00:00:07,540 --> 00:00:13,140
hi everyone welcome to the continuation of our natural science lesson three

2
00:00:13,140 --> 00:00:20,420
groups of invertebrates so in this video we are going to practice the groups three

3
00:00:20,420 --> 00:00:33,340
four five and six so remember there are six groups of invertebrates in the last

4
00:00:33,340 --> 00:00:40,979
video we practice the first one and the second one so the first groups are the

5
00:00:40,979 --> 00:00:53,159
arthropods second group the mollusks the third group is the echinoderms

6
00:00:53,159 --> 00:01:08,299
the fourth group the annelids the fifth group the cnidarians and the sixth

7
00:01:08,299 --> 00:01:34,480
group, the sponges. Mirror word. Six groups of invertebrates, arthropods, mollusks, echinoderms,

8
00:01:34,480 --> 00:01:46,950
Anilids, Cnidarians, Sponges.

9
00:01:48,950 --> 00:01:56,459
So, let's talk about or let's practice the group 3 echinoderms.

10
00:01:57,459 --> 00:02:05,459
Remember, echinoderms have hard, spiky skin.

11
00:02:05,459 --> 00:02:36,680
Echinoderms live on the ocean floor. Mirror word. Group 3. Echinoderms. Echinoderms have hard, spiky skin.

12
00:02:36,680 --> 00:02:46,680
Echinoderms live on the seafloor.

13
00:02:49,039 --> 00:02:54,599
Let's go to group four, Anelids.

14
00:02:57,629 --> 00:03:06,409
Anelids have a soft body and moist skin.

15
00:03:06,409 --> 00:03:24,840
Annihilates can live on land, in water, or inside other animals.

16
00:03:27,949 --> 00:03:28,889
Mirror word.

17
00:03:30,370 --> 00:03:32,710
Group 4. Annihilates.

18
00:03:33,710 --> 00:03:39,669
Annihilates have a soft body.

19
00:03:39,669 --> 00:03:45,210
And moist skin.

20
00:03:46,930 --> 00:04:01,009
Anelites can live on land, in water, or inside other animals.

21
00:04:01,990 --> 00:04:06,949
Group 5, Cnidarians.

22
00:04:06,949 --> 00:04:17,379
Cnidarians have a jelly-like body and tentacles.

23
00:04:20,589 --> 00:04:25,189
Cnidarians live in the sea.

24
00:04:28,259 --> 00:04:32,720
Mirror word, group 5, Cnidarians.

25
00:04:32,720 --> 00:04:44,980
Cnidarians have a jelly-like body and tentacles.

26
00:04:47,199 --> 00:04:52,480
Cnidarians live in the sea.

27
00:04:54,160 --> 00:04:59,680
Group six, sponges.

28
00:04:59,680 --> 00:05:10,279
Sponges can be smooth and mushy.

29
00:05:13,509 --> 00:05:19,649
It can also be rough, hard, and prickly.

30
00:05:22,889 --> 00:05:27,410
Sponges live in water.

31
00:05:30,959 --> 00:05:35,759
Sponges cannot move around.

32
00:05:35,759 --> 00:06:01,500
Mirror word. Group 6. Sponges. Sponges can be smooth and mushy. It can also be rough, hard, and prickly.

33
00:06:01,500 --> 00:06:25,069
sponges live in water sponges cannot move around so let's have a quick practice so you guess okay

34
00:06:25,069 --> 00:06:31,689
you try to figure out the groups of this invertebrates what do they belong to okay

35
00:06:31,689 --> 00:06:47,069
So, let's start with starfish. What does the starfish belong to? Is it echinoderm, annelid, cnidarians, or sponge? What's your guess?

36
00:06:47,069 --> 00:07:05,449
Okay, so echinoderm. How about jellyfish? What does it belong to? Okay, it belongs to the group of Cnidarian.

37
00:07:05,449 --> 00:07:22,180
how about marine sponges what do they belong to okay they belong to the sponges crew how about

38
00:07:22,180 --> 00:07:35,740
this earthworms what group do they belong to okay they belong to the group of annelids okay and I

39
00:07:35,740 --> 00:07:41,819
think that's it thank you for practicing with me bye-bye see you
