How the brain works



The brain is the most fascinating part of the human body. Not much to look at, it resembles a spongy mass of tissue, feels like toffe and weighs roughly four taps of butter. A brain is actually made up of mostly water and about ten per cent fats. Well, our brain only makes up approximately the two per cent of the entire body weight. It uses a massive twenty per cent of the body's energy.

The brain's basic building blocks are known as neurons and we have around one hundred billion of these, each with between one thousand to ten thousand conexions to other neurons, creating neuropathways or roads within the brain. There are literally trillions of neuroconexions within the brain. Similar to a city's electrical power grid, information is passed along these roads through a series of chemical messages and electrical impulses.

As all of this activity takes place, our brain generates between ten to twenty five watts of power, enough to par a lightbulb. Over the course of one day, your brain generates more electrical impulses from faring neurons than all of the telephones in the world. So really, your brain isn't just a spongy mass of tissue, it's your most complex organ, a power station that connects you every thought, movement or feeling. And it's faring right now.


Digestion


Our body needs food to provide it with energy, vitamins, and minerals. However, in order use food, we must first break it down into substances that the various organs and cells in our body can use. This is the job of our digestive system.

Respiration




The human respiratory system contains the organs that allow us to get the oxygen we need and to remove the waste carbon dioxide we don't need. It contains these parts:

Circulatory System

Made up of the heart, blood and blood vessels, the circulatory system is your body’s delivery system. Blood moving from the heart, delivers oxygen and nutrients to every part of the body. On the return trip, the blood picks up waste products so that your body can get rid of them.


Excretory System

As your body performs the many functions that it needs in order to keep itself alive, it produces wastes. These wastes are chemicals that are toxic and that if left alone would seriously hurt or even kill you.


Adjectives


An adjective is a word that describes a Noun.

A large dog.
Clear water.
The big house.
Clean floor.

The Water Cycle

   
The earth has a limited amount of water.  That water keeps going around and around and around and around and ... in what we call the "Water Cycle".

From Prehistory to Old Age

This is a timeline of the  Prehistory and History. When does History begin?



Check this video that introduces human prehistory.




PALAEOLITHIC AGE


In the caves of  Atapuerca (Burgos) we can see the fossils of the first human beings that lived in Europe one million years ago. 
 
In the Palaeolithic Age human beings survived by eating the animals that they hunted or fished and the fruits and vegetables that they gathered. When there wasn´t enough food they migrated to another area, they were nomads. 


People lived in tribes, groups of about thirty members. They lived outdoors or in caves or huts they built with sticks and animal skins.


They made tools from stone or animal bones. 





 NEOLITHIC AGE


In the Neolithic Age human beings cultivated plants and domesticated animals, to take care of them they became sedentary. They lived in villages. 

They created polished stone tools more elaborated than Palaeolithic tools. They also learnt to make textiles on simple looms and  ceramic containers for cooking and storing  food.

THE METAL AGES 


The Metal Ages began around 6,000 years ago, when the human beings learnt how to make objects from metal. Cooper was the first metal they used, then bronze and finally iron. 


The cities choose leaders to organise and people specialise even more than in Neolithic: Warriors defended the city, farmers worked the land merchants bought and sold products. Wheel and plough were invented.



 THE FIRST ARTISTS


The first artists appeared in the Palaeolithic Age. They painted animals on the walls and ceilings of the caves. They mixed minerals with animal fat to make different colors. If you click on HERE you´ll see one of the most well known caves in the world: Lascaux (France).

In Cantabria (Spain), we have the non less important cave of 




 ROMANS IN HISPANIA 


In the year 218 B.C. the Romans landed in Emporion, defeated the Carthaginians and started the conquest of the Iberian Peninsula.  But this conquest took them a long time, it finished in 19 B.C. under the Emperor Augustus. 

To organise Hispania they divided the territory into provinces, with a governor to keep the order and collect taxes. Roman law was enforced and  Latin became the official language. Christianism was  the official religion after the year 380 A.D. Society was the same as in the rest of the empire, with free men that could participate in the government and own property  and slaves that didn´t have any rights. 



The Romas built cities with two main streets that crosses each other: Cardo and Decumanus. At the intersection of these streets they built the forum, a square with the main buildings of the city. They built temples, markets, theatres,  circuses, thermal baths, roads, bridges, and aqueducts. The Romans decorated the walls with paintings and mosaics.
