2. is anything that occupies
space and has mass.
All the materials around us
are made of matter.
3. 1. Matter has weight and mass
2. Matter occupies space
3. No two objects or matter can
occupy the same space at
the
same time.
4. WEIGHT is the pull of gravity
in matter.
When you weigh an object,
you are really measuring the
pull of gravity on that object.
Gravity controls the weight of
an object.
5. Mass refers to the amount of
matter an object contains.
It is not affected by the gravity.
The mass of an object is
constant.
The mass of an object is
reflected by its weight. The more
mass an object has, the greater
is its weight.
6. Matter takes up space, therefore, it
has volume.
It has length, width, and thickness.
The volume of a regular object like a
block of wood is obtained by
multiplying its length, width, and
thickness. Volume is expressed in
units called cubic centimeter and
cubic meter.
7. Water displacement method is
used to determine the volume of
irregular solids like a small
pieces of stone by measuring
the volume of water it displaces.
The most commonly used units
to express the volume of liquids
are the liter (l) and milliliter
(ml).
9. The molecules in solids move
very slowly and are very close
together.
Solids have definite shape
and volume.
Can you give an examples of
solids.
10. 1. HARDNESS- is the property of solid
matter to resist scratching or abrasion.
(ex. Diamond)
2. MALLEABILITY- is the ability of
materials to be pressed, hammered, or
rolled into various shapes and sizes
without breaking. (ex. Gold)
3. BRITTLENESS- is the tendency of a
material to be easily broken into
pieces. (ex. Glass)
11. 4. ELASTICITY- is the property of
solid materials to be stretched
when pressure is applied on
them. (ex. Rubber band)
5. STRENGTH- metals are used to
constructs buildings, bridges, and
roads because they are very
strong. (ex. Iron and steel)
12. Compared to molecules in solids,
the molecules in liquids are
farther apart from each other.
The force of attraction among the
molecules is weak, so they
always move, roll, slide, or bump
each other.
Liquid take the shape of their
13. Liquids have definite volume but do
not have definite shape.
Liquids expands when heated and
contracts when cooled.
Liquids may dissolve some solids.
Viscosity- is the resistance of a liquid
to flow.
(ex. Condensed milk)
14. In a gas, the molecules are
farther apart compared to those
of liquids.
The molecules bounce off and
move in every direction.
The force of attraction between
the molecules is too weak to hold
them close. (give examples of
15. 1. If a rectangular box has the following
dimensions: length is 4cm, width is 2cm and
thickness is 2cm, what is the volume of the
box?
2. It refers to the amount of matter an object
contains and remain constant.
3. -5. Identify the given illustrations if it shows a
molecules of SOLID, LIQUID, and GAS.
