Social Science test Unit 3

Our Unit 3 test will be on Tuesday. You need to study pages 32-38. You should be able to explain the concepts in the book, the words in pink or purple letters, things like "brain drain", "rural exodus", etc.  Also, you should understand and be able to answer questions like the ones from the book that we have corrected in class.

 The students from class 5ºB should bring their Social Science books and notebooks on Monday to work on after the trip to MAPFRE.

Artist or engineer?

Here is an advertisement that features Theo Jansen, the sculptor we are going to see.




He says:

"My name is Theo Jansen.   I’m a kinetic sculptor. My sculptures are made of very light materials, and they are powered by the wind. Part of me is an engineer who wants to map the progress of mobility. Another part is an artist who wants to sculpt the air that surrounds us and give it shape. And always I strive to push the boundaries of what we know, and what seems possible to us at this moment in time. The walls between art and engineering exist only in our minds."

Spanish architect Santiago Calatrava designs bridges and other structures in an artistic way.  This bridge in Calgary, Canada, was designed by him. First it was called the Calatrava bridge, but then the name was changed to the Peace Bridge. Can you recognize any of the machines in the beginning? Diggers, bulldozers, cranes...

He has also designed bridges in Bilbao:




Seville:




and this city of Arts and Sciences, which was built in the bed of the River Turia in Valencia.



So, are they artists or engineers? Or, perhaps we can say that they are both!

Upcoming tests

The upcoming tests will be:

Tuesday, 1 December: Unit 3 Social Science.

For this test you do not have to study pages 40-41 about Europe's population. We will work on that topic with some different activities after the exam.

Thursday, 3 December: Unit 3 English Test.

Later I will tell you what you have to study for this.

Monday, 9 December: Natural Science "Heat and Light."

Other upcoming assignments:

--For Wednesday: The Natural Science notebook page about Conduction, Radiation, and Convection. Some of you have shown it to me already-- they look good! 

--After you work with Yvonne on your writing from the workbook, you have to make the corrections and copy it into your notebook. This is for Friday (5ºA) and Monday (5ºB).

Value scales

Watch this video about how to use line to create different values.  The squares with the highest density have the darkest value!




We can use value to create the illusion of 3D.





When something is in 3D, we say it has form.

The ones on the top have only shape. The ones on the bottom have form.

Population growth and density

2011 Census Spain:  pop. 47,190,494

Birth rate: 472,000

Mortality rate: 388,000

Immigrants: 457,000

Emigrants: 580,000

How many people died (per 1000)?

How many people left Spain to live in another country?

How many people came to Spain from another country?

How many babies were born (per 1000)?

Natural growth = birth rate- mortality rate

2011 census:

Birth rate: 472,000

Mortality rate: 388,000

The birthrate is higher, so there was positive natural growth.

But, we must also look at immigration and emigration to know if the total population increased or decreased.

How is the population distributed?

Questions:
Which areas are most/least populated?  Why?

How do we calculate population density?

What is rural exodus?

Fun with convection currents!

Watch this experiment:




Warm water rises, cold water sinks.
Warm air rises, cold air sinks.

This is called CONVECTION.

Watch some convection currents in action:




One more experiment!

Heat transfer

Heat Energy can be transferred from one object to another in different ways.

When two objects are in contact, thermal energy is transferred from the hotter object to the colder object.  This is called CONDUCTION. The molecules in the hotter object are moving faster, and they transfer their energy to the molecules in the colder object.

But, what is a molecule?

Molecules are the smallest part of any substance. They are made up of two or more atoms linked together.  Here is a water molecule. It has two atoms of Hydrogen and one atom of Oxygen.

Thermal energy travels through a gas or liquid by CONVECTION.

Thermal energy can be transferred through space by electromagnetic waves. This is called RADIATION.
