Rural Vs. Urban life.

Do you live in a rural or in an urban area? Answer this question as a comment to this post and you will get a lollipop!




Rural and Urban Life.

Urban life: Cities and towns:

  1. There are many different kinds of buildings.
  2. There are different urban transport systems: underground trains ( Ex. London´s Tube, NY´s Subway or Madrid´s Metro) or bus lines.
  3. There's a complex system of streets, avenues, squares and roads to move around a city.

Rural life: villages and hamlets.
  1. There aren't so many buildings and they are small.
  2. The public means of transport are used to go to other towns, cities or villages.
  3. Streets are narrow because the traffic is not a state.
  4. We can find farms in the villages or around them since they are on the countryside.

Can you place on the map the South China Sea, the Caribbean Sea, and the Mediterranean Sea?

Students leaving comments with underwater life video links will get a lollipop, come on fourth-graders!

Rivers.

A river is a stream of water.


A tributary river flows into another river.


Rivers flow along a channel.
The bottom of the river is the bed.
The sides of the channel are the banks.


Cliffs and plateaus

Cliffs are rock or soil steep walls.




A plateau is the plain where the houses are. 







A plateau is a plain on a higher position.


Glaciers

Glaciers are huge areas of moving ice.


Glaciers move downwards because of Gravitation.

Hills, mountains and valleys.

Mountains are high and have pointed tops. On the other hand, hills are not so high and have rounded tops.





Ex: The green ones are hills since they are not so high as the ones on the background, those are mountains: they are pointed topped.








Valleys are low areas among mountains or hills.







Can you see those mountains
The valley is between them.

The circulatory system.



The heart and the blood vessels form the circulatory system.

The circulatory system carries blood around our body.






Types of blood vessels.

There are three types of blood vessels:
  1. Arteries: they carry blood full of nutrients and oxygen.
  2. Capillaries: they are small ones because they get to every part of our body.
  3. Veins: they carry blood poor in oxygen and nutrients.
  4. Types of Blood Vessels

The respiratory system


Inhalation: To breathe in.

Exhalation: To breathe out.









Inhalation:

  1. Our nose cleans and warms up the air. 
  2. The air passes through the larynx and the windpipe
  3. Then the windpipe is divided into the two bronchial tubes
  4. Finally the air goes into the lungs.

Exhalation:

The air goes the opposite direction from the lungs to the nose/mouth through the bronchial tubes, the windpipe and the larynx.
