1 00:00:10,360 --> 00:00:10,950 All right so 2 00:00:10,950 --> 00:00:15,350 we finished our experimental work it actually went very efficiently today. 3 00:00:17,680 --> 00:00:21,340 Everybody was able to collect data they didn't have any problems with 4 00:00:21,340 --> 00:00:25,490 the procedures it went very efficiently such that they were 5 00:00:25,490 --> 00:00:30,250 all the groups were able to graph all of their data 6 00:00:31,690 --> 00:00:32,310 And. 7 00:00:34,030 --> 00:00:35,500 The data have some interesting. 8 00:00:36,610 --> 00:00:41,450 Features to it. I think the the phenomenon of latent heat we'll be 9 00:00:41,450 --> 00:00:46,410 able to get out of the data, not everything was totally well behaved but 10 00:00:46,410 --> 00:00:48,810 we'll talk about that in terms of doing the procedure. 11 00:00:50,940 --> 00:00:52,330 I think that 12 00:00:53,520 --> 00:00:56,980 The students, they had no problem whatsoever 13 00:00:56,980 --> 00:01:01,370 terms of creating a sensible graph and scaling it carefully. 14 00:01:02,430 --> 00:01:03,960 They were very efficient with that. 15 00:01:05,290 --> 00:01:10,170 I did have the opportunity to ask a couple of the groups about what their data 16 00:01:10,170 --> 00:01:14,900 the patterns in the data and very interesting that one of the things that 17 00:01:14,900 --> 00:01:19,150 did not pop right up was thinking about heat associated with phase change. 18 00:01:20,310 --> 00:01:24,660 And even saying anything about phase change is the process that was happening 19 00:01:24,660 --> 00:01:29,740 here in the data collection is very interesting so as a last go away 20 00:01:29,740 --> 00:01:35,080 I asked them to think about the simulation they did, the FET simulation 21 00:01:35,080 --> 00:01:39,660 which was about states of matter which looked at solid, liquid, gases and 22 00:01:39,660 --> 00:01:45,240 how adding energy moved things towards the gas phase and 23 00:01:45,240 --> 00:01:50,210 removing energy or cooling the system down moved it from gas space 24 00:01:50,210 --> 00:01:54,810 to liquid to solid. I'll be looking to make connections between that particulate 25 00:01:54,810 --> 00:01:59,700 nature of matter representation and the macroscopic data that they had. 26 00:01:59,700 --> 00:02:04,920 The simulation does not get into the quantity of heat that is being exchanged 27 00:02:04,920 --> 00:02:09,910 it does have temperature information but since it's not 28 00:02:09,910 --> 00:02:12,240 Represented in a graphical way in any fashion. 29 00:02:13,320 --> 00:02:18,360 That can't be related to our data so so the simulation doesn't have 30 00:02:18,360 --> 00:02:23,380 that aspect to it. I didn't get it to phase diagrams or anything like that. 31 00:02:26,180 --> 00:02:27,770 So it's clear that the students. 32 00:02:29,400 --> 00:02:32,480 Haven't really taken what we're doing and 33 00:02:32,480 --> 00:02:35,550 made a connection to the particulate nature behavior. 34 00:02:36,840 --> 00:02:40,380 Nothing is come up at all about the fact that the particles may 35 00:02:40,380 --> 00:02:43,090 actually be attracted to each other and 36 00:02:43,090 --> 00:02:48,350 this is even coming from students who have had some other science experiences. 37 00:02:50,100 --> 00:02:55,340 So I'll be very interested to see what our discussion is on Tuesday, my 38 00:02:55,340 --> 00:03:01,850 intention is to give, to take photographs of all of their posters post those and 39 00:03:01,850 --> 00:03:05,480 as part of a homework assignment ask them to look at all the posters so they're 40 00:03:05,480 --> 00:03:09,980 already familiar with everybody's data before they come in on Tuesday. That will 41 00:03:09,980 --> 00:03:14,230 make Tuesday's discussion more efficient and start at the higher level and 42 00:03:14,230 --> 00:03:20,040 I'm going to give them some guiding questions that asked them about relationships 43 00:03:20,040 --> 00:03:23,340 and things that connect it with the simulation so. 44 00:03:24,490 --> 00:03:27,710 By the end of Tuesday I want to come out with being in a position 45 00:03:27,710 --> 00:03:31,350 to either have started getting into the idea of latent heat or 46 00:03:31,350 --> 00:03:35,730 give them some readings to think about in terms of applications of latent heat. 47 00:03:37,530 --> 00:03:42,280 And then relate that back to temperature and energy. I'll also be very interested 48 00:03:42,280 --> 00:03:45,290 in what they have to say during their standing assignments this week. 49 00:03:46,350 --> 00:03:49,670 To see how they may or may not have moved their ideas. 50 00:03:53,710 --> 00:03:54,920 OK that's a wrap.
