WEBVTT FILE 1 00:00:00.000 --> 00:00:03.340 If you’ve been watching this series, you know that NASA has 2 00:00:03.340 --> 00:00:07.500 scientists posted all over the world studying Earth’s frozen regions. 3 00:00:07.500 --> 00:00:14.670 We’ve got people exploring ice sheets, glaciers, permafrost, sea ice, snow and even ice on other planets! 4 00:00:14.670 --> 00:00:17.850 But even our top scientists need a little back-up sometimes. 5 00:00:17.850 --> 00:00:20.410 I’m a scientist! 6 00:00:20.410 --> 00:00:28.330 7 00:00:28.330 --> 00:00:30.540 Cryosphere 8 00:00:30.540 --> 00:00:33.290 9 00:00:33.290 --> 00:00:35.390 Cryo Kids: Bonus Episode 10 00:00:35.390 --> 00:00:40.030 11 00:00:40.030 --> 00:00:41.580 Do you like going outside to do science? 12 00:00:41.580 --> 00:00:42.450 Yeah. 13 00:00:42.450 --> 00:00:43.910 Why? 14 00:00:43.910 --> 00:00:45.490 Cuz it's fun. 15 00:00:45.490 --> 00:00:47.160 Yeah? What’s your favorite part? 16 00:00:47.160 --> 00:00:48.510 Frost tube. 17 00:00:48.510 --> 00:00:50.540 Frost tube! Cool! 18 00:00:50.540 --> 00:00:54.620 In this bonus episode of Cryosphere, we’re following the micro-explorers 19 00:00:54.620 --> 00:00:59.180 that are helping NASA collect data from their own backyard 20 00:00:59.180 --> 00:01:01.200 Do you think it’s going to be frozen? 21 00:01:01.200 --> 00:01:02.400 Yeah. 22 00:01:02.400 --> 00:01:03.100 Yeaaaaah! 23 00:01:03.100 --> 00:01:04.040 Why? 24 00:01:04.040 --> 00:01:08.040 Because it’s very frozen! 25 00:01:08.040 --> 00:01:08.640 26 00:01:08.640 --> 00:01:12.530 Here’s the idea: students construct a Frost Tube that get put into a 27 00:01:12.530 --> 00:01:15.540 hole in undisturbed and un-compacted soil. 28 00:01:15.540 --> 00:01:20.840 During the cold months, students will measure the depth at which water in the Frost Tube freezes, 29 00:01:20.840 --> 00:01:24.120 indicating that the surrounding soil has frozen. 30 00:01:24.120 --> 00:01:28.330 This is one of many citizen science projects facilitated by GLOBE, 31 00:01:28.330 --> 00:01:32.380 the Global Learning and Observations to benefit the Environment Program. 32 00:01:32.380 --> 00:01:33.490 What’s going on? What did you -- 33 00:01:33.490 --> 00:01:35.530 It’s turning into ice! 34 00:01:35.530 --> 00:01:37.790 How far down is the ice? 35 00:01:37.790 --> 00:01:38.740 36 00:01:38.740 --> 00:01:41.360 Whoa!

They're outside, it's obviously really cold 69 00:03:42.310 --> 00:03:46.510 but everyone is so excited to be out there making measurements for NASA 70 00:03:46.510 --> 00:03:48.350 That’s wicked cool 71 00:03:48.350 --> 00:03:51.000 Because you’re so right, science is so fun 72 00:03:51.000 --> 00:03:54.810 I really hope that you'll continue believing in that 73 00:03:54.810 --> 00:04:00.340 The best piece of advice I ever got was that whatever you do, do your best 74 00:04:00.340 --> 00:04:04.450 And from all of us here at the Jet Propulsion Laboratory, remember: 75 00:04:04.450 --> 00:04:08.100 Dare mighty things! 76 00:04:08.100 --> 00:04:09.790 So keep up the great work! 77 00:04:09.790 --> 00:04:11.840 Make sure that you're having fun no matter what 78 00:04:11.840 --> 00:04:14.560 That’s the key thing about pursuing a career in science 79 00:04:14.560 --> 00:04:16.410 Make sure it’s something you love 80 00:04:16.410 --> 00:04:20.820 And I'm really impressed. So hopefully, we'll take the lessons you're learning 81 00:04:20.820 --> 00:04:24.670 and apply them when we explore our solar system 82 00:04:24.670 --> 00:04:29.069
