00:00:34,229 --> 00:00:32,229
hello my name is shane kimbrough and i'm

3
00:00:36,389 --> 00:00:34,239
an astronaut living and working up here

4
00:00:37,990 --> 00:00:36,399
on the international space station

5
00:00:40,229 --> 00:00:38,000
in this demonstration i'll be talking

6
00:00:42,549 --> 00:00:40,239
about the five main senses we have and

7
00:00:46,709 --> 00:00:42,559
how we use them up here on the station

8
00:00:51,430 --> 00:00:49,029
as humans we have five senses that let

9
00:00:54,389 --> 00:00:51,440
us observe the world around us

10
00:00:56,549 --> 00:00:54,399
these senses are sight taste smell

11
00:00:58,790 --> 00:00:56,559
hearing and touch

12
00:01:01,430 --> 00:00:58,800
our senses help us determine whether or

13
00:01:03,910 --> 00:01:01,440
not we like something but they also warn

14
00:01:05,990 --> 00:01:03,920
us if something is wrong

15
00:01:07,830 --> 00:01:06,000
sometimes our senses pick up very good

16
00:01:11,510 --> 00:01:07,840
things like the smell of fresh baked

17
00:01:13,750 --> 00:01:11,520
cookies or the taste of yummy pizza

18
00:01:15,270 --> 00:01:13,760
other times our centers may warn us of

19
00:01:18,230 --> 00:01:15,280
danger like the smell of something

20
00:01:19,830 --> 00:01:18,240
burning or the feeling of something hot

21
00:01:22,310 --> 00:01:19,840
let's go through the five senses and

22
00:01:26,149 --> 00:01:22,320
talk about what we may observe with them

23
00:01:28,310 --> 00:01:26,159
up here on the station

24
00:01:31,910 --> 00:01:28,320
the sense of sight allows us to see the

25
00:01:33,590 --> 00:01:31,920
world around us or in my case space

26
00:01:35,350 --> 00:01:33,600
here on the station one way we use our

27
00:01:37,510 --> 00:01:35,360
sense of sight is to see different

28
00:01:40,630 --> 00:01:37,520
experiments we are working on so we can

29
00:01:42,310 --> 00:01:40,640
report the results back to earth some

30
00:01:43,670 --> 00:01:42,320
astronauts have noticed that their site

31
00:01:45,910 --> 00:01:43,680
changes a little after living in

32
00:01:47,749 --> 00:01:45,920
microgravity aboard the station

33
00:01:49,590 --> 00:01:47,759
scientists are helping to fix this by

34
00:01:51,710 --> 00:01:49,600
conducting research up here on

35
00:01:54,230 --> 00:01:51,720
astronauts like me

36
00:01:57,109 --> 00:01:54,240
[Music]

37
00:01:59,109 --> 00:01:57,119
our sense of taste comes from our tongue

38
00:02:00,630 --> 00:01:59,119
and it tells our brain what kind of food

39
00:02:01,590 --> 00:02:00,640
and nutrients we are putting into our

40
00:02:03,109 --> 00:02:01,600
body

41
00:02:06,389 --> 00:02:03,119
we can tell when something is super

42
00:02:07,910 --> 00:02:06,399
sweet or very salty because of this

43
00:02:10,229 --> 00:02:07,920
because of fluid shifts on a space

44
00:02:12,710 --> 00:02:10,239
station sometimes our noses can be a bit

45
00:02:13,910 --> 00:02:12,720
stuffy and it can be harder to taste

46
00:02:14,949 --> 00:02:13,920
food

47
00:02:17,350 --> 00:02:14,959
so

48
00:02:22,390 --> 00:02:17,360
lots of us love to add hot sauce to many

49
00:02:27,110 --> 00:02:25,190
smell just like with taste sometimes our

50
00:02:29,190 --> 00:02:27,120
sense of smell can change up here in

51
00:02:30,790 --> 00:02:29,200
microgravity as the liquids in our body

52
00:02:32,229 --> 00:02:30,800
move around

53
00:02:34,150 --> 00:02:32,239
once our bodies have adjusted to

54
00:02:38,550 --> 00:02:34,160
microgravity the space station has a

55
00:02:43,110 --> 00:02:40,869
hearing in terms of hearing inside the

56
00:02:45,030 --> 00:02:43,120
space station there is constant noise

57
00:02:47,670 --> 00:02:45,040
coming from the different machines that

58
00:02:48,869 --> 00:02:47,680
keep our air flowing and the experiments

59
00:02:50,550 --> 00:02:48,879
running

60
00:02:53,110 --> 00:02:50,560
our sleeping quarters block some of the

61
00:02:55,589 --> 00:02:53,120
noise though so we're able to get a good

62
00:02:57,030 --> 00:02:55,599
night's sleep each night

63
00:02:59,270 --> 00:02:57,040
what do you think you would hear outside

64
00:03:01,110 --> 00:02:59,280
the space station well you better be

65
00:03:03,589 --> 00:03:01,120
wearing a spacesuit so you'd be hearing

66
00:03:05,750 --> 00:03:03,599
the fan noises inside the spacesuit but

67
00:03:07,350 --> 00:03:05,760
if somehow you were able to be outside

68
00:03:09,910 --> 00:03:07,360
of that space suit you would hear

69
00:03:12,309 --> 00:03:09,920
absolutely nothing because sound cannot

70
00:03:13,220 --> 00:03:12,319
travel in space because it has no air to

71
00:03:14,790 --> 00:03:13,230
travel through

72
00:03:16,550 --> 00:03:14,800
[Music]

73
00:03:18,630 --> 00:03:16,560
touch usually when you think of touch

74
00:03:20,869 --> 00:03:18,640
you think of observing how things feel

75
00:03:22,630 --> 00:03:20,879
with your fingers since we are floating

76
00:03:24,869 --> 00:03:22,640
we are constantly having to touch and

77
00:03:27,270 --> 00:03:24,879
grab onto objects either using our hands

78
00:03:29,589 --> 00:03:27,280
or our feet you can use your feet to

79
00:03:31,430 --> 00:03:29,599
walk up here if you carefully hook them

80
00:03:33,110 --> 00:03:31,440
under hand rails as you go but this is

81
00:03:34,630 --> 00:03:33,120
pretty challenging so we like to use our

82
00:03:36,149 --> 00:03:34,640
hands more than our feet while we're up

83
00:03:37,750 --> 00:03:36,159
here

84
00:03:40,660 --> 00:03:37,760
we will often use our hands to move

85
00:03:46,710 --> 00:03:40,670
along and carry objects with our legs

86
00:03:50,630 --> 00:03:48,390
thanks for learning about the five main

87
00:03:52,949 --> 00:03:50,640
senses with me today start thinking

88
00:03:54,390 --> 00:03:52,959
about your five senses and how they help

89
00:03:56,309 --> 00:03:54,400
you observe and adapt to your

90
00:03:59,660 --> 00:03:56,319
environment down on earth

91
00:04:15,670 --> 00:03:59,670
see you next time
