Previous knowledge: in the 1st lesson students learnt the main feautres of vertebrate animals.

2. Vertebrate animals: amphibians

Presentation 

Students watch this video that contains the main characteristics of Amphibians

Hello everybody! Today we’re going to look at a truly amazing group of vertebrates... When they’re born they usually live in water... but when they grow up and become adults they spend most of their time on land. We present - the Amphibians!
All amphibians have some common characteristics that you should know about so you can recognize and differentiate them.
Amphibians have thin, bare skin, with no hairs and scales to protect them. Most have four legs and a membrane between their toes that allows them to move much better in the water.
Amphibians are oviparous, but they don’t incubate their eggs after laying them... they abandon them and don’t care for their young. Not very good parents, huh?
When they hatch, they’re small larvae and live in water. Slowly... very slowly... their bodies go through a process called metamorphosis.
During this process, the body of the amphibian... changes... their front and rear legs, their limbs, grow... and their heads and their bodies develop, so they finally look like their parents.
In the early stages of their lives... amphibians breathe through gills, but when they grow up and become adults... they breathe with their lungs. The problem is, their lungs are very small, and cannot get all the oxygen they need to live. But nature is very clever... and has solved this problem by allowing them to breathe and get the oxygen they need... through their skin. That’s why they need to be near water - to keep their skin wet.
In the early stages of their life, some amphibians are herbivores, but when they grow up... most become carnivores. So they need to hunt...
Some have a long, sticky tongue they shoot out to capture prey.
Aren’t amphibians fascinating? And also a bit strange?!
So let’s remember the most important characteristics...
Amphibians are vertebrates; they’re oviparous; in the early stages of their life they live in water as larvae, but slowly they change until they look just like their parents. This process of change is called metamorphosis.
Amphibians are carnivores, so they have to hunt to eat; they have thin, smooth skin, and breathe through their skin and with their lungs.
Amphibians are so interesting, aren’t they?

Practice 

Students read the following text about amphibians.

What makes and amphibian?

Amphibians are animals that live part of their lives in water and part on land.  They usually have soft, moist skin that is protected by a slippery layer of mucus. They also tend to live in moist places or near water to keep their bodies from drying out. There are three main groups of amphibians: caecilians; salamanders, newts, and mudpuppies; and frogs and toads.

All amphibans: 

Now you are ready to work on the following activities where you will have to put your knowledge about amphibians in action.

Crossword about amphibians

Fill the gaps

PRODUCTION

Select one amphinian and crete a mind map where there must be included information related to feeding, breathing and reproduction of the selected amphibian.

To carry out this activity students will use the text2mindmal

Here you have a tutorial to use text2mindmap

 

0:00
all right as we're seeing here is the web two point on O'Toole the text to
0:07
mind map it's an online graphic organizer creator and it's free with no
0:12
membership required so i suggest that you take advantage of it
0:16
the key to text mind map is simplicity this web 2.0 tool is very simple and for
0:24
somebody who's not very good with technology you can definitely work your
0:32
way around this because I can a lot of people use it to make my maps out of
0:37
bulleted lists as you can see here on the left is the bulleted list listing
0:44
the months of the year how i can edit that is i can go ahead and delete this
0:49
and put mine in and it will show up like this and what you can do is go to
0:57
options and we can go ahead and pull these out so i did my header hello and
1:06
goodbye in different languages and I did Spanish English and Chinese you can move
1:13
it around to adjust it any way you want it funky or more in order i kinda like
1:20
this look to it
1:22
so what i can do is lock all and they can still be moved around right now but
1:29
they don't shake i can go in edit the font so go ahead and do this one and
1:37
then see sometimes it spreads you can just go ahead and put some more i can
1:43
change the size i'll go ahead and keep them on 23 so the route i can change
1:54
color you can go ahead and just make it any color you want i'm gonna go ahead
2:03
and book
2:05
and you can change the branches up as well now I can also change the line
2:13
color I want them to look a little more distinct i'll go ahead and make them
2:17
dark black can also change the width I'll go Ahead's go with medium and that
2:29
is really all you need to do in mind texting mind map down here you can save
2:37
and by saving you can change the title to your map and you can also put in your
2:43
email in case you lose the map and so i'll just put in email address and save
2:57
the mindmap alright that is not working but what will happen is if you just give
3:05
an email address it will give you an URL that you can see then come back to the
3:09
email address is just so if you lose that URL they can help you find it by
3:15
sending you an email for it
3:16
you can also zoom in i forgot to show you that and zoom out and then you can
3:25
also download it you can just download the image or download PDF this makes it
3:30
really nice for printing so yeah I would say overall educators can really benefit
3:41
from using this program it's a great program to use like with a smartboard
3:46
when you have the entire class and you're trying to brainstorm a topic or
3:50
concept it can save a lot of time because you can go ahead and copy and
3:54
paste an outline into a text five from a text file into the empty column on the
3:59
left right here like I did and it's nice that you can save it as a PDF file
4:07
students can just you know refer back to it whenever they need to and i also
4:14
think it's great for working in small groups
4:17
if a student if students are working together on a project they can organize
4:22
and manage it by making a text mind map it's also great for as a guide for
4:27
writing when students are mapping out the ideas and topics they want to write
4:34
about and this is also just great for visual learners there are some drawbacks
4:39
to it as you can see here this space is only so big if your list gets to be more
4:48
than about 18 lines long you'll then have to start scrolling up and down
4:53
through it and it can get really busy on here but then you can just zoom out and
5:01
one other drawback is that they only have the tree format which can kind of
5:06
be a limitation when trying to do some really serious work but other than that
5:12
I think it's a great simple web 2.0 tool and i would definitely suggest using
5:17
this in your classroom
