7. Learning Targets
7
In this lesson, the learners will do the following:
● Define matter.
● Recognize that solid objects have fixed shape, have
volume, mass, color, texture, and cannot flow.
● Give examples of solid objects found at home and in
school.
● Identify solid objects based on their observable
properties.
13. 13
The world is made up of matter. The air we breathe, the
home we live in, and the food we eat are forms of matter.
14. 14
The water you drink and the clothes you wear are
forms of matter.
15. Matter can be identified by its properties. Property is the
trait that belongs to a certain individual or thing.
15
A ball is round.
You use a smooth mirror
to see your reflection.
You sit on a
solid object.
16. 16
Solids
Matter can exist as a solid,
a liquid, or a gas. Solids have
definite shapes.Their particles
are very close together.
17. 17
Solids
The volume of an object is the
space occupied by the material.
A solid has a fixed volume.
18. 18
A book will remain rectangular,
whether on a table or inside a bag.
Solids
Solids retain their shapes.
19. 19
Green mangoes are unripe while yellow mangoes are ripe.
Solids
The color of the mango tells if the fruit is ripe or unripe.
21. Mass is the amount of matter in a material. As the
object’s mass increases, its weight increases.
21
As the amount of an object’s mass increases, its weight increases.
22. Solid Objects at Home
There are many solids around you. Can you identify the
solid materials inside your home?

23. 23
Solid Objects in School
There are many solids in school. Can you identify the
solid materials in school?
25. Meet Matigas. Your solid superhero.
Help him in completing his
adventure by bringing the
required solid materials.
The first pupil to bring the item
wins a hero point.

Exploring Your Home
Procedure
1. Select a room or spot in your home.
1. Find 5 solid objects.
1. Describe the properties of these objects.
38. 38
4. Write your observation in the table below.
Object
Size
(big or
small)
Shape Color
Texture
(rough or
smooth;
hard or
soft)
Weight
(light or
heavy)
43. Remember
43
● Matter is defined as anything that
occupies space and has mass.
● The particles of solids are very
close together, resulting in solids
having a definite shape and
volume. They also have mass,
color, texture, and cannot flow.
44. Remember
44
● All matter can be identified by their
different characteristics and properties.
○ The volume of an object is the space
occupied or filled by the matter.
○ Solids have many different shapes.
Solids retain their shapes, whatever
form they may have.
45. Remember
45
● All matter can be identified by their
different characteristics and
properties.
○ Color is an observable property
of solids.
○ Texture describes how an object
feels when you touch it.
46. Remember
46
○ Mass is the amount of matter found
in objects or materials. As the
amount of an object’s mass
increases, its weight also increases.
Weight is how the force of gravity
acts upon the object’s mass.
