A suspension is a heterogeneous, cloudy mixture where solute particles do not dissolve and instead remain suspended in the solvent and may eventually settle out of the solution over time. Suspensions have cloudy appearances and the undissolved solute particles can be seen floating in the solution. Examples of suspensions discussed in the document include flour mixed with water used as a thickening agent, oil and vinegar mixtures used in food preparation, and sand mixed with water used in construction materials.

with solvent?( settle at the bottom / float in the
water)
3. Describe the appearance of the mixture done. (
cloudy)
4. What kind of mixture did you make? ( suspension)
5. In what preparation can this mixture be useful?
(food preparation as thickening agent) In which test
tube did the chocolate powder dissolve faster?
6. What made the chocolate powder in a certain test
tube dissolve faster?

8. Conclusion:
Answer the questions to come up a conclusion on
the activity you have performed.
 1. What is the name of the mixture that you make?
(gaw-gaw)
 2. Based on the appearance and characteristics,
what type is this mixture? (suspension) 3. So
therefore, what is a suspension and how can this
be useful? (A suspension is a heterogeneous
cloudy mixture in which solute-like particles settle
out of a solventlike phase some time after their
introduction. This gaw-gaw mixture can be used in
food preparations as thickening agent.)

 Record the appearance of the mixture.

12. Questions:
1. When the 2 ingredients are
combined, what do they become? (
mixture)

make? ( suspension)
4. In what preparation can this
mixture be useful? (for vegetable
salads) *see reference

13. Conclusion:
 Answer the questions to make a conclusion
from the activity you performed.
1. What is the name of the mixture that you
make? (oil and vinegar mixture)
2. Based on the appearance and
characteristics, what type is this mixture?
(suspension)

14.  3. So therefore, what is a suspension and
how can this be useful? (A suspension is a
heterogeneous cloudy mixture in which
solute-like particles settle out of a solvent-like
phase sometime after their introduction. This
oil-vinegar suspension can be used in salads,
marinades, sandwiches and other food
preparations.) *see reference

15. Activity 3: Describe the

20. EXPLANATION
Posting / reporting
activity result by group

21. Ask:
 As you mix the solute particles in a solvent,
what did you make?
 How did the solute particles behave when
mixed with the solvent?
 Describe the appearance of the mixture you
have done.
 What kind of mixture did you make?
 Describe the appearance of suspension.
 Show other examples of suspensions then
describe.
 Give the uses of these suspensions: (for food,
medicines, beautification, etc.)

22. ELABORATION
Suspension is a heterogeneous mixture, which has
particles that do not completely dissolve and settle
down at the bottom. Suspensions are cloudy
mixtures.
Some substances do not dissolve completely in
solvents. The particles that do not dissolve settle
down at the bottom of the container. An example of
mixture is sand and water used as construction
materials. You had observed that particles settle down
at the bottom of the glass. The particles do not spread
evenly unlike the solution. This mixture is called
suspension.

23. Flour mixed with water form a mixture and is
used as thickening agent in food
preparation. The particles of flour do not
dissolve but float in the water. The mixture of
flour and water is called a suspension.

24.  A mixture of oil and vinegar form a
suspension. The oil particles do not dissolve
in vinegar. Instead, the vinegar slowly sinks to
the bottom of the container. This mixture is
used for vegetable salads, marinades and
other food preparations.
 Some liquid medicines, like milk of magnesia
that can be used as laxative and
cotrimoxazole used as antibiotic are also
suspensions.
