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!!

Challenge yourself describing leaves!

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.

The sense of taste.

We taste with our tongue to find out the flavour of food. The sense of smell is also important to taste.

The taste buds contain the recptors for taste.



Taste buds are located in the tongue according to the flavor they can distinguish:

-salty and sweet: near the front.
-sour: at both sides.
-bitter: at the back.

The sense of hearing.

We use our ears to hear things.
Some sounds are nice,such as music, and others are loud and noisy; for instance, someone shouting .
The ear: sounds enter the outer ear and travel to the eardrum along the ear canal.



Three small bones, the hammer, anvil and stirrup, make sounds louder.



The sound goes to the brain through the auditory nerve.

The sense of sight.

We use our eyes to see and to identify size, shape, colour and movement.
The eye: we look at an object and the image of the object gets into the pupil. Then, the optic nerve sends what we see to the brain.

Sense it!

The sense of sight.

We can see with our eyes.

We see and identify:

-Shape.

-Colour.

-Size.

-Movement.

The sense of hearing.

We can hear with our ears.

1. Parts of the ear:

2. We can hear noise and sounds:

• Noises are unpleasant.
• Sounds are nice.

              Noises and sounds can be loud or low.

The sense of taste.

We can taste with our tongue.

1. When we taste we distinguish 4 flavors:

- Salty

-Sweet

-Sour

- Bitter

2. We have taste buds in our tongue:

Taste buds are arranged in our tongue in this way:

The sense of smell helps the sense of taste to identify the food.

The sense of smell.

We can smell with our nose.

The nose has 2 external cavities called the nostrils. 

They take the air into the nose.

Sense of touch

We can touch/feel with our skin.

We feel temperature and texture.

1. Temperature: hot or cold.
2.  Texture:

• Rough or smooth.
• Hard or soft.
