Hello, it's not my walking time yet, but pretty soon I will go out now
00:00:00
You have to take all the materials
00:00:07
We are starting with the birth rates that I know that most of you are the kind of group that you like the most
00:00:10
Okay, we start with the characteristics and then with the fish
00:00:15
Okay, we're back with our lab books and we're gonna use this part for the birth rates
00:00:27
okay let me explain you what we're gonna do okay remember all this part has to be free okay we'll
00:00:34
need to write here vertebrates but be careful not to go too low if not you won't have space for
00:00:40
these groups okay so the first thing is we leave this part out okay because this is for mammals
00:00:47
and we are not here yet okay this part we're going to divide it this is about
00:00:56
a four centimeters wide okay four centimeters this part okay so four
00:01:04
centimeters we take and make a line here and the rest we divide it into four
00:01:11
parts okay the rest that is remaining from these four centimeters we make a
00:01:16
across when you finish with the division we start with the characteristics okay we're gonna make
00:01:21
something like this an accordion okay accordion let me show you like
00:01:28
this one okay so basically we're going to have more or less half piece of paper okay
00:01:35
Okay, and in fact this is 11 centimeters and 4 centimeters. I repeat, 11, 4. Okay, and then you need to fold it 5 times. 1, 1, 2, 3, 4, 5.
00:01:42
Be careful because the last one, we need to leave two centimeters here, okay?
00:02:04
And when you finish folding, it is when you have to cut this part, okay?
00:02:12
Don't do it until you don't finish with the foldings.
00:02:21
I suppose you have finished with your flaps, so you should have something like this, more or less, okay?
00:02:24
with these two centimeters that on this part is what we're gonna glue on our notebooks, oh sorry
00:02:32
notebooks, no, lab books, okay, but wait until we finish writing all this information here, okay,
00:02:40
so when we have folded, look, I have a small part here on the front, I write characteristics of
00:02:47
vertebrates, okay, characteristics of vertebrates, that's what I write here, okay, since we're going
00:02:54
to glue it on our notebook like this, okay, that's why I wrote in this direction, and also
00:03:02
I have uploaded in Diabla Virtual these pictures, okay, we are going to use the first two rows,
00:03:09
okay, here, it will appear on the right part of the screen, the picture that you need to
00:03:18
glue on each of the squares. Let's start with the characteristics. So, the first one, and the one
00:03:24
why we are called vertebrates, is because we have internal skeleton. We have an skeleton inside our
00:03:32
body, which are the bones. Basically, all vertebrates have backbones, okay? The backbones
00:03:39
are the ones that we have here at the back. Okay? And we have here that picture. Great.
00:03:45
Then, nervous system. We have a nervous system consisting of the brain and the spinal cord that
00:03:53
also goes on the back of our body inside our backbones. And the picture is that our skin
00:04:01
and the skin of all vertebrates is for sensation and protection. You can see beautiful scales
00:04:10
all the snakes. We have a closed circulatory system. In invertebrates we have both an open
00:04:17
and closed circulatory system, but all the vertebrates have a closed circulatory system.
00:04:24
And finally we have sexual reproduction, usually with separate sexes. It's true that some fish can
00:04:31
be hermaphrodites. But most of the animals, most of the bird breeds have
00:04:39
separate sexes, like chicken and hen. Okay? So let's work!
