MATTER DEFINITION: Matter is any substance that has mass and occupies space.

MATTER COMPOSITION: All physical objects are composed of matter, in the form of atoms, which are the smallest part of such substance.

MATTER PROPERTIES: The matter has got properties we can measure: mass and volume.

MASS: Mass is how much matter something has. It is not the weight of an object.
Mass is how much space something takes up. Weight is how heavy something is.

UNIT OF MASS: We use a scale to measure mass and its basic unit is the gram (g). The most used unit is the kilogram (1.000 g).

VOLUME: The volume of an object is a measure of the amount of space occupied by that object. When we listen to the word "volume", we must think of a 3 dimensional object, it means that it must have length, width and height, but all physical objects occupy a volume, even if some are so thin that they appear to be two-dimensional, like a sheet of paper.

UNIT OF VOLUME: The unit of volume is the cubic meter (m3), though we can also use other units as liter (for drinks), mililiter (for medicines) and so on.

MATERIAL: It is the physical substance objects are formed of. And material is what we use to make things. Some material are formed by only one substance, but most are formed by a mixture of different substances, for instance, oxygen is a substance, but air is a mixture.

KIND OF MATERIALS: There are raw materials and artificial materials:
- RAW MATERIALS are materials before we process them - change them into something different. We can find them in Nature:
* Animal: wool or leather
* Vegetable: wood or cotton
* Mineral: iron or silver
- ARTIFICIAL MATERIALS are created by humans using raw materials, for example, glass or plastic.

PROPERTIES OF MATERIALS: Every material has its own characteristics which allow them to differentiate it from another material. Some of these properties are:
- Density
- Conductivity
- Hardness
- Elasticity
- Resistance

DENSITY is a measurement that compares the amount of matter an object has to its volume. The formula to obtain it is: density = mass(g)/volume(cm3)

ART IN CLASS - HALLOWEEN STUFF

Last Halloween, Courtney, our Language Assistant, made a Jack'O Lantern with a pumpkin brought by the teacher Mrs Isabel Arjona. At the same time, we did some crafts: masks, bats, pumpkins mobiles and so on. Please, tick here to see our works.

ART IN CLASS - PLAYING WITH DIFFERENT COLOURS AND FORMS

In this case, we draw either using straight lines or curve lines. We hope you like the results. See the album

ART IN CLASS - PIET MONDRIAN

Our pupils imitate Piet Mondrian's this time.
