*Preliminary Assessment
On a ¼ sheet of pad paper, define the
following terms: Distillation, chromatography,
filtration/sifting, evaporation, magnetism.
A. Statement of the problem.
Directions:
Think carefully about
the following
statements. Are they
true or false?
Circle your answer.
a. In filtration, the
filtrate is always a pure
liquid. True/False
b. Drinking water
can only be obtained
from seawater by
distillation.
True/False
c. The fractional
distillation of miscible
liquids is only possible if
the liquids have
different boiling points.
True/False
d. Paper
chromatography is a
physical method for
separating mixtures.
True/False
e. Mixtures have
fixed melting and
boiling points.
True/False
Draw on a short bond
paper an illustration of
chromatography. To be

1. Distillation-this is the separation
technique where two miscible liquids
(liquids that mix together) are separated.
2. Chromatography -is the separation
technique used to separate soluble
substances using a media and a solvent.
3. Filtration or sifting is a method in which
you use the property of size to separate
mixtures.
4. Evaporation-the liquid portion of the
solution is allowed to evaporate, leaving
the solute behind.
5. Magnetism can be used to separate
mixtures of solid.
A person is allergic to the yellow dying
agent used in manufacturing certain
candy coatings. Although the coatings
appear as one color, the colors are often
made from a combination of dyes. What
separation method can be used to
determine if a yellow dying agent was
used?

C. Inference
1. Define each separation technique using
the vertical bullet list.

3. Distillation
•this is the separation technique where two miscible
liquids (liquids that mix together) are separated.
Chromatography
•-is the separation technique used to separate
soluble substances using a media and a solvent.
Filtration or sifting
•is a method in which you use the property of size to
separate mixtures.
Evaporation
•liquid portion of the solution is allowed
toevaporate, leaving the solute behind.
Magnetism
•can be used to separate mixtures.
2. Show pictures for each technique.

5. 3. Differentiate mixture from a substance
Substance is an element or a compound
(two or more elements that have reacted
chemically in a fixed proportion by
mass).We can separate the various
constituents of a compound substance by
a chemical process (reaction).
Mixture is formed when two or more
substances are mixed in any proportion.
The constituents of a mixture can be
separated by a physical process.
4. Using available resources inside the
classroom, and the materials by the
teacher, the group should be able to
choose one separation technique and
present it in class in a creative manner.
The groups are given 10 minutes only to
discuss and 5 minutes to present.
5. Group the class into 5 groups with 10
members.
Example:

6. The students choose chromatography. Instead
of color, they will represent it as the human
race. And after series of investigations, the
group separates the girls in the group from the
boys.
Criteria:
Group discipline-10 points
Accuracy of the presentation-15 points
Total: 25 points
D. Verification
Base on the picture of distillation, answer the
following questions.
1. The liquid solution is boiled in the boiler. The
solvent evaporates. The solvent changes from a
_____ to a gas (water vapor).
2. The vapor moves out of the boiler. It goes into
the inner tube of the cooling section.
3. The cold water in the outer tube cools the
vapor. This makes the vapor condense. The
vapor changes from a ___ to a liquid.
4. The liquid drips into a container. It is pure. It
has been distilled. It has no solute dissolved in it.
5. What happens to the solute? The solid solute
stays behind in the boiler. It is now dried up. It is
in solid form.
Answers:
1. Liquid
2. Okay
3. Gas
4. Okay
5. Okay
Final Assessment:

7. On a ¼ sheet of pad paper, the students are
asked to write a brief explanation on as to how
separation of techniques is important.
Criteria:
Neatness-5 points
Accuracy of the answer-10 points
Total: 15 points
Separation techniques are important for
us to know the components of materials.
Being able to know its components is
important for us to be aware of it.
