Hi, today we are going to learn about energy. 00:00:00
Our objectives for today is that our students, at the end of the lesson, are able to define 00:00:06
energy, describe the two main forms of energy, and give examples of the two main forms of 00:00:12
energy. 00:00:20
But, here comes our first question, what do you use the word energy for? 00:00:21
Talk to your partner and give at least three examples of when you use the word energy. 00:00:29
When you eat, your body breaks the food down and gives you energy. 00:00:39
When you are outside, the sun gives you energy in the form of light and heat. 00:00:45
And the street lights use electrical energy to give us light. 00:00:52
Talk to your partner again, do you know now something else about energy you didn't know 00:00:58
before? 00:01:04
So, what's energy? 00:01:05
Well, energy is defined as the ability to do work. 00:01:10
Energy is what makes things move, change and carry out work. 00:01:17
You can jump, ride a bike and play because of energy. 00:01:22
And what are the forms of energy? 00:01:29
Well, to be honest, there are quite a lot of forms of energy. 00:01:32
In this unit, we are going to study up to eight, but today we are going to focus on 00:01:37
the main two, kinetic and potential. 00:01:45
Look at this picture, what can you see in them? 00:01:50
Yeah, the girl on the left is still, she's not moving. 00:01:55
But the children on the right, they are moving. 00:02:01
So the girl who is still has potential energy, she's not moving, she's still. 00:02:06
While the boys, the children who are moving, they have kinetic energy. 00:02:16
Potential energy is store energy, while kinetic energy is moving energy. 00:02:25
Let's practice that. 00:02:33
Look at the picture, is the ball moving? 00:02:34
No, it's still. 00:02:38
So if the ball is still, it's, yeah, that's right, potential energy. 00:02:40
Check the bike now, is the bicycle moving? 00:02:50
No, it's at the top of the hill, so the bicycle is not moving, potential kinetic. 00:02:53
Yeah, that's right, potential too. 00:03:00
But when the bike starts moving downhill, its potential energy becomes kinetic energy. 00:03:03
Let's recap. 00:03:13
If an object is still or stationary, it has store energy, also called potential energy. 00:03:15
But if an object is moving, that is in motion, it has kinetic energy. 00:03:24
The faster it moves, the more kinetic energy it has. 00:03:31
Let's play a game, check this picture. 00:03:37
Kinetic or potential energy? 00:03:41
Is the arrow moving? 00:03:44
No, it's not. 00:03:47
Well done. 00:03:49
Let's try this new one. 00:03:51
Is the ball moving? 00:03:54
Yeah, it's moving, so it must be kinetic. 00:03:56
Well done. 00:03:59
What about this other one? 00:04:01
Is the bicycle in motion? 00:04:03
Is it moving? 00:04:05
Yeah, it seems so. 00:04:05
Kinetic then? 00:04:07
Yeah. 00:04:09
What about this one? 00:04:11
Is the pack moving or is it still? 00:04:12
Still, potential then. 00:04:17
Wow, we're on fire. 00:04:20
And what about this one? 00:04:23
Is the golf ball moving or still? 00:04:24
It's still, potential then. 00:04:27
Yeah. 00:04:30
And what about the ball? 00:04:32
Is the volleyball moving or is it still? 00:04:33
Yeah, it must be moving, it's on the earth. 00:04:36
Yay, well done. 00:04:38
