The primary sector.

The primary sector takes raw materials from nature. Economical activities included in the primary sector:

• Agriculture and farming:

                      - Livestock: To breed and take care of animals.

                      - Crops: To grow crops.

• Fishing: there are two kinds of fishing:

              - Coastal fishing: Fishermen work near the coast:

 

               - Deep-sea fishing: Fishermen work far away from the coast:

                        

• Mining: It is the extraction of minerals from the Earth. It includes oil and gas.
• Forestry: it uses the resources from the forests, e.g: wood.

Economic sectors.

There are three economic sectors:

1. The primary sector: it gets raw materials.
2. The secondary sector: it manufactures products. It is based on industry (factories) and craft. Engineering is part of this sector.
3. The tertiary sector: it is the service sector.

Parts of a city or a town.

A neighbourhood is a localised area in a city or a town.

                    This is New York City neighbourhood map:

The Old Quarter is the oldest neighbourhood of a city or a town.

New parts of the city: there are parks, shopping centers, offices and appartment buildings.

The outskirts: areas outside the city or the town. There are hospitals, factories, airports or recycling facilities.

Urban and rural life.

Cities are large urban areas where lots of people live.

Urban communities smaller than a city are towns. They haven´t got a cathedral.




A village is smaller than a town. Villages are located in rural areas.


A hamlet is a very small rural kind of place.

What do you eat?

Plants make their own food.

Animals have to eat in order to grow and reproduce.

Some animals eat other animals, they are carnivore animals.



Other animals eat plants, they are herbivore:




We, human beings, are omnivore. We eat both plants and animals.

Enjoy your food hungry omnivore!!

What do you know about bats?

Print, read and colour!

Birds.

Birds are vertebrate and oviparous.













They have a beak and wings.

Finally, most of them can fly:

What a wonderful world!

Have a look and enjoy yourselves!

Remember...

Living things are born, grow, reproduce and die.

We can divide the living things into plants, animals and human beings.

We know a lot about plants after the last unit.

What about animals?

Welcome to unit 3: The animals.

Can you remember what the backbone is?





Can you touch your backbone?

If an amimal has got a backbone it is a vertebrate animal.

The opposite: invertebrate animals haven't got a backbone.

Think about your favourite animal... has it got a backbone? is it vertebrate or invertebrate?

Do you want have a look around an exiciting museum? This is the Oxford University Museum of Natural History.

The alien!

Have fun with this alien!

Another animal classification!

Animals that are born from an egg are oviparous.

Animals that are born from their mother's womb are viviparous. The embryo is developed in the mothe´r's body.

Can you remember The very hungry caterpillar.?

Is the butterfly a viviparous or oviparous animal? And you?

Mammals:

They are vertebrate
The mothers feed their babies with milk.
They have hair (or fur)
Most of them are viviparous.



Can you recognize any other mammal around you?
Look at a mirror! We, human beings, are mammals!

The mammals.

Characteristics of Mammals:

• They are vertebrate


• Most mammals are viviparous.


• They have lungs to breath and get oxygen.


• They have hair, or fur.


• Female mammals produce milk to feed their children.

Fish.

They are vertebrate.



They are aquatic. They live in the water.





They are covered with scales.

Vertebrate animals.

There are five vertebrate animal groups.

-Fish.
-Reptiles.
-Amphibians.
-Birds.
-Mammals.

What kind of vertebrate animal is Michael Phelps? Is he a fish? NOOOO!!!

He is an amazing mammal!

Are they vertebrate or invertebrate?

Remember vertebrate animals have got a backbone.

Invertebrate animals haven't got a backbone.

Are these animals vertebrate or invertebrate?

Three invertebrate animal groups.

There are three invertebrate animal groups.

Insects:

Worms

Arachnids

A new game!!

Do you know everything about vertebrate animals?

Have fun classifying the vertebrate features!!

Reptiles.

They are oviparous.



They are vertebrate.



Their body is covered in scales:

Amphibians.

They are vertebrate.




They are oviparous.



Their main feature is that they metamorphose. This means they change, they have different stages:

Photosynthesis.

Green leaves make the energy the plant needs to live.

Water and minerals come from the soil, through the roots; carbon dioxide from the air and sunlight from the sun,through the leaves.

All these elements are transformed into energy(in the form of glucose or sugar), the food the plants needs to grow and reproduce.

At the end of photosynthesis oxygen is released (liberated, set free).

Have a look at these pictures:

Photosynthesis, the hungry plant.

What do plants do when they are hungry? Can they order a hamburguer?

NOOOOO!!

Can you describe these leaves?

Life cycle of a plant.

The fruits contain the seeds of the plant:










The seed falls in the soil and germinates:



A new plant, its name is seedling, grows after this process:



This new plant grows and has flowers. Insects pollinate these flowers and we will have new fruits.

Have a look around you!

Plants are very different.


Some plants have flowers:



These are almond trees.





Some plants have thin leaves:



This is a palm.





Other plants, such as the fig tree, have broad leaves.

It is important to see if leaves are flat or they are not.

Some plants produce fruits the animals and human beings can eat, see this apple tree loaded with apples:

Parts of a plant.

The main parts of a plant are: roots, stem, leaves and flower.












Roots: they hold the plant in the ground, they also take water and minerals from the soil.

Stem: it carries water and minerals from the roots to the leaves.

Leaves: they use the sunlight energy, carbon dioxide, water and minerals to make the plant's own food.

Flowers: they produce seeds. New plants will grow from the seeds.

The nervous system.

When we see, hear, touch, smell or taste the information goes to the brain.





This information goes to the brain through the spinal cord.




The parts of the nervous system are: the nerves, the spinal cord and the brain.

The sense of smell.

We use our nose to smell things.




The nose: The two external cavities are called nostrils and take the air into the nose. Behind the nostrils we find the nasal cavity.

The sense of touch or feeling.

We use our skin to touch and feel objects.

Nerve sensors in the skin detect the temperature –hot, cold, warm- and texture –rough, smooth- of objects.
