00:00:00,050 --> 00:00:02,410
Today we have video number five

2
00:00:10,529 --> 00:00:16,809
Use this part of our cardboard so the remaining part under

3
00:00:17,870 --> 00:00:18,949
cnidarians

4
00:00:18,949 --> 00:00:26,719
This is what we're gonna do today for the lab book. Okay about the worms. What we need to do is a

5
00:00:27,440 --> 00:00:29,079
clam shell

6
00:00:29,079 --> 00:00:36,619
Opening okay, we're going to do something like this. Okay, so just follow my instruction to first do the foldings

7
00:00:36,759 --> 00:00:40,020
Okay, but it needs to end up like this

8
00:00:40,320 --> 00:00:46,520
okay, so the first thing we need to take is a piece of paper a white paper and measure on a square of

9
00:00:47,140 --> 00:00:51,060
15 centimeters long 15 15 because it's on a square

10
00:00:51,560 --> 00:00:56,399
Okay, when you have it ready you cut it. Okay fit here

11
00:00:56,399 --> 00:01:10,040
okay and you will need to fold it in half when you fold it in half then you need to fold it back

12
00:01:10,040 --> 00:01:23,719
again okay and when it's ready open okay you see the marks here okay now we're gonna make a

13
00:01:23,719 --> 00:01:42,780
triangle triangle here okay so we have all the parts settle okay now we have all the different

14
00:01:42,780 --> 00:01:49,379
folds here okay okay I have discovered that you need to fold it in this direction okay so when

15
00:01:49,379 --> 00:01:54,879
When you have it ready, what you need to do is to put the things inside and you finally

16
00:01:54,879 --> 00:01:57,019
get the clamp.

17
00:01:57,019 --> 00:02:04,000
So when you finished making all the foldings, you are going to write outside here Worms.

18
00:02:04,000 --> 00:02:10,360
Remember this part, the opposite to the Worms, we are going to glue it to the lab book.

19
00:02:10,360 --> 00:02:17,900
So this will be Worms and when we open, we need to mark these four parts.

20
00:02:17,900 --> 00:02:24,659
is here and we mark these four parts that we are going to divide our flap

21
00:02:24,659 --> 00:02:31,639
okay so here is what we need to have inside our foldings okay so remember we

22
00:02:31,639 --> 00:02:37,340
need to have worms here on the front part this will be the opposite will be

23
00:02:37,340 --> 00:02:42,740
the part that we stick to our lab book and when we open we need to have

24
00:02:42,740 --> 00:02:47,500
something like this okay so first thing we're going to divide into four

25
00:02:47,500 --> 00:02:55,860
different parts the same as here okay four four okay so let's start here with

26
00:02:55,860 --> 00:03:01,979
the flat worms okay I have to say that worms is a very diverse group okay we

27
00:03:01,979 --> 00:03:07,219
have very different types of animals and they are in different types of groups

28
00:03:07,219 --> 00:03:13,039
okay so we have here some of the most common ones okay so we start with the

29
00:03:13,039 --> 00:03:19,159
flat worms they are worms that as the name say they are flat okay most of them

30
00:03:19,159 --> 00:03:24,139
are parasites and but the difference with the other groups that we have

31
00:03:24,139 --> 00:03:28,439
studied the boryphor and the neidarian system these they have nervous system

32
00:03:28,439 --> 00:03:33,060
okay what is represented here is the nervous system an example of this we

33
00:03:33,060 --> 00:03:39,939
have the tapeworm, it is a parasite, in Spanish we call it tenia, and the planaria, those are two

34
00:03:39,939 --> 00:03:47,259
parasites that humans can have. Then we have the nematodes, they have unsegmented cylindrical

35
00:03:47,259 --> 00:03:54,360
bodies, so they are round worms, but they do not have segments. Examples, the intestinal worms,

36
00:03:54,360 --> 00:04:00,759
I'm sure to some of you, your family has said, don't do that, because if you do that, you will

37
00:04:00,759 --> 00:04:05,300
have is intestinal worms. These are the worms that you have if you have them.

38
00:04:05,300 --> 00:04:10,879
Also the anisakis that is a very common one that is in the fish and

39
00:04:10,879 --> 00:04:15,280
some of your family might have and you have to be careful with the

40
00:04:15,280 --> 00:04:22,660
fish. Then we have the annelids. The difference with the

41
00:04:22,660 --> 00:04:28,300
other two groups is that they have segmented bodies. Bodies divided into

42
00:04:28,300 --> 00:04:34,379
two parts. We have three different groups, okay? We have the polychets, the oligochets,

43
00:04:34,379 --> 00:04:41,420
and the iridinians. So, the polychets are most of the marine, example we have the

44
00:04:41,420 --> 00:04:47,379
nereids, the oligochets, we have the earthworm, the typical, lombriz de tierra,

45
00:04:47,379 --> 00:04:53,259
okay? The typical one is an oligochet, and the iridinian, example leeches, leeches

46
00:04:53,259 --> 00:05:01,680
are sanguijuelas, okay, the one that suck the blood, okay, and there are other groups of worms,

47
00:05:02,319 --> 00:05:07,879
there are many, many, many different type of groups of worms, I think I have some examples here,

48
00:05:08,220 --> 00:05:15,759
for example, the rotifers, we have the micrognathozoa, gastrotrix, endoprocta, etc.,

49
00:05:15,759 --> 00:05:21,980
okay, these are examples, okay, of other groups that we have, what you have to learn very well

50
00:05:21,980 --> 00:05:25,980
are the flatworms, the nematodes are the anelites.

51
00:05:51,980 --> 00:05:52,959
Thank you.
