0:03 So, you've decided to undertake the
0:06 extra credit. Here's what you'll need to
0:08 be successful.
0:11 A metric ruler, preferably a meter stick,
0:17 graph paper,
0:20 plain paper,
0:23 a pen or pencil,
0:26 a shorter ruler,
0:29 and a calculator.
0:31 Your first step is to select a room to measure.
0:33 measure.
0:36 I would recommend your bedroom. Any
0:38 small room would be appropriate. You may
0:40 do more than one room, but remember that
0:43 to get at least a 10% increase in your
0:46 grade, you need to have at least 40
0:49 accurate measurements.
0:51 Begin by using your blank piece of paper
0:54 and sketch out a drawing of your room.
0:56 Make sure you include all the exterior
1:01 walls as well as the major furniture.
1:03 If you do not have at least 40
1:05 measurements, you may want to measure
1:08 the distances between furniture and
1:12 windows or doors
1:15 and any other details that you can add.
1:17 Or you may select an additional room to
1:20 do on a separate sheet.
1:23 The next step is to use your drawing and
1:26 enter in the actual measurements of each item.
1:28 item.
1:30 Make sure you measure the length of all
1:34 long walls and the length and width of
1:36 every piece of furniture.
1:38 Record this on your drawing. We will
1:42 then convert this drawing to an actual
1:46 scale drawing using the graph paper.
1:49 For objects less than a meter, note the
1:52 nearest centimeter point. For instance,
1:58 this table is 62 m in length.
2:01 For very short measurements less than 10
2:05 cm, make sure you remember to put a zero
2:07 before the number, such as this
2:18 10 cm would be written as.1 meter.
2:21 meter.
2:23 The next step is to determine the scale
2:26 that you will draw to convert your rough
2:28 illustration to an accurate
2:32 representation on graph paper.
2:35 Notice your two largest measurements,
2:38 the two longest walls in your room. In
2:42 my case, it is 4 75
2:48 You will use these measurements to
2:51 determine how big to draw each item on
2:54 the graph paper.
2:55 The two largest dimensions of the room
2:59 are 4.75 and 3.27.
3:01 I need to make sure that each of these
3:05 fits on the graph paper. My graph paper
3:08 is 20 cm
3:11 by 24 cm.
3:13 Therefore, I need to make sure that the
3:15 largest room measurement fits in the
3:18 smallest measurement on my graph paper.
3:21 To do this, take the graph paper measurement,
3:22 measurement,
3:25 divide it by
3:33 and round this number down. In this
3:37 case, the number would be four. What
3:43 this means is that every meter equals 4
3:52 is 4 cm
3:56 equals 1 meter.
4:00 The next step is to begin converting
4:02 your rough illustration over to an
4:05 accurate scale drawing on the graph paper.
4:07 paper.
4:09 Begin by taking your room's largest
4:14 dimension, 4.75 in my example,
4:22 times your scale. In our example, it's four
4:23 four
4:26 times 4.
4:29 And my answer is 19.
4:31 This means that the longest dimension on
4:35 my room will be 19 cm or 19 blocks.
4:46 and then use your ruler
4:57 Now that you've created your actual
5:00 scale drawing, make sure that the
5:02 original measurements
5:05 for each wall are written in the
5:07 appropriate place on your scale drawing. 4.75
5:10 4.75 m.
5:17 The next step is to measure the other
5:23 wall. In my example, 3.27 27 m and take
5:26 that measurement and multiply that times 4.
5:28 4. 3.27
5:31 3.27
5:33 * 4
5:44 There's 14. Here's 13. 13.08.
5:50 I'm going to go ahead and round that off
5:55 to the nearest 10th. So 13.08 would be 13.1.
5:56 13.1.
6:00 So 13 and just a tiny bit more.
6:05 Use my ruler to draw this line. Make
6:06 sure you use your ruler to draw
6:09 everything in your scale drawing
6:12 accurately to the right scaled size. And again,
6:14 again,
6:24 for that wall. The actual measurement
6:27 that you measured in the room.
6:29 So everything pictured on this illustration
6:31 illustration
6:36 is 4 cm for every meter.
6:38 Continue in this way drawing all your
6:41 external walls and then add in your
6:43 furniture. Again, to get additional
6:45 measurements, you may want to measure
6:47 the distance between pieces of
6:49 furniture, the distance between a piece
6:53 of furniture and a window or a door. All
6:59 Before turning in your final scale
7:01 drawing, you may want to go through the
7:03 checklist. If you do not follow
7:07 directions, you will receive no credit.
7:09 First of all, did you include your name
7:12 and period?
7:14 Do you have a minimum of 40
7:17 measurements? If you have less than 40,
7:26 Do you have actual measurements on your
7:28 scale drawing? And does each measurement
7:32 include the M label next to it? Any
7:34 measurements without M are going to be
7:38 marked wrong. The actual measurements go
7:40 on the scale drawing, not the scaled
7:43 size, but what you actually measured in
7:45 your room.
7:49 Is your drawing actually drawn to scale?
7:51 I should be able to take your scale, do
7:53 the math, and the measurement should be
7:57 a specific size as shown previously.
8:00 Did you label each item? The directions
8:02 say to label every item. For instance,
8:06 the door, the desk.
8:11 Is your scale given? 4 cm equals 1 meter
8:13 is an example of a scale.
8:17 This scale, by the way, is probably
8:20 appropriate for almost every bedroom. If
8:24 you use standard graph paper shown here
8:27 and measure a standard bedroom, 4 cm
8:30 equals 1 meter is a good scale to use.
8:32 Just make sure your scale allows you to
8:36 fit everything on the graph paper. If
8:37 you're still not sure if you met all the
8:40 requirements of the extra credit, just
8:42 bring it in and I'll take a look at it.
