Hey guys, it's me, Samara.
2
And I'm Brandon.
3
And welcome back to the Adventure Academy Science Fair.
4
Hey, Samara.
5
I've had a question that's really been bothering me.
6
What's that?
7
Oh, that's a weird one.
8
I was reading about in an article how a scientist in the late 1500s by the name of Galileo, cool name, said that if two objects dropped,
9
one heavy and one light, that gravity would pull them down at the same exact speed.
10
That's correct, but what's got me confused is this.
11
If I drop the rock and the feather at the exact same time, the rock always falls faster.
12
So how could Galileo have been right?
13
Ah, I see.
14
The thing is, when you drop things here on Earth, gravity isn't the only force acting on them.
15
While the force of gravity is pulling them down, The air below them is pushing them up.
16
Scientists call this force air resistance.
17
And back in 1971, astronaut David Scott did the experiment on the moon by dropping a feather and his rock hammer.
18
Since the moon has no air, the feather and the hammer hit the ground at the same time, even though the hammer was much heavier.
19
That seems like something I really want to try out for myself.
20
The eagle has landed.
21
Well, we might not be able to do it with the feather and the rock, but we could do it with a book and a piece of paper.
22
Go on.
23
Okay, hold the book in one hand
24
and the paper in the other at the exact same height and drop them at the same time.
25
You see?
26
The book fell down because it's heavier.
27
Not so fast, oh skeptical one.
28
Put the paper on top of the book.
29
And then see what happens.
30
Okay.
31
What?
32
Whoa, whoa, whoa!
33
How did that happen?
34
Science.
35
When you put the paper on top of the book, the book blocked the air from painting the bottom of the paper.
36
This got rid of the air resistance on the paper.
37
Okay, you convinced me, but I still would like to do this on the moon.
38
Anyway, there you guys go.
39
Another cool science mystery solved with the help of experiments.
40
See you guys next time.
41
Bye!

이 레슨에 대해
"Science Fair: Gravity and Free Fall"으로 쉐도잉 기법을 사용해 영어를 연습합니다.
매일 15~30분 꾸준히 연습하면 IELTS 스피킹에 대한 자신감이 길러집니다.
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
