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

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

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

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)
Join us for Storytime Science—a storybook read-aloud followed by a simple related activity geared toward very young children. This month, join in as the Exploratorium's own Vivian Altmann reads Ada Twist, Scientist, by Andrea Beaty and illustrated by David Roberts. Then: What are bubble cells? They're what happens when you mix paint and bubble solution and make a print of the result! For this activity, you'll need: 4 oz. or more of liquid tempera paint (watercolor and nontoxic); dark colors work best 1/4 c. dishwashing liquid a pie tin a straw a sheet of paper (white construction paper is best, but regular white paper will do) This activity can get a little messy, so have a grown-up assistant at hand and wear play clothes—nothing fancy.
