00:00:00.080 --> 00:00:03.270
When the Earth goes dark for a few minutes during a

2
00:00:03.270 --> 00:00:06.450
total solar eclipse, animals, plants,

3
00:00:06.450 --> 00:00:09.650
and environmental conditions react.

4
00:00:09.650 --> 00:00:12.850
In the path of the eclipse, temperatures and clouds can change quickly.

5
00:00:12.850 --> 00:00:16.040
But exactly how they change is a question NASA

6
00:00:16.040 --> 00:00:18.240
scientists are trying to answer.

7
00:00:18.240 --> 00:00:21.330
If you’ll be in North America during the August 21 eclipse,

8
00:00:21.330 --> 00:00:24.510
you can help NASA collect data for a citizen science project

9
00:00:24.510 --> 00:00:27.690
that’s looking at how much cooler the Earth gets during the eclipse

10
00:00:27.690 --> 00:00:30.890
by measuring air temperature and clouds.

11
00:00:30.890 --> 00:00:33.080
How can you help?

12
00:00:33.080 --> 00:00:37.280
First, download the free GLOBE Observer app on to your smartphone or tablet.

13
00:00:37.280 --> 00:00:40.340
Second, get a thermometer to measure air temperature.

14
00:00:40.340 --> 00:00:43.510
See our website or app for suggestions about the types you can get.

15
00:00:43.510 --> 00:00:46.700
The app will walk you through how and when

16
00:00:46.700 --> 00:00:48.890
to make your scientific observations.

17
00:00:48.890 --> 00:00:51.960
Your data will go into the GLOBE Program’s database

18
00:00:51.960 --> 00:00:55.140
where it’s accessible to students and scientists from all over the world.

19
00:00:55.140 --> 00:00:58.320
Scientists can use this data to study how

20
00:00:58.320 --> 00:01:01.510
our solar-powered planet is affected by this special celestial event.

21
00:01:01.510 --> 00:01:04.550
You can collect data in many locations.

22
00:01:04.550 --> 00:01:07.740
The path of totality is roughly 70 miles wide and

23
00:01:07.740 --> 00:01:10.760
stretches across the continental United States

24
00:01:10.760 --> 00:01:12.940
from Oregon to South Carolina.

25
00:01:12.940 --> 00:01:16.150
Outside of this path, the rest of the continental U.S.

26
00:01:16.150 --> 00:01:18.330
and other areas will see a partial eclipse

27
00:01:18.330 --> 00:01:20.540
where you can still collect data.

28
00:01:20.540 --> 00:01:22.560
We are looking forward to your observations

29
00:01:22.560 --> 00:01:24.660
download the app, create an account,

30
00:01:24.660 --> 00:01:28.840
and be ready to take part on August 21st.

31
00:01:28.840 --> 00:01:30.858
