 Okay, now it's time to do the first home activity. Where do you need to go to this home activities folder which is in the main lessons folder. If you go to the lessons folder here and go down on this page and your home activity will start here. Home activity one, home activity two, home activity three. So what we need to do is today start home activity one. I'm going to actually show some more details here because this is the first home activity that we are doing. And we'll be doing this one here, home activity one. So you click on this home activity one and you will see are you ready here. That's the first act in the sense preparation thing that you would be doing here. And if you are clicking on this, it's a pre activity check just to make sure that you have all the prerequisites in terms of computer software. Whether you have them or not, you know, like flash plugin or JavaScript and so on and so forth. So click on this pre activity one. You will see, you know, the activity first thing that you do is check on the flash player here. Check on the flash player. All right. If you click on this check, you have the flash player version to install so your computer will check your flash player. And if it is the latest version, it will say excellent, then you can move on to Adobe reader. Okay. And I can click on open and yes, I am able to read the Adobe one here. So which is pretty good. So I'm I'm okay here. Now I go to the Java enabled script. If it is if it's enabled, we can actually go and check. If not, we will go and you can follow the procedure here how to enable the JavaScript. And if it is there, you know, you can see that how to change that, you know, JavaScript enabling. And after that, we're ready to go submit the data, make sure that it is interacting with the database. This is how you submit your homework or home activities. There is no other way. However, you should retain the paperwork. You don't submit the paperwork, but you should retain the paperwork that you have. Let's say your flavor of ice cream here. I will put vanilla. Okay. And let's see if that is recorded here or not. And I'm going to submit that here. And yes, you're excellent. Your data has been submitted to check your answer. Click on this. Click here. And you should be able to. Yes. You know, it's my name. Patty and your favorite flavor is vanilla. So it is talking to the database. So now I'm good actually. So I'll close this. I'll close this window here and I'll close this window and I don't need this window either here. So now I'm ready to do my home activity here. Okay. When you're doing home activity, I'm going in detail a little bit here, but every activity will be very similar. On the left side here, you would have, on the left side here, you would have the instructions, basically what you need to do here. And this is what it gives. And on the right side is where the house is, is where you would be actually looking at the activity part. First thing that you need to do is view on this. So this is the PDF. Okay. This is the sheet that you will print out. And this is the sheet on which you will work and do all the calculations. And from this sheet, you will copy on to the activity straight away into the computer and submit. So you will keep the sheet for your records until the semester is over. Okay. Until the semester is over. If for any reason, if you want to claim that there was a glitch in the software or something like that, I need to see this paperwork. Otherwise, I will not basically take your activity and grade it. Okay. Now, let's go back here to continue with the activity. And then, so I'm going to continue here. So this is where the activity begins for this activity one. This activity one, our goal is actually to calculate the amount of energy that you use at home. So let's click on the first room here, the bedroom. And then when I see the light switch, I click on the light switch here. And then the room will light up. Okay. So I can click on each of these things here and figure out how many watts each of these appliances would consume. For example, I'll click on this lamp here. Lamp consumes about 40 watts here in the last column. You can see this. This is 40 watts. So I'm going to go and on this activity sheet here, I will write for the lamp here in the third one, I'll put 40 watts. And then you can convert that 40 watts into kilowatts. Each kilowatt is equal to 1,000 watts. So 40 watts is equal to 0.04 kilowatts. Okay. And the wattage you need to get from the other wattages you need to get from this. For example, I click on this air conditioner. So air conditioner is 1,380 watts. So I come back here and write down here 1,380 here. Okay. Now, like that you need to go into each room. For example, here if I go back and if I'm done with, you know, I could click on this printer. I could click on this computer. I could click on this clock radio. I could click on this, you know, light, ceiling light, etc. And then when I'm done with this room, just click on that again and move on to the second room. Okay. So that's how you need to figure out the wattage for each one of those appliances. So let's come back here to this. So once you fill out this watts column, you know, and convert that into kilowatts column in the second column here. And then what you do is you have to estimate here the number of hours you use. That's totally up to you. Air conditioner, typically, you know, you use at night time because it's a room air conditioner. It's stuck, you know, it's fixed on the windows, you know, sill. And you may use it for eight hours or 10 hours when you sleep. So you put the number of hours there. So when you know the power and when you know the time period for which you are operating that when you multiply the two, you get the total kilowatt hours. Okay. For example, on this one here, I could actually put 1.386 kilowatt hours, 1.386 kilowatts. And if I use for 10 hours, that's 13.86 kilowatt hours. And again, clock radio, you have the kilowatts, you have the hours that you use. Clock radio is plugged in 24 hours. So you're using for 24 hours. So you can multiply and get kilowatt hours. Once you add all this column here, okay? So this is in a day that we are estimating. In a day that are 24 hours and 24 hours, clock radio is running in a 24-hour period. Air conditioner is running for eight hours and so on and so forth. So when you add up all this, you will get here the amount of energy used for one day. Okay? So for one day. So now, if I go to the next page here, all right? So total kilowatt hours consumed in one day, the top one would be the sum of all the kilowatt hours of all the appliances. Now, the question is, some of you may be wondering, what if I don't use one of these? If you don't use one or two of these, you can put zeros for the number of hours, which means you don't use any energy for that, for those appliances. And you may have another question. Is refrigerator running for all 24 hours? You may plug in the refrigerator for 24 hours, but it's going to typically use for anywhere between five hours to maybe 18 hours, depending on how old it is and how efficient it is. If it is a very efficient refrigerator, you may get by by running it only for five hours. It won't come on for all 24 hours or consume the energy. So if it's five hours, you can put five hours a day here, or if it is 10 hours, you can put 10 hours. It's up to you. Same is the case with, for example, a freezer if you have at home, or something like that. And also, if you have a water heater here, you know, in the laundry room, that water heater also does not run for 24 hours, although it is plugged in. The number of hours that you use water, running water, times three or so, let's say I run through faucet an hour a day, you know, for everything. You know, for washing hands, for bathing, for washing dishes, for washing clothes, etc. So you should put three hours. If you are using hot water, running hot water for three hours, you should put times three, nine hours. So that's how it goes. And rest of them, if you don't use for one or two appliances, it's okay. You can put CETO. And also, for example, if you are using vacuum cleaner once a week for an hour, you should put every day one seventh of an hour. I'm using one seventh of an hour in a day, and then you can calculate your energy consumption like that. So, now let's get back to the page two here. And then, we'll see. So you have calculated energy for one day here, okay? One day here. And the second day, or second calculation is for one full week here. When you are doing it for one full week, you are going to use one full week is, let's say, for one day, I'm using here 13.56 kilowatt hours. I'm just writing here. This may not be the right number, whatever number you get. When you are doing it for one week, you need to multiply this by seven and then come up with whatever number that you have here. So that may come out to be a certain number. And when you are entering into the computer, your answers back again, you don't have to worry about these decimals. You can probably put that as 13.6, round it off to one decimal, 13.6. But when you are multiplying it by seven here, you use this actual number here and then multiply by seven and then you get here, let's say, whatever number you get here, when you are multiplying by seven, it will be 94 or something like that. I'm just guessing here, 94.65. I'm just thinking about that. So you don't have to actually put 94.65. You can round it off to 94.7 and then you can enter it. But do not round off here and then multiply by seven. You end up with a different number. Now, same thing. The calculation three is for 16 weeks. So you know for one week how much and then you multiply this by 16. So you will get for one full week. Now, once you get that energy consumption for 16 weeks, at the rate of 8.5 cents here, you can see here, 8.5 cents per kilowatt hour, what would be your total cost in a semester? You calculate that and put that over here. So the way you do it is very simple here. 8.5 cents per kilowatt hour and if you are using, let's say, 1,000 kilowatt hours, 1,000 times 8 cents per kilowatt hour will give you the actual cost. Now, the next two questions will be how much energy is consumed by lighting and how much energy is used by appliances. How much energy is used by appliances? To calculate this, you need to go back to page one and figure out here what is your energy consumption for what is your energy consumption for all the lights that you have, all the bulbs that you have. For example, in this one here, we have a ceiling light here, we have a tracking light here, we have a fluorescent light here. So add up all the lights whose purpose is to produce light for visibility. There may be some light that is coming off of a TV. Don't consider that as light, it is. So you can add up all the kilowatt hours that are used by these lighting devices and then you can come up with the fraction of energy that is consumed or percentage. For example, out of 100 kilowatt hours of total energy consumption, if you are consuming 10 kilowatt hours for lighting, then it's 10 percent. So you can write that 10 percent here. Some of you may question, oh, whether I should use it for a day or a month or a week or 16 weeks, it does not matter. The percentages will not change. You can use it in one day or you can use it in seven days or you can use it in 16 weeks, it does not matter. The most important thing in this activity is identify the specific ways in which you can reduce your energy consumption. This is what we are looking at here. This is what we are looking at here. Question number seven. Most of the students, when they lose points, it is on this question. Listen carefully. I do not want any kind of generic one. Okay, I'll reduce four hours on my computer, three hours on this, two hours on that. It will probably save 14 percent of my total energy. That is not what I am expecting. You will lose a lot of points for that one. Okay, so be careful here. Actually, I would advise you to go back to this home activity one here in this folder. Typically, I have here, if we go back to this and see, in each folder, you would typically have a grading rubric here. At the bottom, if you look at, there is a grading rubric here. Okay, the last one, grading rubric. If you open that file, if you open this file here, the grading rubric actually will tell you how the points are distributed. Okay, so watch for this. The table one which you must fill out will be about 25 points and the question seven is 25 points. You will not get all 25 points for writing something there. Okay, not take off a point here or a point there. If you don't write certain things, you will lose a lot of points there. So be careful and listen to this very carefully. Okay, so now let's go back actually to this activity. And let's continue with the activity here. Okay, so after all the rooms here, so this is where you're entering the numbers. So I go here and kilowatts for my air conditioner is 1.386 and I'm using for 10 hours. So this is the table one which is what you must fill this table. Sometimes it so happens that you don't fill the table, but you do all the calculations and then come back to me after this. Oh, I forgot to add, but how could I do all the calculations without doing table one? It does not matter. You can argue all that, but you must fill this table to get complete credit. That's the only way. So here it is 13.86 and so clock radio is 0.04 and I'm using for 24 hours. So my total will be here 0.96. Okay, 0.96. So when I add these up, I mean I can continue to do all for all these appliances and come up with the total for these two appliances. The total is coming out to be about 14.82. I'm going to write here 14.82. Okay, 14.82 and then I'll continue. Of course, you must fill all 24 or whatever appliances you have here. So total energy consumed in here is 14.82 for me, for only two appliances. So I need to calculate for, oh, this is not for one day, this is what we need to do for one week. So I need to multiply this by 7 and I get it for 103.74. Okay, listen to me carefully. When I'm entering these values back in the activity here, I could use 103.7. But when I'm calculating this, I use my full 14.82 times 7. So that's how you should calculate. And then when I'm calculating for 16 weeks, I need to use 103.74 times 16. That'll give me 1659. 1659.84, I can put 0.8 and that's good enough. So when I'm estimating the cost of energy, I calculated at 8.4 kilowatt hours, so I can put that in there. And similarly, percentage of lighting, if it is about 10%, that's about 10% and the rest of it, whatever is not lighting is considered as appliances and devices. So that will be about 90%. When I'm done this, this is the question that I'm actually spending some time here. Identify specific ways. You must address all the appliances, whether you can reduce or not. Listen again. Whether you can reduce or not, you must address all the 25 appliances that you have at home. And you may say the refrigerator and the air conditioner or clock radio, I cannot do anything because I need to plug in for 24 hours. That's perfectly fine. You don't have to reduce your energy, but you must say why you cannot reduce energy. And then you can come back and say, this appliance I can reduce for an hour, that appliance I can reduce for four hours, that comes out to be this much energy. I need to be able to verify all your calculations. So you must give enough details. Giving more details is always better than giving less and saying, well, you didn't ask that. You didn't do this. I'm not writing a legal document here. And there is actually in this folder, if you go into this folder here, there is the rubric. So you want to check this rubric. Make sure that you're addressing all those things. So this question is very important. So after you enter that, you write something in there and you need to check whether the numbers have been entered or not. The best thing I would suggest is, when you're doing calculations, don't sit on angel, log out of angel. Do all your work and then log back in and then again submit. Sometimes it says at the end, server not unable to connect to the server. That is an error. All your work will be down the tubes. So make sure that you connect freshly to angel before you drop in all the data. And then you can click here and actually check all your answers. And if you're happy with all the answers, then you can submit, okay? And you're not done yet. You need to check whether actually your data is recorded in the database or not. If you don't check that, and if it is not recorded properly, there is no decourse for you. So you want to click here and see, I enter two rows here and all two rows I'm able to see when I check. Activity one, check submission. And then you can see all these calculations are showing up. Okay? So you should be able to. If you are not seeing what you are entering or what you had entered before, now is the time you can go back and redo the activity. You don't have to redo every freaking thing. You can just do, you can go back and start the home activity here and you can leave out all the cells where the data is showing up. All you have to do is change the contents in the cells that don't have the data that you wanted. Okay? You don't have to repeat the whole thing. But you, again, you go back here and make sure this check your submission link. You click here and you can check again. Both ways. You can check within the activity and also you can check here by clicking this. Okay? If you don't see anything here and you presume, okay, I clicked it. Probably the instructor would see, no, you are wrong. Instructor will not be able to see or grader will not be able to see if you cannot see. What you see is what we see. So only two rows are entered here. Rest of them are blank. So be careful and keep that in mind. Okay, folks? I think we're ready. I'm giving more instructions than required. But once you check this home activity and you're happy, then you're done, basically. And then you can actually log off and then you're done with the activity. Okay? And then after, you know, typically whatever time period we give you, if we give you one week, you should give us one week for us to grade. If you are given three days to do it in summer times, you need to give us three days to grade it. And after that period, you can click on this graded report and then you can see where you went wrong or what you did wrong or if you have lost any points, where you lost your points. Okay? That's all you need to do. And wish you good luck. Thank you very much.
