The document outlines the concept of mixtures, differentiating between homogeneous and heterogeneous mixtures, along with methods for separating them. It provides definitions, examples, and classification activities related to mixtures, including practical separation techniques such as filtration and distillation. The lesson also encourages students to relate the topic to their daily lives and spiritual reflections.

1. MIXTURES
(UNIT TWO, LESSON 2.3)
BY MARGIELENE D. JUDAN

2. LESSON OUTLINE
Mixture
Types of Mixtures
Separating Mixtures

4. MIXTURE
2 or more substances held
together by physical forces
They do not create a new
substance

5. TYPES OF MIXTURES
Homogeneous Mixture
Heterogeneous Mixture

6. HOMOGENEOUS MIXTURE
Homo means “same”
Components are evenly
distributed
Cannot be separated by
physical means

7. EXAMPLES
Solutions
Colloids
others

8. HETEROGENEOUS MIXTURE
Hetero means “different”
Components are not evenly
distributed
Can be separated by
physical means

9. EXAMPLES
Suspensions
Emulsions
others

10. Identify the following if it is a
homogeneous or
heterogeneous mixture:

11. Sand + water

12. Answer: Heterogeneous
They are distinguishable.
Water
Sand

13. Juice powder + water

14. Answer: Homogeneous
You can’t distinguish the
parts of the mixture
They have been evenly
mixed.
Water??
Juice Powder??

15. Homogeneous or heterogeneous?

16. Answer: Heterogeneous
They are distinguishable and
can be physically separated.
Red M&M’s
Orange M&M’s
Yellow M&M’s
Brown M&M’s
etc

17. Is air a mixture? If so, what kind?

18. Yes. Air is composed of
78% nitrogen, 21% oxygen, and less
than 1% of argon, carbon dioxide,
and other gases. Since you cannot
distinguish them, air is a homogenous
mixture.

19. COMMON METHODS OF
SEPARATING MIXTURES
Picking
Magnetic Separation
Decantation
Distillation
Solar Evaporation
Filtration

20. PICKING
large solid to solid mixture

21. MAGNETIC SEPARATION
Solid to solid
metal mixture

22. FILTRATION
Solid(not
dissolved) to
liquid mixture

23. SOLAR EVAPORATION
Solid
(dissolved) to
liquid mixture

24. DECANTATION
Liquid to liquid
non-dissolvable
mixture
Solid (settled
on bottom) to
liquid mixture

25. DISTILLATION
Liquid to liquid
mixture

26. SEPARATING MIXTURES SUMMARY
Method Component 1 Component 2 Example
Picking solid (large
chunks)
solid rock and gravel
Magnetic
Separation
solid (metal) solid sulfur powder
and iron fillings
Decantation liquid or solid
(non-
dissolvable)
liquid sand and water
oil and water
Distillation liquid liquid oil and water
alcohol and
water
Solar
Evaporation
solid
(dissolvable)
Liquid salt and water
Filtration Solid (non-
dissolvable)
Liquid or solid sand and gravel
sand and water

27. Separating mixtures are not limited to
one method. For example, you could
separate sand and water through
decantation, filtration, and
evaporation, though some methods
work best in different situations.

28. Activity: (1 whole sheet of paper)
1. Write a short paragraph about the
mixtures you see at home, and tell
why are they important to us. (5 pts)
Then, relate the lesson to your
spiritual life. (5 pts)

29. Assignment: Notebook
I. Classify whether it is a homogeneous or
heterogeneous mixture.
1. air
2. sand water
3. ink
4. different types of stones
5. oil and water

30. Assignment: Notebook
II. Identify which method is best to use in
order to separate the following mixtures:
1. M&M’s chocolate
2. Alcohol and water
3. Saltwater
4. Sand and gravel
5. Iron fillings and talc powder
