1 00:00:00,000 --> 00:00:07,580 My thanks to all the hurricane hunters, you know earlier you used computer simulation to help you predict and analyze hurricane tracks 2 00:00:07,980 --> 00:00:15,080 Now, how would you like to calculate where a hurricane will make a landfall and then issue watches and warnings for people on the coast? 3 00:00:15,480 --> 00:00:20,260 NASA Connect traveled north to Boston, Massachusetts for today's classroom activity 4 00:00:20,260 --> 00:00:26,260 Hi, it's Victor from the Edith Eppin Elementary School in Boston, Massachusetts 5 00:00:26,260 --> 00:00:32,260 NASA Connect asked us to show you the classroom activity for today's show. It's a game called the Imperfect Storm 6 00:00:32,260 --> 00:00:38,260 Teachers, make sure you download the lesson guide for this activity from the NASA Connect website 7 00:00:38,260 --> 00:00:42,260 In it, you'll find materials, directions, and student worksheets 8 00:00:42,260 --> 00:00:46,260 To begin, your teacher will divide you into teams of meteorologists 9 00:00:46,260 --> 00:00:50,260 It is your job to track the storm brewing off the coast of Africa 10 00:00:50,260 --> 00:00:55,260 Predict the probability of landfall and issue hurricane watches and warnings 11 00:00:55,260 --> 00:01:01,260 A hurricane watch means that hurricane conditions are possible within the next 36 hours 12 00:01:01,260 --> 00:01:07,260 A hurricane warning means that hurricane conditions are expected within the next 24 hours 13 00:01:07,260 --> 00:01:11,260 The team with the most accurate predictions will be the winners of the game 14 00:01:12,260 --> 00:01:17,260 First, construct your game board following the directions on your student direction sheet 15 00:01:17,260 --> 00:01:22,260 The Saffir-Simpson scale tells you the classification of a storm by its wind speed 16 00:01:22,260 --> 00:01:28,260 In this game, disks represent tropical storms and hurricanes, categories 1 through 5 17 00:01:28,260 --> 00:01:33,260 Right off the coast of Africa, there is a tropical wave that is forming a low-pressure system 18 00:01:33,260 --> 00:01:42,260 Winds are 30 miles per hour, the coordinates are 16 degrees north and 35 degrees west as of 06 Zulu time 19 00:01:42,260 --> 00:01:48,260 Record this information on your data sheet and use the Saffir-Simpson scale to classify the storm 20 00:01:48,260 --> 00:01:53,260 Plot the coordinate or position of the storm on your game board with the appropriate color from the key 21 00:01:53,260 --> 00:01:56,260 Your teacher will give you the next two data points 22 00:01:56,260 --> 00:02:00,260 As before, record, classify, and plot the storm's position 23 00:02:00,260 --> 00:02:03,260 Now, let's determine the speed the storm traveled 24 00:02:03,260 --> 00:02:08,260 If you know distance and time, you can calculate speed 25 00:02:08,260 --> 00:02:13,260 Use a compass and the Mallet scale on your game board to determine the distance the storm traveled 26 00:02:13,260 --> 00:02:17,260 Then use Formula 1 to calculate the speed the storm traveled 27 00:02:17,260 --> 00:02:23,260 Before issuing watches and warnings, you must calculate the distance the storm will travel 28 00:02:23,260 --> 00:02:29,260 Use Formula 2 on your game board to calculate the distance the storm will travel in 36 hours 29 00:02:29,260 --> 00:02:35,260 Then place the appropriate storm disc over the third point on your game board and secure it like this 30 00:02:35,260 --> 00:02:41,260 Use a compass, your calculations, and the Mallet scale to draw an arc from the outer edge of the disc 31 00:02:41,260 --> 00:02:47,260 The area between the disc and the arc will receive tropical storm force winds in 36 hours 32 00:02:47,260 --> 00:02:50,260 An atlas will help you identify land areas at risk 33 00:02:50,260 --> 00:02:52,260 Record your estimated watch 34 00:02:52,260 --> 00:02:57,260 Now use Formula 3 to calculate the distance in 24 hours and issue a warning 35 00:02:57,260 --> 00:02:59,260 Teams, we have a conflict 36 00:02:59,260 --> 00:03:04,260 A cruise ship is steaming ahead at 15 miles per hour from the Bahamas towards Miami 37 00:03:04,260 --> 00:03:13,260 It's your job as meteorologists to find the location of the ship, decide what action, if any, should be taken, and record your decision 38 00:03:13,260 --> 00:03:19,260 Your teacher will review your data sheet and award points for accurate calculations and predictions 39 00:03:19,260 --> 00:03:25,260 The game continues as you receive more coordinates, weather data, and conflicts from your teacher 40 00:03:25,260 --> 00:03:29,260 When the winds increase to hurricane force, you will need to use two discs instead of one 41 00:03:29,260 --> 00:03:34,260 This is because the tropical storm force winds extend farther out than the hurricane force winds 42 00:03:34,260 --> 00:03:38,260 From this point on, you will only issue hurricane watches and warnings 43 00:03:38,260 --> 00:03:44,260 So make sure you place your compass point on the outer edge of the hurricane disc, not the tropical storm disc 44 00:03:44,260 --> 00:03:48,260 When the hurricane changes categories, you will need to change discs 45 00:03:48,260 --> 00:03:54,260 As the hurricane approaches land, use your expertise to predict where it will make landfall 46 00:03:54,260 --> 00:03:59,260 Points are awarded to the team with the most accurate predictions and solutions to the conflicts 47 00:03:59,260 --> 00:04:03,260 So plot, measure, calculate, and use your atlas carefully 48 00:04:03,260 --> 00:04:07,260 The team with the most points at the end wins the game! 49 00:04:07,260 --> 00:04:12,260 Special thanks to AIWA Chapter at Boston University for their help with this activity
