This eighth-grade science lesson focuses on weather maps. It is the 20th lesson in a sequence of 20 lessons on meteorology. The lesson is 56 minutes in duration. There are 25 students in the class.

00:00:11Okay. The bells are kind of messed up so we will- I will probably just go ahead and dismiss you. We're now starting like five minutes late,
00:00:19because they didn't get the bells working right.
00:00:22All right, who is absent? Anybody?
00:00:25I don't know.
00:00:27You don't know? Do you know who sits at your table normally?
00:00:31//He's missing. Who is he?
00:00:32//I don't know who is supposed to-
00:00:33Devin is not here.
00:00:34No. He's //here.
00:00:34//Devin is gone.
00:00:35He's here.
00:00:36Right. He's here.
00:00:41Jessica, I'm gonna have you move to-
00:00:47Yeah, a table of three people, not the one that's got four.
00:00:52All right, so nobody is absent? Everybody is here?
00:01:04Um, I'm not going to return your papers today. I'll save that for tomorrow. We'll get right into what we're going to be talking about today.
00:01:13There's just a couple of things that I needed to go over with you first that I'm not sure that you got it before.
00:01:22Yes? Writing your homework books? Okay.
00:01:29All right. Open up your book. What?
00:01:34I can't hear out of my ear.
00:01:35What's wrong?
00:01:36It hurts.
00:01:38Did you ever go to the doctor?
00:01:40Miss A, (inaudible).
00:01:42Okay. Take these right here. Go. Bye. They must feel like they have the plague or something.
00:01:52All right. You ready?
00:01:54Okay. On page- open your book to page 588.
00:01:58There are-
00:02:06some weather maps. There's actually four weather maps on those pages that are in front of you.
00:02:11They are showing a progression of weather over a four-day period? Three-day period, okay. Where the weather is going.
00:02:21Looking at those four maps, looking at the one on the page before that- flip one page back-
00:02:32Okay? And looking on the page after that- flip two pages, forward-
00:02:42So you're looking at page 587, 88, 89, and 90- find the high pressure centers;
00:02:57find the low pressure centers,
00:03:02on any one of those five or six maps,
00:03:06find the cold fronts and the warm fronts.
00:03:11Okay, now here's a puzzle for you. What do you notice about fronts and pressure centers?
00:03:19What do you notice about the fronts and the high pressure; and the fronts and the low pressure?
00:03:26Look- and you gotta look at the map in order to answer the question.
00:03:31And if you can't figure it out with one map, move to another map.
00:03:37Make some comparisons.
00:03:39What pattern do you notice about fronts and pressure centers?
00:03:55I have a question.
00:03:55Mm. No- no, no. I'm waiting.
00:03:59I have a question.
00:03:59Oh. Question? Okay.
00:04:01Aren't the pointed ones the warm fronts?
00:04:03The pointed ones are the cold fronts.
00:04:06Okay. I was just making sure.
00:04:11I thought you were gonna answer the question. I am waiting for some people to get that look on their face, like, "oh."
00:04:22Stuart, are you noticing anything?
00:04:28Is there something you're noticing about the high pressure centers that is not the same as the low pressure centers?
00:04:41Besides the- besides the points?
00:04:44Besides the what?
00:04:45The points, the triangle-
00:04:47What about the points?
00:04:49That there's like more(inaudible)-
00:04:52There's no triangles where?
00:04:53No. There's more triangles-
00:04:55Than there's (inaudible).
00:04:58Oh. Okay. So there's more cold fronts than warm fronts?
00:05:01Okay, but what about the low pressure centers and what about the high pressure centers?
00:05:15Mike, what do you think?
00:05:16I think that there's low pressure centers on the cold fronts and the warm fronts too. Like on a front //there's like a-
00:05:23//And what about the high pressure centers?
00:05:26They are moving away from the front.
00:05:28They don't seem to have fronts attached to them, do they?
00:05:33You notice that, John?
00:05:34Look at all the low pressure centers. Do you see fronts attached to them?
00:05:40No. Can you tell me why? Remember the balloon thing? Can you tell me why? John, what do you think?
00:05:49Uh, when it hits the hot air, it would like go above it. Like-
00:05:56So you got a warm air mass and a cold air mass?
00:05:58Yes. And when it hits- I remember, but- I remember it, but it's hard to explain.
00:06:06Okay. You're saying the warm air rises above that cold air?
00:06:11And the-
00:06:15And the warm air has what kind of pressure?
00:06:18Low pressure.
00:06:19Okay. Mark, did you have something to add?
00:06:21No. I was gonna say (inaudible).
00:06:24Okay. Let me show you a real easy way to really kind of understand it. I have three balloons this time, and they are different color. Red is?
00:06:36Warm air. Blue is?
00:06:38Cold, and yellow is?
00:06:40Is cooler. Let's say cooler. All right. Let's look up here for a second.
00:06:47And you'll even notice on this map there aren't any fronts attached to those low pressure centers, right?
00:06:53Just- or to the high pressure centers. Just to the low pressure centers, right?
00:06:58Okay. So where would the red balloon go? If this is the- what kind of front?
00:07:04Cold front.
00:07:05Then where's the warm air going to be?
00:07:07Going behind it.
00:07:09Behind it? This is the front of a warm air mass?
00:07:12Uh, no. It's gonna be in front of it.
00:07:14It's gonna be in front of it?
00:07:15Okay. Where's the cold air gonna be?
00:07:17Behind it
00:07:18Behind it. And we'll put the yellow air up here, okay? This is where the low pressure center happens. Watch what happens.
00:07:25Here's the warm air. Here's the cold air. Here's the cool air. You see the hole in between the three?
00:07:33There's your low pressure center. It's where those big bubbles of air have a depression, or an area, a gap, that space,
00:07:42that's the low. See? Yeah.
00:07:46Ah. Okay? That's what you're looking at. You're looking at that bubble of warm air, the bubble of cold air behind.
00:07:53Here's the front right here, right? The front of the air mass, yes?
00:07:57And then where they all meet up- where these bubbles of air meet up, that's where that low pressure center comes in.
00:08:03The high pressure is going to be this big bubble of cold air at the very highest point of it as far as pressure goes.
00:08:14It's not gonna ever have a front because it occurs in like the middle of the air mass, okay?
00:08:20Get it?
00:08:21Ooh. Yes?
00:08:23So then basically a tornado would be caused because of low pressure in the (inaudible)?
00:08:30Yes. That depression of low pressure air, right. What you got is air funneling in and air funneling up at the same time,
00:08:38and then once it starts to twist- when we see that video on "Understanding Weather,"
00:08:43it's really cool because it shows the air funneling like this on the ground. What's that called?
00:08:51Convection current.
00:08:52Right. It shows that on the ground like a big tube doing that, and then when that- I think it showed cold air- hits it- excuse me- hits it,
00:09:02it- remember when I said the cold air hits that blue and the blue goes flying off- or the-
00:09:08Cold air hits the red and the warm air goes flying up? That's what causes the storm?
00:09:12What it shows is that that tube gets split and splits up this way, and that's the beginning of a funnel cloud. It's very cool.
00:09:21But you'll see that on the, uh, video. Okay. So does that help with low pressure and high pressure and-
00:09:27//Okay? Kind of a visual.
00:09:29Okay. The reason you need to know that is because this is what you are going to be doing.
00:09:35First hour did not even finish the cities on their map which was kind of disappointing. I thought they'd get further than that.
00:09:43You do not need- and I won't let you use- your book or your notes. I was going to let you, and then I thought,
00:09:51"No, I think that you need to get that station model plugged into your head a little better than you have it."
00:09:57Okay? So you don't need any of that. You may use the map on page 770, I think. Check page 770 in your book.
00:10:12There should be, yep, a map of the United States. You also have a map like this at your table with all of the cities on it.
00:10:20Oh. They don't have one down there.
00:10:22Hannah, would- would you take that map down to the office and ask them to give it to the kids inside the conference room?
00:10:32Okay? I think they brought the map back from their- and then tell them to leave it there. Leave the pencils and the map, okay?
00:10:39All right, so you've got enough reference for finding certain cities. You're going to get a list of 12 cities in the United States.
00:10:47Oh, that stays on; this goes off.
00:10:49A list of 12 cities in the United States, with some other data. I told you this last week.
00:10:55And you're going to get a blank map that- handing out?
00:11:03Okay. Handing out?
00:11:05Here. (inaudible)
00:11:06Yeah. Daniel.
00:11:07I want to let Daniel do it, because she threw her hand out there first. I didn't think she wanted to get up, but she does.
00:11:13Okay. You're gonna get a sheet like this, that has all of the instructions that you need on it.
00:11:18What you are going to do is, on the map, in front of you- and put all your notes away right now-
00:11:24any notes, any... You can only have your book open at page 770.
00:11:45Okay. On the blue sheet is a list of the 12 cities, around the country. You might wanna make note that-
00:11:54Hatteras, fourth from the bottom, is actually called "Cape Hatteras";
00:12:01most of you have probably never heard of it. You will, though, by the time we get done with oceans.
00:12:07It is in North Carolina. North Carolina.
00:12:12I'm not gonna show you where that is; you ought to know where North Carolina is.
00:12:17And, uh, Kansas City. There are two big Kansas Cities. We're talking about- thank you- Kansas City, Missouri. Okay?
00:12:26So you might wanna write "MO" after Kansas City, just so you remember where it's from.
00:12:38All right, who wants to read the directions? I'm gonna stop you a lot as you go through, and explain certain things.
00:12:43Mark, go ahead.
00:12:45"Locate and label each of the above cities on the attachment."
00:12:48Okay. The first thing you're going to do is find the cities, one at the time. Detroit, okay?
00:12:54When you find it on the map, you're gonna put the little dot where Detroit goes.
00:13:02Then you're gonna write "Detroit," but you've got to write small, and you've got to write neat, so that I can read it.
00:13:08Stuart, you haven't started yet, have you?
00:13:10Don't, because I- I've got to tell you the whole thing.
00:13:15Remember where Detroit goes on a station- a weather station model, right?
00:13:21Many of you forgot to put "Weather City" when you had to redo another station model on that worksheet.
00:13:27Lots of people did not put that city name. They put all the other stuff but didn't put the city.
00:13:32So when you write "Detroit," to the left of it make your circle right away and start building that station model.
00:13:42Otherwise, if you go through and write all the cities first, then you're gonna have to go back and make sure you've got room to put the station model.
00:13:50So do one city at a time, okay? Do you know what I'm saying?
00:13:53You got it? Yes?
00:13:56Like this. I'll just start this first one just so you know.
00:13:59If you have got this part of Michigan right here, and you put the dot, you need to write "Detroit" over here, okay?
00:14:10And then start your station model right here.
00:14:15All right? A reminder that the wind direction is that arrow to the middle.
00:14:22All right? And- I'm trying to think what else they had trouble with. They had a little trouble last hour with cloud coverage in the circle.
00:14:31If you're not sure, ask someone at your table first before I come around to help you with that. Make sure you get it before-
00:14:37or somebody else- you've asked somebody else before you ask me, okay?
00:14:43Because you had the 25%, you had the 50%, and you had the 75% then you had full coverage.
00:14:47Remember what those meant because that's how they are on this sheet, okay? Okay. So there's your- any questions on the station model?
00:14:58You know where everything goes on there? There are only two cities with current conditions, and I'll put the symbols on the board.
00:15:04They're very simple, okay? So you don't need that chart either. Okay. Next one. Mark, keep going.
00:15:12"Construct a weather station map for each of the above cities. Place them at approximate locations."
00:15:18Appropriate locations.
00:15:21//Yep. All right. Now, that's as far as everybody got for second hour, okay? Go ahead and read on, Mark.
00:15:27Place high and low pressure centers where you think that- where you think they would be located on the map.
00:15:33You're gonna have to look at what in order to do that? What's some indicators of high and low pressure?
00:15:41Oh, no. You know what we thought of last hour? Don't do this one. Put an arrow, four, five, and five to four.
00:15:48Do step five first. It'll make four a lot easier. Or three and four. I'm sorry. I'm sorry. Wait, wait, wait.
00:15:55Do step four first and then go back up and do step three. Read step four, Mark, so I can explain what I mean there.
00:16:06Shade regions of precipitation. Place symbol for cold and warm fronts where they would most- most likely be located on the map.
00:16:15Okay. Do you see why I said to do this one first?
00:16:18When you find the areas of precipitation and then you find the cold and warm fronts,
00:16:25it should be a lot easier to put the low pressure and high pressure centers, right? Okay.
00:16:30So do number four first and then go back and do number three. When you shade for precipitation
00:16:39:if it's light rain, it's a light green; if it's medium rain, if they just say rain, then it's a yellow; and if it's a thunderstorm, then it's red.
00:16:48That's how the Doppler Radar satellite picture picks it up, okay? It's the density of the air is what they pick up, all right?
00:16:57Okay. Go ahead, Mark.
00:16:58Answer the following questions. Interpret the data using your (map weather).
00:17:04Explain the locations of high and low pressure centers in warm and cool fronts.
00:17:11Are there any environmental or severe weather incidents that may occur? Include the weather indications in the map.
00:17:20Use your weather map to explain the above answer.
00:17:24Okay. This will be on a separate sheet of paper- probably won't get it until about the middle of class tomorrow-
00:17:29where now you have to explain why you put everything on your map where you put it, okay?
00:17:35So you're kind of explaining yourself: low pressure, high pressure. And hopefully you'll be able to do that.
00:17:41I think you can, if you allow yourself to think in that direction. Okay, and then six.
00:17:49"Using the data on the weather, forecast the weather for October 24th, 2002, for each of the cities of the (inaudible)-
00:17:58Okay. Are there any questions about what I expect you to do? No?
00:18:06So I will be able to just sit here the whole time you're doing this and just watch you like last hour? Todd?
00:18:15I don't get "shade regions of precipitation."
00:18:19Okay. On the map that you had to do for the weather station models, they told you to shade the areas of precipitation.
00:18:25The same way that this map did- you see how they shaded these areas? Where it's raining.
00:18:33And once you get done with all your station models, you'll be able to see it better.
00:18:36You'll look for the cloudy areas, and then from that you'll look for the rainy areas.
00:18:40Now I know, I just- I thought you meant to do four completely first.
00:18:44No. No. Well, yeah. You're gonna do four first before you do three.
00:18:49I know that, but I thought-
00:18:50Oh, no. Not before two though, right. Okay. Got ya.
00:18:54Do you work as a group or-
00:18:55You work as a group, yes.
00:18:57Which means talking quietly about the mapping activity, not about what you did over the weekend, okay?
00:19:07Yes, Wes?
00:19:07I'm really not sure about these, uh, models we have to put down.
00:19:16I don't quite understand them.
00:19:14Did you do that worksheet last week?
00:19:16Which one?
00:19:17The one that you were supposed to turn in for a grade on Friday.
00:19:20I'm not sure.
00:19:21You had "weather city" and then "around the circle" which had cloudiness in it.
00:19:29I don't remember anything like that. I remember most of last week.
00:19:32All right, I'm not sure you turned it in.
00:19:34I'm not sure either.
00:19:36Okay. We'll see what your group can help you with.
00:19:42I was wondering if I could move right next to Geoffrey so we-
00:19:46Sure. Mark?
00:19:47When we're like doing Detroit, you said- do you want us to write-
00:19:51like go through and write all the cities and then go and do the weather stations, or do the city and then the weather station?
00:19:56Somebody want to answer Mark's question?
00:19:59Do the weather- the city and the weather station together.
00:20:04Don't go- don't do all the cities first and then go back and do the stations because you might write the name of the city in the wrong place,
00:20:10and you won't be able to fit the weather station around it. Hannah?
00:20:14Okay. What do we do for, like, the current conditions?
00:20:20Okay. There are only two. Thanks for that. There are only two. Let me pull this up.
00:20:28They call it on those dir- and that's actual data information from last Wednesday, the 23rd, straight off the Weather Channel.
00:20:36When you're all done, I'm going to give you the actual satellite map with the warm fronts and cold fronts and high and low pressures.
00:20:43You're gonna compare that to what you came up with on your map. I'm looking at probably Wednesday by the time we get to that.
00:20:52Then you're- you're gonna forecast at the bottom. Your last step is gonna be a forecast.
00:20:56Then you're gonna look at what happened the next day and see how well your forecast came out, okay?
00:21:01Uh, but on the Weather Channel, instead of calling it intermittent rain, they call it light rain. So this is the symbol for light rain.
00:21:10I know it's tough, and I don't know if you're gonna be able to remember it, but that's light rain, okay?
00:21:17There are no thunderstorms, none of that, all the fancy stuff they had on that chart. And guess what this is?
00:21:25Light snow.
00:21:26If it were heavy snow, there would be two of them. Oops. Okay?
00:21:34Any other questions? Yes, Wes?
00:21:38So if it was heavy rain, there would be two //little footnotes?
00:21:41//Two dots, yep. Yep.
00:21:44Can I have a pencil? I only brought a pen.
00:21:47Yeah. If you need a pencil, let me know. Don't try to do this in pen. It's too- too much erasing going on.
00:21:54Yes, Mitch? Question?
00:21:55When we shade these, what colors did they- do you want us to have them?
00:21:59I have a box of pencils right up- colored pencils. I did. Right up here. Whatever color you want except red or blue.
00:22:08Oops. You needed this.
00:22:11Whatever color you want except red or blue, okay? All right. If there are no more questions, get started.
00:22:20I'm gonna put this away so I don't trip on it.
00:22:29I need a pencil.
00:22:29Okay. Go back over there and get one from where I got it, top- that little top drawer. Mark, did you have a question?
00:22:35I don't like sitting next to a wall.
00:22:43On the wall? Do you want me to move you up here?
00:22:47No, that's all right.
00:22:47Oh. I thought so. Christina?
00:22:50Can I sharpen my pencil?
00:22:51Yes, you may sharpen your pencil.
00:22:53Can I sharpen my pencil, too?
00:22:55Yeah. You guys are supposed to do this beforehand.
00:23:05Okay. Let's see if I can talk you through this. You wrote "the city of Detroit."
00:23:10And then there was a circle next to it so just draw a circle, a relatively large circle.
00:23:18Okay. Now- no. Don't fill it in. Just a //circle.
00:23:22And I just said "use a pencil." Is that a pencil?
00:23:24Oh. That's a cool pencil. Okay. An open circle. Now, in the circle you have four choices.
00:23:35These are your choices: mostly sunny- no. Clear, mostly sunny, partly cloudy, mostly cloudy, cloudy. That's it. Five of them. Okay?
00:23:48That would be cloudy, wouldn't it?
00:23:50And they are- it's saying cloudy. And they are represented by how much you shade that circle.
00:23:55So that would be about 50% probably?
00:23:57Actually, cloudy is gonna be all shaded.
00:24:03And let me see your pencil for a minute, and I'll draw them on the back so you can- all right.
00:24:08This one is totally unshaded so that's going to be what?
00:24:13Uh, sunny.
00:24:14Clear. Yeah. Sunny or clear. This one is gonna be a quarter shaded.
00:24:19This one is gonna be- let's do them all first and then you can compare. This one is gonna be this way.
00:24:28And that one is gonna be completely- and you know this one's cloudy and this one's clear.
00:24:32Okay? So now your other options are mostly cloudy, mostly sunny or partly cloudy.
00:24:40Okay. So that would be sunny, partly- that would be sunny, that would be partly cloudy, mostly cloudy, right? No. No.
00:24:51Okay. If-
00:24:52//Oh, boy.
00:24:53//That's all right. Relax. If that's clear, then this is like mostly clear or mostly?
00:25:01S :00]
00:25:02Mostly clear or mostly? If this one's sunny-
00:25:08Mostly sunny.
00:25:08Okay. This one is mostly sunny. Now you've got mostly cloudy and partly cloudy and these two left.
00:25:16Which one's mostly cloudy and which one's partly cloudy? What's that one?
00:25:20Mostly cloudy.
00:25:22What's that one?
00:25:22Partly cloudy.
00:25:23Okay. So you've got-
00:25:26Sunny, clear.
00:25:27Yeah. Sunny or clear.
00:25:30Mostly sunny, partly cloudy, mostly cloudy, cloudy.
00:25:35Detroit was easy, but you're gonna get to some other ones that- okay?
00:25:40All right, now, the next thing that you have to figure out is where the temperature goes and where the dew point goes.
00:25:46You guys, you have humidity information. Does it go on the weather station model anywhere?
00:25:54No. We didn't put humidity on there, did we?
00:25:57So I don't need-
00:25:58Well, just- you don't need it right now. You'll need it to answer some questions, but you don't need it on the weather station model. Mark?
00:26:04For Detroit how is eight mile an hour- (you got us around 10).
00:26:08Eight-mile-an-hour wind- I told you last week, your choice. It's either a five- you listening, Geoffrey?
00:26:15Eight-mile-an-hour wind is either a five or a 10. Your choice.
00:26:20If you show me three long lines there, I'm gonna know you didn't know what you were doing, okay? All right.
00:26:27Do you remember where temperature went?
00:26:31Right above it.
00:26:34Yeah. Right above it to the left.
00:26:42Okay. And then dew point went?
00:26:46Upper right a bit?
00:26:48Below left.
00:26:55Okay? You've got the city there. Do you remember what goes above the city on this thing?
00:27:02The pressure?
00:27:04Then we do- write on the left.
00:27:09Pressure is on the left.
00:27:13When you do the pressure, make sure you show falling, steady or rising, either with the letters or the arrows.
00:27:18Rising would be just shooting straight across, a horizontal line.
00:27:26Okay. So, now, if you're not doing humidity, the only thing you have left is wind speed and direction. Do you remember how that was represented?
00:27:34Um, (by an arrow).
00:27:35By an arrow.
00:27:36An arrow that's shooting into the circle.
00:27:40And it is a //northeast wind, so-
00:27:40//North... in this area down here? That way?
00:27:43That's northwest.
00:27:44You're thinking of, like, Las Vegas and Nevada.
00:27:49If you have trouble remembering your directions, make little compass rows at the top of your map.
00:28:04Let's see if I find the state.
00:28:06(Do we do that) (inaudible)?
00:28:08No. You don't need to worry- all of these weather- or all of the wind directions are in either northeast or south- or south-
00:28:14I didn't put east, northeast or-
00:28:16No. I didn't do any of that.
00:28:18Where is Hatteras?
00:28:19Can I see the map when you're done, Hannah?
00:28:23What state is it in?
00:28:25You can tell her, Jennifer.
00:28:27I don't know.
00:28:28Oh, you guys, I told you where it was.
00:28:30I- I remember it.
00:28:31I found out, this-
00:28:33If you remember, then you can tell me.
00:28:36I remember her telling us. I just don't remember where.
00:28:38I remember her talking about it.
00:28:39This is a-
00:28:42Cape Hatteras-
00:28:44Yes. In your- on your map in your book it says Cape Hatteras, right.
00:28:49Okay. It's in the book.
00:28:49Oh, that helps.
00:28:50Oh, that hurt.
00:28:50It's not on your plastic map.
00:28:52Oh. It's not?
00:28:55Does that help?
00:28:57I don't think it is. It might be.
00:28:58It's North Carolina.
00:29:01Nope. It's not on your plastic map.
00:29:03It's out in the ocean.
00:29:05Well, no. The name is out in the ocean. The little dot //is actually on land.
00:29:07//There's no dot.
00:29:08There's no dot.
00:29:09It's just out in the middle of the ocean.
00:29:16You're right. There is no dot. Hmm. I'm looking in the wrong place anyways. //I'm looking in-
00:29:21//(Where's) New York in New York? It's not on this map. It must be on that-
00:29:23It's on the very corner, like, //if you (go) that way, let's say go to B, it's on the very bottom.
00:29:25//New York is on here. It's just very hard to find.
00:29:27All right. On this one?
00:29:28Mm-hm. Here's the state.
00:29:30Right. //Oh. There it is.
00:29:31Here's the city right there. Yeah.
00:29:32I'm stupid.
00:29:34You're not stupid. It's just buried on an island.
00:29:38You know, partly would be like-
00:29:39"Partly" is 50. Partly is 50. 50.
00:29:42Partly is 50. Partly is 50, Mitch.
00:29:46"Mostly" is 75 (inaudible) very cloudy.
00:29:48You haven't finished the Detroit station weather model yet.
00:29:52Shouldn't you finish that? Before you start one?
00:29:54I mean, that's what I would do. I guess you can do it any way you want, but- I guess everybody else is doing it that way, too.
00:30:04Remember to keep your handwriting very small and really nice and neat, those of you that struggle with neat. Really nice and neat.
00:30:15That good?
00:30:17SN :00]
00:30:19Miss A, there's a river through it, but there is no little dot for it.
00:30:26How about on the plastic map? That's why I gave you that plastic map, too, because-
00:30:30Plastic map.
00:30:32some of these cities- some of these cities are not as maj- well, Des Moines is a major city, but some aren't.
00:30:40Oh. It's right in the middle of it.
00:30:43And they're just on weather maps because they have a weather station there.
00:30:52Do we have to label like temperature, pressure?
00:30:55What did you have to do on the weather station model?
00:30:57I don't know. I-
00:30:59Oh. You mean tell me what it is? No. I know what it is.
00:31:01All right.
00:31:02Yeah. No. You just write it down.
00:31:05Okay, Jeff. Circle, and you put New York right there. Okay. And keep this- that right there.
00:31:15Can we just put like NC- I mean NY for like New York?
00:31:20Yeah. Make sure I'm not- make sure you don't get too much clutter around it so that you can't tell that that's what it is.
00:31:26Okay? So make it clear enough that I'll be able to see it, because NY could easily get lost in there.
00:31:35What do we put for "steady?"
00:31:39Or an arrow- here's your circle,
00:31:41An arrow just shooting off.
00:32:01Here you are, Mitch.
00:32:02You can use the eraser.
00:32:04Use yours. My pencil doesn't show up.
00:32:07I'll go sharpen it.
00:32:09No. We're supposed to pencil that.
00:32:14You guys seem to be having a lot less trouble than second hour did, or maybe I just explained it better this time. I don't know.
00:32:23Miss A?
00:32:25It's hard for me to write //this small.
00:32:26//Now what are we supposed to do?
00:32:27I know.
00:32:28It's hard for me to even write.
00:32:29I told you it would be a challenge for some of you. Yes. You have very large handwriting.
00:32:33I got very horrible handwriting.
00:32:35Oh, no. That looks good, though. That looks- that's pretty good for you. Yeah.
00:32:41'Cause I know you would want to fill the map up with- like Los Angeles would cover from L.A. all the way to Florida.
00:32:46I know. It probably would.
00:32:47Mm-hm. Oh. Kansas City is Kansas City, Missouri. Did I say that?
00:32:54Okay. Missouri.
00:32:56Okay. I've seen (it in there).
00:33:00Hmm? Which one?
00:33:03Like Kansas City. I didn't know if it- it's right there, isn't it?
00:33:07Yep. It's right on the edge. And then there's another one in Kansas, too, but it's not as big of a city. This is a big city here.
00:33:14You can't even see it.
00:33:15I know. They don't have it on that map. Do they have it on the plastic one?
00:33:23Missouri. Yep. And Missouri, yep. And Kansas.
00:33:30Miss A, what is it? North, south-
00:33:34East and west.
00:33:36E- does east go right there?
00:33:38I (don't) need painkillers.
00:33:40I can't give you medicine.
00:33:43She would have to bring either a written- she would have to bring a note. We need something written that says that we can-
00:33:51Do you want to go call home?
00:33:54Well, I don't want to go home.
00:33:57Well, if you don't want to go home, can you call home and somebody can bring you the medicine?
00:34:00I don't have medicine.
00:34:03Aspirin? Painkiller?
00:34:05Aspirin? Will it, like, let me be able to hear?
00:34:08Tylenol? It won't let you hear, but it'll kill the hurt- it'll kill the pain if you're in pain.
00:34:13I'm in a lot of pain.
00:34:14Well, then you need to take like Tylenol or something. Do you want to call home?
00:34:20Okay. Do you want to call from here or do you want to go down to the office?
00:34:21Doesn't matter.
00:34:22Is it like around here?
00:34:24It's over there. It's not long distance.
00:34:26Okay. Yeah. Go ahead and call home. See if somebody can bring you something. We're not allowed to administer any medication.
00:34:32Not even cough drops. Nine.
00:34:34Press nine?
00:34:37Brooke, where did you get "Des Moines"?
00:34:39//Des Moines.
00:34:40//Des Moines. Des Moines.
00:34:41The S is silent.
00:34:42It is in Iowa.
00:34:44In your book or the plastic map?
00:34:46Plastic map.
00:34:47Plastic map only.
00:34:50How far did you get?
00:34:51I don't know where humidity goes.
00:34:53Where what?
00:34:54Humidity goes.
00:34:55Humidity. Were you listening when I gave directions?
00:35:00You weren't listening? It's showing right now. What did I say about humidity? Did you have to put humidity on it last week?
00:35:09Think for a minute. Did you remember putting any on that worksheet we did?
00:35:17Isn't it-
00:35:19Yeah. It goes right below temperature, doesn't it?
00:35:22No? It goes-
00:35:23Does it go below air pressure?
00:35:25Dew point goes below air temperature. Humidity is not on your station model at all. Remember I said that?
00:35:32Yeah. I got dew point underneath.
00:35:35Ah. It's not on there at all.
00:35:37Oh. Just pressure- what?
00:35:39Humidity isn't on there at all.
00:35:42There's no humidity on that station model. Because when you look at dew point, you should be able to tell what the humidity is like, right?
00:35:50For instance, look at-
00:35:55is it New Orleans or Kansas City? Whose got a hundred percent humidity?
00:36:04Not only Denver.
00:36:05Okay. There's Denver. Okay. What's temperature in Denver?
00:36:10What's dew point?
00:36:12So what does that tell you about the humidity?
00:36:14It's gonna rain.
00:36:15What's the humidity?
00:36:20A hundred percent.
00:36:22It's gonna rain or snow.
00:36:23It's- and it is doing that, right? Right.
00:36:27Or it's gonna- I don't know.
00:36:36I will eliminate the ability to talk to your neighbors with- for the worksheet, if we're gonna talk about other things.
00:36:44Is your phone- it says- like I don't know if it //says "message for you."
00:36:47//Message for you. I know. Somebody called me last week and left me a message. I never answered it.
00:36:54Okay? Do you get it now, Stuart? No humidity because you can tell the humidity by the dew point. How are you doing?
00:37:02Now, these all have to go a certain way.
00:37:06This one I can't tell- oh. Okay. There it is. Your direction for wind.
00:37:20What are the cloudies again? I forgot.
00:37:23The cloudies?
00:37:24Yes. Now, I know this is clear.
00:37:28And I say-
00:37:30What one is this one?
00:37:31I say cloudy.
00:37:34Okay. But you've got some sun there. Is it completely cloudy?
00:37:39No. It's just cloudy. Mostly cloudy is completely cloudy, right? The same thing?
00:37:46Mostly cloudy means there must be some- a little bit of sun.
00:37:50All right.
00:37:51So what have you got there?
00:37:52Mostly cloudy.
00:37:53A little bit of sun. Right. You want it all the way cloudy so what are you going to do?
00:37:56Fill it in?
00:37:59All right. So whole circle, that's cloudy.
00:38:05And then half is partly cloudy, right?
00:38:14And then... cloudy, partly cloudy, and then mostly cloudy is 75%.
00:38:29That's right. You know what it is. You're the only one that has to look at it. So then what is going to be mostly sunny?
00:38:42A quarter.
00:38:43That's clear. That's completely sunny.
00:38:47Completely sunny?
00:38:48If you've got partly cloudy here, what's mostly sunny gonna look like?
00:38:54Mostly clear except a little bit of clouds. Right. Right, right, right. Yep. Yep. There you go. You got it.
00:39:05You sigh like you're in pain, Todd. Is this hurting?
00:39:14Come on, you're not gonna make me stand here the whole time, are you?
00:39:18Okay. Then stay on task, okay?
00:39:19Where is Kansas City at?
00:39:21I'm trying to calm her down.
00:39:23I've got energy because he won't let me talk all day.
00:39:25Okay. A very good question, Jennifer. That was the other one I hadn't answered. Listen, please.
00:39:30One of those has a variable direction which means you're not gonna have an arrow shooting into that circle because they're all over the place.
00:39:38If you don't have the arrow shooting into the circle, then you can't put the what? Five miles per hour?
00:39:43Okay. So put the line on there anywhere. Because if it's variable, it's changing a whole lot.
00:39:48So just put it anywhere, and then put the five-mile-an-hour line on there. There's another one, though, that says variable-
00:39:57speed, so put the arrow for the wind direction and then put a V at the end of it, okay?
00:40:04Because you can't say. It's probably anywhere from three to 15 miles an hour.
00:40:10Okay? Get it?
00:40:13Okay. Does that help? Okay.
00:40:24Okay, with that line stuff with the- with the-
00:40:31The calm wind chill?
00:40:32Yeah. The wind speed.
00:40:34The lines with the five and the 10. How are we supposed to know-
00:40:38Nine is closer to what? Nine or- I mean 10 or five?
00:40:42It would be ten.
00:40:43Okay. So use the 10.
00:40:46Okay? And even when you get to the 12- that's halfway between the 10 and the 15- you'll pick.
00:40:54Okay? You can either pick one 10 mile an hour or the 10 mile and five mile.
00:40:58What about the "calm?" What do you do? Do you just-
00:41:00"Calm" you don't put any //line at all.
00:41:02There's no line because there's no direction, there's no nothing, okay?
00:41:05Oh. Uh, and another thing. What if you have like three? Do you put like different-
00:41:11You shouldn't have two on there. It's one or the other. What is that? New York?
00:41:15Yes, New York.
00:41:16Nine-mile-an-hour wind out of the northeast. Which direction is the northeast?
00:41:22Up here.
00:41:23Yeah. So erase that one you've got on the bottom, and then don't forget to put your 10-mile-an-hour line on there.
00:41:38All right. How many of you guys got done here? We only have like 15 minutes. How many have you got gone?
00:41:47I'm on my first one.
00:41:48On your what?
00:41:49My first one.
00:41:50Hannah! Oh. You found all your cities first?
00:41:56I'm like halfway done.
00:42:00You're halfway done?
00:42:02What would- mostly cloudy is that, right?
00:42:05And partly- partly cloudy is half?
00:42:10And then "mostly" is just like 75%?
00:42:13//What would the 25% be?
00:42:14What do you think? What is it mostly of if only a quarter of it is dark?
00:42:18Mostly clear.
00:42:19Mostly clear or mostly sunny.
00:42:21It goes like that.
00:42:22You don't have any on there.
00:42:24Unfortunately it was a cloudy day all the way around the country.
00:42:28Like light green air is light rain?
00:42:33Yeah. If you use the- when you use the colored pencils, if they're dull, just use the hand sharpeners please. Don't use the power sharpeners,
00:42:42because they chew it up, eat them away.
00:42:44That's just (inaudible).
00:42:48Yeah they drew their hand today, in art. They didn't-
00:42:54We had to draw it upside down.
00:42:55You had to do your hand. Remember you had to do your hand?
00:42:59Yeah, but we had to draw upside down.
00:43:00They haven't got there yet.
00:43:03Can I go back there?
00:43:04Don't push too hard.
00:43:05Oh, man, it hurts.
00:43:06What are you in now?
00:43:08I'm in... a reading thing.
00:43:12Oh, (inaudible). No, you can't come back to art. Sorry.
00:43:24It's creepy.
00:43:24What's creepy?
00:43:26My cousin-
00:43:30Her cousin has a crush on him.
00:43:31No. She used to.
00:43:33Whose cousin?
00:43:34My cousin used to.
00:43:35Your cousin has a- had a //crush on you?
00:43:36//She used to. Yeah, that's why she creeps me out.
00:43:40Oh. Not Lydia, your cousin?
00:43:44I'm afraid of her.
00:43:46She's strong.
00:43:47She really scares me.
00:43:48I don't like my cousin; I like my cousin's friends.
00:43:53My cousin scares me. I don't like him. I like my cousin's friends.
00:43:57I don't know.
00:43:59Make sure you're putting those in the right place.
00:44:01I am.
00:44:01Okay. Because it looks like Los Angeles is on top of your circle. Your circle needs to be to the left of that city name.
00:44:15Five miles an hour variable directions. //Does that need to be in any direction?
00:44:16//What one are we on, Los Angeles?
00:44:18Yes. And that's the one where I told you to just put the arrow anywhere.
00:44:25I can't find it, Mitch.
00:44:27How do you do a variable wind?
00:44:32Okay. My parents were in Las Vegas, you know, September 11.
00:44:34It's there.
00:44:35They were?
00:44:37Yeah. You see, they made a really wise decision. You see, originally my dad didn't want to.
00:44:42This is B.
00:44:45It's what she said.
00:44:49And then you put a V on it.
00:44:54That's for the five miles per hour, I think.
00:44:57They did drive? I wouldn't have gotten on an airplane.
00:44:59They had to drive- they couldn't get- like-
00:45:01Oh. //Yeah.
00:45:02//It was either drive or spend 200 dollars a night //to stay at the hotel.
00:45:04//I'm sorry, Jeff.
00:45:06Were they even flying planes at that point?
00:45:08When they were coming //back they were?
00:45:08//Oh. No. No, they weren't.
00:45:10We weren't having any planes in the air at that point. Wow.
00:45:13So they had to drive back and-
00:45:15It would be a nice drive, unless you're in a hurry.
00:45:17They- they tried to do that. See, they put-
00:45:21What's today? The 28th?
00:45:22But, I mean, they didn't have that thing- I mean they weren't back- they //initially were supposed to be gone one week.
00:45:27But they weren't back home (inaudible).
00:45:29Oh. Yeah.
00:45:31(inaudible) if they didn't have that car.
00:45:33Because there was so many people //who were just diving to get in a car.
00:45:33//Your name's right there.
00:45:35Oh, I'm sure. Yeah. Supply and demand.
00:45:38They just, like-
00:45:40I drew variable direction. Like, what do you put for variable direction?
00:45:43Variable direction? I think I answered that a few minutes ago.
00:45:46I thought you answered variable speed.
00:45:47What did I say about variable direction, Wes?
00:45:51What did I say when the direction is variable?
00:45:52It can go any- you can just point the arrow in whatever way you want it to.
00:45:56Just put a line on there somewhere to attach your five miles per hour.
00:46:04There you go. There you go.
00:46:11Do we have to use different colors?
00:46:13No. Uh-uh. No. Not on the station model. The whole thing can be the same color. When you shade, if you want to use color, you can use color.
00:46:21Okay. It's just like shading when you did the station model worksheet.
00:46:25How are you doing over here?
00:46:27You get it?
00:46:31How many you got done, Mitch?
00:46:31This thing is too big, but-
00:46:33How many station models?
00:46:34One, two, three, //four, five, six, seven.
00:46:39Eight? One, two, three, four, five, six, seven, eight. Okay.
00:46:44Yes? Who's calling me? What?
00:46:46Since Cape Hatteras is out in the ocean, where are we supposed to put it?
00:46:49It isn't in the ocean.
00:46:50There's no dot.
00:46:51It is right- it's a cape so I'm assuming it's like right here. We'll just make it right there. There's the city. Now go with it.
00:47:02It's not in the ocean.
00:47:04That's how they showed it on the map.
00:47:06Actually, I should show you the picture of the lighthouse that's there.
00:47:10I'll pull that stuff out for tomorrow because it's kind of interesting.
00:47:24Where is Cape Hatteras?
00:47:26It's out in the ocean.
00:47:30SN :00]
00:47:31SN :00]
00:47:32It's the little dot. It's right there.
00:47:34It's not in your book map. Oh. Yes, it is in your book map. It's not on the plastic map. It's right here.
00:47:39I know.
00:47:40I know, but it's-
00:47:41You know? Why are you asking //me?
00:47:42//Well, it's like "where do I put it?"
00:47:44I know because I had to go there.
00:47:45It- it should be like right here somewhere. Anywhere that it looks like it might- right in that little cove area there.
00:47:54There it is.
00:47:55There- okay. I'll- to put it to you this way, there's a lighthouse on Cape Hatteras so it can't be back in that cove area, right?
00:48:03It's got to be the most sticking out point of North Carolina. How's that?
00:48:09That's good.
00:48:09Okay. But they had to move the lighthouse because the most sticking out point of North Carolina got washed away, and they thought //that they-
00:48:20SN :00]
00:48:22So wait, a continent got washed out to sea?
00:48:25Okay, Dorothy. You got me there.
00:48:27I'm confused.
00:48:28I can't- no. They actually rolled it back. It's very interesting.
00:48:31//I'll find the stuff. You keep working, I'll find the picture.
00:48:34That confuses me.
00:48:34You just keep working. Just-
00:48:35It's right here. That little part-
00:48:37It's that little part sticking out right there.
00:48:41Yeah, everything filled in. You're gonna have to wait for your group mates to figure out their stuff so //that you can move on to it, but-
00:48:46//So Rhode Island is floating up the sea?
00:48:49No. Rhode Island //is not an island-
00:48:50//Look at- look at where your cloudiness is; look at where your precipitation is and you can go ahead and shade that,
00:48:58and then they're all gonna want to look at yours when they get done so they can copy it.
00:49:02Rhode Island is not an island.
00:49:04Rhode Island is not an island, nope. They probably thought it was when they named it.
00:49:19Where is it anyways?
00:49:21Where is Rhode Island?
00:49:23There is Iowa.
00:49:29Rhode Island is-
00:49:35(If you see) Massachusetts (you see towards) Rhode Island-
00:49:37I'm really thinking we need an American geography class, you guys.
00:49:41Oh, yeah.
00:49:47Oh, yeah. I see it now.
00:49:48When did you say it's Rhode Island?
00:49:50Let's (inaudible) Massachusetts.
00:49:52Isn't that the tiniest state?
00:50:03SN :00]
00:50:16Uh, is there a problem? Do I need to be babysitting?
00:50:20Yeah. You need to baby-sit them.
00:50:24Baby-sit them.
00:50:22No, I don't think that's in my job description.
00:50:26Baby-sit (inaudible).
00:50:29Not when the kid being babysitted is 14 years old.
00:50:36That means it's not me because I'm not 14 years old.
00:50:39Neither am I.
00:50:41You baby-sit at 14?
00:50:46There it is.
00:50:47Miss Anderson?
00:50:51Is the higher the humidity where a high pressure is or low pressure?
00:50:54Hmm. Good question. Where would the most humidity be?
00:50:59Think about- look at- well, think about a weather map.
00:51:07Where is the precipitation around the fronts?
00:51:15Precipitation is behind the front or in front of the front?
00:51:17It's in front of it.
00:51:19In front of the front. Okay. So if you're looking at precipitation, you're looking at humidity, too.
00:51:25So what is higher humidity gonna tell you?
00:51:34It's gonna tell you there's precipitation so where would it be located in relationship to the front?
00:51:38By the precipitation.
00:51:40What will be by the precipitation?
00:51:42The front.
00:51:44The front. What front?
00:51:47Cold front.
00:51:49Very good.
00:51:51Where is Des Moines?
00:51:52It's not Des Moines. It is Des Moines.
00:51:56Where is it?
00:51:56It's in Iowa.
00:52:01I read that book in art.
00:52:03I was looking through that book in art.
00:52:04Were you?
00:52:05One of the last days.
00:52:06Is the bell going to ring late today?
00:52:08You know what? I'm not sure. Jennifer, go ask Mrs. O'Brian if she is going to let everybody out for lunch by the bell or at nine minutes after.
00:52:21Okay? Okay. So far Jennifer is the only one that got all of the cities plotted.
00:52:27I'm almost done.
00:52:27I'm almost done.
00:52:28Two more.
00:52:29Two more? You might finish if you don't talk.
00:52:33This is a-
00:52:34I haven't been talking all day.
00:52:36Yes you have.
00:52:36I get a lot of //energy when I-
00:52:38//(inaudible) I hate it.
00:52:39//Sit on your butt.
00:52:40I don't like this. I get a lot of energy when I don't talk.
00:52:43You what?
00:52:43I don't like this. I get a lot of energy when I don't talk.
00:52:45Tomorrow is gonna be even worse because you won't be allowed to talk in here either.
00:52:49I'll be running around the whole- the whole lunch hour.
00:52:52Mark, sit. Thank you. Work.
00:52:55We need the map.
00:53:01I got all the cities.
00:53:02You got all the cities done? Okay. I told Jennifer to go ahead and- ooh, Cynthia, you went ahead of your group.
00:53:07You're supposed to be making those decisions with your group together.
00:53:10Yeah but she- she wouldn't-
00:53:11Okay. When you get to the point when you are ready to do precipitation and the fronts, decide as a group,
00:53:19so that you can explain why you think the front needs to go somewhere and then someone else can either debate with you or agree with you.
00:53:27And don't agree with the person just because they get better grades in science.
00:53:33Because a lot of times when it comes to this kind of stuff they won't get it. It happens an awful lot.
00:53:39They know the bookwork, they understand some of the concepts, but when it comes to actually applying them,
00:53:45sometimes those people that really get good grades have a real hard time with this kind of stuff. Mitch?
00:53:50Is this homework?
00:53:51No. It is not homework.
00:53:53Oh, good.
00:53:54I'm gonna give you one more minute to work and then I'm gonna explain the rest to you. What did she say?
00:53:59Nine after.
00:53:59Nine after? I figured she was gonna be going to lunch.
00:54:02So can we get out at the bell?
00:54:04No. You'll get out before the bell. If you want to get out at the bell, it probably won't ring until a quarter after or so.
00:54:11Oh. The bells are behind?
00:54:12The bells are behind. Because it would actually be ringing during the middle of- if we were following that clock during the middle of fourth hour.
00:54:20It's that middle bell.
00:54:23I don't like the fourth- the bell for fourth hour because there's no minute bell which is why I'm always late.
00:54:28You won't be today.
00:54:28I know.
00:54:29Because there will be teachers in the hallway making sure you make it, because you won't be talking to each other in the hallway.
00:54:34It's actually working out quite nicely.
00:54:36I feel like I'm in a state prison. I mean, //don't they-
00:54:38//That's how we want it to feel.
00:54:39About the only difference is that- is that the teachers aren't carrying 12 gauges.
00:54:43No, we won't do that, but we are definitely- it is definitely a //crackdown situation.
00:54:49//You just keep hurting yourself.
00:54:50Yes, I do, and it's not fair.
00:54:53I keep //(inaudible)-
00:54:56I have a question.
00:54:59How did this ever start anyways?
00:55:00How did that start anyways?
00:55:00Last Friday's behavior.
00:55:07Houston's in Texas.
00:55:08Who's done?
00:55:10Oh, there's that lunch bell. Stop. Freeze. You are responsible to bring the map and the instructions back to this room-
00:55:19Can you send Dorothy to the office?
00:55:21She is on her way.
00:55:22Tomorrow if you don't have it, am I going to give you another one?
00:55:26No. Are you going to get a grade?
00:55:28No. Just so long as we understand that. Have a nice lunch.
00:55:33You, too, Mrs. Anderson.
00:55:34Make sure everything else is on the middle of the table. Don't- thank you, Jeff.
00:55:38Do you want your pencil back?
00:55:39Yes, I want my pencil back. Put that on and leave it on. It's not working, Victoria.
00:55:48See you tomorrow, Mrs. Anderson.
00:55:48Oh, thank you, Jeff. I'll see you tomorrow, too. Have a good afternoon.
