00:00:03,898 --> 00:00:05,826
(man laughing)

00:00:05,826 --> 00:00:06,966
- [Man] Beautiful.

00:00:06,966 --> 00:00:10,133
(bright upbeat music)

5
00:00:14,548 --> 00:00:15,966
(murmuring)

6
00:00:15,966 --> 00:00:16,866
- Yeah.

7
00:00:16,866 --> 00:00:17,699

00:00:17,699 --> 00:00:20,866

(bright upbeat music)

10
00:00:35,130 --> 00:00:38,560
- Hi and welcome back to Storytime Science

11
00:00:38,560 --> 00:00:40,600
at the Exploratorium.

12
00:00:40,600 --> 00:00:44,490
Today's episode is Bubble Cells.

13
00:00:44,490 --> 00:00:47,350
That's gonna mean a lot more
once we get to the activity,

14
00:00:47,350 --> 00:00:49,200
but first, we're gonna read a book.

15
00:00:49,200 --> 00:00:51,830
And today's book, one of my favorites,

16
00:00:51,830 --> 00:00:55,180
is "Ada Twist Scientist."

17
00:00:55,180 --> 00:00:56,768
So let's get started.

18
00:00:56,768 --> 00:00:58,960
(bright upbeat music)

19
00:00:58,960 --> 00:01:02,970
Today's book is "Ada Twist Scientist"

20
00:01:02,970 --> 00:01:06,580
by Andrea Beaty and David Roberts.

21
00:01:06,580 --> 00:01:08,650
This book isn't specifically

22
00:01:08,650 --> 00:01:12,000
about bubble cells, but
this is a really good story

23
00:01:12,000 --> 00:01:14,770
about a very curious young woman.

24
00:01:14,770 --> 00:01:19,060
And she's probably gonna be a
scientist when she grows up.

25
00:01:19,060 --> 00:01:21,783
She's kind of already a scientist.

26
00:01:23,040 --> 00:01:28,040
Ada Marie, Ada Marie said
not a word till the day

27
00:01:29,130 --> 00:01:31,250
she turned three.

28
00:01:31,250 --> 00:01:36,250
She bounced in her crib and
looked all around observing

29
00:01:36,730 --> 00:01:39,970
the world, but not making a sound.

30
00:01:39,970 --> 00:01:43,480
She learned how to climb
and made her big break

31
00:01:43,480 --> 00:01:48,030
with a trail of chaos left in her wake.

32
00:01:48,030 --> 00:01:51,860
She ran through the
day, chasing each sound

33
00:01:51,860 --> 00:01:56,860
and sight and didn't slow down
till she conked out at night.

34
00:01:58,680 --> 00:02:00,980
It's a picture of her brother here too.

35
00:02:00,980 --> 00:02:05,725
Her parents were frazzled,
but tried not to freak

36
00:02:05,725 --> 00:02:10,725
as Ada grew bigger and
still did not speak.

37
00:02:11,760 --> 00:02:16,760
Clearly, young Ada with lots in her head

38
00:02:16,820 --> 00:02:19,090
would have something to say

39
00:02:19,090 --> 00:02:21,420
when it ought to be said.

40
00:02:21,420 --> 00:02:25,930
That's just what happened
when Ada turned three.

41
00:02:25,930 --> 00:02:30,250
She tore through the house
on a fact finding spree

42
00:02:30,250 --> 00:02:34,370
and climbed up the clock
just as high as she could.

43
00:02:34,370 --> 00:02:36,670
Her parents yelled, "Stop!"

44
00:02:36,670 --> 00:02:38,943
As all good parents would.

45
00:02:39,910 --> 00:02:44,760
Ada's chin quivered, but she did not cry.

46
00:02:44,760 --> 00:02:46,618
She took a deep breath

47
00:02:46,618 --> 00:02:50,293
and she simply asked, "Why?

48
00:02:51,927 --> 00:02:53,677
"Why does it tick?

49
00:02:53,677 --> 00:02:55,757
"And why does it tock?

50
00:02:55,757 --> 00:02:59,557
"Why don't we call it
a granddaughter clock?

51
00:02:59,557 --> 00:03:02,967
"Why are there pointy
things stuck to a rose?

52
00:03:02,967 --> 00:03:06,447
"Why are there hairs up
inside of your nose?"

53
00:03:07,689 --> 00:03:12,689
She started with why and
then what, how, and when.

54
00:03:12,800 --> 00:03:17,670
By bed time, she came
back to why once again.

55
00:03:17,670 --> 00:03:22,670
She drifted to sleep as
her dazed parents smiled

56
00:03:22,880 --> 00:03:27,870
at the curious thoughts
of their curious child

57
00:03:27,870 --> 00:03:32,810
who wanted to know what
the world was about.

58
00:03:32,810 --> 00:03:37,287
They kissed her and whispered,
"You'll figure it out."

59
00:03:38,590 --> 00:03:43,180
Her parents kept up with
their high flying kid

60
00:03:43,180 --> 00:03:48,180
whose questions and chaos
both grew as she did on there.

61
00:03:49,279 --> 00:03:50,607
And there're all these
things on this page,

62
00:03:50,607 --> 00:03:51,537
"What is it for?

63
00:03:51,537 --> 00:03:52,537
"Will it be the same?

64
00:03:52,537 --> 00:03:53,370
"What if?

65
00:03:53,370 --> 00:03:54,618
"Why?

66
00:03:54,618 --> 00:03:55,451
"Will it?

67
00:03:55,451 --> 00:03:56,284
"When will it?

68
00:03:56,284 --> 00:03:57,117
"When?

69
00:03:57,117 --> 00:03:57,950
"What?

70
00:03:57,950 --> 00:03:58,783
"What does it do?

71
00:03:58,783 --> 00:03:59,616
"Why won't it?

72
00:03:59,616 --> 00:04:00,449
"Why does it?

73
00:04:00,449 --> 00:04:01,366
"How?

74
00:04:01,366 --> 00:04:02,199
"How does it?

75
00:04:02,199 --> 00:04:03,032
"Why?"

76
00:04:03,032 --> 00:04:05,850
Even Ms. Greer found her
hands were quite full

77
00:04:05,850 --> 00:04:10,850
when young Ada's chaos
wreaked havoc at school.

78
00:04:11,140 --> 00:04:15,820
but this much was clear
about Miss Ada Twist.

79
00:04:15,820 --> 00:04:20,763
She had all the traits
of a great scientist.

80
00:04:22,530 --> 00:04:26,870
Ada was busy that first
day of spring testing

81
00:04:26,870 --> 00:04:30,870
the sounds that make
mockingbirds birds sing,

82
00:04:30,870 --> 00:04:34,020
when a horrible stench whacked her right

83
00:04:34,020 --> 00:04:39,020
in the nose, a pungent aroma
that curled up her toes.

84
00:04:40,207 --> 00:04:44,927
"Zowie!" said Ada, which
got her to thinking,

85
00:04:44,927 --> 00:04:49,927
"What is the source of
that terrible stinking?

86
00:04:51,257 --> 00:04:55,787
"How does a nose know
there's something to smell?

87
00:04:55,787 --> 00:05:00,360
"And does it still stink if
there's no nose to tell?"

88
00:05:00,360 --> 00:05:04,743
She rattled off questions
and tapped on her chin.

89
00:05:05,680 --> 00:05:09,450
She'd start at the start
where she ought to begin.

90
00:05:09,450 --> 00:05:14,050
A mystery, a riddle, a puzzle, a quest.

91
00:05:14,050 --> 00:05:18,420
This was the moment that Ada loved best.

92
00:05:18,420 --> 00:05:20,480
Ada did research to learn

93
00:05:20,480 --> 00:05:23,900
all she could of smelling and smells,

94
00:05:23,900 --> 00:05:27,290
both the stinky and good.

95
00:05:27,290 --> 00:05:31,630
One hypothesis Ada thought could be true,

96
00:05:31,630 --> 00:05:36,333
that terrible stink came
from dad's cabbage stew.

97
00:05:37,180 --> 00:05:41,380
She tested and tested, but soon Ada knew,

98
00:05:41,380 --> 00:05:46,107
it was time to come up
with hypothesis two.

99
00:05:48,290 --> 00:05:49,800
Then Zowie!

100
00:05:49,800 --> 00:05:53,180
The stink struck again, just like that.

101
00:05:53,180 --> 00:05:57,980
Hypothesis two, "It's caused by the cat."

102
00:05:57,980 --> 00:06:01,500
The cat couldn't make
such a stink on its own.

103
00:06:01,500 --> 00:06:05,530
It needed perfume and some fancy cologne.

104
00:06:05,530 --> 00:06:07,513
So young Ada tested.

105
00:06:08,380 --> 00:06:10,003
The test was a flop.

106
00:06:10,910 --> 00:06:15,780
She started again, but her
parents yelled, "Stop."

107
00:06:15,780 --> 00:06:19,257
Look, she's trying to put the
cat in the washing machine.

108
00:06:19,257 --> 00:06:24,257
"Ada Marie, Ada Marie to
the Thinking Chair, now.

109
00:06:24,367 --> 00:06:27,067
"By the time we count three."

110
00:06:27,067 --> 00:06:29,097
"Enough," said her mother.

111
00:06:29,097 --> 00:06:31,470
"That's it," said her dad

112
00:06:31,470 --> 00:06:35,827
Her parents were frustrated,
frazzled and mad.

113
00:06:35,827 --> 00:06:37,130
"Why?"

114
00:06:37,130 --> 00:06:38,097
Ada questioned.

115
00:06:38,097 --> 00:06:39,967
"Her mother said, "No."

116
00:06:39,967 --> 00:06:42,310
"What?" Ada queried.

117
00:06:42,310 --> 00:06:44,427
Her father said, "Go.

118
00:06:44,427 --> 00:06:46,457
"You've ruined our supper.

119
00:06:46,457 --> 00:06:49,027
"You've made the cat stink.

120
00:06:49,027 --> 00:06:50,797
"Enough with your questions.

121
00:06:50,797 --> 00:06:53,600
"Now, sit there and think."

122
00:06:53,600 --> 00:06:55,400
She looked at her parents.

123
00:06:55,400 --> 00:06:57,563
Her heart turned to goo.

124
00:06:58,450 --> 00:07:02,350
Poor Ada Twist didn't know what to do.

125
00:07:02,350 --> 00:07:06,470
She sat all alone by herself in the hall

126
00:07:06,470 --> 00:07:11,470
and Ada, once more could
say nothing at all.

127
00:07:12,070 --> 00:07:16,310
And so, Ada sat, and she sat,

128
00:07:16,310 --> 00:07:21,310
and she sat and she thought
about science, and stew

129
00:07:21,450 --> 00:07:26,450
and the cat and how her
experiments made such a big mess.

130
00:07:28,687 --> 00:07:30,597
"Does it have to be so?

131
00:07:30,597 --> 00:07:33,057
"Is that part of success?

132
00:07:33,057 --> 00:07:35,810
"Are messes a problem?"

133
00:07:35,810 --> 00:07:40,317
And while she was thinking,
"What was the source

134
00:07:40,317 --> 00:07:42,357
"of that terrible stinking?"

135
00:07:43,420 --> 00:07:47,550
Ada Marie did what scientists do.

136
00:07:47,550 --> 00:07:50,190
She asked a small question,

137
00:07:50,190 --> 00:07:53,350
and then she asked two.

138
00:07:53,350 --> 00:07:58,350
And each of those led her
to three questions more

139
00:07:58,810 --> 00:08:03,810
and some of those
questions resulted in four.

140
00:08:03,850 --> 00:08:08,620
As Ada got to thinking, she really dug in.

141
00:08:08,620 --> 00:08:13,620
She scribbled her questions
and tapped on her chin.

142
00:08:13,640 --> 00:08:16,760
She started at why?

143
00:08:16,760 --> 00:08:18,260
And then what?

144
00:08:18,260 --> 00:08:19,270
How?

145
00:08:19,270 --> 00:08:20,710
And when?

146
00:08:20,710 --> 00:08:25,710
At the end of the hall,
she reached why once again.

147
00:08:27,750 --> 00:08:32,410
Her parents calmed down
and they came back to talk.

148
00:08:32,410 --> 00:08:37,410
They looked at the hallway
and just had to gawk.

149
00:08:37,850 --> 00:08:42,270
No patch of bare paint
could be seen on the wall.

150
00:08:42,270 --> 00:08:47,270
The Thinking Chair now was
the Great Thinking Hall.

151
00:08:47,790 --> 00:08:52,440
They watched their young
daughter and sighed as they did.

152
00:08:52,440 --> 00:08:55,800
What would they do with this curious kid

153
00:08:55,800 --> 00:08:59,940
who wanted to know what
the world was about?

154
00:08:59,940 --> 00:09:04,450
They smiled and whispered,
"We'll figure it out."

155
00:09:04,450 --> 00:09:06,430
And that's what they did,

156
00:09:06,430 --> 00:09:10,830
because that's what you do
when your kid has a passion

157
00:09:10,830 --> 00:09:13,580
and heart that is true.

158
00:09:13,580 --> 00:09:18,500
They remade their world and
now they're all in the act

159
00:09:18,500 --> 00:09:23,500
of helping young Ada
sort fiction from fact.

160
00:09:23,680 --> 00:09:26,520
She asks lots of questions.

161
00:09:26,520 --> 00:09:28,630
How could she resist?

162
00:09:28,630 --> 00:09:33,630
It's all in the heart
of a young scientist.

163
00:09:33,830 --> 00:09:38,350
And as for that smell,
what can Ada Twist do?

164
00:09:38,350 --> 00:09:43,350
But learn all she can with
her friends in grade two.

165
00:09:43,797 --> 00:09:48,797
Will they discover the
stink that curls toes?

166
00:09:48,980 --> 00:09:50,700
Well, that is the question.

167
00:09:50,700 --> 00:09:54,039
And someday, who knows?

168
00:09:54,039 --> 00:09:56,260
(bright upbeat music)

169
00:09:56,260 --> 00:09:59,250
Our bubble cell activity

170
00:09:59,250 --> 00:10:00,950
that's kind of an interesting term.

171
00:10:00,950 --> 00:10:02,380
Let's check it out.

172
00:10:02,380 --> 00:10:05,180
First, we're gonna need
our different materials.

173
00:10:05,180 --> 00:10:10,180
I have here some blue tempera paint mixed

174
00:10:11,120 --> 00:10:13,130
in with some soap, just the kind

175
00:10:13,130 --> 00:10:15,450
of soap that you use, the liquid soap

176
00:10:15,450 --> 00:10:17,460
that you use say, if
you're doing the dishes

177
00:10:17,460 --> 00:10:19,960
and of course, you help out
doing the dishes all the time.

178
00:10:19,960 --> 00:10:23,290
And here I have some a
red temperate paint mixed

179
00:10:23,290 --> 00:10:25,500
in with some soap and a little bit

180
00:10:25,500 --> 00:10:27,650
of water to thin it out.

181
00:10:27,650 --> 00:10:29,970
In order to make these the recipe,

182
00:10:29,970 --> 00:10:32,490
and you can kind of futz
with it a little bit,

183
00:10:32,490 --> 00:10:37,490
I use two or three of
these two ounce little jars

184
00:10:38,400 --> 00:10:40,100
of tempera paint.

185
00:10:40,100 --> 00:10:42,430
So I had a couple of different colors

186
00:10:42,430 --> 00:10:44,930
of blue in the blue one, and a couple

187
00:10:44,930 --> 00:10:47,350
of different colors of the
red to make the red one.

188
00:10:47,350 --> 00:10:49,390
You could mix them up and make some sort

189
00:10:49,390 --> 00:10:52,240
of purple-ish eggplanty color.

190
00:10:52,240 --> 00:10:54,943
You can use whatever color you want,

191
00:10:54,943 --> 00:10:56,719
but you want it to be a dark color.

192
00:10:56,719 --> 00:10:58,820
And then you're also gonna need a pie tin.

193
00:10:58,820 --> 00:11:01,070
If you're gonna be using a pie tin

194
00:11:01,070 --> 00:11:04,360
that you will then wanna bake
pie in, you could line it

195
00:11:04,360 --> 00:11:07,030
with aluminum foil, nice and tightly.

196
00:11:07,030 --> 00:11:10,050
But this paint is non-toxic

197
00:11:10,050 --> 00:11:13,160
and it's watercolor, and
it washes up real easily,

198
00:11:13,160 --> 00:11:15,810
so you could just go
ahead and use a pie tin.

199
00:11:15,810 --> 00:11:19,713
And then you need a straw,
a paper straw, of course.

200
00:11:21,520 --> 00:11:22,353
And you need some paper.

201
00:11:22,353 --> 00:11:24,050
I have some construction paper in white

202
00:11:24,050 --> 00:11:29,050
and I have some regular
paper here also in white.

203
00:11:29,180 --> 00:11:32,920
And the first thing I'm
going to do, and by the way,

204
00:11:32,920 --> 00:11:36,130
this is a little bit messy,
you probably wanna do this

205
00:11:36,130 --> 00:11:39,980
in your kitchen or the
bathroom close to a sink.

206
00:11:39,980 --> 00:11:43,640
You might spill a little and as with many

207
00:11:43,640 --> 00:11:45,890
of your activities, it's really good

208
00:11:45,890 --> 00:11:48,420
to have a grownup assistant.

209
00:11:48,420 --> 00:11:51,190
Grownups make the best assistants.

210
00:11:51,190 --> 00:11:52,210
So, let's see.

211
00:11:52,210 --> 00:11:54,660
I'm gonna try it with the blue

212
00:11:54,660 --> 00:11:59,660
and I'm going to pour some of this, Ooh,

213
00:12:00,380 --> 00:12:03,420
I have a nice bubble right at the top,

214
00:12:03,420 --> 00:12:08,190
which I'm gonna burst and
I'm going to pour some

215
00:12:08,190 --> 00:12:12,290
into, you can kinda see
the thickness of it there.

216
00:12:12,290 --> 00:12:16,200
All right, so I poured
some in and it might drip

217
00:12:16,200 --> 00:12:17,990
on the side a little bit.

218
00:12:17,990 --> 00:12:18,823
Yeah, it's okay.

219
00:12:18,823 --> 00:12:22,410
It's watercolor, it's,
non-toxic, it'll clean up.

220
00:12:22,410 --> 00:12:25,840
And this is another reason

221
00:12:25,840 --> 00:12:29,039
that you might wanna
have a grownup assistant.

222
00:12:29,039 --> 00:12:31,660
First of all, you wanna make sure

223
00:12:31,660 --> 00:12:35,700
that you don't drink up the soap solution,

224
00:12:35,700 --> 00:12:37,763
the soap and paint solution, because.

225
00:12:39,165 --> 00:12:42,565
You wanna make sure that
you are always blowing

226
00:12:42,565 --> 00:12:44,030
(instructor blows)

227
00:12:44,030 --> 00:12:48,440
blowing through the stall
straw, not slurping anything up.

228
00:12:48,440 --> 00:12:51,440
You also, to avoid splatter,

229
00:12:51,440 --> 00:12:54,530
before you start blowing into the straw,

230
00:12:54,530 --> 00:12:56,870
you wanna make sure it is well

231
00:12:56,870 --> 00:12:59,880
to the bottom of your pie pan.

232
00:12:59,880 --> 00:13:03,080
And in order to get this
a little bit deeper,

233
00:13:03,080 --> 00:13:08,080
I am going to tilt the
pie pan just a little bit.

234
00:13:08,380 --> 00:13:09,390
All right?

235
00:13:09,390 --> 00:13:11,750
So I'm gonna tilt it like
that, I'm gonna make sure

236
00:13:11,750 --> 00:13:12,880
the straw is all the way

237
00:13:12,880 --> 00:13:14,710
in, because I don't want any splatter

238
00:13:14,710 --> 00:13:17,485
and I'm gonna try blowing some bubbles.

239
00:13:17,485 --> 00:13:20,402
(bubbles rumbling)

240
00:13:28,811 --> 00:13:30,540
(indistinct) I'm gonna
try and do this quickly.

241
00:13:30,540 --> 00:13:32,690
And let's start with
the construction paper

242
00:13:33,640 --> 00:13:35,253
and set this down.

243
00:13:37,780 --> 00:13:40,858
It doesn't always work the first time.

244
00:13:40,858 --> 00:13:43,840
Oh, but it did the first time for me.

245
00:13:43,840 --> 00:13:44,673
All right.

246
00:13:44,673 --> 00:13:45,992
Oh, wow.

247
00:13:45,992 --> 00:13:48,730
Actually, that's a pretty
good one right there.

248
00:13:48,730 --> 00:13:53,730
So these are a print of
that mound of bubbles.

249
00:13:54,410 --> 00:13:56,860
I'm gonna set it down here to dry.

250
00:13:56,860 --> 00:13:59,810
I did some extra ones at home too,

251
00:13:59,810 --> 00:14:02,260
although that one's darker,
so that one looks better,

252
00:14:02,260 --> 00:14:03,403
the one I just did.

253
00:14:04,250 --> 00:14:08,690
I did a blue one, and I did a red one

254
00:14:08,690 --> 00:14:10,800
and I did some other red ones.

255
00:14:10,800 --> 00:14:12,740
I guess, that extra day or two

256
00:14:12,740 --> 00:14:16,230
of letting the soap and the
paint really mixed together.

257
00:14:16,230 --> 00:14:19,130
And by the way, let me go back
to the recipe for a second,

258
00:14:19,130 --> 00:14:23,870
besides maybe four to six
ounces of tempora paint,

259
00:14:23,870 --> 00:14:27,490
I maybe had 1/3 of a cup, 1/4 cup

260
00:14:27,490 --> 00:14:30,450
or two 1/3 of a cup of
the dishwashing soap.

261
00:14:30,450 --> 00:14:33,930
And then I added some water
to get this thickness.

262
00:14:33,930 --> 00:14:35,710
You kinda saw the thickness.

263
00:14:35,710 --> 00:14:40,280
It's not like water thin,

264
00:14:40,280 --> 00:14:43,220
it's just a little like
soupy, kind of like

265
00:14:43,220 --> 00:14:46,920
I dunno, butternut squash
soup, maybe, that thickness.

266
00:14:46,920 --> 00:14:49,410
And that extra couple
of days of just sitting

267
00:14:49,410 --> 00:14:52,800
there in the jar really
let it blend together.

268
00:14:52,800 --> 00:14:57,790
So the reason that I call
this a bubble cell activity

269
00:14:57,790 --> 00:15:00,450
is these bubble shapes,

270
00:15:00,450 --> 00:15:03,020
which are not all perfectly round,

271
00:15:03,020 --> 00:15:05,620
and they're not all the same size,

272
00:15:05,620 --> 00:15:08,330
and they all kind of
meet up with each other.

273
00:15:08,330 --> 00:15:12,610
They share their little outside skins,

274
00:15:12,610 --> 00:15:14,880
their little outside areas.

275
00:15:14,880 --> 00:15:19,560
They look very, very much like real cells

276
00:15:19,560 --> 00:15:21,400
that you see in nature.

277
00:15:21,400 --> 00:15:24,350
Let me show you a picture of skin cells.

278
00:15:24,350 --> 00:15:26,800
These are skin cells that were dyed,

279
00:15:26,800 --> 00:15:29,000
so you can see them better.

280
00:15:29,000 --> 00:15:32,970
And you can see they're not
all exactly the same shape,

281
00:15:32,970 --> 00:15:35,430
they're not all exactly the same size,

282
00:15:35,430 --> 00:15:38,730
but they all share this outside skin,

283
00:15:38,730 --> 00:15:41,830
which is called the cell membrane.

284
00:15:41,830 --> 00:15:44,860
Looks very, very close
to what we just made.

285
00:15:44,860 --> 00:15:49,860
Also, these human skin
cells have little dots

286
00:15:50,150 --> 00:15:51,574
that you see.

287
00:15:51,574 --> 00:15:53,070
that's the nucleus in each cell.

288
00:15:53,070 --> 00:15:55,230
Your bubble cells don't have a nucleus,

289
00:15:55,230 --> 00:15:57,810
that's sort of the center of the cell,

290
00:15:57,810 --> 00:16:01,860
like the heart, and the soul
and the brain of the cell.

291
00:16:01,860 --> 00:16:03,050
You could draw them

292
00:16:03,050 --> 00:16:06,760
in to the bubble cell
prints that you made.

293
00:16:06,760 --> 00:16:11,630
And you can notice how
they're not all the same size

294
00:16:11,630 --> 00:16:14,480
and not all the same
shape, but they all share

295
00:16:14,480 --> 00:16:17,500
those cell membranes are kind
of like packed in together,

296
00:16:17,500 --> 00:16:20,270
just like your bubble cell print.

297
00:16:20,270 --> 00:16:24,400
The other thing is let's look
at a picture of plant cells.

298
00:16:24,400 --> 00:16:29,400
Again, these were from a picture
taken under a microscope.

299
00:16:29,520 --> 00:16:34,310
And you can see how the
shapes are not all the same.

300
00:16:34,310 --> 00:16:38,400
They look really, really similar
to your bubble cell shapes,

301
00:16:38,400 --> 00:16:43,400
but they all share that outside
membrane or that cell wall.

302
00:16:44,810 --> 00:16:49,248
So it's kind of interesting
to be able to do a model

303
00:16:49,248 --> 00:16:53,010
with bubble, bubble solution, and paint

304
00:16:53,010 --> 00:16:57,020
and a little bit of water
that models something

305
00:16:57,020 --> 00:16:59,200
that you find in nature.

306
00:16:59,200 --> 00:17:02,190
And maybe it'll lead you to
doing some more research.

307
00:17:02,190 --> 00:17:04,210
Maybe you have books at home,

308
00:17:04,210 --> 00:17:07,600
maybe you have somebody
who's taken a biology class

309
00:17:07,600 --> 00:17:08,870
and you can talk to them

310
00:17:08,870 --> 00:17:12,080
or maybe you can even look
up stuff on the internet.

311
00:17:12,080 --> 00:17:14,480
But I like this activity,

312
00:17:14,480 --> 00:17:18,440
because it's pretty, but it also leads

313
00:17:18,440 --> 00:17:22,169
you to think more about
something that occurs naturally.

314
00:17:22,169 --> 00:17:24,350
(bright upbeat music)

315
00:17:24,350 --> 00:17:26,590
It's time for poetry corner.

316
00:17:26,590 --> 00:17:30,280
I couldn't find a really
good poem about cells,

317
00:17:30,280 --> 00:17:31,960
so I wrote one myself.

318
00:17:31,960 --> 00:17:33,210
Let's see what you think.

319
00:17:34,240 --> 00:17:37,700
I have trillions of cells inside of me

320
00:17:37,700 --> 00:17:40,740
and on the outside too.

321
00:17:40,740 --> 00:17:45,050
My skin, my tongue, my heart, my lungs,

322
00:17:45,050 --> 00:17:48,313
my eyes and blood, it's true.

323
00:17:48,313 --> 00:17:51,700
All animals and plants have cells.

324
00:17:51,700 --> 00:17:55,140
And all those cells have parts.

325
00:17:55,140 --> 00:18:00,053
A membrane, mitochondria,
a nucleus to start.

326
00:18:01,260 --> 00:18:04,841
Our cells, they know just what to do,

327
00:18:04,841 --> 00:18:07,573
'cause that is nature's plan.

328
00:18:08,590 --> 00:18:13,590
These tiny living cells all
serve to make me who I am.

329
00:18:14,649 --> 00:18:17,899
(bright upbeat music)
