1 00:00:01,010 --> 00:00:06,650 Hello, I'm going to do one of the extra activities in Unit 4 2 00:00:06,650 --> 00:00:13,009 It's an ICT activity, extra activity number 1 3 00:00:13,009 --> 00:00:16,589 And I'm going to do one of these activities 4 00:00:16,589 --> 00:00:24,809 Here we have the drawings of each of these electric circuits 5 00:00:24,809 --> 00:00:29,890 And what we have to do in general is to draw currents through the circuits 6 00:00:29,890 --> 00:00:32,630 I'm going to do paper activity number 7 7 00:00:32,630 --> 00:00:37,909 Okay, and for that first I'm going to have a look at the activity in paper 8 00:00:37,909 --> 00:00:41,710 So I'm going to go to the workbook 9 00:00:41,710 --> 00:00:44,270 Here we have the workbook 10 00:00:44,270 --> 00:00:48,109 Here we have the solutions to the activities in the workbook 11 00:00:48,109 --> 00:00:49,990 I'm going to download it 12 00:00:49,990 --> 00:00:53,710 Okay, and have a look at the activity 13 00:00:53,710 --> 00:00:55,909 Activity number 7 14 00:00:55,909 --> 00:01:00,200 Number 7 is here 15 00:01:00,200 --> 00:01:02,719 Okay, it's an extra activity 16 00:01:02,719 --> 00:01:07,640 So, what we have here is the same circuit and a table 17 00:01:07,640 --> 00:01:10,939 The table is to complete 18 00:01:10,939 --> 00:01:15,200 And this way we can explain how this circuit works 19 00:01:15,200 --> 00:01:20,480 We have the battery, one way switch, open or close 20 00:01:20,480 --> 00:01:24,480 The lamp, a lamp, a buzzer 21 00:01:24,480 --> 00:01:26,620 And as well a two-way switch 22 00:01:26,620 --> 00:01:34,459 This control device has to position, position number one, position number two 23 00:01:34,459 --> 00:01:36,219 Now it's in position number two 24 00:01:36,219 --> 00:01:41,840 Let's do the activity now 25 00:01:41,840 --> 00:01:47,159 So, first, it says here that we need to download the images above 26 00:01:47,159 --> 00:01:48,500 These images 27 00:01:48,500 --> 00:01:54,519 And after that, we have to go to this tool and start drawing 28 00:01:54,519 --> 00:02:00,780 Ok, I'm going to download this image for the activity number 7 29 00:02:00,780 --> 00:02:04,019 So I right click on the image 30 00:02:04,019 --> 00:02:06,540 Guardar imagen como 31 00:02:06,540 --> 00:02:11,539 And I download the image to Descargas 32 00:02:11,539 --> 00:02:12,800 Guardar 33 00:02:12,800 --> 00:02:17,699 And now I'm going to go to the tool 34 00:02:17,699 --> 00:02:19,000 Draw island 35 00:02:19,000 --> 00:02:21,159 This is the tool 36 00:02:21,159 --> 00:02:28,919 And the first thing I have to do is to upload, to import the circuit, my image 37 00:02:28,919 --> 00:02:32,960 So I click here, this is my image 38 00:02:32,960 --> 00:02:38,840 And now I can start drawing 39 00:02:38,840 --> 00:02:47,439 Ok, for that I'm going to use lines instead of freehand drawing 40 00:02:47,439 --> 00:02:51,400 Line, I'm going to choose the color 41 00:02:51,400 --> 00:02:55,060 red, and the size 42 00:02:55,060 --> 00:02:59,860 ok, it says in the activity 43 00:02:59,860 --> 00:03:04,099 that we need to have our two-way switch 44 00:03:04,099 --> 00:03:07,860 in position number two, sorry, in position number one 45 00:03:07,860 --> 00:03:11,979 so position number one is this, so this cable 46 00:03:11,979 --> 00:03:14,639 has to be connected to this other cable 47 00:03:14,639 --> 00:03:20,379 ok, I'm going to draw the current through the wires 48 00:03:20,379 --> 00:03:24,599 drawing on the line, so I draw this 49 00:03:24,599 --> 00:03:30,849 this way, ok 50 00:03:30,849 --> 00:03:35,389 ok, it doesn't matter if it's not 51 00:03:35,389 --> 00:03:38,009 precise 52 00:03:38,009 --> 00:03:43,509 my lines, ok, continue 53 00:03:43,509 --> 00:03:46,590 through the buzzer, ok 54 00:03:46,590 --> 00:03:50,449 now the current goes down 55 00:03:50,449 --> 00:03:57,400 here, and there 56 00:03:57,400 --> 00:04:00,680 of course this switch has to be closed 57 00:04:00,680 --> 00:04:05,159 otherwise we don't have any current through the circuit 58 00:04:05,159 --> 00:04:13,750 ok, so 59 00:04:13,750 --> 00:04:16,850 that is the 60 00:04:16,850 --> 00:04:21,509 pathway the current follows 61 00:04:21,509 --> 00:04:25,610 I am going to draw here a kind of arrow to indicate 62 00:04:25,610 --> 00:04:31,610 that the current always comes out of the positive terminal of the battery 63 00:04:31,610 --> 00:04:40,009 ok, this way as well, one of two I think is enough 64 00:04:40,009 --> 00:04:49,860 this way, and the last one 65 00:04:49,860 --> 00:04:57,160 here, ok 66 00:04:57,160 --> 00:05:01,160 and in the activity says as well we need to 67 00:05:01,160 --> 00:05:05,160 draw our names, ok 68 00:05:05,160 --> 00:05:09,160 that is not an individual activity 69 00:05:09,160 --> 00:05:13,160 so you can work together at home as well 70 00:05:13,160 --> 00:05:17,160 to draw our names, to write our names 71 00:05:17,160 --> 00:05:21,160 we have here a tool, it says 72 00:05:21,160 --> 00:05:25,160 text, so I click here text 73 00:05:25,160 --> 00:05:29,160 open a rectangle, and my name, teacher 74 00:05:29,160 --> 00:05:33,160 ok, and now 75 00:05:33,160 --> 00:05:37,160 what I can do is to download 76 00:05:37,160 --> 00:05:41,160 I don't need to take a screenshot of this image 77 00:05:41,160 --> 00:05:45,160 because here we have a tool that it says 78 00:05:45,160 --> 00:05:49,160 save, so I can download to my computer this 79 00:05:49,160 --> 00:05:53,160 image, my circuit, I click on save 80 00:05:53,160 --> 00:05:57,160 first it says the name is draw island 81 00:05:57,160 --> 00:06:01,160 but I can change it later 82 00:06:01,160 --> 00:06:16,560 Okay, I'm going to go to the scarvers, draw island, here I can rename my file, teacher 83 00:06:16,560 --> 00:06:23,100 and I double click to see what I have and this image is the image I have to upload to 84 00:06:23,100 --> 00:06:26,920 our Google Classroom, okay? 85 00:06:26,920 --> 00:06:30,660 I think it's enough. 86 00:06:30,660 --> 00:06:31,319 So thank you.
