Shadowing Practice: Candy Corn In Space - Learn English Speaking with Video
Ders oluşturuluyor...
1
When astronauts go up in space, they're allowed to bring some special items.
2
Some astronauts fly M&Ms, some people fly beef jerky.
3
Don Pettit, this guy, chose candy corn.
4
He's a NASA astronaut who spent nearly half a year floating around the International Space Station.
5
And while he was up in space...
6
I elected to spend my off-duty time doing science of my own design.
7
this zero gravity candy corn demonstration.
8
It's a macroscopic analogy to how a surfactant molecule works.
9
And a surfactant molecule just means...
10
Soap.
11
So in this demo, a candy corn is equivalent to a soap molecule.
12
And this water blob represents grease or oil.
13
And basically the demo shows how soap cleans grease.
14
Soap molecules have a water loving end...
15
So they call that hydrophilic...
16
And a water water-hating end.
17
Hydrophobic.
18
And that's important.
19
Say you have a blob of oil and you throw it in a washing machine, the hydrophobic part of the molecule sticks into the grease and the oil,
20
and the hydrophilic part pokes up into the water.
21
In candy corn, the hydrophobic, hydrophilic sides are reversed.
22
This part is water-loving, and Pettit coated this side with oil to make it water-hating.
23
But the principle is the same.
24
The molecules or the candy corn arrange themselves around the glob based on attraction or repulsion to water.
25
Of course, that's how your clothes get clean.
26
You cover them with these hydrophilic, hydrophobic molecules called soap.
27
And once the soap molecules fully cover the grease blob, it becomes water-soluble.
28
It's called the critical micelle concentration.
29
Or in candy corn.
30
The critical candy corn concentration.
31
Once it hits this concentration.
32
All the dirt and the oil and the grease floats off of your fabric, and it mixes with the water, and then you pour the water off, and you're left with clean clothes.
33
Now in candy corn, there's a bonus science lesson.
34
After you reach the critical candy corn concentration, And a most amazing thing happens.
35
The blob goes from smushy to rigid.
36
You can think of it like...
37
Of putting the keystone in a Roman arch, where now all of a sudden gravity locks all the stones together, and you have this rigid arch that you could drive traffic across.
38
But we're in space, so it's not gravity at work.
39
It's surface tension holding the ball together.
40
This was one of many experiments Pettit did in space, but it's the only one that used candy corn.
41
I used our whole crew's supply of candy corn for this one demonstration, which I profusely apologized to the rest of the crew because they didn't get to eat any.
42
For Science Friday, I'm Flora Lichtman.
43

Gölgeleme Tekniği Nedir?
Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
