Hello class, it's teacher Shaila. Today we're going to start a new topic together

2
00:00:06,559 --> 00:00:15,199
and learn all about tools and machines. Please turn to page 96 in your natural science book

3
00:00:15,759 --> 00:00:23,359
and let's get started. In this unit you will learn all about tools and machines.

4
00:00:23,359 --> 00:00:33,359
Tools and machines are used by humans to help them do things and lift things and move faster.

5
00:00:33,359 --> 00:00:49,270
Go to activity one. You will look at the picture above, listen, and circle the tools and machines that I say.

6
00:00:51,179 --> 00:01:06,140
We have a washboard, a bicycle, a plow, a radio, and a telephone.

7
00:01:07,659 --> 00:01:13,260
This is an old telephone. It looks very different from the ones that we use today.

8
00:01:16,650 --> 00:01:22,569
Now let's go to exercise two. Look at the machine in the picture.

9
00:01:22,569 --> 00:01:35,299
what's this old machine? Tick the correct answer, then write the word of the machine. If you think

10
00:01:35,299 --> 00:01:46,019
and remember, you will know that computers and tablets are very new. They are new inventions

11
00:01:46,019 --> 00:01:53,840
and new machines that have only been made about 20 years ago. So they are new.

12
00:01:53,840 --> 00:02:02,819
They are not old. However, a telephone was created about a hundred and fifty years

13
00:02:02,819 --> 00:02:12,659
ago. That is a very long time ago. So we will tick telephone and we will write

14
00:02:12,659 --> 00:02:25,439
It's a telephone. This old version of a telephone has a dial, a cord, and a

15
00:02:25,439 --> 00:02:34,219
mouthpiece. It looks very different from the mobile phone that we use at home or

16
00:02:34,219 --> 00:02:42,020
bring with us from place to place to communicate. Now let's go forward to

17
00:02:42,020 --> 00:02:51,639
exercise three. Listen while I explain each machine and tool and match them to

18
00:02:51,639 --> 00:03:04,189
their correct picture. A wheel turns in a circle. This is a wheel so we can connect

19
00:03:04,189 --> 00:03:15,370
to wheel. Bicycle. You can ride a bicycle from place to place and in the park.

20
00:03:15,370 --> 00:03:28,969
Radio. We listen to the radio for news and music. Washing machine. We put our

21
00:03:28,969 --> 00:03:38,930
clothing into the washing machine to clean our clothes. And plow. This is a

22
00:03:38,930 --> 00:03:53,569
plow. We use a plow to help us farm. Next we can try to mime a tool or machine. So

23
00:03:53,569 --> 00:03:59,129
think of all of these different tools and machines that we have just reviewed

24
00:03:59,129 --> 00:04:10,569
and try to guess what tool or machine I am miming, I am acting out, okay? Now look

25
00:04:10,569 --> 00:04:19,410
at me acting out or miming using a invention and machine and you can guess

26
00:04:19,410 --> 00:04:32,339
what machine I am using, okay? Hello, good to talk to you. How are you today?

27
00:04:32,339 --> 00:04:44,199
Oh, that's great. Okay, thank you for calling. Okay, bye-bye. What machine was that that

28
00:04:44,199 --> 00:04:57,300
I was using? Yes, excellent. It is a telephone. Good work, class. Let's continue forward with

29
00:04:57,300 --> 00:05:01,160
the exercises and thank you for learning with me. Bye-bye.
