1 00:00:00,000 --> 00:00:04,000 Thanks, Dr. Shepard. 2 00:00:04,000 --> 00:00:07,000 Hey guys, check out this really cool web activity 3 00:00:07,000 --> 00:00:09,000 that should motivate you to learn more 4 00:00:09,000 --> 00:00:12,000 about the 12 national applications. 5 00:00:12,000 --> 00:00:14,000 Thank you, sir. 6 00:00:14,000 --> 00:00:16,000 Going fishing! 7 00:00:16,000 --> 00:00:19,000 Hey, let's take a look at two really cool web activities 8 00:00:19,000 --> 00:00:21,000 developed by space stars 9 00:00:21,000 --> 00:00:24,000 to learn more about two of the Earth's subsystems, 10 00:00:24,000 --> 00:00:27,000 the lithosphere and the hydrosphere. 11 00:00:27,000 --> 00:00:29,000 The two web activities are called 12 00:00:29,000 --> 00:00:31,000 Earthquake Hunters and Water World, 13 00:00:31,000 --> 00:00:33,000 and both activities can be downloaded 14 00:00:33,000 --> 00:00:35,000 from the NASA Connect website. 15 00:00:35,000 --> 00:00:38,000 Do you have what it takes to be an earthquake hunter? 16 00:00:38,000 --> 00:00:41,000 NASA has a very important satellite system 17 00:00:41,000 --> 00:00:44,000 called the Global Earthquake Satellite System, 18 00:00:44,000 --> 00:00:46,000 or GESS, 19 00:00:46,000 --> 00:00:49,000 that is very concerned with tectonic activity 20 00:00:49,000 --> 00:00:51,000 on the Earth's surface. 21 00:00:51,000 --> 00:00:54,000 Say, do you know what tectonic means? 22 00:00:54,000 --> 00:00:56,000 Well, it pertains to the structure 23 00:00:56,000 --> 00:00:59,000 or movement of the Earth's crust. 24 00:00:59,000 --> 00:01:02,000 Now, this activity lets you step into the shoes 25 00:01:02,000 --> 00:01:06,000 of the scientists studying information from GESS 26 00:01:06,000 --> 00:01:09,000 by taking a look at the tectonic activity on Earth. 27 00:01:09,000 --> 00:01:12,000 You will use a Geographic Information Systems, 28 00:01:12,000 --> 00:01:14,000 or GIS, software tool 29 00:01:14,000 --> 00:01:17,000 to allow you to analyze different types of data, 30 00:01:17,000 --> 00:01:19,000 explore and investigate 31 00:01:19,000 --> 00:01:22,000 where the majority of earthquakes took place 32 00:01:22,000 --> 00:01:25,000 between 2002 and 2003. 33 00:01:25,000 --> 00:01:28,000 Were they around large cities, such as Los Angeles, 34 00:01:28,000 --> 00:01:32,000 Tokyo, Japan, or Mexico City, Mexico? 35 00:01:32,000 --> 00:01:34,000 Do they occur all over the world, 36 00:01:34,000 --> 00:01:36,000 or in just certain locations? 37 00:01:36,000 --> 00:01:38,000 Is there a relationship between earthquakes 38 00:01:38,000 --> 00:01:40,000 and plate boundaries? 39 00:01:40,000 --> 00:01:42,000 It is your job to determine 40 00:01:42,000 --> 00:01:45,000 where the majority of earthquakes occur around the world 41 00:01:45,000 --> 00:01:47,000 and how many people they affect. 42 00:01:47,000 --> 00:01:50,000 Can you forecast where the next earthquakes will occur? 43 00:01:50,000 --> 00:01:53,000 In the second web activity called Water World, 44 00:01:53,000 --> 00:01:56,000 students will explore the continent of Antarctica. 45 00:01:56,000 --> 00:01:59,000 Approximately 90% of the world's snow and ice 46 00:01:59,000 --> 00:02:01,000 can be found in Antarctica, 47 00:02:01,000 --> 00:02:05,000 but there is more to this mysterious continent than just that. 48 00:02:05,000 --> 00:02:09,000 What if all the frozen snow and ice on Antarctica melted? 49 00:02:09,000 --> 00:02:12,000 Imagine what would happen if 30 million cubic kilometers 50 00:02:12,000 --> 00:02:15,000 of snow and ice became part of the hydrosphere. 51 00:02:15,000 --> 00:02:18,000 Students, you will analyze the map of the world 52 00:02:18,000 --> 00:02:21,000 when the oceans are 5 meters, 50 meters, 53 00:02:21,000 --> 00:02:24,000 and 73 meters above normal sea level. 54 00:02:24,000 --> 00:02:26,000 What area of the world will be affected 55 00:02:26,000 --> 00:02:28,000 by a 5-meter increase in sea level? 56 00:02:28,000 --> 00:02:30,000 What about a 50-meter increase, 57 00:02:30,000 --> 00:02:33,000 or a total thaw of Antarctica? 58 00:02:33,000 --> 00:02:37,000 Will the place where you live still be above sea level? 59 00:02:37,000 --> 00:02:42,000 The answers to all these questions are left for you to decide. 60 00:02:42,000 --> 00:02:45,000 Okay, guys, now we can finally get to that question 61 00:02:45,000 --> 00:02:47,000 that hasn't been answered. 62 00:02:48,000 --> 00:02:51,000 How is the Earth system part of larger systems? 63 00:02:51,000 --> 00:02:54,000 The answer to that question is left up to you. 64 00:02:54,000 --> 00:02:56,000 Your challenge is to answer the question 65 00:02:56,000 --> 00:02:59,000 based on what you learned from this program. 66 00:02:59,000 --> 00:03:01,000 Develop a PowerPoint presentation, 67 00:03:01,000 --> 00:03:05,000 write a report, or even design a piece of artwork. 68 00:03:05,000 --> 00:03:09,000 Students, check out the Earth System Science Song on our website, 69 00:03:09,000 --> 00:03:11,000 developed by Magic State of the Arts 70 00:03:11,000 --> 00:03:13,000 and heard at the end of this program. 71 00:03:13,000 --> 00:03:17,000 It might guide you in finding the answer to your question. 72 00:03:17,000 --> 00:03:20,000 Submit your presentation, report, or artwork 73 00:03:20,000 --> 00:03:22,000 to the NASA Connect website. 74 00:03:22,000 --> 00:03:24,000 There's a good chance that your presentation 75 00:03:24,000 --> 00:03:27,000 will be seen by millions of students across the country. 76 00:03:27,000 --> 00:03:29,000 We look forward to your submittals. 77 00:03:29,000 --> 00:03:32,000 Well, guys, that wraps up another episode of NASA Connect. 78 00:03:32,000 --> 00:03:35,000 We'd like to thank everyone who helped make this program possible. 79 00:03:35,000 --> 00:03:38,000 Got a comment, question, or suggestion?
