COMPONENTS OF
MIXTURES

6. Learning Objectives

Explain the different
methods in separating
components of
mixture;

7. Learning Objectives
Skills:
Demonstrate some
of the methods of
separating
components of
mixture;

8. Learning Objectives

demonstrating those
methods.

9. 2. REVIEW
1. What is a
mixture?

10. A mixture is made
up of more than
one substances
combined
physically.

11. 2. What are
the types of
mixture?

12. TYPES OF MIXTURES:
Homogeneous
and
heterogeneous
mixture

13. 3. Is it possible
to separate the
components of
a mixture?
Why?

14. Yes, it is
because the
substances are
just physically
combined.

15. 4. How can you
separate the
components of a
mixture?

16. ACTIVITY :

17. LET’S DISCUSS THE
DIFFERENT
TECHNIQUES OR
WAYS OF
SEPARATING
MIXTURES

19. With your teammates,
you will be assigned
with a station which
has a specific
separation technique.
The assigned
techniques are as
follows:

20. Station 1: Hand Separation
Materials: Mixture of coins
of different amount
What to do: separate the
coins according to their
amount

21. Station 2: Decantation
Materials: Mixture of rice
and water, beakers
What to do: separate rice
from water

22. Station 3: Filtration
Materials: mixtures of tea and
water ,wipes as substitute for
filter paper, funnel
What to do: separate tea from
water using wipes as substitute
for filter paper

23. Station 4: Magnetic
Separation
Materials : Mixture of iron
nails and flour, magnet
What to do: separate iron
nails and flour using magnet

24. Station 5: Evaporation
Materials: mixture of salt and
water, multifunction cooker (as
substitute to alcohol lamp,
beaker and matches)
What to do: separate water
from salt through evaporation


25. Station 6: Hand Picking
Materials: Mixture of
different colors of rubber
band
What to do: separate the
rubber bands by color

26. Each group
representatives will
present to the class your
assigned method
/technique of separating
mixtures through writing,
describing, or
demonstrating the steps
of doing it.

27. ANALYSIS:

28. Based on the
activity, what are the
different techniques
of separating
components of a
mixture?

29. Decantation
Filtration
Magnetic
Separation
 Evaporation

30. Winnowing
Threshing
 Sublimation
 Distillation

31. Sifting or sieving
 Sedimentation
•Hand Picking

32. COMPLETE THE
TABLE BELOW:

HETEROGENEOUS Use of Magnet
salt and water HOMOGENEOUS Evaporation

35. ABSTRACTION:

36. How mixtures are
be separated?
Describe each
briefly.

37.  Hand Picking- This
method involves
simply picking out
all the unwanted
substances by hand

38. Decantation- he
process of pouring
away a liquid while
leaving a solid (often
a precipitate)
behind.

39. Filtration- is used
here to remove solid
particles from the
liquid. Various filtering
agents are normally
used like filtering
paper or other
materials.

40. Magnetic Separation-
When one substance in
the mixture has some
magnetic properties then
this method is quite
useful. Strong magnets
are commonly used to
separate magnetic
elements.

41. Evaporation -, the
solution is heated until
the organic
solvent evaporates
where it turns into a
gas and mostly leaves
behind the solid
residue

42. APPLICATION:

43. 1. A Junk shop is loaded
with a mixture of different
materials ( e.g. bottles,
paper, tin can) if you are
the owner of the shop
what technique you are
going to use to separate
the mixture? Why?

44. 2. In your Araling Panlipunan on
proper waste management how
are you going to deal with a
trash can inside the classroom
loaded with a mixture of garbage
( paper, plastics, candy
wrappers).
What method you are going to
use to separate them?

45. 3. A married couple
(husband and wife) is a
mixture because they are
considered as one in the
eyes of God and land. Do
you consider of
separating this kind of a
mixture? Why?

46. ASSESSMENT:

47. What I have learned…
 Directions: Using the frame below. Complete
the starter phrases based on what you know
about ways of separating components of
mixtures.
My chosen word is ___________________
I know that I know ____________________
First I know ___________________________
In addition, I know ____________________
Finally, I know _______________________
Now, you know something that I know
_____________________________

48. ASSIGNMENT:

49. Study the
concepts learned
on pure substance
and mixture for a
summative test
next meeting.

50. Thank you…
