Matter is composed of atoms and has properties including color, odor, taste, volume, density, mass, hardness, and solubility. There are two main types of matter: pure substances, which are made of only one type of atom, and mixtures, which are made of two or more substances. Mixtures can be either homogeneous, where the substances cannot be seen individually, or heterogeneous, where individual substances are visible. Different methods can be used to separate substances in mixtures, including filtration, evaporation, and sieving.

2. Matter and its properties
Matter -> made out of atoms (tiny particles).
Properties -> Colour, Odour and Taste.
Volume -> Describes how matter occupies.
Density –> Is the amount of matter
in a volume.
Mass -> Is the amount of matter
in a object.
Hardness -> Is the scratch-resistance of a solid.
Solubility -> Is the ability of a substance to
disolve in other substance.
Thermal Conductivity Ability to conduct or
transfer heat.

3. Wath types of matter are there?
Types:
Pure substance -> Is made up of one type of matter (Silver).
Mixtures -> Made up of two or more substances.
Homogenous -> Cannot see individual substances (Air, sea water).
Heterogenous -> We can see individual substances (Sand, salad).

4. There are different methods to separate the substances.
Filtration -> Using a filter.
Evaporation -> The liquid evaporates and leaves only
the solids wich crystallise and form salt crystals.
Sieving -> We use a sieve to separate solids of different
sizes, such as pebbles from sand.
