
-If this was a space fort,
223
00:11:04,248 --> 00:11:06,583
-how much would we weigh?
-A space fort?

228
00:11:21,181 --> 00:11:23,392
Let's meet another scientist.
229
00:11:23,475 --> 00:11:24,309
Come on!
230
00:11:30,274 --> 00:11:32,776
[gentle music playing]
231
00:11:36,822 --> 00:11:40,742
Hi, my name is Keji Sojobi
and I'm an aerospace engineer,
232
00:11:40,826 --> 00:11:43,162
which means I get to design spacecraft.
233
00:11:43,787 --> 00:11:47,624
I'm gonna talk about the chain reactions
on the James Webb Space Telescope,
234
00:11:47,708 --> 00:11:49,918
-which I got to work on.
-[Ada] Cool!
235
00:11:50,002 --> 00:11:53,130
[Keji] When it gets out to where
it's going to be orbiting in space,
236
00:11:53,213 --> 00:11:56,383
the telescope will take pictures
of planets, stars, galaxies,
237
00:11:56,467 --> 00:11:59,970
and the pictures will help us
learn more about our universe.
238
00:12:00,053 --> 00:12:04,600
Hundreds of chain reactions have to happen
for all of it to go smoothly.
239
00:12:04,683 --> 00:12:07,478
A chain reaction is a series of events
240
00:12:07,561 --> 00:12:10,814
that happen because something else
happened before them.
241
00:12:10,898 --> 00:12:12,107
[Ada] Oh!
242
00:12:12,191 --> 00:12:14,735
I'm gonna use
these models that I made to show you.
243
00:12:14,818 --> 00:12:18,155
When the James Webb Space Telescope
is on Earth, it'll be folded up,
244
00:12:18,238 --> 00:12:19,656
looking something like this.
245
00:12:19,740 --> 00:12:23,327
We had to be able
to get from a folded-up position
246
00:12:23,410 --> 00:12:26,330
to a very open position in space.
247
00:12:26,413 --> 00:12:30,000
So after the rocket launches,
the telescope will separate
248
00:12:30,083 --> 00:12:33,128
and start to make its way
to its final destination.
249
00:12:33,212 --> 00:12:37,549
At that point, the chain reactions start
that will trigger the opening
250
00:12:37,633 --> 00:12:38,967
of this sun shield.
251
00:12:39,802 --> 00:12:44,807
And on and on and on, little triggers
fully open up the sun shield.
252
00:12:44,890 --> 00:12:48,644
And then the telescope will fully unfold.
253
00:12:48,727 --> 00:12:52,773
Our chain reactions are complete
and the telescope can do its job.
254
00:12:52,856 --> 00:12:53,857
[Ada] Yay!
255
00:12:53,941 --> 00:12:55,442
[gentle music playing]
256
00:12:57,486 --> 00:13:01,824
Chain reactions can happen really fast,
but can also last a long time.
257
00:13:01,907 --> 00:13:04,827
The chain reaction
of James Webb opening up
258
00:13:04,910 --> 00:13:06,662
is gonna be about 30 days.
259
00:13:06,745 --> 00:13:07,704
Fun fact.
260
00:13:07,788 --> 00:13:10,833
There are lots of human-made spacecraft
you can see from Earth
261
00:13:10,916 --> 00:13:12,876
when you look up at the night sky.
262
00:13:12,960 --> 00:13:16,463
If you see something that looks
like a star, but it's moving pretty fast,
263
00:13:16,547 --> 00:13:18,215
it's probably one of our satellites.
264
00:13:21,718 --> 00:13:24,555
Wasn't that cool? Science is the best!
265
00:13:28,016 --> 00:13:29,852
[Ada speaking]

[birds chirping]
267
00:13:32,396 --> 00:13:36,650
Is it me or does it always take longer
to fill a pool on a hot day?
268
00:13:36,733 --> 00:13:38,235
Oh, good question!
269
00:13:38,318 --> 00:13:41,697
And, does that mean a pool
would fill up faster on a cool day?
270
00:13:41,780 --> 00:13:45,492
Or if it were in the shade?
Or if we filled it with lemonade?

Why do you sound like a bird?
273
00:13:48,954 --> 00:13:51,790
Hey, that wasn't me.
Birds freak me out a little.
274
00:13:51,874 --> 00:13:54,376
Even when they look happy.
Like these ones do.
275

-[chirping]
-Hmm.
276
00:13:56,879 --> 00:14:01,383
That doesn't sound like happiness to me.
More like the opposite.
277
00:14:01,466 --> 00:14:03,176
Great observation, Rosie.
278
00:14:03,260 --> 00:14:05,762
Looks like these birds
aren't happy at all.
279
00:14:05,846 --> 00:14:07,556
They seem angry!

[chirping, squawking]
281
00:14:10,392 --> 00:14:15,772
Angry birds? Whoa! Mind blown.
[mimics explosion]
282
00:14:15,856 --> 00:14:18,233
That's way freakier than happy birds.
283
00:14:18,317 --> 00:14:19,901
Why would birds be angry?
284
00:14:19,985 --> 00:14:21,653
Excellent question.
285
00:14:21,737 --> 00:14:24,364
And I know someone
who can help us answer it.
286
00:14:24,448 --> 00:14:26,116
-Mom!
-[gasps]
287
00:14:26,199 --> 00:14:28,493
No need to holler. I'm right here.
288
00:14:28,577 --> 00:14:32,623
Sorry. Did you know our backyard
is filled with angry birds?
289
00:14:32,706 --> 00:14:36,001
Huh. I don't think I've ever seen
this many bickering birdies.
290
00:14:36,084 --> 00:14:40,505
There must be one, two…
twelve angry birds here!
291
00:14:40,589 --> 00:14:43,342
We're trying to figure out
what's making them so mad.
292
00:14:43,425 --> 00:14:47,304
Hmm. Here's a clue.
Their water feeder is empty.
293
00:14:47,387 --> 00:14:48,513
Ah-ha!
294
00:14:48,597 --> 00:14:52,225
They must be angry because
they don't have any water to drink.
295
00:14:52,309 --> 00:14:55,395
-So they're thirsty!
-Guess that answers our question
296
00:14:55,479 --> 00:14:59,024
about why they're angry,
but that doesn't answer the question
297
00:14:59,107 --> 00:15:03,153
of why there wasn't water in the feeder!
You always keep it full, Mom.
298
00:15:03,236 --> 00:15:07,699
I do. But yesterday, I had to run
an errand, so I asked your bro--
299
00:15:08,241 --> 00:15:09,242
Arthur!
300
00:15:09,326 --> 00:15:12,454
Yes, Mom? 76, 77, 78, 79…
301
00:15:14,373 --> 00:15:17,834
-What'd I do?
-It's what you didn't do. The bird feeder?
302
00:15:17,918 --> 00:15:19,878
Weren't you supposed
to fill it last night?
303
00:15:19,962 --> 00:15:21,421
I did! I promise!
304
00:15:21,505 --> 00:15:22,422
[cat meows]
305
00:15:23,757 --> 00:15:29,554
Mooshu Kitty! Someone has a bad habit
of drinking water from the birdie feeder.
306
00:15:29,638 --> 00:15:32,891
That's probably what happened.
Sorry, boo. My mistake.
307
00:15:32,974 --> 00:15:34,226
Mooshu!
308
00:15:34,309 --> 00:15:37,938
As for you,
you know what I said would happen
309
00:15:38,021 --> 00:15:40,524
if you drank from the feeder
one more time.
310
00:15:40,607 --> 00:15:43,318
-[ringing]
-Ooh, that's the call I'm expecting.
311
00:15:43,402 --> 00:15:45,153
What would happen?
312
00:15:45,654 --> 00:15:49,074
Oh, no! I think Mom's
gonna give Mooshu away.
313
00:15:49,157 --> 00:15:51,410
She already warned her
about the bird feeder.
314
00:15:51,493 --> 00:15:54,496
Plus, she wasn't a cat person
before Dad got her.
315
00:15:54,997 --> 00:15:56,832
-[meows]
-Mooshu!
316
00:15:56,915 --> 00:16:00,419
Mom! Mom! Mooshu's innocent.
She has to be.
317
00:16:00,502 --> 00:16:03,088
We'll find a way to prove it
and clear her name.
318
00:16:03,171 --> 00:16:06,174
[laughs] What? You mean like in a trial?
319
00:16:06,258 --> 00:16:10,846
Yep. Just like in a real courtroom.
You can be the judge, Mrs. Twist.
320
00:16:10,929 --> 00:16:15,475
Meet us in the living room,
I mean courtroom, in 30 minutes.
321
00:16:15,559 --> 00:16:19,062
-[laughs] Okay, okay.
-Don't do anything to Mooshu 'til then!
322
00:16:19,146 --> 00:16:22,065
-Do anything? What am I gonna do?
-[meows]

[Ada] Hmm.
324
00:16:26,111 --> 00:16:28,822
We're going to need
the scientific method for this.

"What happened to the birds' water?"
335
00:16:56,725 --> 00:16:59,186
-Unicorns drank it!
-[neighing]
336
00:16:59,269 --> 00:17:00,812
Maybe a unicorn,
337
00:17:00,896 --> 00:17:04,024
thirsty from chasing rainbows,
drank the water.
338
00:17:04,107 --> 00:17:08,528
But I'm disproving my own theory.
Unicorns like sparkling water.
339
00:17:08,612 --> 00:17:10,906
I think I've got it. Ants!
340
00:17:10,989 --> 00:17:13,950
Maybe a gazillion of them
built a tiny aqueduct.
341
00:17:14,034 --> 00:17:19,081
Yes! Now remind me how an aqua duck
is different from a regular duck?
342
00:17:19,164 --> 00:17:24,336
Aqueduct, not duck.
It's a bridge or canal that moves water.
343
00:17:24,419 --> 00:17:28,673
It'd be the itty-bittiest
architectural feat of all time!
344
00:17:28,757 --> 00:17:33,970
Hmm. Okay, so our hypothesis is
if Mooshu didn't drink the birdie water,
345
00:17:34,054 --> 00:17:35,889
then someone else must have.
346
00:17:35,972 --> 00:17:38,558
Hmm, I still say ants.
347
00:17:38,642 --> 00:17:41,228
So, like, what do we do now?
348
00:17:41,311 --> 00:17:44,147
We test our hypothesis
by looking for evidence.
349
00:17:44,231 --> 00:17:48,735
That's what scientists call facts
that prove or disprove their hypotheses.

Here's our first piece of evidence.
A paw print from the scene of the crime.
355
00:18:13,301 --> 00:18:16,847
Exactly the size of Mooshu's. [sighs]
356
00:18:16,930 --> 00:18:19,766
Are you sure
there aren't any ant prints there?
357
00:18:19,850 --> 00:18:21,726
Nope. Just cat prints.
358
00:18:21,810 --> 00:18:26,106
Okay, so maybe Mooshu was there,
but let's see what else we've got.
359
00:18:26,189 --> 00:18:28,692
-Here's Mooshu's water bowl.
-[meows]
360
00:18:28,775 --> 00:18:31,319
Empty.
Which means she was probably thirsty.
361
00:18:31,403 --> 00:18:34,447
Which would explain
why she'd want the water.

Boy, this is not looking good for Mooshu.

We still have this fur we found.
Let's look under the microscope.
365
00:18:43,415 --> 00:18:47,085
[gasps] It looks just like the fur
from Mooshu's paw.

is all pointing to one conclusion.

Mooshu's in cahoots with the ants!

00:19:01,016 --> 00:19:04,102
No. Mooshu drank the birdie water.

If we can't prove that Mooshu's innocent,

maybe we can at least prove
that she can behave.

Mooshu, isn't it true that even though
you've never been professionally trained,
398
00:20:21,721 --> 00:20:23,431
you can be very well-behaved?

And since you're

will you promise
to never drink from the bird feeder?

she can behave at all.

This is going horribly!
407
00:20:46,538 --> 00:20:49,499
Mooshu is being
the opposite of well-behaved.

00:20:49,582 --> 00:20:51,710

Yes, it may be true Mooshu Kitty
was at the scene of the crime,

00:21:40,425 --> 00:21:43,011
and, yes, she was thirsty,

Order! Order in the court.
Could you explain yourself, counselor?
433
00:21:59,444 --> 00:22:01,780
I propose that the water disappeared
434
00:22:01,863 --> 00:22:05,158
in a scientific process
called "evaporation."
435
00:22:05,241 --> 00:22:07,911
-[all gasp]
-Evaporation!
436
00:22:07,994 --> 00:22:12,082
-Wait, what's evaporation again?
-That's when water turns into gas.
437
00:22:13,374 --> 00:22:17,670
Then that gas mixes with the air,
making the water seem to disappear.
438
00:22:17,754 --> 00:22:21,049
This process can happen fast
on a hot, dry day,
439
00:22:21,132 --> 00:22:23,802
and when there's only
a teeny bit of water.
440
00:22:24,469 --> 00:22:26,679
Which brings me to our final witness.
441
00:22:27,222 --> 00:22:28,098
Arthur!
442
00:22:28,723 --> 00:22:29,557
Me?

00:22:31,559 --> 00:22:34,062
Now Arthur, wouldn't you say you were busy

Well, sure.
446
00:22:38,650 --> 00:22:42,320
So, it must have been really important
to fill the feeder fast.
447
00:22:42,403 --> 00:22:45,573
Fast? Well, I guess, but--
448
00:22:45,657 --> 00:22:47,367
The fastest way to fill the feeder
449
00:22:47,450 --> 00:22:51,830
would be to only put a teeny-weenie
bit of water in it, wouldn't you say?
450
00:22:55,208 --> 00:22:57,377
-Yeah!

452
00:22:58,670 --> 00:23:01,589
I only put a teeny bit of water
in the feeder!
453
00:23:01,673 --> 00:23:03,842
This proves our hypothesis.
454
00:23:03,925 --> 00:23:06,428
Something else could have happened
to the birdie water.
455
00:23:06,511 --> 00:23:10,223
Mooshu Kitty could be innocent.
I rest my case!
456
00:23:10,306 --> 00:23:11,641
-Yeah!
-Yes!
457
00:23:11,724 --> 00:23:14,102
Now you won't have to give Mooshu away!
458
00:23:14,185 --> 00:23:16,062
Give Mooshu away? What?
459
00:23:16,146 --> 00:23:18,481
You told Mooshu
that she knew what would happen
460
00:23:18,565 --> 00:23:20,692
if she drank from the bird feeder again.
461
00:23:20,775 --> 00:23:24,904
Yes, I'd give her a second bowl of water.
Outside!

Does anybody know
where I can find some water?
474
00:24:00,023 --> 00:24:03,818
Hi, my name is Naomi Fraga
and I'm a desert botanist,
475
00:24:03,902 --> 00:24:07,447
and today we're gonna talk
about evaporation in plants.
476
00:24:07,530 --> 00:24:09,991
-Let's check out some plants.
-[Ada] Let's go!
477
00:24:10,074 --> 00:24:14,370
We're here in the Mojave Desert
where it gets well over 100 degrees,
478
00:24:14,454 --> 00:24:16,831
and it also doesn't rain very much.
479
00:24:16,915 --> 00:24:22,712
These are actually two plants that live
in the same exact kind of environment,
480
00:24:22,795 --> 00:24:26,382
but they have different strategies
to hold on to their water.
481
00:24:26,466 --> 00:24:29,135
-[Ada] Whoa!
-This is the creosote bush.
482
00:24:29,219 --> 00:24:31,679
See, the leaves here are very small.
483
00:24:31,763 --> 00:24:35,975
That means there's fewer pores
on the leaf to lose water from.
484
00:24:36,059 --> 00:24:39,520
Just like we have pores in our skin
where we really sweat,
485
00:24:39,604 --> 00:24:43,066
plants have pores on their leaves
where water escapes,
486
00:24:43,149 --> 00:24:47,111
and when that water escapes,
it evaporates into the air.
487
00:24:47,695 --> 00:24:50,615
Then we have its very good friend,
the burro bush.
488
00:24:50,698 --> 00:24:51,616
-Hello!
-Hello!
489
00:24:51,699 --> 00:24:55,119
You might think it was dead,
but it's taking a nap.
490
00:24:55,203 --> 00:24:59,958
What we call a dormant phase.
It's lost its leaves for the summertime.
491
00:25:00,041 --> 00:25:03,336
Once it sees rain again,
it'll make new leaves.
492
00:25:03,419 --> 00:25:07,382
So these plants
have all these really cool adaptations
493
00:25:07,465 --> 00:25:10,134
for dealing with dry conditions.
494
00:25:10,218 --> 00:25:11,844
-[Ada] Fun fact!
-Fun fact!
495
00:25:11,928 --> 00:25:14,847
Did you know
that when your houseplant is wilting,
496
00:25:14,931 --> 00:25:17,976
it's because too much water
evaporated from the leaves?
497
00:25:18,059 --> 00:25:19,978
So if you see your plant wilting,
498
00:25:20,061 --> 00:25:22,605
give it a helping hand
and give it more water.
499
00:25:22,689 --> 00:25:24,691
Yay! Woo-hoo!
