Test practice track 3.
2
You will hear a university lecturer giving a talk about teaching physics to children.
3
First, you will have some time to look at questions 1 to 10.
4
Now listen carefully and answer questions 1 to 10.
5
Good afternoon, everyone.
6
We've been looking at different ways that, as teachers, you can make science fun in the classroom.
7
And today I'm going to be talking about physics.
8
Now the concepts of physics can be very difficult for children to understand, but they can also be really fun.
9
So I'm going to describe a few experiments that will show children not only how exciting, but also how useful physics can be.
10
The first experiment is based on what's known as the Brazil nut effect.
11
It came about because physicists wondered why, when you open a container of mixed nuts, the largest Brazil nuts always seem to end up at the top.
12
The great thing is that to demonstrate what's happening, you don't need a lot of equipment.
13
Just a glass jar with a lid, a marble, so just a normal glass marble that children typically play with, and some sand.
14
Just enough to fill the jar about three quarters full, and so there's still room for it to move about easily.
15
Then you put the marble into the jar, put on the lid and shake it vigorously.
16
Now before you show the results, ask your students to try and predict what will happen to the marble as you shake the jar.
17
They're likely to make the same initial assumption as the physicists, which is that because the marble is heavier,
18
it will sink down and end up at the bottom of the jar
19
but in fact no matter how hard you shake it the marble will remain at
20
or near the top that's
21
because with a granular mixture like this the largest particles always end up on top when you shake it
22
now it always helps to increase interest in science
23
if you can show it has a real -world application
24
and in this case it's proven to be very important in the field of healthcare,
25
because scientists realise that if a patient is given medication in a powdered form, and it's made up of components of different densities,
26
then those individual components may not mix together very evenly in the bottle.
27
So they're now very careful to take this into account.
28
Okay, our second experiment is the unpoppable balloon.
29
This one is always fun.
30
It requires an inflated balloon, a pin, and, the secret ingredient, a piece of sticky tape,
31
which you're going to secretly apply to the side of the balloon.
32
So don't show the students you've done this.
33
Again, it's best to invite your class to predict the results.
34
So hold up the balloon and the pin and ask them what will happen when you stick it in the balloon.
35
They'll no doubt tell you that there'll be a very loud bang.
36
However, if you stick the pin into your specially prepared section, to their surprise, rather than bursting,
37
the air will leak out very quietly and slowly, and you can tell your students that when a balloon does burst,
38
it does so faster than the speed of sound, creating a sonic boom.
39
In the real world, this principle is used to test out the limits of different materials
40
and to see just how elastic they are and how much stress can be put on them.
41
The final experiment I want to recommend is great for demonstrating momentum and I call this one the arm engine.
42
To do this experiment, you're going to need a chair that can swivel or rotate as well as some small hand weights.
43
Get one of your students to sit on the chair holding the weights in their hands.
44
Then ask another student to spin the chair as fast as they can.
45
I'm sure your students will love the results of this one because they'll find that, depending on how they hold the weights,
46
the students sitting in the chair will be able to alter their own speed.
47
So when they hold the weights out and make themselves as wide as possible, they'll slow right down.
48
But if they make themselves smaller, with the weights tucked right in next to their body,
49
they'll be amazed to see that they can accelerate and start to spin faster again all by themselves.
50
The whole class is sure to want to try it out.
51
When it comes to the real -world application, tell your students that they can observe this principle at work from watching the ice skating at the Winter Olympics.
52
They'll see how the competitors manage to spin incredibly fast just by tucking their hands in really close to their body.
53
So these are just a few ideas for teaching physics.

動画の背景と概要

この動画では、大学の講師が子どもたちに物理を教える方法として、3つの実験を紹介しています。物理の概念は難しいですが、実験を通して楽しく理解できること、さらには現実世界での応用例も説明されており、英語学習者にとっては科学用語や説明的な表現を学ぶ良い機会です。

日常会話に使える5つのフレーズ

  • end up at the top:上部にたまる。「ブラジルナッツ効果」の説明で使われ、物事の結果を表す際に便利です。
  • take this into account:これを考慮に入れる。医療分野の応用例で登場し、計画や判断をする際の重要なフレーズです。
  • secret ingredient:秘密の材料。風船の実験で使われ、意外な要素を指すのに適しています。
  • alter their own speed:自分の速度を変える。「アームエンジン」の実験で、動作の変化を表現します。
  • slow right down:大幅に減速する。回転する椅子の実験で、速度の変化を説明する際に使えます。

Shadowingのステップバイステップガイド

この動画を使ってshadow speech(シャドーイング)を練習するには、以下の手順を試してみてください。まず、動画を1回全体で聴き、内容を理解します。次に、1文ずつ止めながら、発音やイントネーションを真似て繰り返します。特に「the largest Brazil nuts always seem to end up at the top」のような長い文は、リズムを捉えることが重要です。英語の発音を良くするためには、子音の強弱や母音の長さに注目し、口の形を意識して発声しましょう。

さらに、英語スピーキング練習として、実験の説明部分を自分の言葉で再構成して話してみます。「ブラジルナッツ効果」の応用例を説明する際には、「take this into account」を使ってみるなど、学んだフレーズを活用しましょう。動画で英語学習するメリットは、リアルな発音やスピードに慣れることです。繰り返し練習することで、自然なスピーキング能力が向上します。

最後に、全体を一気に聴きながらシャドーイングを行い、流れに沿って話せるようになるまで練習します。これにより、shadowspeaksの技術が身につき、英語の会話力が飛躍的に向上します。

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。
