Welcome to the wonderful world of Science!
Hello there! I am Spongebob Squarepants
with my pet Gary and we will be your guide
in this Intervention Material for you to learn
the process of filtration. Let us begin!
Ayayayayayay!
You have already learned in the previous lessons that
mixing things are very important to everyone and to our
daily needs but in the other hand there are lot of mixtures
around us that are needed to be separated in order to
properly use their components so that we can benefit in
using them. Filtration is one of the ways, methods or
techniques of separating mixtures.
Filtration is a process used to separate solid particles from
it’s liquid component just like the process of decantation.
But in the process of filtration, you need to use a filter,
which is a porous material or other tools for removing the
impurities or solid particles from a liquid that have passed
through it. Ayayayayayay!
The learning competency of this lesson is to
enumerate the techniques in separating mixtures
such as decantation, evaporation, filtering, sieving
and using magnet. Ayayayayayay!
Our main objective for this lesson is for
you to describe filtration as a process of
separating mixtures. Ayayayayayay!
Before proceeding with today’s lesson, let us first
check your prior knowledge about filtration. Read
each item carefully then encircle the letter of the
correct answer. Ayayayayayay!

A. decantation C. filtration
B. evaporation D. sieving
2. The liquid part of the mixture that passes through the screen.
A. filter C. filtration
B. filtrate D. fluid
3. Any object that holds or traps the solid particles on it’s top and letting the

Are you confident enough on you answers in this
pre - test? Do not worry, everything is just fine. On
the later part of our lesson you can discover all the
correct answers in this pre - test. Ayayayayayay!
On your past lesson, you have learned that evaporation
is process of changing the phase of liquid water to
water vapor with the use of heat. The purpose of
evaporation is to get the soluble solid in a mixture and
let the liquid go. For our review, encircle the pictures
that show evaporation in separating mixtures.
Ayayayayayay!
Nice job! Do you want to learn a another way of
separating mixture? If evaporation is used in
separating a soluble solid and a liquid, this time you
will learn a technique that separates insoluble solid
from a liquid in a much effective way as compared to
decantation and this process is called filtration.
Ayayayayayay!
Our friend Patrick and Sandy needs help! Please help
them by just answering their questions. Write your
answers on the box provided after the situations.
Ayayayayayay!
My mother wants to cook ginataang alimango. She bought
grated coconut for this dish. She wants me to get the coconut
milk (gata) and throw away the coconut pulp because we
will not be needing it. What should I do? Why?
Answer:
I love pancit canton that is why tomorrow morning I want to
prepare this as my breakfast. My problem is, what should I
do to separate the noodles with the boiling water? Please
also tell me why should I do that? Thank you.
Answer:
Our friend Patrick and Sandy are very happy on what you
have done to solve their problems. Now it is about time to
see if you have given the correct answers to their prob-
lems. They are found in the next page together with their
explanation. Ayayayayayay!
Sandy may separate the coconut milk from the grated coconut meat by adding
small amount of hot water and putting it into a clean cloth and squeezed it forcibly so
that the coconut milk will be extracted from it’s pulp. She must use a clean cloth to
block the coconut pulp from getting into the extracted coconut milk to avoid
impurities in her coconut milk.
On the problem of Patrick, he just need a colander or a strainer. He will just
carefully pour the hot water and pancit canton noodles on top of a colander / strainer
and let the hot water pass through the colander / strainer that will collect the pancit
canton noodles. Colander / Strainer is the best tool to use in this job because of their
holes to let unwanted liquid to be separated in a much effective manner as compared
to the different improvised techniques.
The technique or way of separating mixture that solves the problems of Sandy
and Patrick is called filtration.
Filtration is a technique which an insoluble solid is separated from the liquid
part that uses filter like mesh cloth, filter paper, any porous materials or tools with
holes. Filtration is used for separating solid and liquid mixtures only.
The liquid which has passed through the filter is called the filtrate. The solid
part that cannot pass the holes / pores of the filter is called residue.
In Sandy’s situation the filtrate is the coconut milk, the residue is the coconut
pulp and the clean cloth serves as the filter.
On the problem of Patrick, the colander or a strainer is the filter, the hot water
is the filtrate while the pancit canton noodles is the residue.
I will be going to show you a simple experiment that will
give you a deeper understanding on the differences
between the processes involve in sedimentation,
decantation and filtration. Do you know that by using these
three processes together you can turn a muddy water into a
crystal clear water. Ayayayayayay!
1. Prepare a water and mud mixture.
2. After mixing it, let the mixture rest for 30 minutes.
The mud settles down at the bottom of the beaker by the process of
sedimentation. Sedimentation is when a heavier components of the mixtures settle
down after leaving the mixture undisturbed for sometimes. The solid particles that
settles down at the bottom is called sediment.
3. Transfer the water on top of the settled mud by tilting the beaker to another empty
clean beaker.
When you remove or transfer the water above the sediment this process is
called decantation. The water that have been transferred to the clean beaker is called
decantate. In the process of decantation the decantate liquid is still cloudy that means
the water has still small particles of mud in it.
4. Put a fine cloth on top of a new clean beaker and transfer the decantate liquid to the
new beaker by letting the decantate pass the fine cloth.
This process now is called filtration because of the use of fine cloth or any
porous materials to filter the fine particles of solid in the mixture. The liquid that
passes through the fine cloth is no longer called decantate because this process is not
considered as decantation, instead the liquid that passes the filter or the fine cloth is
now called as filtrate. Sad to say, the filtrate that passes the fine cloth are not clear
enough because the pores of the fine cloth are not small enough to filter all the residue
in the mixture.
5. Prepare a filter paper, funnel, stirring rod and another clean beaker. Fold properly
and place the filter paper in the funnel and pour the water obtained in the filtration
with cloth and wait until it reaches the beaker under the funnel. You can use a stirring
rod to directs the flow of the liquid to the funnel to avoid spillage.
By just looking at the filter paper before and after the filtration, you can see the
big difference in its color due to the fine mud residue that was blocked by the tiny
pores of it. As a result, the filtrate now is crystal clear and free from any impurities.
