5. 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
6. Let’s do it this way:
⦁ Half-fill the four glasses with tap water.
⦁ Put a teaspoon of salt in one glass. Stir. Label it as “Mixture A.”
⦁ Put a teaspoon of powdered milk in another glass. Stir. Label it “Mixture
B.”
⦁ Put a teaspoon of oil in the third glass. Stir. Label it as “Mixture C.”
⦁ Put a teaspoon of gravel in the fourth glass. Stir. Label it as “Mixture D.”
⦁ Leave the set-ups for about 1 minute. Observe each set-up. Compare
them.

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.

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.
