the experiment, present your
output.

12. DISCUSSIONS
Which pair of materials can be
distinguished/identified after
mixing/combining them?
How about the pair of materials
that cannot be distinguished/identified
after mixing them?
Which mixture looked the same
throughout?

13. Is there a change in the property of
the solid materials in the mixture?
What happens to the solid materials
when mixed with other solid materials?
Can you describe the physical state
of each solid material before you mix
with other solid?

14. Directions: Read the situation and write your answer
in the table below.
Situation:
Your mother asks you the food that she will cook for
your birthday party.
What are these foods?
Give three examples.
What are the solid materials combined in these
foods?
What changes happen when a solid material is
mixed with other solid material?

15. List of

16. A. Directions: From the materials below, choose five (5)
pairs of solid materials that can be distinguished and five
(5) pairs of solid materials that cannot be distinguished.
Write your answer in the proper column.

17. Your parents hired a mason to put
a concrete fence in front of your
house. You see that he combines
the gravel and sand but still you
can identify them. What is the
reason why you can still identify
the materials even if he mixes
them?

18. You and your sister bake a cake for
your mom’s birthday. You mix the
flour and baking soda. You notice
that they mix completely and you
cannot identify the materials you
combine. What is the reason why
you can no longer identify each
material?

19. What changes happened to solid materials
when mixed with other solid materials?
• A mixture is formed when two or more
materials are combined.
• Some solid materials can be easily
distinguished when mixed with other solid
materials.
• While some solid materials cannot be
distinguished from each other.
The properties of each solid material like their
size, shape and color do not change after

20. Directions: Look at the pictures. Identify the
changes in the properties of the solid materials
when combined/mixed.
