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!

シャドーイングとは?英語上達に効果的な理由
シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
