2. Vertebrate animals: amphibians


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?

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


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


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