Matter is anything that occupies space and has mass. It has general properties including mass, which is measured in kilograms and grams, and volume, which is measured in liters and milliliters. Matter can also have special properties such as hardness, brittleness, elasticity, and density, which is the ratio of an object's mass to its volume. Forces can move, change the shape of, or break matter. Materials are the substances used to make objects and have properties like thermal conductivity, transparency, and impermeability.

2. 1. MATTER
Matter is anything that occupies
space and has mass.
General
properties
of matter
MASS:
Is the quantity of matter that an
object has.
We measure mass in kilograms
(kg) and grams (g)
VOLUME:
Is the quantity of space that an
object occupies.
We measure volume in litres (l)
and milllileters(ml)

3. 2. SPECIAL PROPERTIES OF MATTER
HARDNESS
Matter is hard when
it`s difficult to scratch.
BRITTLENESS
Matter is brittle when
it breaks easily.
ELASTICITY
Matter is elastic when
it return to its original
shape
DENSITY
Mass
Density =
Volume

4. 3. FORCES
Forces produce different effects. They can move
objects, change their shape or break them.

5. 4. PROPERTIES OF
MATERIALS
Material is the matter we use to make objects.
PROPERTIES
OF
MATERIALS
THERMAL CONDUCTIVITY
- Insulator materials don`t transmit heat.
- Conductor materials transmit heat.
TRANSPARENCY
- Opaque materials don`t let light pass through.
- Transparent materials let light pass through.
IMPERMEABILITY
When a material doesn`t let liquid pass through, it is
impermeable
