MATTER
a.    Properties:
·         Volume: is the space that an object takes up. We measure volume in litres.
·         Mass: is the amount of matter that exists in an object. We measure mass in kilograms.
b.    Types
·         Pure substance: only one compound.
·         Mixture: matter is made up of two or more substances. Homogeneous mixture ( we cannot see the different ingredients) or heterogeneous mixture (we can see de different compounds)
MATTER and ITS CHANGES
There are three states in matter: solid, liquid and gas. Matter changes or can transforms into different matter.
a.    Physical change: the shape or form change (a stone into pieces)
b.    Chemical change: new matter is formed (when wood is born)
