Kodi replied. 00:02:14.169 --> 00:02:17.217 "I'll try this ball first," said Kodi. 00:02:17.217 --> 00:02:18.167 "it's light, 00:02:18.167 --> 00:02:20.537 "so I bet it'll float." 00:02:20.537 --> 00:02:22.827 "I have chosen this rock." Sandy replied. 00:02:22.827 --> 00:02:23.660 "It's heavy, 00:02:23.660 --> 00:02:26.490 "so it will probably sink." 00:02:26.490 --> 00:02:30.585 The ball babbed to the top, and the rock sank down. 00:02:30.585 --> 00:02:33.543 "Our predictions were right!" Kodi said. 00:02:37.667 --> 00:02:41.727 "I guess this wooden block will sink too," Sandy said, 00:02:41.727 --> 00:02:43.093 "it feels heavy." 00:02:43.093 --> 00:02:46.000 When she put the block in though, 00:02:46.000 --> 00:02:47.670 It didn't sink. 00:02:47.670 --> 00:02:49.750 Instead, it bobbed on the surface, 00:02:49.750 --> 00:02:51.087 like the ball did. 00:02:51.087 --> 00:02:53.610 "My prediction wasn't right that time." 00:02:53.610 --> 00:02:54.793 she told Kodi. 00:02:56.280 --> 00:02:59.023 Friends, do you know what a prediction is? 00:03:00.160 --> 00:03:04.110 - Is it when you have an idea how something might turn out, 00:03:04.110 --> 00:03:07.733 a guess, about what might happen is a prediction. 00:03:09.693 --> 00:03:11.633 - So I think in this case, 00:03:12.902 --> 00:03:17.460 Sandy was predicting that the block would sink. 00:03:19.497 --> 00:03:22.867 "My turn, I'll try this dinosaur." Kodi said. 00:03:22.867 --> 00:03:25.277 "That won't float, Sandy replied. 00:03:25.277 --> 00:03:27.227 "it's too big." 00:03:27.227 --> 00:03:29.467 "It won't float." Kodi agreed. 00:03:29.467 --> 00:03:32.560 "because it's going to... 00:03:34.450 --> 00:03:37.010 "Cannanball." Kodi exclaimed. 00:03:37.010 --> 00:03:39.900 Water splashed everywhere. 00:03:39.900 --> 00:03:43.877 Kodi and Sandy were as wet as the dinosaur! 00:03:43.877 --> 00:03:47.547 "Oh my," Sandy said, "Why'd you do that?" 00:03:47.547 --> 00:03:51.033 "Because it's fun to get wet."Kodi replied. 00:03:54.517 --> 00:03:56.067 "You're right." Sandy agreed. 00:03:56.067 --> 00:03:58.457 "Look, the sun has come out. 00:03:58.457 --> 00:04:01.167 "How do you feel about going for a swim?" 00:04:01.167 --> 00:04:03.180 "Let's do it." Kodi said. 00:04:03.180 --> 00:04:06.453 It turned out. They both liked the cannanball, too. 00:04:08.490 --> 00:04:10.270 What a fun splashy story, 00:04:10.270 --> 00:04:12.436 It was actually a splashing story. 00:04:12.436 --> 00:04:14.320 (laughing) 00:04:14.320 --> 00:04:15.400 So friends, 00:04:15.400 --> 00:04:19.283 should we try to play Sink or Float on Circle Time? 00:04:22.500 --> 00:04:23.510 - Yeah, let's see, 00:04:23.510 --> 00:04:25.560 if we can predict 00:04:25.560 --> 00:04:27.200 what might sink, 00:04:27.200 --> 00:04:29.420 and what might float. 00:04:29.420 --> 00:04:30.870 - Sounds good. 00:04:30.870 --> 00:04:32.210 Hold on for one second, 00:04:32.210 --> 00:04:34.383 I have to go get my bowl of water. 00:04:35.460 --> 00:04:36.963 - Oh, okay. 00:04:39.740 --> 00:04:43.240 - All right friends. Are you ready? 00:04:43.240 --> 00:04:46.913 Let's try, a rock. 00:04:48.252 --> 00:04:49.863 You see this rock? It's pretty. 00:04:51.936 --> 00:04:53.560 Mm-hmm. 00:04:53.560 --> 00:04:56.700 It's pretty, heavy and dense. 00:04:56.700 --> 00:04:59.263 What do you think will happen? 00:05:02.850 --> 00:05:06.080 - Oh, I just asked some of our friends, 00:05:06.080 --> 00:05:11.080 and one of our friends says they have seen a rock sink, 00:05:11.130 --> 00:05:16.130 into some water before. So, I think it might sink. 00:05:17.300 --> 00:05:18.773 - Okay. Let's try it. 00:05:20.130 --> 00:05:21.270 Whoa. 00:05:21.270 --> 00:05:22.440 (chuckles) 00:05:22.440 --> 00:05:23.960 It sank to the bottom. 00:05:23.960 --> 00:05:26.663 Can you see it's all the way... It's underneath. 00:05:27.680 --> 00:05:30.730 - Oh yeah. It went down, 00:05:30.730 --> 00:05:33.960 below the surface of the water, 00:05:33.960 --> 00:05:37.150 and sank to the bottom of the bowl, friends. 00:05:37.150 --> 00:05:40.110 Because it's quite heavy. 00:05:40.110 --> 00:05:40.943 - That's right. 00:05:42.287 --> 00:05:45.773 And what about this boat? 00:05:47.198 --> 00:05:49.600 Actually a paper boat. 00:05:49.600 --> 00:05:51.964 We made it out of paper. 00:05:51.964 --> 00:05:53.750 What do you think? It's a boat, 00:05:53.750 --> 00:05:55.313 So there's maybe one clue. 00:05:56.300 --> 00:05:59.529 - Well, one of our friends is saying 00:05:59.529 --> 00:06:02.480 that boats usually float. 00:06:02.480 --> 00:06:05.780 So if it's a good boat, it should Float. 00:06:05.780 --> 00:06:07.955 - Okay. Should we try it? 00:06:07.955 --> 00:06:09.205 - Mm-hmm - Mm-hmm 00:06:10.844 --> 00:06:12.213 - Oh, Cool. 00:06:12.213 --> 00:06:13.396 - That is cool. 00:06:13.396 --> 00:06:16.029 And just for fun, I brought a straw. 00:06:16.029 --> 00:06:17.860 I don't know what will happen, 00:06:17.860 --> 00:06:21.033 if I blow some air at the boat, should we try it? 00:06:22.554 --> 00:06:24.923 - Mm- hmm. Oh wow. 00:06:26.592 --> 00:06:28.730 - It's kind of like wind. 00:06:28.730 --> 00:06:30.170 - That's cool. 00:06:30.170 --> 00:06:34.750 - Yeah. So why do you think, some things sink 00:06:34.750 --> 00:06:36.883 and some things float? 00:06:39.798 --> 00:06:42.960 - Whoa, I don't know Caroline. 00:06:42.960 --> 00:06:45.820 Can you help us out, please? 00:06:45.820 --> 00:06:50.630 - So I think things are made out of tiny, tiny molecules. 00:06:50.630 --> 00:06:55.290 So you can't see them unless you use a microscope, 00:06:55.290 --> 00:06:57.616 That's kinda like this. 00:06:57.616 --> 00:06:59.420 So everything that we see, is made out 00:06:59.420 --> 00:07:01.490 of a little tiny minute molecules. 00:07:01.490 --> 00:07:04.010 So if the molecules are very close together 00:07:04.010 --> 00:07:09.010 and are very dense, like in this rock, it will sink, 00:07:09.350 --> 00:07:12.973 because it's denser than the molecules in the water. 00:07:15.930 --> 00:07:20.207 But a boat like this floats, 00:07:22.760 --> 00:07:26.923 because the molecules are further apart. 00:07:26.923 --> 00:07:30.120 And I also think in this case, because it's spread out 00:07:30.120 --> 00:07:34.913 over some surface area, that helps it float on the surface. 00:07:37.090 --> 00:07:41.710 Let's try a few more.Look at this egg. It's not a real egg, 00:07:41.710 --> 00:07:43.513 It's a little shaker egg. 00:07:46.680 --> 00:07:48.320 - Maybe it will float. 00:07:48.320 --> 00:07:49.800 - Let's try. 00:07:49.800 --> 00:07:51.593 Ooh, it does float. 00:07:52.940 --> 00:07:54.020 - Wow. 00:07:54.020 --> 00:07:57.760 - And then, this other egg, it's hollow inside. 00:07:57.760 --> 00:07:59.443 So there's air inside. 00:08:01.290 --> 00:08:05.960 - Oh, interesting. It floats right on top. 00:08:05.960 --> 00:08:08.290 The other egg has some shakers in it, 00:08:08.290 --> 00:08:12.600 so it's a little heavier. So it sinks halfway down, 00:08:12.600 --> 00:08:15.710 and just has a little bit peeking out. 00:08:15.710 --> 00:08:19.670 And the egg that's full of air, which is very light, 00:08:19.670 --> 00:08:23.140 those molecules are extra spaced out, 00:08:23.140 --> 00:08:26.160 it's just bobbing along right on top. 00:08:26.160 --> 00:08:28.690 - Exactly, just like Sophie was saying, 00:08:28.690 --> 00:08:29.692 that air is very light. 00:08:29.692 --> 00:08:32.370 That molecules are spread apart 00:08:32.370 --> 00:08:34.190 and this is a hollow egg, 00:08:34.190 --> 00:08:36.460 so there's nothing inside of it except for air. 00:08:36.460 --> 00:08:37.710 So that's why it looks... 00:08:39.820 --> 00:08:42.616 One more, I have this funny brush. 00:08:42.616 --> 00:08:43.793 What do you think? 00:08:45.070 --> 00:08:47.593 What's the prediction on this one? 00:08:51.060 --> 00:08:54.740 - I need to ask our friends. 00:08:54.740 --> 00:08:56.930 Well, one of our friends predicts, 00:08:56.930 --> 00:09:00.820 that this brush will sink to the bottom. 00:09:00.820 --> 00:09:03.403 That it's too heavy to float. 00:09:04.690 --> 00:09:05.823 - Let's try it. 00:09:10.460 --> 00:09:13.900 - Oh wow. Well, it's good that we had a guess, 00:09:13.900 --> 00:09:15.450 and that we had a go 00:09:15.450 --> 00:09:20.210 and it seems like actually, the brush floats! 00:09:20.210 --> 00:09:21.043 - It does. 00:09:23.710 --> 00:09:24.800 That was the last one. 00:09:24.800 --> 00:09:28.520 But I have a very interesting one. 00:09:28.520 --> 00:09:31.193 What do you think will happen with bubbles? 00:09:32.540 --> 00:09:34.440 Should we try the bubbles? 00:09:34.440 --> 00:09:35.950 If I blow bubbles 00:09:35.950 --> 00:09:38.850 and they land on the water, what do you think will happen? 00:09:41.640 --> 00:09:44.010 - Well, it's full of air, 00:09:44.010 --> 00:09:48.863 so they should float on top of the water, but I don't know. 00:09:51.620 --> 00:09:54.373 - Can't even get it onto the water. Let's try again. 00:09:58.900 --> 00:10:02.633 - A few little bubbles are floating on the water. 00:10:05.190 --> 00:10:06.023 - There. We got a big one. 00:10:07.039 --> 00:10:08.739 - A big one, it looks like a dome. 00:10:10.574 --> 00:10:15.260 - Yes, that one has lots of air in it. 00:10:15.260 --> 00:10:16.710 That's floating on the water. 00:10:17.630 --> 00:10:20.970 Thank you friends for playing Sink or Float. 00:10:20.970 --> 00:10:23.163 Just like Kodi and Sandy. 00:10:24.080 --> 00:10:25.973 Should we do some Show and Tell now? 00:10:27.820 --> 00:10:31.050 - Ooh.
