Unit 3: Animals

1. Classify these animals into these two groups:

hen – octopus – ant – toad – shark – parrot – snail - ladybird

VERTEBRATES INVERTEBRATES

1. VERTEBRATES AND INVERTEBRATES

Animals are living creatures. They are born, grow,

reproduce and die.

We classify animals into 2 big groups:

o Vertebrate animals:

Vertebrates have a skeleton inside them.

An important part of this skeleton is the

backbone.

Most vertebrates have a head, a trunk, limbs and

a tail.

o Invertebrate animals have not got bones.

2. Read and complete these sentences:

________animals have got bones. The following are vertebrate

animals:______________________________________.

___________animals ________got bones. The following are

invertebrate animals _____________________________.

3. Draw a vertebrate and an invertebrate animal and write

their names into the boxes.

4. Write HAVE or DON´T HAVE to make true sentences:

Dogs _____________________ a tail

Birds _____________________ a backbone

Rabbits _____________________ a tail

Bears _____________________ limbs

Snakes _____________________ limbs

Fish _____________________ backbone

Frogs _____________________ a tail

5. Classify these animals according where they are born from.

Duck-tiger-snake-elephant-whale -bear-leopard-lizard-seagull-

dolphin

OVIPAROUS VIVIPAROUS

6. Write the word that doesn’t belong.

a) turtle, toad, fish, goat _____________________________

b) shark, dolphin, chicken, salmon ________________________

c) seagull, eagle, bat, frog ______________________________

2.-OVIPAROUS AND VIVIPAROUS ANIMALS

According to where animals are born from we can classify

them in:

Oviparous: They are born from an egg. Examples: fish,

frogs and chickens.

Viviparous: They are born from their mother’s womb.

Examples: zebras, whales, bats and “humans”.

4

3. VERTEBRATES

We can classify vertebrates into 5 groups: mammals, fish,

birds, amphibians and reptiles.

Mammals

Mammals are viviparous.

Most have hair or fur.

Some live in the water, but most live on land.

Some can fly.

Fish

Fish are oviparous. They are born from eggs.

They have scales.

They live in water.

Birds

Birds are oviparous.

They have feathers.

Most birds can fly.

Amphibians

Amphibians are oviparous.

They don’t have scales or hair. They just have skin.

They live in water and on land.

Reptiles

Reptiles are oviparous.

They have scales. Some have a shell.

Some live in water, but most live on land.

Some have four legs and walk like crocodiles and

chameleons. Others slither along the ground, like the

snake.

7. Write IS or ISN´T:

It ________viviparous. It ________ viviparous.

It ________oviparous. It ________oviparous.

It ________a water animal. It ________a water animal.

It ________ a water animal. It ________ a water animal.

It ________ a fish. It ________ a fish.

It ______ a reptile It ______ a reptile

It __________a turtle. It __________a turtle.

It _________ a goat. It _________ a goat.

8. Read and circle the correct words. Then colour the picture.

“My name is Max. I am a fox / pig / chick . I am a bird

/mammal / reptile , because I drank / ate my mother’s milk

when I was a child / baby . I am a vertebrate / invertebrate

animal. This means that I have / haven’t a skeleton made of

many muscles / bones / joints . I live on land / in water. I am

a wild / domestic animal”.

9. Read, draw and colour.

Spiky is a parrot, so he is a bird.

He lives in the jungle, in a very tall and green tree.

He has got five white eggs in his nest.

He has got a big, red beak and two orange legs.

His body is covered with feathers. His body is green and

his wings are colourful.

Today is sunny and Spiky is flying in the sky.

10. Label this picture. You can use the words in the box.

eye – gills – mouth – fin – scales

11. Write TRUE or FALSE.

Fish have hair.

Fish are oviparous

Fish are vertebrate animals.

Fish have wings.

They have fins.

They live in water and on land.

They have scales.

Tuna, whale, shark and salmon are fish.

12. Draw these animals in the correct box: snake- turtle- lizard-

crocodile.

WALK SLITHER

13. Look at the life cycle of a frog and try to answer the

questions. Then colour the picture.

4.- INVERTEBRATES

Those animals that haven’t got a skeleton inside them are

invertebrates.

They are usually smaller than vertebrates.

All invertebrates are oviparous.

Most animals on the Earth are invertebrates.

Some are land animals and some are water animals.

5.- CLASSIFIYING INVERTEBRATES

It is more difficult to classify invertebrates because

there are so many groups!

The most important groups are:

Molluscs

Have a soft, muscular body.

Some, like snails, have a shell.

Mussels, oysters and octopuses are all molluscs.

Arthropods

Is the biggest group of invertebrate.

Their bodies are divided into 3 parts.

Insects and arachnids are arthropods.

Insects have six legs and two antennae.

Worms

Have a long soft body.

They don’t have shells.

Jellyfish Sponges Starfish

15. Label this picture and colour it. You can use the words in the box.

17. Classify these animals:

mosquito – snake – toad – fly – horse – ant – lizard – bat

whale – koala – salmon – penguin – duck – crocodile

shark – chameleon – hen – frog – dog – ladybird - butterfly

mammals fish amphibians reptiles birds arthropods

18. Use the information to make a true sentence about each animal.

19. Match.

herbivore carnivore omnivore

Elephants

Pigs

don’t eat

only other animals.

only plants.

plants and other animals

6.-WHAT DO ANIMALS EAT?

According to what they eat we can classify animals in:

Herbivores: Are those who only eat plants, like rabbits

Carnivores: Are those who only eat meat, like lions.

Omnivores: Are those who eat plants and meat, like bears

I eat insects.

I eat fruits and seeds.

I eat roots, fruits and fish.

12

20. Guess the animal.

It is an animal that is vertebrate, carnivore, oviparous, whose body is covered

in scales and live in the water._____________________________________

It is an animal that is vertebrate, herbivore, viviparous, whose body is covered

in fur and lives in land __________________________________________

It is an animal that is vertebrate, carnivore, oviparous, whose body is covered

in feather and lives in water and on land _____________________________

21. Think and answer:

Octopuses are in this group. ______________________________________

Snails are in this group. _________________________________________

Spiders are in this group. ________________________________________

Insects are in this group. ________________________________________

Sponges are in this group. _______________________________________

They only live in the sea. ________________________________________

This is the biggest group of invertebrates. ___________________________

22. Match.

7.-WHERE DO ANIMALS LIVE?

Domestic animals live near people, and some of them give us food.

Example, hens give us eggs.

Pets are domestic animals that live in our houses. Example:

canaries, dogs, hamsters, ...

Wild animals live in the wild. They can live on land (forests,

deserts, jungle, ...), in water (seas, rivers or lakes) or in the air.

They do not need people to get food.

23. Write all the animals you can remember. Then circle:

DOSMESTIC ANIMALS WILD ANIMALS

Circle with a green pencil, the animals that live on land.

Circle with a blue pencil, the animals that live in water.

Circle with a yellow pencil, the animals that live in the air.
