VERTEBRATES AND INVERTEBRATES 17 1. Animal skeletons

Vertebrates are animals with a skeleton.

The skeleton is made up of bones. The bones are joined together to hold the body up. They protect it.

All vertebrates have a spinal column.

2. Vertebrate bodies

Vertebrate bodies have several parts:

The head. The skull protects the head.

The trunk. The spinal column, ribs, shoulders and hips are all in the trunk.

The limbs. The bones are long. Some vertebrates have legs. Others have wings or fins. Some vertebrates, like snakes, have no limbs.

The tail. This is an extension of the spinal column. There are very small vertebrae in the tail.

CONTENT AND LANGUAGE DEVELOPMENT

Vocabulary. Write the following list of vocabulary on the BB and then read aloud the first sentence. The Ss must say which word finishes the sentence correctly. Then do the same with the other sentences.

2. Fish have … (fins)

3. Snakes have … (no limbs)

4. All vertebrates have … (a spinal column) 5. Some vertebrates have … (legs)

6. The tail has very small … (vertebrae)

Vocabulary

head, invertebrate, limbs, spinal column, tail, trunk, vertebrate

Special attention

• Interpreting diagrams of animal skeletons • Understanding that fish are vertebrates

and that most fish have a skeleton made of bones

Hands on

Presentation

• Play and tell Ss that in order

to match the skeletons to the animals, they must look at the silhouette. (fish – a;

duck – b; leopard – c) The skeleton gives

shape to the body.

• Ask the Ss to locate the spinal column in each picture. This is a characteristic of all vertebrates. Ask the Ss: Can you describe

the spinal column? (long and made up of small bones called vertebrae) Where is it? (The spinal column extends from the head to the tail.)

• Play and practise the vocabulary.

Present and with and . Tell Ss

that the diagram shows vertebrate groups. Ask them to write sentences:

Dogs are mammals. Robins are birds. Crocodiles are reptiles …

Ask the Ss: How can we find out about

animals? (Elicit: Observe them.)

• The Ss study an animal, for example

an ant, in its natural habitat. Ss draw a picture and write what the animal was doing.

• Ask Ss to observe a pet. If possible,

take a pet animal to class, such as a turtle or a hamster. Give some observation guidelines: Look at hair,

feathers. Look at how it moves. Look at what the head, eyes … are like.

Special attention

• Understanding that marine

mammals are not fish, although they live in water

• Distinguishing differences between all,

almost all, most, many, some, other …

• Expressing contrast: however

Presentation

• Do the matching activity together

Play .

• Ask the Ss how they know if an

animal is a mammal or not: Is a cow a

mammal? And a sheep? What do they drink when they are babies? (their mother’s milk)

• Ask the Ss: Does a bird or fish drink its

mother’s milk? How do fish and birds eat when they are babies? Can you describe their bodies? The Ss then read and and do the activity.

1. Mammals

Mammals are vertebrates. They are born live. They drink their mother’s milk

when they are babies.

All mammals breathe air.

Most mammals are land animals. However, some mammals, like dolphins, are aquatic.

Most mammals have hair on their bodies. However, aquatic mammals have bare skin.

Almost all mammals walk or swim. However, bats can fly.

2. Birds

Birds are vertebrates. They are born from eggs. They have feathers on their bodies.

All birds breathe air.

Birds have two legs and two wings. All birds have wings. However, not all birds can fly, for example penguins.

Many birds, such as sparrows, live on land. They can fly and walk.

• Other birds, such as ducks, live on land and water. They can fly, swim and walk. cow

Ss to copy them in their notebook. Then Ss listen to and

and circle the correct answer.

1. Mammals are born a) from eggs b) live

2. Most mammals are a) land animals b) aquatic animals

3. Bats can a) swim b) fly

Bird feathers

• Collect different types of feathers and

explain their function: What are

feathers used for? (Feathers are used for flying, to keep birds warm, and to attract mates.) Compare the different

feathers: small, soft, large, pointed.

• Show that the base of the feather is

hollow. Tell Ss that in the past, feathers were used for writing by introducing ink into the hollow part (quill).

M.A. They have feathers on their bodies. They have two legs and two wings.

They breathe air. Many birds live on land. Other birds live on land and water.

Special attention

• Understanding that the bodies of invertebrates are soft, even though they have hard protective coverings

• The difference between a shell and an exoskeleton

• Check comprehension by asking the Ss to complete the sentences with shells or

exoskeletons. Beetles have …

(exoskeletons). Mussels have … (shells).

Ask Ss which sentences are false: Insects

have six legs. All insects have wings. (F) All insects are invertebrates. Insects are born from eggs.

• Look at the insect. Ask Ss: What do you

notice about the insect? How many wings does it have? (two pairs) How many legs? (six) How many antennae? (two)

• Finally, distribute photocopies of the activity on the opposite page and ask Ss to choose the correct word.

• Play and to practise the vocabulary

VERTEBRATES AND INVERTEBRATES 19 1. How invertebrates protect their bodies

Invertebrates have no bones.

Some invertebrates have a protective covering.

Shells are hard and strong.

Exoskeletons can be thick or thin.

Crabs have thick exoskeletons. Beetles have thin exoskeletons.

Some invertebrates, like jellyfish and worms, have no protective covering.

2. Insects

Insects are a kind of invertebrate. An insect has three parts to its body.

The head has a mouth, two eyes and two antennae.

The thorax has wings and legs. Most insects have wings. All insects have six legs.

The abdomen is joined to the thorax.

3. Insect life

Insects are born from eggs. Young insects are called larvae. Some larvae are caterpillars. They have no wings or antennae.

All insects breathe air.

Some insects, like butterflies, are herbivores. Other insects, like dragonflies, are carnivores. Others, like flies, are omnivores.

Insects with wings fly or walk. Insects without wings walk.
