The document describes an activity where students create mixtures by combining various substances like salt, powdered milk, oil, and gravel with water. They observe and record the properties of each mixture, noting whether the components can still be distinguished. The concluding sections define homogeneous and heterogeneous mixtures, with homogeneous mixtures having uniform composition throughout and heterogeneous mixtures having a non-uniform composition where the separate components can still be identified.

2. Activity 1
Forming & Describing Mixtures
Let’s find out: How can you form mixtures?
Let’s use these materials: four glasses, tap water,
teaspoon, salt, powdered milk, oil,
gravel
Let’s do it this way:
1. Half-fill the four glasses with tap water.
2. Put a teaspoon of salt in one glass. Stir. Label it as “Mixture A.”
3. Put a teaspoon of powdered milk in another glass. Stir. Label it “Mixture B.”
4. Put a teaspoon of oil in the third glass. Stir. Label it as “Mixture C.”
5. Put a teaspoon of gravel in the fourth glass. Stir. Label it as “Mixture D.”
6. Leave the set-ups for about 1 minute. Observe each set-up. Compare them
7. Fill in the table below.

2. Which mixtures can you still distinguish the components? Give the
components.

Describe non-uniform mixtures

5. What are the characteristics of each mixture?
How do each mixture differ?
What did you learn in this activity?

6. Homogeneous refers to a substance that is
consistent or uniform throughout its volume.
They consist of a single phase, be it liquid, gas,
or solid, no matter where you sample them or
how closely you examine them.
Examples: Air is considered a homogeneous
mixture of gases.

7. A heterogeneous mixture is a mixture having a
non-uniform composition. The composition
varies from one region to another, with at least
two phases that remain separate from each
other, with clearly identifiable properties. If you
examine a sample of a heterogeneous mixture,
you can see the separate components.

13. Answer the Guide Questions:
 Are the mixtures the same?
How do they differ?
Describe uniform and non-uniform mixtures.

14. IV. ASSESSMENT
Directions: Describe uniform mixture.
Describe non-uniform mixture.
