Today in Social Sciences at the beginning of the class some of us have asked Paqui about her foot and she has said to us: "I am"
Then Paqui has said to us that she has left some homework for us on Monday but the guardia teacher hasn't given anything to us.
Later Alejandro has read about the demographic revolution and some of the causes were less wars, hygiene and medicine improved, people were better fed, reduction of mortality rates, a strong population growth and this caused a high demand for all kind of products.
Paqui has explained us the origin of vaccines that consists of taking the liquid of a bubo and this liquid was introduced in some children and these children become inmunes.This vaccine was discovered by Edward Jenner.
Then Paqui has a shown us a graphic the birth and mortality rates and we have been talking about the life expentacy and Paqui has said us that the life expectancy of Spain is about 84 years.
After that Mª Luz has read about agricultural revolution that consists of innovations to produce more, some of them were:
- Many communal lands were enclosed, to explain this Paqui has used Rebeca and Silvia
- Introduction of the Norfolk four-field system crop rotation that was a system that didn't leave any part fallow.Every year the position of the crops change, and rotate. In one part they cultivated clover in other wheat, in other barley and in the other turnips.
- Selective breeding
All these changes led to an increase of production and a surplus of farmers.
Some new words that we have learned today have been:
-smallpox that means viruela
-bubo that means ampolla
-enclosure that means cercamiento
-graze that means pastar
-manure that means estiercol
-straw that means paja
-flour that means harina
-iron plough that means arado de hierro
-seed drill that means sembradora mecánica
-thresing machine that means trilladora
-clover that means trébol
-turnip that means nabo
-barley that means cebada
-milkmade that means lechera
-antibody that means anticuerpo
Finally a fire alarm has rung and we have to go out of the high school because it was a fire drill.
That was all for today bye see you tomorrow
