I. OBJECTIVE
Identify the types of colloids
II. CONTENT Uniform and Non-Uniform Mixture
Materials ppt presentation of the lesson, laptop, projector, activity sheets, manila paper, marker
References MELC – CLMD BOW in Science 6 page 19
III. PROCEDURE
A. Elicit (Recall) Identify if the following is a colloid or not. Write C if it is a colloid and NC if it is not. Write your
answers using your journal or notebook.
1. gelatin
2. mayonnaise
3. Soft drinks
4. vinegar
5. Smog

B. .Engagement Nowadays, we have created a lot of mixtures. From food, medicine and even industrial
(Motivation) materials, a variety of products are made up of different mixtures. There are different types of
mixtures. One of these is based on the phase of the dispersed substance and on what phase it
is dispersed in.

C. Exploration (Discussion Group Activity

(Developing of Mastery
1. What is aerosol made of?
2. What is the dispersing medium of a smoke?
3. What phenomenon is created when the dispersed colloid particles scatter light?
4. What are the two components present in the colloid?
5. How can we categorize colloids?
6. In what category of colloids does marshmallow belongs?
7. What does sol mean?
8. Is dust a colloid? If so, to what category does it belongs?
9. What is the dispersing medium of a mayonnaise?
10. What is a colloid?

Colloids are one of the primary types of mixture. It is a type of mixture in which solid or liquid
particles are dispersed uniformly throughout a gas, liquid or solid. Colloid particles maybe seen
in a beam of light such as dust in air and a shaft of sunlight. Blood, whipped cream and fog are
 examples of colloids.
To be classified as colloid, the substance in dispersed phase must be larger than the size of a
molecule but smaller than what can be seen with the naked eye.

The component typically present in a relatively small amount is called dispersed phase and the
substance or solution throughout which particulate is dispersed is called the dispersion medium.
Colloid creates a Tyndall effect, it is the effect of light scattering in colloidal dispersion, if no light
is shown, then it is a true solution. This effect is used to determine whether a mixture is a true
solution or a colloid.
A common method of classifying colloids is based on the phase of the dispersed substance and
at what phase it is dispersed. The types of colloids
are:
1. Sol-is a colloidal suspension with solid particles in a liquid.
2. Emulsion-formed between two liquids
3. Foam- is formed when many gas particles are trapped in a liquid
4. Aerosol-contains small particles of liquid or solid dispersed in a gas.

E. Elaboration Complete the statement below.

(Application and
Generalization) The ____________ is a type of mixture in which solid or liquid particles are dispersed
uniformly throughout a gas, liquid or solid. It is classified into four types,
_____________, ____________, ___________ and _____________..

4. What is the most abundant particle in a colloid?
a. dispersing mediums b. dispersing phases c. miscible d.

5. Why is milk categorized as emulsion?
a. because settling cannot separate the components of homogenized milk.
b. because settling can separate the components of homogenized milk
c. The colloid's particles of milk are larger.

6. Soda pop, whipped cream, and beaten egg whites are examples of what type of
colloids?
a. foam b. Emulsion c. Sol d. Aerosol
7. How would you differentiate a colloid mixture from a solution?
a. The colloid's particles are larger. c. A colloid has a positive charge
b. The colloid's particles are smaller. d. A colloid has a negative charge.
8. A colloid is a stable combination of particles of one substance that are dissolved or
suspended in a second substance.

9. An _________ is a sol with the continuous phase a gas. Fog is an _________ of
water droplets.
a. aerosol b. emulsion c. sol d. foam
10. An _________ is a sol in which the suspended particles are liquid droplets and the
continuous phase is also a liquid. The 2 phases are immiscible, otherwise a solution
would form.
