1
00:00:13,039 --> 00:00:09,290
this may look like a big inflated trash

2
00:00:15,499 --> 00:00:13,049
bag well it sort of is but beyond that

3
00:00:17,900 --> 00:00:15,509
it is a unique setting used to introduce

4
00:00:20,330 --> 00:00:17,910
students to star patterns and let them

5
00:00:22,460 --> 00:00:20,340
create their own constellation stories

6
00:00:24,710 --> 00:00:22,470
this activity integrated science

7
00:00:26,990 --> 00:00:24,720
language arts and gives do these

8
00:00:30,800 --> 00:00:27,000
opportunity to show their creations to

9
00:00:33,319 --> 00:00:30,810
everyone on home made planetarium it's a

10
00:00:37,100 --> 00:00:33,329
great activity to use at school with a

11
00:00:38,180 --> 00:00:37,110
club during a family event but first we

12
00:00:41,920 --> 00:00:38,190
fulfilled

13
00:00:44,990 --> 00:00:41,930
planetarium you'll need a few supplies a

14
00:00:48,080 --> 00:00:45,000
20 by 50 foot roll of 4 mil plastic

15
00:00:50,420 --> 00:00:48,090
sheet be sure to get at least 4 mil

16
00:00:53,750 --> 00:00:50,430
thickness any thinner and your planetary

17
00:00:56,600 --> 00:00:53,760
may let in too much light in addition

18
00:00:59,299 --> 00:00:56,610
you'll need a roll of utility tape a

19
00:01:02,599 --> 00:00:59,309
single black plastic trash bag ballpoint

20
00:01:05,090 --> 00:01:02,609
pen scissors and a box cutter it's best

21
00:01:07,880 --> 00:01:05,100
to have at least one person to help you

22
00:01:13,050 --> 00:01:07,890
construct the planetarium start by

23
00:01:21,310 --> 00:01:16,390
then fold it in half as shown to create

24
00:01:23,110 --> 00:01:21,320
a 20 by 25 foot rectangle next tape the

25
00:01:26,080 --> 00:01:23,120
top sheet to the bottom sheet on all

26
00:01:28,390 --> 00:01:26,090
three sides of the rectangle using a

27
00:01:30,970 --> 00:01:28,400
French fold to tape the sheets together

28
00:01:34,570 --> 00:01:30,980
will ensure that no separation occurs

29
00:01:37,210 --> 00:01:34,580
later you can see here that the tape

30
00:01:39,640 --> 00:01:37,220
will contact three surfaces of plastic

31
00:01:41,670 --> 00:01:39,650
when placed on a French fold though a

32
00:01:46,270 --> 00:01:41,680
bit tricky this technique is very

33
00:01:50,240 --> 00:01:46,280
important complete the taping on all

34
00:01:56,040 --> 00:01:53,340
once the taping is complete walk on all

35
00:01:58,500 --> 00:01:56,050
the tape scenes to secure them now it's

36
00:02:02,880 --> 00:01:58,510
time to attach the fan fold over one

37
00:02:05,250 --> 00:02:02,890
corner of the planetarium cut off the

38
00:02:09,270 --> 00:02:05,260
bottom of the plastic bag creating a

39
00:02:12,150 --> 00:02:09,280
tube place the open to a plastic bag

40
00:02:16,020 --> 00:02:12,160
down on the planetarium cut a hole the

41
00:02:19,410 --> 00:02:16,030
size of plastic bag in only one layer of

42
00:02:22,710 --> 00:02:19,420
the planetarium take one end the plastic

43
00:02:25,680 --> 00:02:22,720
bag tube to the hole put the other end

44
00:02:29,190 --> 00:02:25,690
of the plastic bag tube on the fan and

45
00:02:32,180 --> 00:02:29,200
take security fan should be facing so

46
00:02:34,650 --> 00:02:32,190
that it will glow into the planetarium

47
00:02:38,190 --> 00:02:34,660
turn the fan on high and watch the

48
00:02:41,100 --> 00:02:38,200
planetarium inflate once the planetarium

49
00:02:43,620 --> 00:02:41,110
is inflated turn the fan on low cut a

50
00:02:45,210 --> 00:02:43,630
hole for a door an inverted T design

51
00:02:47,400 --> 00:02:45,220
works nicely for a door

52
00:02:50,610 --> 00:02:47,410
I suggest placing the door as far away

53
00:02:52,950 --> 00:02:50,620
from the fan as is reasonable once the

54
00:02:58,309 --> 00:02:52,960
door is cut turn the fan back on high

55
00:03:03,869 --> 00:03:01,110
our ancient ancestors used nighttime

56
00:03:05,819 --> 00:03:03,879
stars to create stories this activity

57
00:03:08,039 --> 00:03:05,829
students will create their own stories

58
00:03:17,190 --> 00:03:08,049
and draw a pattern of stars on the

59
00:03:19,020 --> 00:03:17,200
lesson template before entering or

60
00:03:21,179 --> 00:03:19,030
taking students into the planetarium

61
00:03:23,909 --> 00:03:21,189
make sure you have a flashlight and

62
00:03:26,369 --> 00:03:23,919
scissors or box cutter for emergency

63
00:03:28,259 --> 00:03:26,379
exits if needed black plastic has been

64
00:03:30,809 --> 00:03:28,269
checked by safety experts and is non

65
00:03:33,619 --> 00:03:30,819
flammable the fan provides very good

66
00:03:37,199 --> 00:03:33,629
ventilation for up to 15 students and

67
00:03:40,140 --> 00:03:37,209
now for the star patterns the ballpoint

68
00:03:42,539 --> 00:03:40,150
pen or straight paperclip can be used to

69
00:03:45,599 --> 00:03:42,549
punch holes in plastic with a twisting

70
00:03:48,119 --> 00:03:45,609
motion students use their constellation

71
00:03:51,390 --> 00:03:48,129
sheets as templates to transfer their

72
00:03:53,849 --> 00:03:51,400
constellation to the plastic seal from

73
00:03:58,820 --> 00:03:53,859
the inside the resulting holes appear to

74
00:04:03,800 --> 00:04:01,040
once everyone has created their

75
00:04:07,210 --> 00:04:03,810
constellations on the planetarium enjoy

76
00:04:09,440 --> 00:04:07,220
some time together sharing the stories

77
00:04:11,360 --> 00:04:09,450
students can display and read their

78
00:04:14,200 --> 00:04:11,370
story to others and have fun while

79
00:04:17,050 --> 00:04:14,210
practicing creative writing skills I

80
00:04:20,629 --> 00:04:17,060
like drawing the picture and then

81
00:04:22,550 --> 00:04:20,639
looking at the sky seeing everyone's

82
00:04:25,250 --> 00:04:22,560
um different constellations

83
00:04:28,250 --> 00:04:25,260
what I liked best was booking the stars

84
00:04:30,620 --> 00:04:28,260
in the sky the black plastic planetarium
