Shadowing Practice: Science in English #3 | The Periodic Table - Learn English Speaking with Video
Creating lesson...
1
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.

Vocabulary and speaking notes for this lesson
This B1 speaking lesson is built on the video “Science in English”. The speaker keeps coming back to these words: element, atomic, table, periodic, metals. This video has 57 sentences and 427 words to shadow. The speech runs for 3:40. The speaker talks at a steady 117 words per minute, a comfortable pace for shadowing. Only 81% of the words are among the 3,000 most common in English, so the vocabulary is demanding.

- Record yourself and compare with the original, paying attention to words like atomic, periodic, nonmetal.
What is the Shadowing Technique?
Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
