Unit 5: Diet, digestion and excretion.

Food contains the nutrients we need to live and grow.
There are five types of nutrients:
- carbohydrates (potatoes, bread, cereals, pasta, pulses and rice)- they give us energy
- fats (oil, butter, chorizo, cheese and nuts)- they build a store of extra energy for when we need it.
- proteins (meat, fish, eggs, nuts and milk products)- they help us grow
- vitamins and minerals (fruit and vegetables)- they help us to stay healthy

More than half of our body is water so we need to drink between 6 to 8 glasses everyday and, when we do exercise, we need to drink more.

Our diet is what we eat, and it can be healthy or unhealthy.

To be healthy we need to eat:

- a variety of food

- more of some things and less of others.

Red Group - The food on this level is unhealthy because it contains lots of salt, sugar and fats. Don´t eat it everyday, only on special occasions.

Yellow Group - The food on this level is essential but in small quantities. Eat a little of it everyday because if you eat too much it can make you overweight.

Green Group - The food on these levels are essential for good health. Eat some everyday.

What else can we do to be healthy?

To be healthy we should...

- ... rest - we should go to bed early and sleep 10 to 11 hours everyday

- ... do exercise - we should do some exercise everyday

- ... have a good hygiene - we should have a shower everyday, brush your teeth after meals and wash your hands before you eat and after you use the toilet.

- ... prevent diseases - we should cover our mouth when we cough or sneeze, visit the doctor regularly.

- ... use free time wisely - we should read, learn new things and spend time with your family and friends instead of watch TV or play videogames.

OUR DIGESTIVE SYSTEM

Our digestive system helps us to get the nutrients we need from food.

1. The mouth - it has teeth that break the food into small pieces and a tongue that mixes the food with saliva so it´s easy to swallow.

2. The oesophagus - it is a long tube through which the food goes down to the stomach.

3. The stomach - it is like a bag. The food stays here for about three hours. Gastric juices turn the food into a thick liquid that leaves the stomach and goes to the small intestine.

4. The small intestine - it is a very long thin tube. Here, the nutrients pass from the thick liquid to the blood.

5. The large intestine - it is a wide tube connected to the anus. What our body doesn´t need goes along here and out through the anus when we go to the toilet.

OUR EXCRETORY SYSTEM

Our excretory system helps our bodies to get rid of excess water and waste products.

1. The kidneys - The blood goes to the kidneys and they remove excess water and waste products turning them into urine.

2. The ureters - they are long tubes where the urine goes down to the bladder.

3. The bladder - it is like a bag where the urine is collected. When it is full, it sends messages to our brain to go to the toilet.

4. The urethra - it is a short tube through which the urine goes down and leaves our body. 

Unit 4: Spain

Spain is in the south of Europe and it is part of the Iberian Peninsula.
It also has two archipelagos: the Canary Islands and the Balearic Islands.

Spain has borders with:
- France and Andorra in the north
- Portugal in the west

There are also seas and an ocean around Spain´s coast:
- in the north the Cantabrian Sea
- in the west and south west the Atlantic Ocean
- in the south and east the Mediterranean Sea

Spain is divided into autonomous communities. There are 17 autonomous communities and 2 autonomous cities: Ceuta and Melilla.
Each autonomous community has:
- a capital
- a flag
- a coat of arms
- an anthem

SPAIN´S RELIEF

Spain has different mountain ranges and a big plateau (an area of high flat land) in the centre called Meseta

SPAIN´S RIVERS

Spain´s most important rivers are: the Miño, the Duero, the Ebro, the Tajo, the Guadiana, the Guadalquivir, the Júcar and the Segura.

MIÑO

The source of the Miño is in Sierra de Meira and it flows into the Atlantic Ocean.

The Sil is its main tributary.

DUERO

The source of the Duero is in Picos de Urbión and it flows into the Atlantic Ocean.

The Pisuerga and the Esla are its main tributaries.

EBRO

The source of the Ebro is in Fontibre spring, in Cantabria, and it flows into the Mediterranean Sea.

The Zácara is its main tributary.

GUADALQUIVIR

The source of the Guadalquivir is in Sierra de Cazorla and it flows into the Atlantic Ocean.

The Genil and the Gadajoz are its main tributaries.

The source of a river is the place where it begins.

The mouth of a river is the place where it ends and flows into the sea, ocean, lake or another river.

Tributaries are smaller rivers that flow into another rivers.

Natural - Unit 4: Our Systems

1. OUR SENSES
We have five senses and each sense has an organ.

1. Sight - The organs of sight are the eyes and we use them to identify colour, size, shape and     distance.
2. Taste - The organ of taste is the tongue and we use it to identify different flavours.
3. Touch - The organ of touch is the skin and we use it to identify if something is hot or cold, hard       or soft, smooth or rough.
4. Hearing - The organs of hearing are the ears and we use them to identify loud, quite, high and         low sounds.
5. Smell - The organ of smell is the nose and we use it to identify different smells.

Our sense work together with our nervous system.

2. OUR NERVOUS SYSTEM
The nervous system is made up of the brain, the spinal cord and the nerves.

1. Brain - The brain controls everything that happens in our bodies.
2. Spinal cord - The spinal cord connects most nerves of our body to the brain.
3. Nerves - The nerves carry messages to the brain.

3. OUR LOCOMOTOR SYSTEM
Our locomotor system makes our body move and it is made up of bones, joints and muscles.
It uses nutrients from food and oxygen to work.
We use our locomotor system to move, eat and speak.

1. Bones - We have 206 bones and they are hard and rigid. Bones make up the skeleton and they         support the body and protect vital organs.

2. Joints - Joints are where two or more bones meet. At the joints, tendons attach muscles to the         bones. They allow us to bend.

3. Muscles - We have 600 muscles and they are elastic and flexible. We can move some of them (biceps), and other muscles move automatically (heart).


4. OUR CIRCULATORY SYSTEM
Our circulatory system carries nutrients and oxygen around the body. It is made up of the heart, the blood and the blood vessels.

1. The heart - It is a muscle the size of your fist and it´s in the middle of the chest. It works day and night to pump blood to every part of the body.

2. The blood - It is a red liquid that goes around the body. It travels in blood vessels.

3. The blood vessels - They are thin tubes through which the blood circulates.

5. OUR RESPIRATORY SYSTEM
When we breath in, oxygen enters our blood through the respiratory system.
When we breath out, the carbon dioxide leaves our body.
The respiratory system is made up of the nostrils, the windpipe, the bronchi and the lungs.

1. The nostrils - The nose has two holes called nostrils where the air enters our body.

2. The windpipe - It is a tube that carries air to the lungs.

3. Bronchi - Two tubes of the windpipe that carry the air to the lungs.

4. The lungs - They are two sacks made up lots of little sacks where the air goes in.

The process 
1. When we breath in, oxygen enters through the nostrils.
2. Next, it passes through the windpipe and goes down the bronchi into the lungs.
3. Then, the oxygen passes from the air into the blood and the carbon dioxide passes from the blood into the air.
4. Finally, the carbon dioxide leaves our body when we breath out.

6. OUR REPRODUCTIVE SYSTEM

Our reproductive system allows us to have babies.

Men and women have different reproductive systems.

Social - Unit 3: Europe

Europe is the second smallest continent in the world and it is in the Northern Hemisphere.
- to the north of Europe there is the Arctic Ocean
- to the south there is the Mediterranean Sea and the Black Sea
- to the west there is the Atlantic Ocean
- and to the east there is Asia

On relief maps of Europe we can see:

1. MOUNTAIN RANGES
    Europe´s most important mountain ranges are:

    - The Ural Mountains
      They are in Russia and they form a natural border between Europe and Asia.
      The Ural Mountains are Europe´s longest mountain range.
   - The Alps
     They are the highest mountain range in Europe.
     The Alps are in seven different European countries, such as France, Italy, Switzerland and                    Austria.
     The highest mountain in the Alps is Mont Blanc.
   - The Scandinavian Mountains
     They are on a peninsula in the north of Europe and form a natural border between Norway and            Sweden.
     They´re on of the oldest mountain ranges in the world.


2. RIVERS
    Europe´s most important rivers are:

   - The Volga
      It is in Russia and it´s the longest river in Europe. It flows into the Caspian Sea.
   - The Danube
      It is the second longest river in Europe and flows into the Black Sea.
   - The Rhine
      It starts in the Alps and it flows into the North Sea.


On political maps of Europe we can see many countries and cities. There are 47 different countries in Europe and each one has its own traditions and, many, their own language.

We are going to study some of them:

Natural - Unit 3: Plants

Plants are living things: they are born, grow, reproduce and die.
Plants need water, nutrients and minerals (from the soil), air and sunlight to live. They make their own food.
Plants can´t move around but they can move one or more of their parts.

Parts of a plant

All plants have roots, stems and leaves and these have different functions:

1. Roots - They fix the plant in the soil and get water from it.
2. Stem - It holds the plant up and the food pass through it to grow.
3. Leaves - The plant makes its food in them.

Plant reproduction

Some plants have flowers. Their reproductive organs are inside the flower.
Flowers have different parts:

The corolla is made of petals. Petals are different colours to attract insects.
The stamens are the male reproductive organs. They have pollen at the top.
The pistil is the female reproductive organ. It has ovules inside.
The calyx is made of sepals. Sepals are green and protect the flower.

The reproductive process or pollination process.

First, an insect takes pollen form a stamen to a pistil.
Then, inside the pistil, the pollen joins an ovule to make a seed.
Next, the petals fall off the flower and the pistil grows around the seed into a fruit.
Finally, the fruit falls on the ground and the seed grows into a new plant.

Plant nutrition

Process = Photosynthesis

First, roots absorb minerals and water from the soil.
Then, water and minerals pass through the stem to the leaves.
Next, leaves absorb sunlight and carbon dioxide from the air.
Finally, when plants make food, they make oxygen too to return it to the air. That´s good because animals need oxygen to live!

Photosynthesis = minerals + water + sunlight + carbon dioxide = food + oxygen

Types of plants

Tree

If a plant has a trunk, it is a tree. The branches on a tree grow high above the ground. Trees grow slowly.

Bush

If a plant has a woody stem, it is a bush. The branches on a bush grow near the ground.

Grass

If a plant has a flexible, green stem, it is a grass. Gasses are usually short and grow quickly.

We can also classify plants by their leaves:

- Evergreen - they always have leaves

- Deciduous - they lose their leaves in autumn and grow new leaves in spring.

In what ways do we use plants?

We use plants to:

- make clothes (we get thread from cotton plants)
- make furniture (we use wood from tree trunks)
- make paper and card (from wood)
- eat (we eat fruit and vegetables). We eat roots (ex. carrots), stems ex. asparagus), leaves (ex. lettuce) and flowers (ex. cauliflower)
- make flour (we use flour to make bread, pasta and biscuits)
- make perfumes, soap and cosmetics
- make some medicines
