00:00:00,000 --> 00:00:07,000
Hi, we're students from a region school right here in Andernes, Norway.

2
00:00:07,000 --> 00:00:11,000
NASA Connect asked us to show you this activity. It's called Red Sea and Aurora.

3
00:00:11,000 --> 00:00:15,000
You can download the lesson guide and a list of materials from the NASA Connect website.

4
00:00:15,000 --> 00:00:18,000
Here are the main objectives.

5
00:00:18,000 --> 00:00:24,000
Students will find and plot locations on maps using geographic coordinates,

6
00:00:24,000 --> 00:00:28,000
draw conclusions based on graphical information,

7
00:00:28,000 --> 00:00:31,000
and convert centimeters to kilometers using a given scale.

8
00:00:31,000 --> 00:00:34,000
Here are some terms you will need to know.

9
00:00:34,000 --> 00:00:38,000
Latitude, a geographic coordinate measured from the equator,

10
00:00:38,000 --> 00:00:42,000
with positive values going north and negative values going south.

11
00:00:42,000 --> 00:00:46,000
Longitude, a geographic coordinate measured from the prime meridians,

12
00:00:46,000 --> 00:00:48,000
which is a longitude that runs from Greenwich, England,

13
00:00:48,000 --> 00:00:52,000
with positive values going east and negative values going west.

14
00:00:52,000 --> 00:00:55,000
Good morning, class.

15
00:00:55,000 --> 00:01:01,000
Northern lights are seen most dramatically in only certain places in the northern hemisphere.

16
00:01:01,000 --> 00:01:08,000
Today, you will plot the location and boundaries of a typical auroral oval in the Arctic region.

17
00:01:08,000 --> 00:01:14,000
You will see its geographic extent and determine its relationship to familiar continents and countries.

18
00:01:14,000 --> 00:01:17,000
Distribute all student materials.

19
00:01:17,000 --> 00:01:19,000
Students can work alone or in pairs.

20
00:01:19,000 --> 00:01:24,000
Students, label the latitude lines beginning at the center point with 90 degrees.

21
00:01:24,000 --> 00:01:29,000
Then mark each circle 10 degrees less than the previous circle, ending at 20 degrees.

22
00:01:29,000 --> 00:01:32,000
Next, label the unmarked longitude lines.

23
00:01:32,000 --> 00:01:35,000
Plot the points onto the geographic grid for the outer ring.

24
00:01:35,000 --> 00:01:39,000
The geographic data points can be found on the student activity sheet.

25
00:01:39,000 --> 00:01:43,000
The points are identified as ordered pairs, longitude, latitude.

26
00:01:43,000 --> 00:01:51,000
For example, the ordered pair 180, 60 means 180 degrees longitude and 60 degrees latitude.

27
00:01:51,000 --> 00:01:53,000
Connect the points in the outer ring.

28
00:01:53,000 --> 00:01:58,000
Now, plot the points onto the geographic grid for the inner ring and connect the points.

29
00:01:58,000 --> 00:02:02,000
Using the scale 1 centimeter equals 1400 kilometers,

30
00:02:02,000 --> 00:02:07,000
measure, in kilometers, the approximate width of the shortest and longest distances

31
00:02:07,000 --> 00:02:11,000
between the inner and outer rings and determine the range.

32
00:02:11,000 --> 00:02:14,000
Record these values on the student activity sheet.

33
00:02:14,000 --> 00:02:15,000
Okay, class.

34
00:02:15,000 --> 00:02:23,000
From the analysis of your graph, how far is the center of the auroral oval from the North Pole?

35
00:02:23,000 --> 00:02:29,000
I calculated that the center of the auroral oval is about 500 kilometers from the North Pole.

36
00:02:29,000 --> 00:02:31,000
Very good, Marita.

37
00:02:31,000 --> 00:02:35,000
And where would you travel in North America to see the Northern Lights?

38
00:02:35,000 --> 00:02:40,000
From the graph, either Canada or Alaska are the best places to view the Northern Lights.

39
00:02:41,000 --> 00:02:44,000
Students, once you complete the hands-on activity,

40
00:02:44,000 --> 00:02:49,000
check out the web activity for today's program called the NASA Northern Lights Challenge.

41
00:02:49,000 --> 00:02:52,000
It can be accessed at the NASA Connect website.

42
00:02:52,000 --> 00:02:55,000
This activity is created to be fun, interactive,

43
00:02:55,000 --> 00:02:58,000
and will challenge your ability to solve problems.

44
00:02:58,000 --> 00:02:59,000
During the course of the activity,

45
00:02:59,000 --> 00:03:04,000
you'll use various probes to explore properties of the planets in our solar system.

46
00:03:04,000 --> 00:03:08,000
There are eight interactive probes in different colored boxes along the two sides.

47
00:03:08,000 --> 00:03:10,000
You'll learn about the temperature,

48
00:03:10,000 --> 00:03:12,000
magnetic field strength,

49
00:03:12,000 --> 00:03:13,000
solar wind density,

50
00:03:13,000 --> 00:03:15,000
atmospheric gases,

51
00:03:15,000 --> 00:03:16,000
mean distance,

52
00:03:16,000 --> 00:03:17,000
mean density,

53
00:03:17,000 --> 00:03:18,000
gravity,

54
00:03:18,000 --> 00:03:20,000
and speed on other planets.

55
00:03:20,000 --> 00:03:22,000
Upon exploring each planet,

56
00:03:22,000 --> 00:03:25,000
you will apply what you learn to solve the following problem.

57
00:03:25,000 --> 00:03:27,000
What other planets may have the Northern Lights?

58
00:03:27,000 --> 00:03:30,000
Special thanks to the students from Brandon Middle School

59
00:03:30,000 --> 00:03:33,000
and Lansdowne Middle School in Virginia Beach, Virginia,

60
00:03:33,000 --> 00:03:35,000
for demonstrating this web activity.
