SEPARATING MIXTURES:
EVAPORATION AND FILTRATION
for SCIENCE 6 Quarter 1/Week 6
SELF-LEARNING KIT
FOREWORD
This learning kit is prepared for the learners to enrich their
knowledge on the different ways of separating mixtures
through evaporation, and filtration.
The activities in this learning kit will strengthen the
learner’s basic knowledge on how to separate substances in
a mixture as stated in MELC that they can use and apply on
their daily activities.
It is expected that the learners have to share their
knowledge and expertise to their friends on separating
mixtures and apply it on their day to day life.

OBJECTIVES:
K: Identify methods to separate mixtures.
S: Describe how certain mixtures can be separated
through evaporation and filtration.
A: Dispose the garbage properly after the activity.
LEARNING COMPTENCIES:
Describe techniques in separating mixtures such as
decantation, evaporation, filtering, sieving and using
magnet. (S6MT – 1d – f – 2)

PRE-ACTIVITIES/PRE-TEST:
Let’s See What You Already Know
Before you start studying the SLK, answer the following test
to find out how much you already know about the topic to be
discussed. Write your answer in your science notebook.
A. Draw a happy face
if the mixtures that can be
separated through evaporation and sad face
if NOT
Write your answer in your science notebook.
1. water and alcohol
4. Muddy water
2. salt and water
5. Stones and pebbles
3. sugar and water
B. Identify the mixture that can be separated through filtering.
Write Yes if it can be separated by filtering and No if NOT. Write
your answer in your science notebook.
1. Tamarind extract
4. Soil and water
2. Salt and water
5. Lime and water
3. Sand and gravel
Let’s Explore
A salt solution is made up of water and salt. How do you
separate these two substances? Find out in the following activity.
4
Activity 1: Separating Mixtures through Filtration and Evaporation
You will need the following materials:
1 tablespoon sand
1 teaspoon salt
2 tablespoons water
a plastic bowl/drinking glass
pan/tin container
stove
Safety Precautions Before, During the Activity:
1. Be careful in handling glass wares.
2. Be sure to do the experiment with supervision of your
parent/guardian or an adult.
3. DO NOT smell or taste any material especially if you are not
familiar with it.
4. Use material with care for the purpose for which it is
intended.
5. Carefully follow the procedure.
Do the following:
1. Mix the water, sand, and the salt in a pan/tin container. Stir
continuously until the salt is dissolved in the water.
a. Answer these questions: Does sand dissolved in water? Can
you still see the salt? Why do you think it happens?
2. Separate the sand from the mixture. Pour the water, sand and
salt mixture into a clean container using a cloth, strainer, or a
filter paper to pass it through.
Questions:
a. Were you able to separate the sand from the mixture?
5
b. Is salt separated from water? Why do you think it happens?
c. Is salt still found in the mixture?
d. How can we separate dissolved salt from the mixture?
Please proceed to the next activity.
3. Pour the water and salt mixture in a pan/tin container over the
stove. Let it boil until all the water has gone or evaporated.
4. Observe the residue on the bottom of the container.

Questions:
a. What happens to the water after boiling for some time?
b. Does salt evaporate with water?
C. What is left behind at the bottom of the pan/tin container?

II. WHAT I NEED TO LEARN
Evaporation is a technique used to separate out
homogeneous mixtures that contain one or more dissolved salts.
The method drives off the liquid components from the solid
components. The process typically involves heating
the mixture until no more liquid remains.
For a solution made up of a solid and liquid, the process of
evaporation can be an effective technique of separation.
Evaporation is the process of transforming a liquid into a gas. When
the liquid evaporates, it leaves behind the solid component of the
solution. In the case of salt solution that you tested in the preceding
activity, the water evaporated and left the salt as residue in the
container. Salt making is the best example of evaporation process
which is beneficial to all.
Filtration is the process of separating solid substances from a
liquid through the use of a filter paper or any cloths that can be
used as a filtering medium. These solid residues are trapped by the
filter process. It is a separation process in which a mixture is passed
through a filter that allows one component to pass through
uninhibited but blocks another component from passing through.
Filtration works best when the solute isn't dissolve in the
solvent. For instance, sand and water can be separated through
filtration as both compounds do not dissolve with each other.
However, salt and water would not be separated through
filtration as they dissolve with each other.
Vocabulary Words:
1. filter – an apparatus containing a filter medium
2. filter medium – example filter paper or cloth
3. residue – an usual small amount of something that remain after
a process has been completed or a thing has been removed
4. filtrate – something that remain after a process has been
completed or a thing has been
removed.

SYNOPSIS
Mixtures can be physically separated
by using different techniques. This SLK
discussed some of the ways of separating
components in the mixtures such as
decantation, evaporation, filtration, sieving
or sifting, and using magnet or magnetizing.
Separation of substances is very
important in our day to day life. Learners
who have learned concrete idea and
knowledge on how to separate substances
in a mixture can obtain important and pure
substances
from
products
in
the
community. The unwanted particle from the
mixture can be made into another product
which is beneficial to all.
Thank you for trying your best in
accomplishing this Self Learning Kit (SLK).
Share the things you have learned with your
family and friends.
