Materials Materials

Everything is made from some sort of Everything is made from some sort of ‘material’‘material’

Materials are made up of lots and lots of Materials are made up of lots and lots of tiny pieces tiny pieces

These tiny pieces are known as particlesThese tiny pieces are known as particles Solids, liquids and gases are all made of Solids, liquids and gases are all made of

lots of particles lots of particles

Properties Properties

The property of a material tells us The property of a material tells us something about what it is like…something about what it is like…

Materials may be hard, soft, shiny, roughMaterials may be hard, soft, shiny, rough

Solids Solids

A solid is something that we can hold on A solid is something that we can hold on toto

A solid keeps its shape, unless we cut it A solid keeps its shape, unless we cut it or shape it ourselves or shape it ourselves

In a solid, all of the particles are packed In a solid, all of the particles are packed together very tightlytogether very tightly

Liquids Liquids are runnyLiquids are runny They can be poured They can be poured The particles are less tightlyThe particles are less tightlypacked, so they can move about packed, so they can move about If poured from one containerIf poured from one containerto another, they will take the to another, they will take the shape of their new containershape of their new container

Gases Gases

The particles in gases have lots of room The particles in gases have lots of room to move to move

Gases are all around us Gases are all around us They spread into all of the empty places They spread into all of the empty places

they can they can Most are invisible Most are invisible

An example – water An example – water

Water can be a solid, a liquid or Water can be a solid, a liquid or a gasa gas

When it is cold it is solid – ICE When it is cold it is solid – ICE When it is at room temperature it When it is at room temperature it
