Shadowing Practice: Over (to) The Moon: Crash Course Kids #13.2 - Learn English Speaking with Video

Creating lesson...
1
You know how many people have actually been on the Moon?
2
Twelve. That's all.
3
But one day, we may go back there.
4
We have a lot more to learn about the Moon and space in general.
5
So some day, maybe in your lifetime, we'll send astronauts out there to study and explore.
6
Do you want to be one of them?
7
If you do, let me give you some helpful tips about a little thing called gravity, because you're going to need to know all about what gravity is and how it works if you're going to escape the pull of Earth and fly to the Moon.
8
Now, you already know that astronauts can leave the Earth, but it takes a lot of effort to boldly go where few have gone before.
9
But once astronauts reach the speed called escape velocity, they're able to overcome the force of Earth's gravity and get into orbit around our planet or head on over to the Moon.
10
So, this brings up an interesting question: what happens when an object gets away from Earth's gravity, but close to the moon's gravity?
11
You already know that gravity is the force that keeps us from flying off the surface of the Earth.
12
And you know that gravity pulls things, not down, but towards the Earth's center.
13
You also know that gravity exists between any objects that have mass, and the greater an object's mass is, the greater the effect of its gravity, or pull on other objects, is.
14
But there's something more.
15
Remember Isaac Newton, the apple tree guy?
16
He determined that the amount of gravitational force, or pull, between two objects also depends on how far apart they are.
17
So the farther away something is from the Earth, the less it will feel the pull of Earth's gravity.
18
And the closer it gets to the Moon, the more it will feel the Moon's gravity pulling on it.
19
Let's do a little pretending to see what happens to something when it moves closer to an object that has a really large mass, and therefore, a really strong pull of gravity.
20
If you've ever made a wish on a shooting star, you've seen the effect of Earth's gravity pulling on an object.
21
Shooting stars, which are actually meteors, occur when pieces of rock break off from a passing comet or asteroid and get too close to the Earth.
22
For example, say this globe represents the Earth, and the marble represents a piece of space rock that's flying by.
23
You can see that there's a huge difference in size between the two objects.
24
And, if we were to put them on a scale, we'd see that there's a big difference in their mass too.
25
Our model Earth has a larger mass.
26
If the space rock is far away from the Earth, then it can go on its merry way, since it won't be affected by the Earth's gravity.
27
But if it gets too close, then it and the Earth engage in a bit of tug-of-war, since both have gravity that pull on one another.
28
It's not much of a fight though.
29
The more massive Earth has a much larger gravitational pull, so the rock gets caught in Earth's gravity, and most of the time, it gives us a brilliant streak of light we call a meteor.
30
But what does this mean for our space travelers?
31
Well when an astronaut ship takes off for the Moon and moves away from the Earth, the farther away it goes, the less it feels the pull of Earth's gravity.
32
And, as it gets closer to the Moon, the spaceship begins to feel the tug of the Moon's gravity more.
33
So even though the Moon has a smaller mass than the Earth, and has less of a pull on the ship than the Earth does...
34
once the ship gets closer to the Moon than the Earth, the Moon's gravity pulls the ship toward it.
35
And then the astronauts can make a safe landing!
36
So we can make the argument that two things affect the pull of gravity: First, the size of the object.
37
Objects with a bigger mass have a stronger pull of gravity.
38
And second, the distance between objects.
39
The farther apart objects are, the weaker the pull of gravity between them, and the closer together they are, the stronger the pull of gravity.
40
All of this means that when the day comes that you're flying a spaceship to the Moon, you just have to escape Earth's gravity, and then get close enough to the Moon to enter its gravity.
41
Remember that when you're grown up, and you're welcome.
42
If you wanna thank me, you could just name a crater or something after me when you get there.

About This Lesson

In this lesson, you will practice your English listening and speaking skills as you explore the fascinating topic of gravity and space travel. The video discusses the mechanics of gravity, how it affects objects as they move away from Earth, and the challenges astronauts face when traveling to the Moon. By engaging with this content, you will enhance your vocabulary related to space, develop your comprehension of scientific explanations, and improve your pronunciation through shadowing practice.

Key Vocabulary & Phrases

  • Gravity: The force that pulls objects toward one another, particularly toward the center of the Earth.
  • Escape velocity: The minimum speed needed for an object to break free from Earth’s gravitational pull.
  • Meteor: A piece of space rock that enters the Earth's atmosphere and creates a bright streak of light.
  • Mass: The amount of matter in an object; larger mass results in a stronger gravitational pull.
  • Pull of gravity: The force of attraction between two objects with mass.
  • Space rock: Asteroids or meteors that exist in outer space.
  • Astronaut: A person who travels into space to study or explore.
  • Orbit: The path an object takes as it revolves around another object in space.

Practice Tips

To effectively use this video for your English learning, consider employing the shadowing technique. This method involves repeating what you hear in real-time, which can help you develop a natural speaking rhythm and improve your pronunciation.

Here are some specific tips for practicing with this video:

  • Start by listening to the video without looking at the transcript to grasp the overall meaning. This will help you build your comprehension skills.
  • Play the video again, this time with the transcript open. Identify key vocabulary and focus on their pronunciation.
  • Use a shadowing app to help you track your performance as you mimic the speaker. Aim to match their tone and speed for effective practice.
  • If the pace feels challenging, slow down the video to capture every word accurately before attempting to keep up.
  • Once you feel comfortable, try to summarize the main points of the video in your own words, which will aid your IELTS speaking practice.
  • Finally, record yourself speaking, and play it back to assess your articulation and fluency. This can help you recognize areas for further improvement.

By practicing these techniques, you will enhance your conversational skills, making it easier to discuss complex topics like space exploration with confidence in English.

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.
