Thanks, Dr. Shepard. 00:00:00

Hey guys, check out this really cool web activity 00:00:04

that should motivate you to learn more 00:00:07

about the 12 national applications. 00:00:09

Thank you, sir. 00:00:12

Going fishing! 00:00:14

Hey, let's take a look at two really cool web activities 00:00:16

developed by space stars 00:00:19

to learn more about two of the Earth's subsystems, 00:00:21

the lithosphere and the hydrosphere. 00:00:24

The two web activities are called 00:00:27

Earthquake Hunters and Water World, 00:00:29

and both activities can be downloaded 00:00:31

from the NASA Connect website. 00:00:33

Do you have what it takes to be an earthquake hunter? 00:00:35

NASA has a very important satellite system 00:00:38

called the Global Earthquake Satellite System, 00:00:41

or GESS, 00:00:44

that is very concerned with tectonic activity 00:00:46

on the Earth's surface. 00:00:49

Say, do you know what tectonic means? 00:00:51

Well, it pertains to the structure 00:00:54

or movement of the Earth's crust. 00:00:56

Now, this activity lets you step into the shoes 00:00:59

of the scientists studying information from GESS 00:01:02

by taking a look at the tectonic activity on Earth. 00:01:06

You will use a Geographic Information Systems, 00:01:09

or GIS, software tool 00:01:12

to allow you to analyze different types of data, 00:01:14

explore and investigate 00:01:17

where the majority of earthquakes took place 00:01:19

between 2002 and 2003. 00:01:22

Were they around large cities, such as Los Angeles, 00:01:25

Tokyo, Japan, or Mexico City, Mexico? 00:01:28

Do they occur all over the world, 00:01:32

or in just certain locations? 00:01:34

Is there a relationship between earthquakes 00:01:36

and plate boundaries? 00:01:38

It is your job to determine 00:01:40

where the majority of earthquakes occur around the world 00:01:42

and how many people they affect. 00:01:45

Can you forecast where the next earthquakes will occur? 00:01:47

In the second web activity called Water World, 00:01:50

students will explore the continent of Antarctica. 00:01:53

Approximately 90% of the world's snow and ice 00:01:56

can be found in Antarctica, 00:01:59

but there is more to this mysterious continent than just that. 00:02:01

What if all the frozen snow and ice on Antarctica melted? 00:02:05

Imagine what would happen if 30 million cubic kilometers 00:02:09

of snow and ice became part of the hydrosphere. 00:02:12

Students, you will analyze the map of the world 00:02:15

when the oceans are 5 meters, 50 meters, 00:02:18

and 73 meters above normal sea level. 00:02:21

What area of the world will be affected 00:02:24

by a 5-meter increase in sea level? 00:02:26

What about a 50-meter increase, 00:02:28

or a total thaw of Antarctica? 00:02:30

Will the place where you live still be above sea level? 00:02:33

The answers to all these questions are left for you to decide. 00:02:37

Okay, guys, now we can finally get to that question 00:02:42

that hasn't been answered. 00:02:45

How is the Earth system part of larger systems? 00:02:48

The answer to that question is left up to you. 00:02:51

Your challenge is to answer the question 00:02:54

based on what you learned from this program. 00:02:56

Develop a PowerPoint presentation, 00:02:59

write a report, or even design a piece of artwork. 00:03:01

Students, check out the Earth System Science Song on our website, 00:03:05

developed by Magic State of the Arts 00:03:09

and heard at the end of this program. 00:03:11

It might guide you in finding the answer to your question. 00:03:13

Submit your presentation, report, or artwork 00:03:17

to the NASA Connect website. 00:03:20

There's a good chance that your presentation 00:03:22

will be seen by millions of students across the country. 00:03:24

We look forward to your submittals. 00:03:27

Well, guys, that wraps up another episode of NASA Connect. 00:03:29

We'd like to thank everyone who helped make this program possible. 00:03:32

Got a comment, question, or suggestion? 00:03:35

Then email them to connect at lark.nasa.gov. 00:03:38

Or pick up a pen and mail them to NASA Connect, 00:03:43
