00:15
I'm a huge believer in hands-on education.
0
0
3000
Би дадлагаар боловсрол
олгохыг маш их дэмждэг.
00:19
But you have to have the right tools.
1
4000
2000
Гэвч танд зөв хэрэгсэл хэрэгтэй.
00:21
If I'm going to teach my daughter about electronics,
2
6000
3000
Би охиндоо электроникийн тухай заахдаа
00:24
I'm not going to give her a soldering iron.
3
9000
2000
гагнуурын төхөөрөмж өгөхгүй.
00:26
And similarly, she finds prototyping boards
4
11000
2000
Эх хавтан ч мөн адил
00:28
really frustrating for her little hands.
5
13000
3000
түүний бяцхан гарт ахадна.
00:31
So my wonderful student Sam and I
6
16000
3000
Ингээд би өөрийн нэг мундаг
сурагч болох Сэмтэй хамт
00:34
decided to look at the most tangible thing we could think of:
7
19000
2000
хамгийн бодит зүйлийг
сонирхохоор боллоо.
00:36
Play-Doh.
8
21000
2000
Энэ бол Плэй-до баримлын шавар.
00:38
And so we spent a summer
9
23000
2000
Ингээд нэг зуныг
00:40
looking at different Play-Doh recipes.
10
25000
2000
янз бүрийн Плэй-доны жор
судалж өнгөрөөлөө.
00:42
And these recipes probably look really familiar
11
27000
2000
Энэ жорнууд урд нь гар аргаар хийж үзсэн
00:44
to any of you who have made homemade play-dough --
12
29000
2000
хүмүүст танил харагдах байх.
00:46
pretty standard ingredients you probably have in your kitchen.
13
31000
3000
Гал тогоонд чинь байдаг гарын доорх
материалууд байгаа.
00:49
We have two favorite recipes --
14
34000
2000
Бидэнд таалагдсан 2 төрлийн жор байна.
00:51
one that has these ingredients
15
36000
2000
Нэг нь ийм найрлагатай,
00:53
and a second that had sugar instead of salt.
16
38000
2000
нөгөө нь давсны оронд элсэн чихэртэй.
00:55
And they're great. We can make great little sculptures with these.
17
40000
3000
Үүгээр гайхалтай жижигхэн
баримлууд хийж болно.
00:58
But the really cool thing about them is when we put them together.
18
43000
3000
Хамгийн сонирхолтой зүйл
энэ хоёрыг нийлүүлэх үед болно.
01:01
You see that really salty Play-Doh?
19
46000
2000
Тэр давстай Плэй-дог харж байна уу?
01:03
Well, it conducts electricity.
20
48000
2000
Тэр цахилгаан дамжуулдаг.
01:05
And this is nothing new.
21
50000
2000
Энэ шинэ зүйл биш.
Дэлгүүрээс авдаг Плэй-до
цахилгаан дамжуулдаг юм байна.
01:07
It turns out that regular Play-Doh that you buy at the store conducts electricity,
22
52000
2000
01:09
and high school physics teachers have used that for years.
23
54000
3000
Дунд сургуулийн физикийн багш нар
олон жил үүнийг хэрэглэсэн.
Гэвч бидний гараар зуурсан нь
01:12
But our homemade play-dough
24
57000
2000
худалдаанд байдгаас 2 дахин бага
цахилгааны эсэргүүцэлтэй.
01:14
actually has half the resistance of commercial Play-Doh.
25
59000
2000
01:16
And that sugar dough?
26
61000
2000
Харин чихэртэй зуурмагны тухайд,
01:18
Well it's 150 times more resistant to electric current
27
63000
2000
давстай зуурмагаас 150 дахин илүү
01:20
than that salt dough.
28
65000
2000
эсэргүүцэлтэй.
01:22
So what does that mean?
29
67000
2000
Энэ юу гэсэн үг вэ?
01:24
Well it means if you them together you suddenly have circuits --
30
69000
3000
Тэр хоёрыг нийлүүлэхэд цахилгаан
хэлхээ бий болно гэсэн үг.
01:27
circuits that the most creative, tiny, little hands
31
72000
3000
Энэ хэлхээг хамгийн бүтээлч,
бяцхан гарнууд
01:30
can build on their own.
32
75000
3000
өөрсдөө бүтээж чадна.
01:33
(Applause)
33
78000
5000
(Алга ташилт)
01:38
And so I want to do a little demo for you.
34
83000
3000
Би та бүхэнд жижигхэн үзүүлэн харуулъя.
01:42
So if I take this salt dough,
35
87000
2000
Би энэ давстай зуурмагийг аваад,
01:44
again, it's like the play-dough you probably made as kids,
36
89000
2000
та нар багадаа хийж байсан байх,
01:46
and I plug it in --
37
91000
2000
үүнийг энгийн нэмэх хасах цэнэгтэй
01:48
it's a two-lead battery pack, simple battery pack,
38
93000
3000
зайнд залгая.
01:51
you can buy them at Radio Shack
39
96000
2000
Энийг "Радио Шэк" дэлгүүр болон
01:53
and pretty much anywhere else --
40
98000
2000
бусад ихэнх дэлгүүрээс авах боломжтой.
01:55
we can actually then
41
100000
3000
Энэ зайг ашиглан
01:58
light things up.
42
103000
3000
гэрэл асааж болно.
02:02
But if any of you have studied electrical engineering,
43
107000
2000
Гэхдээ та нар дотор
цахилгааны инженер байвал
02:04
we can also create a short circuit.
44
109000
2000
богино холбоо үүсгэж болно.
02:06
If I push these together, the light turns off.
45
111000
3000
Энэ хоёрыг нийлүүлж дарахад гэрэл унтарна.
02:09
Right, the current wants to run through the play-dough, not through that LED.
46
114000
2000
Яг зөв, гүйдэл LED гэрэл биш,
зуурмагаар дамжина.
02:11
If I separate them again, I have some light.
47
116000
2000
Дахин салгахад, гэрэл гарна.
02:13
Well now if I take that sugar dough,
48
118000
2000
Харин чихэртэй зуурмаг
02:15
the sugar dough doesn't want to conduct electricity.
49
120000
2000
цахилгаан дамжуулдаггүй.
02:17
It's like a wall to the electricity.
50
122000
2000
Энэ яг цахилгааны хана гэсэн үг.
02:19
If I place that between, now all the dough is touching,
51
124000
3000
Үүнийг дунд нь байрлуулан,
бүхлээр нь хүргэнэ.
02:22
but if I stick that light back in,
52
127000
2000
Ингээд гэрэл залгахад
02:24
I have light.
53
129000
2000
асчихлаа.
02:26
In fact, I could even add some movement to my sculptures.
54
131000
3000
Тэр ч байтугай барималдаа
хөдөлгөөн нэмж болно.
02:29
If I want a spinning tail, let's grab a motor,
55
134000
2000
Ямар нэг зүйл эргэлдүүлэхийг хүсвэл
мотор залгаад
02:31
put some play-dough on it, stick it on
56
136000
3000
бага зэрэг Плэй-до дээр нь
тавьж шургуулахад
02:34
and we have spinning.
57
139000
2000
эргэлдэж эхэлнэ.
02:36
(Applause)
58
141000
4000
(Алга ташилт)
02:40
And once you have the basics,
59
145000
2000
Ингээд суурь мэдлэгтэй болсон бол
02:42
we can make a slightly more complicated circuit.
60
147000
2000
илүү төвөгтэй хэлхээ хийж болно.
02:44
We call this our sushi circuit. It's very popular with kids.
61
149000
3000
Бид үүнийг суши хэлхээ гэж нэрлэсэн.
Хүүхдүүд маш их дуртай.
02:47
I plug in again the power to it.
62
152000
3000
Дахин цахилгаанд залгая.
02:50
And now I can start talking about parallel and series circuits.
63
155000
3000
Одоо зэрэгцээ ба цуваа
холбооны тухай зааж болно.
02:53
I can start plugging in lots of lights.
64
158000
3000
Би зөндөө олон гэрэл залгаж болно.
02:58
And we can start talking about things like electrical load.
65
163000
3000
Тэгээд цахилгааны ачааллын
тухай ярьж эхэлнэ.
03:01
What happens if I put in lots of lights
66
166000
2000
Хэрвээ би олон гэрэл,
03:03
and then add a motor?
67
168000
2000
бас мотор нэмбэл яах бол?
03:05
It'll dim.
68
170000
2000
Гэрэл нь бүдгэрнэ.
03:07
We can even add microprocessors
69
172000
3000
Тэр байтугай бичил процессор нэмж,
03:10
and have this as an input
70
175000
2000
оролттой болгоод,
03:12
and create squishy sound music that we've done.
71
177000
3000
энгийн дуу үүсгэгч хийлээ.
03:15
You could do parallel and series circuits
72
180000
2000
Та бүхэн зэрэгцээ болон цуваа холбоог
03:17
for kids using this.
73
182000
3000
хүүхдүүдэд ингэж үзүүлж болно.
03:20
So this is all in your home kitchen.
74
185000
3000
Энэ бүхэн гэрийн чинь галын өрөөнд байгаа.
03:23
We've actually tried to turn it into an electrical engineering lab.
75
188000
3000
Үнэндээ бид цахилгаан инженерийн
лаборатори бий болгохыг оролдсон.
03:26
We have a website, it's all there. These are the home recipes.
76
191000
3000
Бид цахим хуудастай.
Энд гар аргаар хийх жорнууд байгаа.
03:29
We've got some videos. You can make them yourselves.
77
194000
2000
Видео бичлэгүүд бас байгаа.
Өөрсдөө хийх боломжтой.
03:31
And it's been really fun since we put them up to see where these have gone.
78
196000
3000
Үр дүнгээ харахад үнэхээр сайхан байдаг.
03:34
We've had a mom in Utah who used them with her kids,
79
199000
2000
Юта мужийн хүүхдүүдтэйгээ
хийсэн ээжээс эхлээд
03:36
to a science researcher in the U.K.,
80
201000
2000
Их Британий шинжлэх ухаан судлаач,
03:38
and curriculum developers in Hawaii.
81
203000
3000
Хавайн сургалтын хөтөлбөр
боловсруулагчид хүртэл хийсэн.
03:41
So I would encourage you all to grab some Play-Doh,
82
206000
2000
Иймд би та нарыг зуурмаг,
03:43
grab some salt, grab some sugar and start playing.
83
208000
3000
давс болон чихэр аваад тоглож
эхлэхийг санал болгож байна.
03:46
We don't usually think of our kitchen as an electrical engineering lab
84
211000
3000
Бид галын өрөөгөө цахилгаан
инженерийн лаборатори болгож
эсвэл хүүхдүүдийг зохион
бүтээгч мэт төсөөлдөггүй.
03:49
or little kids as circuit designers,
85
214000
2000
03:51
but maybe we should.
86
216000
2000
Магадгүй тэгж эхлэх хэрэгтэй байх.
03:53
Have fun. Thank you.
87
218000
2000
Цагийг зугаатай өнгөрүүлээрэй.
Баярлалаа
03:55
