Shadowing Practice: Why is hot air WAVY? (only for curious) - Learn English Speaking with Video

Creating lesson...
1
Do you remember when you are driving on the road
2
and it's a sunny day and the air in the distance seems kind of wavy?
3
Or when you are sitting at a campfire and the air right above the campfire is somehow blurred?
4
I always questioned this as a kid, but now that I have all the knowledge that I need to explain it to myself, and I believe you do too, I never bothered to do so.
5
And even though I'm not the smartest person of all, I tried to break it down into few simple terms to be able to explain it to you.
6
Since the air is hotter, it has more heat.
7
And heat is just a form of energy.
8
And that energy actually transforms even into speed.
9
So the molecules of the air, in the hotter air, are a lot faster.
10
But because they are faster, they tend to push into each other a lot more.
11
And because they push with faster speeds, they actually push a lot stronger.
12
And because they push a lot stronger, they actually start to bump into each other into much bigger distances.
13
And what this causes is a much lower density of the air because it's just a lot more spread out.
14
So the density of the air only depends on how hot it is.
15
And because the hotter air is actually getting created on the ground where the heat is coming from, the lowest layer of the air actually has the least amount of density.
16
So what it automatically does is it starts exchanging with the layer that is above it because it has more density.
17
So it exchange.
18
And once it starts exchanging, you can see
19
that what starts happening is this chain reaction of the air actually starting to form these lines
20
that are going above and each other.
21
But then if we don't see air, how are we seeing this change? something called refraction of light
22
comes into play refraction is the process of bending light waves
23
and all that determines how the light comes into our eyes is the substance
24
that it comes through in this case either hot air
25
or cold air if you can imagine these hot
26
and cold layers of air actually exchanging constantly
27
and the light passing through them it actually isn't going straight
28
what it is doing is it's constantly bending through these layers
29
so and so because the light that is delivered then to our eyes bent
30
so many times before it came into our eyes our brain
31
automatically perceives the coming thing as a bit of vibrating and so that's why it always seems a bit wavy.
32
But if this is true, have you ever seen this happen with cold air?

Step-by-step Shadowing Guide

To effectively use the shadowing technique while engaging with this video, follow these steps to improve your English pronunciation and speaking skills:

  1. Watch the video once: Familiarize yourself with the overall content and context without worrying about every word.
  2. Listen carefully: Replay the video, paying attention to the nuances in pronunciation and intonation.

  4. Break it down: If certain phrases are challenging, isolate them. For example, practice saying “the molecules of the air” repeatedly until you feel comfortable.
  5. Use shadowspeaks: Incorporate the phrases learned into daily conversations. Try to explain similar concepts to friends or family, which will reinforce your understanding and improve your fluency.

By adopting this structured approach, you can effectively enhance your English speaking capabilities while enjoying the learning process. Remember, consistent practice using shadowing can lead to significant improvements in pronunciation and communication skills!

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.
