3. 1. Matter has weight and
mass
2. Matter occupies space
3. No two objects or matter
can
occupy the same space at
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
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.
