Separating Mixtures:
DECANTATION
Day 1
I. OBJECTIVES:
Content Standards:
The learners demonstrate understanding of
different techniques to separate mixtures.
Performance Standard:
The learners should be able to separate desired materials
from common and local products.
Learning Competencies/Objectives:
Enumerate techniques in separating mixturessuch as
picking, winnowing, decantation, use of magnet, sieving,
filtering, and evaporation.
Separate the components of common solid mixtures by
winnowing.
Write the LC code for each
(S6MT-Id-f-2)

Multimedia Presentation, Pictures, and Materials for the Activity
I will asks
review questions
and you will
search the
answer around
the room.
What is
winnowing?
How can
mixtures be
separated in
winnowing?
Describe how the
technique
winnowing is
done in
separating
mixture.
What is sieving?
How can
mixtures be
separated in
sieving?
Describe how
the technique
sieving is done
in separating
mixture.
Have you tried
cooking rice?
How do you do it?
Decantation is a process of
separating mixtures by
removing a layer of liquid,
generally one from which a
precipitate has settled. A
mixture of an insoluble solid
in liquid is allowed to stand.
If the solid is denser than the
liquid, it will settle at the
bottom if kept undisturbed for
some time. This process where
particles settle at the bottom of
the liquid is called
sedimentation.
Lets do Activity
4.3 Let it Sink and
Separate.
I will give initial
instructions about
the activity.
Let us have the
following
materials to be
used in our
activity.
A beaker is a
simple container
for stirring,
mixing and
heating liquids
commonly used in
many laboratories.
A graduated
cylinder is
used to measure
liquid volume.
The unit is the
milliliter (mL).
Glass
Stirring rod,
glass rod, stirring
rod or stir rod is a
piece of laboratory
equipment used to
mix chemicals and
liquids for laboratory
purposes
A timer is a
specialized
type of clock
for measuring
time intervals.
sand
Wood
shavings
water
PROCEDURES:
1. Gather all the needed materials.
2. Place two heaped tablespoons of soil or
sand into one beaker and half fill with water.
3. Mix the sand and water. Leave the water to
settle for 1 minute then attempt to pour off
only clean water into the measuring cylinder.
4. Stop when the water starts to become
cloudy (translucent). Repeat the activity
increasing the time left to settle the sediment.
5. Record your observation in the table.
Take note of the following terms in
describing the mixtures:
Transparent Light can pass through
and objects are clearly seen e.g. window
Translucent Semi-transparent (fuzzy
image)
e.g. milky glass
Opaque Light cannot pass through
e.g. brick

You are going
to present your
group output
on the activity.
I will give
feedback about
the result.
1. Can the solid particles
be separated from water
right after mixing without
letting it settle at the
bottom of the container?
2. Did waiting a longer
time improve the clarity of
water? Why?
Let’s answer the
guide questions
3. Do you think water
becomes potable
after decanting?
Why?
4. What could water
be used for after
decanting?

tomorrow so
please do not
