00:00:00,620 --> 00:00:18,399
Let's start unit 5. Animals. Look at the picture. How many animals can you see there? Can you see the flamingo? Can you see the parrot? Can you see the turtle? Can you see Coco?

2
00:00:18,399 --> 00:00:26,440
First, we have to know what is a vertebrate animal.

3
00:00:27,760 --> 00:00:39,240
Dogs, cows, chickens and horses are vertebrate animals because they have skeletons.

4
00:00:40,259 --> 00:00:42,320
They have spines.

5
00:00:44,659 --> 00:00:46,020
What about humans?

6
00:00:46,359 --> 00:00:48,399
Are we vertebrate animals?

7
00:00:48,399 --> 00:00:55,979
Yes, we are vertebrate animals because we have a spine.

8
00:00:56,600 --> 00:00:58,380
There, can you see it?

9
00:01:00,820 --> 00:01:03,200
What is an invertebrate animal?

10
00:01:05,579 --> 00:01:16,620
Butterflies, starfish, scorpions, worms and jellyfish are invertebrate animals.

11
00:01:16,620 --> 00:01:20,439
They haven't got any skeletons.

12
00:01:21,079 --> 00:01:23,939
They haven't got any spines.

13
00:01:30,569 --> 00:01:34,510
Which vertebrate animals are we going to study in this unit?

14
00:01:35,489 --> 00:01:39,489
We are going to study mammals like the wolf,

15
00:01:41,090 --> 00:01:41,969
birds,

16
00:01:43,969 --> 00:01:44,810
reptiles,

17
00:01:45,750 --> 00:01:47,989
and amphibians.

18
00:01:51,030 --> 00:01:53,049
First, mammals.

19
00:01:53,049 --> 00:01:59,989
Look at the pictures. There are some giraffes, a lion, and humans.

20
00:02:01,810 --> 00:02:09,569
Mammals are vertebrates. Mammals are viviparous. They drink their mother's milk.

21
00:02:10,490 --> 00:02:14,530
Most mammals have four legs and hair.

22
00:02:15,370 --> 00:02:18,469
Look at the girl. She has blonde hair.

23
00:02:18,469 --> 00:02:30,069
look at the lion he has lot it has lots of fur giraffes also have fur now look

24
00:02:30,069 --> 00:02:38,550
at the giraffes again they have one two three four legs can you see them look at

25
00:02:38,550 --> 00:02:46,330
the lion we can see the legs but we know that the lion has four legs and we

26
00:02:46,330 --> 00:02:58,759
humans how many legs do we have now let's see birds can you see the dog can

27
00:02:58,759 --> 00:03:04,300
you see penguin birds are vertebrates birds are

28
00:03:04,300 --> 00:03:22,080
vipers birds have wings most birds can fly birds have two legs and feathers now

29
00:03:22,080 --> 00:03:42,580
Reptiles. Look at the snake. Look at the lizard. And look at the turtle. Reptiles are vertebrates. Reptiles are oviparous. They have scales. Look at the snake. Can you see the scales?

30
00:03:42,580 --> 00:03:56,000
Some reptiles slither, like the snake and the lizard, but the turtle, does it slither or does it swim?

31
00:03:56,000 --> 00:04:13,919
Hmm, now amphibians. Amphibians are vertebrates. Amphibians are viperous. They lay eggs in water.

32
00:04:13,919 --> 00:04:28,980
they have wet skin most amphibians have four legs look at the frog how many legs has it got one two

33
00:04:28,980 --> 00:04:41,160
three four okay this is it I hope you have enjoyed with this presentation see you next week bye
