Ahem.
2
Good morning, everyone.
3
Today we are going to learn about the periodic table.
4
Think of it as a map of all known elements.
5
Just like a map helps you find places, the periodic table helps scientists organize the building blocks of matter.
6
Let's get started.
7
Let's begin with a simple comparison.
8
The English language has only 26 letters.
9
Yet, those 26 letters can create millions of words and sentences.
10
Nature is very similar.
11
About 118 elements combine to create everything around us.
12
So where can we find all these elements?
13
We can find them in the periodic table.
14
Let's begin with our learning objectives.
15
By the end of this lesson, you will understand what the periodic table is.
16
You will learn about atomic number and atomic mass.
17
You will also identify groups and periods.
18
Finally, you will recognize metals, nonmetals, and metalloids.
19
So what is the periodic table?
20
It is a chart that organizes all known elements.
21
Each element has four important pieces of information.
22
Its name, its chemical symbol, its atomic number, and its atomic mass.
23
Now let's look more closely at these numbers.
24
The atomic number is like an ID card.
25
It tells us exactly which element it is.
26
For example, hydrogen has an atomic number of one.
27
Carbon has an atomic number of six.
28
has an atomic number of 1.
29
Carbon has an atomic number of 6.
30
Gold has an atomic number of 79.
31
The atomic mass tells us how heavy an atom is compared with a hydrogen atom.
32
Not all elements are the same.
33
Scientists divide them into three main categories.
34
Metals Metals are usually shiny and conduct electricity well.
35
Nonmetals do not conduct electricity well.
36
Metalloids have properties of both metals and nonmetals.
37
Each category has its own unique properties.
38
Now let's learn how to read the periodic table.
39
The horizontal rows are called periods.
40
The vertical columns are called groups.
41
Here is an important idea.
42
Elements in the same group have similar properties.
43
They behave in similar ways during chemical reactions.
44
Let's look at a few examples.
45
Group 1 contains the alkali metals.
46
They are very reactive.
47
Group 17 contains the halogens.
48
They are reactive non-metals.
49
Group 18 contains the noble gases.
50
These elements are very stable and rarely react with other elements.
51
Let's review what we have learned today.
52
The periodic table organizes all known elements.
53
Each element has an atomic number and an atomic mass.
54
The table is arranged into periods and groups.
55
Elements in the same group have similar properties.
56
The periodic table helps scientists understand and compare all known elements.
57
Thank you for listening.

  3. 自分の声を録音して元の音声と比べます。atomic, periodic, organizeなどの単語に特に注意しましょう。

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。
