1 00:00:02,520 --> 00:00:07,879 hello my name is Pilar and I'm going to explain you how to design an activity 2 00:00:07,879 --> 00:00:14,900 for an inquiry based learning system I would like to share this video with you 3 00:00:14,900 --> 00:00:20,600 because I found that nowadays there are many teachers that try to change this 4 00:00:20,600 --> 00:00:29,359 way of learning into this one which is similar to what they are going to find 5 00:00:29,359 --> 00:00:38,159 when they get to work. They will work in a team probably and it's pretty sure 6 00:00:38,159 --> 00:00:42,820 they will have to explain their conclusions in front of their colleagues 7 00:00:42,820 --> 00:00:51,350 so it's better to train them from high school to do this. What happens? The 8 00:00:51,350 --> 00:00:59,049 teachers go into the class with a big idea, a very good experiment, an amazing 9 00:00:59,049 --> 00:01:03,670 lab that he thinks that will really interest his students and make them 10 00:01:03,670 --> 00:01:10,209 learn and make them have fun but students are not used to this kind of 11 00:01:10,209 --> 00:01:20,590 methodology and sometimes they don't know what to do and the activity has not 12 00:01:20,590 --> 00:01:32,430 the result the teacher expects and it leads to his disappointment. To avoid this let's see how to 13 00:01:32,430 --> 00:01:40,959 improve our activities with an example. But if you want to learn more of the inquiry-based learning 14 00:01:40,959 --> 00:01:48,799 methodology just visit this website inquiry-based science learning in wordpress and there you can 15 00:01:48,799 --> 00:01:54,799 find more about this methodology as well as resources in science and more 16 00:01:54,799 --> 00:02:03,859 examples in chemistry and in physics. This was the first exercise I did and 17 00:02:03,859 --> 00:02:13,639 what we realized is that there is a big mistake. The carbon is not red, it's gray 18 00:02:13,639 --> 00:02:22,800 and the red atoms are oxygen. Why did I leave this big mistake in this video? 19 00:02:22,800 --> 00:02:28,099 It's because I think it's really important that we make a culture of a 20 00:02:28,099 --> 00:02:35,180 mistake as an opportunity, a very worthy opportunity to learn. Our students 21 00:02:35,180 --> 00:02:41,139 shouldn't be afraid to make mistakes in front of their classmates. Instead of 22 00:02:41,139 --> 00:02:47,139 that we should encourage them to feel free to make any mistakes so that's the 23 00:02:47,139 --> 00:02:58,219 way that the rest of the classmates can learn more well after that we see that 24 00:02:58,219 --> 00:03:03,460 they have to calculate molecular masses it's a good idea with the models here 25 00:03:03,460 --> 00:03:15,219 it's easier for them but we found a better way to display the results with a table now it's 26 00:03:15,219 --> 00:03:21,860 clear and also we have included a new row with the mass of one molecule in grams they need 27 00:03:24,819 --> 00:03:32,580 this in order to calculate it because although it's inquiry based learning they need knowledge 28 00:03:32,580 --> 00:03:45,280 to do their calculations and we can give them the data and then they can calculate it and they can 29 00:03:45,280 --> 00:03:54,550 see how light an atom is and it will help them with the next exercise. In this exercise I asked 30 00:03:54,550 --> 00:04:04,469 to say a number guess a number of atoms or molecules that we need to be able to weight 31 00:04:04,469 --> 00:04:13,110 them without a balance what we find is that it was confusing because as i give the example with 32 00:04:13,110 --> 00:04:22,629 an atom of hydrogen if they suddenly try to guess the number of hydrogens if one gram of 33 00:04:22,629 --> 00:04:30,430 hydrogen they will find a number really close to the Avogadro's number and that wasn't what I 34 00:04:30,430 --> 00:04:40,220 really want so we see that it wasn't clear if they had to calculate it for each substance 35 00:04:40,220 --> 00:04:50,500 on for all of them and then we find that it's clearer to give them this tip they can write 36 00:04:50,500 --> 00:04:59,500 their answers here but they have a wide space to make their calculations. With 37 00:04:59,500 --> 00:05:07,420 exercise 3 I gave them the Avogadro's number and this time it's easier to 38 00:05:07,420 --> 00:05:14,259 make them calculate it that they will be more angry and that's what we did with 39 00:05:14,259 --> 00:05:20,000 this exercise here. How many atoms are there in 12 grams of carbon? Now they 40 00:05:20,000 --> 00:05:24,980 calculate the Avogadro's number using the definition of MOF. You can see that 41 00:05:24,980 --> 00:05:33,259 this is part two of the worksheet. The first one was a guess, now they explore 42 00:05:33,259 --> 00:05:41,899 if their guessing was right and useful enough. That's why we have this 43 00:05:41,899 --> 00:05:49,100 question here. This question helps the student to think deeply about what they 44 00:05:49,100 --> 00:05:56,519 have calculate and it guides them in order to not need the teacher 45 00:05:56,519 --> 00:06:03,500 explanation they have they can think deeply as I said which sometimes it's 46 00:06:03,500 --> 00:06:11,180 difficult to get with our students now in the exercise for they had to present 47 00:06:11,180 --> 00:06:18,980 the results in these tables but this data here wasn't really necessary it's 48 00:06:18,980 --> 00:06:24,079 pointless to calculate the mass of one molecule they had done it already and 49 00:06:24,079 --> 00:06:30,439 it's pointless to calculate the mass in atomic mass units of huge amount of 50 00:06:30,439 --> 00:06:37,399 molecules so we need just these three items and it's easier to present it like 51 00:06:37,399 --> 00:06:45,279 this and also you can see a funny image that will engage our students of this 52 00:06:45,279 --> 00:06:53,540 strange animal called mole. Now we have the results here and they will see 53 00:06:53,540 --> 00:06:59,160 the coincidence between the mass of one molecule in atomic units 54 00:06:59,160 --> 00:07:08,120 and the mass of a mole in grams and then we agree they will realize also that it 55 00:07:08,120 --> 00:07:16,379 doesn't happen with any other amount of molecules now they know that they can go 56 00:07:16,379 --> 00:07:21,959 further and try to do the same with an element this is an open question they 57 00:07:21,959 --> 00:07:30,959 can think in different metals and have different results but they will all find 58 00:07:30,959 --> 00:07:39,199 that the mass in atomic units it's the same of the mass of one mole in grams I 59 00:07:39,199 --> 00:07:46,920 had this question here but I find that it's better to ask it later as a 60 00:07:46,920 --> 00:07:53,399 a reflection that allows the student to go back, explain the concept with their 61 00:07:53,399 --> 00:07:59,399 own words and assimilate it. When I explained my worksheet in front of my 62 00:07:59,399 --> 00:08:05,879 colleagues, some of them pointed that with this question the concept of mole 63 00:08:05,879 --> 00:08:10,420 as a multiplier wasn't really clear because it seems that it can be used 64 00:08:10,420 --> 00:08:18,180 just for atoms and molecules that's what we change this exercise into the 65 00:08:18,180 --> 00:08:24,519 exercise 5 with different metal that's very I find it very useful because they 66 00:08:24,519 --> 00:08:30,220 can explain the results a one students to others and because the metal is 67 00:08:30,220 --> 00:08:36,980 different the result will be different so it's not as when we correct an 68 00:08:36,980 --> 00:08:44,840 exercise in our board that sometimes our students don't pay attention because 69 00:08:44,840 --> 00:08:50,480 they know the result but this time the method will be another method so it's 70 00:08:50,480 --> 00:08:57,320 different so something more interesting and they have the reflection to explain 71 00:08:57,320 --> 00:09:01,700 the concept of a mall which is very interesting to see if the student have 72 00:09:01,700 --> 00:09:08,740 understood has understood the concept and also there's a new question to 73 00:09:08,740 --> 00:09:19,940 extend the concept of mall to any object a mall of tables a mall of footballs in 74 00:09:19,940 --> 00:09:28,960 a game a mall of players so they can think further about it well what have we 75 00:09:28,960 --> 00:09:33,139 learned today this is a very good question to make every day in an 76 00:09:33,139 --> 00:09:37,779 inquiry-based learning system. We have learned that it's very important to 77 00:09:37,779 --> 00:09:45,240 clarify the objectives before making the activity. We have learned that it's 78 00:09:45,240 --> 00:09:49,659 better to do questions that the student can't solve without the help of the 79 00:09:49,659 --> 00:09:56,000 teacher. It's better to try to make them find the data instead of giving it 80 00:09:56,000 --> 00:10:02,240 directly as far as it's possible and as far as you can as well use anything you 81 00:10:02,240 --> 00:10:09,360 find to engage their attention like the picture of the mall and I really 82 00:10:09,360 --> 00:10:15,820 encourage you to give open exercise as the one with the metal that the students 83 00:10:15,820 --> 00:10:20,960 do their calculations with different metals so they reach to different 84 00:10:20,960 --> 00:10:27,039 solution and they can explain and share one student to the rest of the students 85 00:10:27,039 --> 00:10:35,120 and finally include a reflection to help them to simulate the concept that's all 86 00:10:35,120 --> 00:10:42,379 for today I really hope this will help you and I encourage to include this 87 00:10:42,379 --> 00:10:48,019 methodology in your classes thank you very much for your attention
