Three states of matter
Solid-rigid materials with definite shape and volume.
Liquid-definite volume independent in each container but has no definite shape.
Gas-has no definite volume and shape.
4
Molecular Structure of Solid
Particles in a solid are tightly packed, usually in a regular pattern. They vibrate (jiggle) but generally do not move from place to place.
5
Molecular Structure of Liquid
Particles in a liquid are close together with no regular arrangement. They vibrate, move about, and slide past each other.
6
Molecular Structure of Gas
Particles in a gas are well separated with no regular arrangement. They vibrate and move freely at high speeds.

Special Properties of Solids
Malleability- the ability of solids to be hammered into thin sheets.
Hardness- the ability to resist physical changes.
Strength- A measure of a material's resistance to failure.
Brittleness-the ability of matter to be broken down into pieces.
9
Properties of Liquids
Have no definite shape.Have definite size and amount.Take the shape of their
containers.Move freely or they have the
ability to flow.
10
Properties of Gases
They are easy to compress, They expand to fill their
containers, and They occupy far more space
than the liquids or solids from which they form.
11
Measuring Matter Matter can be measured.
Measuring devices that are used are the weighing scale, ruler, meter stick and graduated cylinder and tape measure.
12
Good Effects of MatterMatter is everywhere. We can see it in the
kitchen, garden , dining area and many more. Solid objects like books, ball pen and paper are used in the school. Substances such as soy sauce and fish sauce are use to give taste to the foods we
eat.
13
Bad Effects of Matter
If matter is not properly utilized like the knife , it will
cut your hand or finger. Thus, if matter is not place
in it’s right place for example the pesticides,
children may reach it and it will poison them.
14
Safety Measures
Label the containers.Read directions before using.Return things to their proper places.Keep harmful substances and
breakable objects away from children.
Ask the assistance of older people.
