1
00:00:00,562 --> 00:00:03,480
(gently chiming bells)

2
00:00:03,480 --> 00:00:04,720
- Hello friends,

3
00:00:04,720 --> 00:00:06,670
welcome to Circle Time.

4
00:00:06,670 --> 00:00:10,130
I am Caroline, from the
Khan Academy Kids team,

5
00:00:10,130 --> 00:00:13,160
and I'm here today with my friend Sophie.

6
00:00:13,160 --> 00:00:13,993
Hi Sophie.

7
00:00:13,993 --> 00:00:15,850
- Hi Caroline.

8
00:00:15,850 --> 00:00:17,560
Hi friends.

9
00:00:17,560 --> 00:00:19,800
I am so excited to be

10
00:00:19,800 --> 00:00:24,439
with you today for circle
time with Khan Academy Kids.

11
00:00:24,439 --> 00:00:26,663
- How are you all feeling today?

12
00:00:28,320 --> 00:00:30,220
- Good question, Caroline.

13
00:00:30,220 --> 00:00:31,617
It's nice to ask our friends,

14
00:00:31,617 --> 00:00:34,280
how they're feeling today.

15
00:00:34,280 --> 00:00:39,280
And I'm looking around
the circle at our friends,

16
00:00:39,900 --> 00:00:43,980
and some of our friends
are feeling excited,

17
00:00:43,980 --> 00:00:47,010
and some of our friends,

18
00:00:47,010 --> 00:00:50,790
our friends are feeling, happy

19
00:00:50,790 --> 00:00:51,981
and one of our friends

20
00:00:51,981 --> 00:00:54,950
is feeling a little bit frustrated,

21
00:00:54,950 --> 00:00:57,933
because they would really
like to go outside.

22
00:00:59,640 --> 00:01:03,650
And another one of our friends
is feeling very active,

23
00:01:03,650 --> 00:01:05,883
like they have a lot of energy.

24
00:01:07,290 --> 00:01:11,390
- Well, I am so excited to see all of you.

25
00:01:11,390 --> 00:01:13,580
Thank you for joining us.

26
00:01:13,580 --> 00:01:18,580
We have a lot of splashy water fun today.

27
00:01:18,833 --> 00:01:22,220
We have a story about some water

28
00:01:22,220 --> 00:01:27,220
and it's called "That Won't
Float!" by Cynthia Platt.

29
00:01:31,110 --> 00:01:32,570
One rainy day,

30
00:01:32,570 --> 00:01:34,827
Kodi went to visit Sandy.

31
00:01:34,827 --> 00:01:36,207
"We can't play outside,"

32
00:01:36,207 --> 00:01:37,671
Sandy told Kodi.

33
00:01:37,671 --> 00:01:40,067
"what should we do?"

34
00:01:40,067 --> 00:01:44,824
"Let's play Sink or Float!" Kodi said.

35
00:01:44,824 --> 00:01:48,333
Friends, have any of you
ever played Sink or Float?

36
00:01:51,694 --> 00:01:55,439
- Some of our friends
are nodding Caroline.

37
00:01:55,439 --> 00:01:58,563
- Well, let's find out
what the game is about.

38
00:02:00,350 --> 00:02:04,447
They found a large container
and filled it with water.

39
00:02:04,447 --> 00:02:07,607
"We need to be careful!"Sandy exclaimed.

40
00:02:07,607 --> 00:02:10,167
"We don't want to spill any."

41
00:02:10,167 --> 00:02:12,893
"We're always careful." Kodi replied.

42
00:02:14,169 --> 00:02:17,217
"I'll try this ball first," said Kodi.

43
00:02:17,217 --> 00:02:18,167
"it's light,

44
00:02:18,167 --> 00:02:20,537
"so I bet it'll float."

45
00:02:20,537 --> 00:02:22,827
"I have chosen this rock." Sandy replied.

46
00:02:22,827 --> 00:02:23,660
"It's heavy,

47
00:02:23,660 --> 00:02:26,490
"so it will probably sink."

48
00:02:26,490 --> 00:02:30,585
The ball babbed to the top,
and the rock sank down.

49
00:02:30,585 --> 00:02:33,543
"Our predictions were right!" Kodi said.

50
00:02:37,667 --> 00:02:41,727
"I guess this wooden block
will sink too," Sandy said,

51
00:02:41,727 --> 00:02:43,093
"it feels heavy."

52
00:02:43,093 --> 00:02:46,000
When she put the block in though,

53
00:02:46,000 --> 00:02:47,670
It didn't sink.

54
00:02:47,670 --> 00:02:49,750
Instead, it bobbed on the surface,

55
00:02:49,750 --> 00:02:51,087
like the ball did.

56
00:02:51,087 --> 00:02:53,610
"My prediction wasn't right that time."

57
00:02:53,610 --> 00:02:54,793
she told Kodi.

58
00:02:56,280 --> 00:02:59,023
Friends, do you know what a prediction is?

59
00:03:00,160 --> 00:03:04,110
- Is it when you have an idea
how something might turn out,

60
00:03:04,110 --> 00:03:07,733
a guess, about what might
happen is a prediction.

61
00:03:09,693 --> 00:03:11,633
- So I think in this case,

62
00:03:12,902 --> 00:03:17,460
Sandy was predicting that
the block would sink.

63
00:03:19,497 --> 00:03:22,867
"My turn, I'll try this
dinosaur." Kodi said.

64
00:03:22,867 --> 00:03:25,277
"That won't float, Sandy replied.

65
00:03:25,277 --> 00:03:27,227
"it's too big."

66
00:03:27,227 --> 00:03:29,467
"It won't float." Kodi agreed.

67
00:03:29,467 --> 00:03:32,560
"because it's going to...

68
00:03:34,450 --> 00:03:37,010
"Cannanball." Kodi exclaimed.

69
00:03:37,010 --> 00:03:39,900
Water splashed everywhere.

70
00:03:39,900 --> 00:03:43,877
Kodi and Sandy were as
wet as the dinosaur!

71
00:03:43,877 --> 00:03:47,547
"Oh my," Sandy said, "Why'd you do that?"

72
00:03:47,547 --> 00:03:51,033
"Because it's fun to
get wet."Kodi replied.

73
00:03:54,517 --> 00:03:56,067
"You're right." Sandy agreed.

74
00:03:56,067 --> 00:03:58,457
"Look, the sun has come out.

75
00:03:58,457 --> 00:04:01,167
"How do you feel about going for a swim?"

76
00:04:01,167 --> 00:04:03,180
"Let's do it." Kodi said.

77
00:04:03,180 --> 00:04:06,453
It turned out. They both
liked the cannanball, too.

78
00:04:08,490 --> 00:04:10,270
What a fun splashy story,

79
00:04:10,270 --> 00:04:12,436
It was actually a splashing story.

80
00:04:12,436 --> 00:04:14,320
(laughing)

81
00:04:14,320 --> 00:04:15,400
So friends,

82
00:04:15,400 --> 00:04:19,283
should we try to play Sink
or Float on Circle Time?

83
00:04:22,500 --> 00:04:23,510
- Yeah, let's see,

84
00:04:23,510 --> 00:04:25,560
if we can predict

85
00:04:25,560 --> 00:04:27,200
what might sink,

86
00:04:27,200 --> 00:04:29,420
and what might float.

87
00:04:29,420 --> 00:04:30,870
- Sounds good.

88
00:04:30,870 --> 00:04:32,210
Hold on for one second,

89
00:04:32,210 --> 00:04:34,383
I have to go get my bowl of water.

90
00:04:35,460 --> 00:04:36,963
- Oh, okay.

91
00:04:39,740 --> 00:04:43,240
- All right friends. Are you ready?

92
00:04:43,240 --> 00:04:46,913
Let's try, a rock.

93
00:04:48,252 --> 00:04:49,863
You see this rock? It's pretty.

94
00:04:51,936 --> 00:04:53,560
Mm-hmm.

95
00:04:53,560 --> 00:04:56,700
It's pretty, heavy and dense.

96
00:04:56,700 --> 00:04:59,263
What do you think will happen?

97
00:05:02,850 --> 00:05:06,080
- Oh, I just asked some of our friends,

98
00:05:06,080 --> 00:05:11,080
and one of our friends says
they have seen a rock sink,

99
00:05:11,130 --> 00:05:16,130
into some water before.
So, I think it might sink.

100
00:05:17,300 --> 00:05:18,773
- Okay. Let's try it.

101
00:05:20,130 --> 00:05:21,270
Whoa.

102
00:05:21,270 --> 00:05:22,440
(chuckles)

103
00:05:22,440 --> 00:05:23,960
It sank to the bottom.

104
00:05:23,960 --> 00:05:26,663
Can you see it's all the
way... It's underneath.

105
00:05:27,680 --> 00:05:30,730
- Oh yeah. It went down,

106
00:05:30,730 --> 00:05:33,960
below the surface of the water,

107
00:05:33,960 --> 00:05:37,150
and sank to the bottom
of the bowl, friends.

108
00:05:37,150 --> 00:05:40,110
Because it's quite heavy.

109
00:05:40,110 --> 00:05:40,943
- That's right.

110
00:05:42,287 --> 00:05:45,773
And what about this boat?

111
00:05:47,198 --> 00:05:49,600
Actually a paper boat.

112
00:05:49,600 --> 00:05:51,964
We made it out of paper.

113
00:05:51,964 --> 00:05:53,750
What do you think? It's a boat,

114
00:05:53,750 --> 00:05:55,313
So there's maybe one clue.

115
00:05:56,300 --> 00:05:59,529
- Well, one of our friends is saying

116
00:05:59,529 --> 00:06:02,480
that boats usually float.

117
00:06:02,480 --> 00:06:05,780
So if it's a good boat, it should Float.

118
00:06:05,780 --> 00:06:07,955
- Okay. Should we try it?

119
00:06:07,955 --> 00:06:09,205
- Mm-hmm
- Mm-hmm

120
00:06:10,844 --> 00:06:12,213
- Oh, Cool.

121
00:06:12,213 --> 00:06:13,396
- That is cool.

122
00:06:13,396 --> 00:06:16,029
And just for fun, I brought a straw.

123
00:06:16,029 --> 00:06:17,860
I don't know what will happen,

124
00:06:17,860 --> 00:06:21,033
if I blow some air at the
boat, should we try it?

125
00:06:22,554 --> 00:06:24,923
- Mm- hmm. Oh wow.

126
00:06:26,592 --> 00:06:28,730
- It's kind of like wind.

127
00:06:28,730 --> 00:06:30,170
- That's cool.

128
00:06:30,170 --> 00:06:34,750
- Yeah. So why do you
think, some things sink

129
00:06:34,750 --> 00:06:36,883
and some things float?

130
00:06:39,798 --> 00:06:42,960
- Whoa, I don't know Caroline.

131
00:06:42,960 --> 00:06:45,820
Can you help us out, please?

132
00:06:45,820 --> 00:06:50,630
- So I think things are made
out of tiny, tiny molecules.

133
00:06:50,630 --> 00:06:55,290
So you can't see them
unless you use a microscope,

134
00:06:55,290 --> 00:06:57,616
That's kinda like this.

135
00:06:57,616 --> 00:06:59,420
So everything that we see, is made out

136
00:06:59,420 --> 00:07:01,490
of a little tiny minute molecules.

137
00:07:01,490 --> 00:07:04,010
So if the molecules
are very close together

138
00:07:04,010 --> 00:07:09,010
and are very dense, like
in this rock, it will sink,

139
00:07:09,350 --> 00:07:12,973
because it's denser than
the molecules in the water.

140
00:07:15,930 --> 00:07:20,207
But a boat like this floats,

141
00:07:22,760 --> 00:07:26,923
because the molecules are further apart.

142
00:07:26,923 --> 00:07:30,120
And I also think in this
case, because it's spread out

143
00:07:30,120 --> 00:07:34,913
over some surface area, that
helps it float on the surface.

144
00:07:37,090 --> 00:07:41,710
Let's try a few more.Look at
this egg. It's not a real egg,

145
00:07:41,710 --> 00:07:43,513
It's a little shaker egg.

146
00:07:46,680 --> 00:07:48,320
- Maybe it will float.

147
00:07:48,320 --> 00:07:49,800
- Let's try.

148
00:07:49,800 --> 00:07:51,593
Ooh, it does float.

149
00:07:52,940 --> 00:07:54,020
- Wow.

150
00:07:54,020 --> 00:07:57,760
- And then, this other
egg, it's hollow inside.

151
00:07:57,760 --> 00:07:59,443
So there's air inside.

152
00:08:01,290 --> 00:08:05,960
- Oh, interesting. It floats right on top.

153
00:08:05,960 --> 00:08:08,290
The other egg has some shakers in it,

154
00:08:08,290 --> 00:08:12,600
so it's a little heavier.
So it sinks halfway down,

155
00:08:12,600 --> 00:08:15,710
and just has a little bit peeking out.

156
00:08:15,710 --> 00:08:19,670
And the egg that's full of
air, which is very light,

157
00:08:19,670 --> 00:08:23,140
those molecules are extra spaced out,

158
00:08:23,140 --> 00:08:26,160
it's just bobbing along right on top.

159
00:08:26,160 --> 00:08:28,690
- Exactly, just like Sophie was saying,

160
00:08:28,690 --> 00:08:29,692
that air is very light.

161
00:08:29,692 --> 00:08:32,370
That molecules are spread apart

162
00:08:32,370 --> 00:08:34,190
and this is a hollow egg,

163
00:08:34,190 --> 00:08:36,460
so there's nothing inside
of it except for air.

164
00:08:36,460 --> 00:08:37,710
So that's why it looks...

165
00:08:39,820 --> 00:08:42,616
One more, I have this funny brush.

166
00:08:42,616 --> 00:08:43,793
What do you think?

167
00:08:45,070 --> 00:08:47,593
What's the prediction on this one?

168
00:08:51,060 --> 00:08:54,740
- I need to ask our friends.

169
00:08:54,740 --> 00:08:56,930
Well, one of our friends predicts,

170
00:08:56,930 --> 00:09:00,820
that this brush will sink to the bottom.

171
00:09:00,820 --> 00:09:03,403
That it's too heavy to float.

172
00:09:04,690 --> 00:09:05,823
- Let's try it.

173
00:09:10,460 --> 00:09:13,900
- Oh wow. Well, it's
good that we had a guess,

174
00:09:13,900 --> 00:09:15,450
and that we had a go

175
00:09:15,450 --> 00:09:20,210
and it seems like
actually, the brush floats!

176
00:09:20,210 --> 00:09:21,043
- It does.

177
00:09:23,710 --> 00:09:24,800
That was the last one.

178
00:09:24,800 --> 00:09:28,520
But I have a very interesting one.

179
00:09:28,520 --> 00:09:31,193
What do you think will
happen with bubbles?

180
00:09:32,540 --> 00:09:34,440
Should we try the bubbles?

181
00:09:34,440 --> 00:09:35,950
If I blow bubbles

182
00:09:35,950 --> 00:09:38,850
and they land on the water,
what do you think will happen?

183
00:09:41,640 --> 00:09:44,010
- Well, it's full of air,

184
00:09:44,010 --> 00:09:48,863
so they should float on top of
the water, but I don't know.

185
00:09:51,620 --> 00:09:54,373
- Can't even get it onto
the water. Let's try again.

186
00:09:58,900 --> 00:10:02,633
- A few little bubbles
are floating on the water.

187
00:10:05,190 --> 00:10:06,023
- There. We got a big one.

188
00:10:07,039 --> 00:10:08,739
- A big one, it looks like a dome.

189
00:10:10,574 --> 00:10:15,260
- Yes, that one has lots of air in it.

190
00:10:15,260 --> 00:10:16,710
That's floating on the water.

191
00:10:17,630 --> 00:10:20,970
Thank you friends for
playing Sink or Float.

192
00:10:20,970 --> 00:10:23,163
Just like Kodi and Sandy.

193
00:10:24,080 --> 00:10:25,973
Should we do some Show and Tell now?

194
00:10:27,820 --> 00:10:31,050
- Ooh. Yeah. I would love
to do some Show and Tell.

195
00:10:31,050 --> 00:10:34,330
And if our friends... while
you're doing this Show and Tell,

196
00:10:34,330 --> 00:10:39,160
if our friends, ever want to
see any of our other books,

197
00:10:39,160 --> 00:10:41,480
and see what else Kodi and

198
00:10:41,480 --> 00:10:43,940
Sandy and their friends are getting up to,

199
00:10:43,940 --> 00:10:48,920
they can probably download
our app, Khan Academy Kids.

200
00:10:48,920 --> 00:10:52,430
- That's right. We have
lots of books in the app.

201
00:10:52,430 --> 00:10:55,150
All right. Let's do some Show and Tell.

202
00:10:55,150 --> 00:10:56,013
All right.

203
00:10:57,425 --> 00:11:01,380
Ari sent us a drawing
of all those bath toys.

204
00:11:01,380 --> 00:11:04,010
I think those-- what do you think friends,

205
00:11:04,010 --> 00:11:06,400
will those sink or float?

206
00:11:06,400 --> 00:11:07,233
- Mm- hmm,

207
00:11:09,770 --> 00:11:12,163
I think they might float.

208
00:11:14,600 --> 00:11:15,840
- I think so too.

209
00:11:15,840 --> 00:11:17,410
One looks like a submarine,

210
00:11:17,410 --> 00:11:20,163
and one looks like a dinosaur.

211
00:11:21,150 --> 00:11:25,693
- Yeah. They're very cool
Dinosaur with pink and orange

212
00:11:27,690 --> 00:11:29,520
- And a nice smile.

213
00:11:29,520 --> 00:11:30,920
- Thank you Ari.

214
00:11:30,920 --> 00:11:35,920
- And Veda sent me their
drawing of a Dino and Submarine.

215
00:11:38,650 --> 00:11:41,740
- Wow. I think there's a
theme here, isn't there?

216
00:11:41,740 --> 00:11:43,820
That's two dinosaurs we've seen,

217
00:11:43,820 --> 00:11:47,360
and two submarines. Thank you, Veda.

218
00:11:47,360 --> 00:11:48,700
- Thank you.

219
00:11:48,700 --> 00:11:50,980
And now we have Quillin, who's going

220
00:11:50,980 --> 00:11:54,379
to show us how to surf in the ocean.

221
00:11:54,379 --> 00:11:56,810
He has practiced a lot,

222
00:11:56,810 --> 00:12:01,530
and his surfboard floats,
on the top of the ocean.

223
00:12:01,530 --> 00:12:02,860
Hello Quillin.

224
00:12:02,860 --> 00:12:04,220
Hi Quillin.

225
00:12:04,220 --> 00:12:07,220
Hi, I'm Quillin. I'm going
to teach you how to surf.

226
00:12:07,220 --> 00:12:09,350
First, you paddle out,

227
00:12:09,350 --> 00:12:11,863
and then when you see
waves you start paddling,

228
00:12:14,206 --> 00:12:15,200
then stand up,

229
00:12:15,200 --> 00:12:17,335
and then you can try a few tricks,

230
00:12:17,335 --> 00:12:21,135
but if you're a beginner and
you have never surfed before,

231
00:12:21,135 --> 00:12:23,646
then it's probably best for you

232
00:12:23,646 --> 00:12:26,313
to catch water instead of waves.

233
00:12:27,511 --> 00:12:29,413
- (woman)Okay. Are you
ready to go surf? Let's go!

234
00:12:34,266 --> 00:12:37,433
(bright upbeat music)

235
00:12:39,561 --> 00:12:41,561
(waves)

236
00:12:44,019 --> 00:12:45,960
(soft music)

237
00:12:45,960 --> 00:12:48,310
(soft music)

238
00:12:48,310 --> 00:12:50,893
(ocean sounds)

239
00:12:53,015 --> 00:12:55,265
(cheering)

240
00:13:01,896 --> 00:13:04,313
(soft music)

241
00:13:13,893 --> 00:13:16,476
(ocean sounds)

242
00:13:25,056 --> 00:13:28,380
- Thank you Quillin for
showing us how to surf.

243
00:13:28,380 --> 00:13:32,248
That was a special video
that you shared with us.

244
00:13:32,248 --> 00:13:34,250
And now to wrap it up,

245
00:13:34,250 --> 00:13:35,930
we have one more,

246
00:13:35,930 --> 00:13:37,000
Semi is going,

247
00:13:37,000 --> 00:13:40,300
to show us how to carefully wash,

248
00:13:40,300 --> 00:13:42,603
our hands, which is very important.

249
00:13:42,603 --> 00:13:45,475
Thanks so much for sending us this video.

250
00:13:45,475 --> 00:13:48,223
- (girl)This is the way we wash our hands.

251
00:13:51,687 --> 00:13:54,207
So, what do you do first?

252
00:13:54,207 --> 00:13:59,207
- You put on some soap then wash in water.

253
00:14:02,360 --> 00:14:05,323
Then do like this, some a little

254
00:14:05,323 --> 00:14:08,687
to get the soap out of there.
Because there might be some...

255
00:14:08,687 --> 00:14:11,823
- (girl) Now you have to rub
the back with some more soap.

256
00:14:12,980 --> 00:14:16,970
You need to rub the back of
your hand with more soap.

257
00:14:19,270 --> 00:14:21,919
(soft music)

258
00:14:21,919 --> 00:14:24,221
(running water)

259
00:14:24,221 --> 00:14:27,069
- ♪ wash your hand, wash your hand ♪

260
00:14:27,069 --> 00:14:32,069
- (girl) can you you
show them the butterfly?

261
00:14:35,300 --> 00:14:37,123
And now, cut the dog.

262
00:14:42,394 --> 00:14:44,811
(soft music)

263
00:14:46,336 --> 00:14:50,430
- (girl) and now you
need a towel to dry it.

264
00:14:50,430 --> 00:14:53,523
- I usually dry like this
because I can't reach up there.

265
00:14:55,460 --> 00:14:56,852
- (girl) say bye to everybody.

266
00:14:56,852 --> 00:14:59,970
- Bye guys... watch more...

267
00:15:02,950 --> 00:15:05,031
- Remember to wash your hands.

268
00:15:05,031 --> 00:15:06,060
- Always.

269
00:15:06,060 --> 00:15:10,033
- Thank you Semi for showing
us how to wash our hands.

270
00:15:11,020 --> 00:15:14,450
- Wow. That was such a cool end.

271
00:15:14,450 --> 00:15:17,450
We had floating and sinking,

272
00:15:17,450 --> 00:15:21,500
we had lots of Show and Tell stories,

273
00:15:21,500 --> 00:15:25,873
We saw Quill and surfing,
and then we were reminded,

274
00:15:27,025 --> 00:15:30,820
how important it is to wash
our hands with soap and water.

275
00:15:30,820 --> 00:15:34,267
What a great water kind of day--

276
00:15:35,200 --> 00:15:36,505
- It was.

277
00:15:36,505 --> 00:15:38,000
(laughing)

278
00:15:38,000 --> 00:15:40,210
Thank you all for joining us.

279
00:15:40,210 --> 00:15:43,520
And we will see you all next time.

280
00:15:43,520 --> 00:15:45,019
Goodbye for now, from Caroline

281
00:15:45,019 --> 00:15:48,769
Sophie and the Khan
Academy Kids team.Bye bye.

282
00:15:48,769 --> 00:15:49,602
- Bye friends.
