Title: Describing the Appearance and Uses of Uniform and Non-Uniform Mixtures
Introduction:
In this workbook, we will be exploring the different types of mixtures, specifically uniform and nonuniform mixtures. Mixtures are a combination of two or more substances that are not chemically
combined. Uniform mixtures are also called homogeneous mixtures, where the substances are evenly
distributed throughout the mixture. Non-uniform mixtures are also called heterogeneous mixtures,
where the substances are not evenly distributed throughout the mixture.

Title: Understanding Uniform and Non-Uniform Mixtures
Lesson Objective: Students will be able to describe the appearance and uses of uniform and non-uniform
mixtures.
Introduction:
Have you ever mixed water and sugar together to make lemonade? What about sand and gravel to make
concrete? These are examples of mixtures, which occur when two or more substances are combined
together. In this lesson, we will learn about two types of mixtures: uniform and non-uniform.
Part 1: Uniform Mixtures
Uniform mixtures, also known as homogeneous mixtures, are mixtures where the substances are evenly
distributed throughout the mixture. The appearance of a uniform mixture is the same throughout.
Examples of uniform mixtures include salt water, air, and brass.
Activity:
To demonstrate the appearance of a uniform mixture, we will mix food coloring and water together. The
resulting mixture will be the same color throughout.
Discussion:
Why do you think uniform mixtures are useful? What are some real-world examples of uniform
mixtures?
Part 2: Non-Uniform Mixtures
Non-uniform mixtures, also known as heterogeneous mixtures, are mixtures where the substances are
not evenly distributed throughout the mixture. The appearance of a non-uniform mixture can vary
depending on where you look. Examples of non-uniform mixtures include soil, salad dressing, and cereal
in milk.
Activity:
To demonstrate the appearance of a non-uniform mixture, we will mix oil and water together. The
resulting mixture will have two distinct layers, with the oil floating on top of the water.
Discussion:
Why do you think non-uniform mixtures are useful? What are some real-world examples of non-uniform
mixtures?
Part 3: Uses of Uniform and Non-Uniform Mixtures
Both uniform and non-uniform mixtures have practical applications. For example, uniform mixtures are
often used in the production of medicines, where it is important that the active ingredients are evenly
distributed throughout the final product. Non-uniform mixtures are useful in many ways, such as in the
production of concrete or asphalt, where different sized particles are needed to create a strong material.
Activity:
Divide students into small groups and have them research and present real-world examples of both
uniform and non-uniform mixtures.
Conclusion:
In this lesson, we learned about uniform and non-uniform mixtures. We discovered that uniform
mixtures have an even appearance throughout and non-uniform mixtures have an appearance that
varies depending on where you look. We also learned that both types of mixtures have practical
applications in everyday life.

Module 3 Title: Techniques in Separating Mixtures
Grade Level: Sixth Grade
Introduction:
Mixtures are a combination of two or more substances that are not chemically combined. They can be
separated into their individual components using various techniques. In this module, we will explore
different techniques used for separating mixtures and conduct activities to understand each method.
Lesson 1: Decantation
Decantation is a technique used to separate a mixture of two immiscible liquids. In this technique, the
mixture is left to stand undisturbed until the heavier substance settles down. The liquid on top is then
carefully poured out without disturbing the sediment.
Activity: Students will be given a mixture of oil and water and will be asked to separate them using
decantation.
Lesson 2: Evaporation
Evaporation is the process of converting a liquid into a gas by heating it. This technique is used to
separate a mixture of a solid and a liquid. The liquid is heated until it evaporates, leaving the solid
behind.
Activity: Students will be given a mixture of salt and water and will be asked to separate them using
evaporation.
Lesson 3: Filtration
Filtration is a technique used to separate a solid from a liquid by passing the mixture through a filter
paper. The solid particles are trapped in the filter paper, while the liquid passes through.
Activity: Students will be given a mixture of sand and water and will be asked to separate them using
filtration.
Lesson 4: Sieving
Sieving is a technique used to separate a mixture of solids with different particle sizes. The mixture is
passed through a sieve, which separates the particles based on their size.
Activity: Students will be given a mixture of rice and sand and will be asked to separate them using
sieving.
Lesson 5: Using a Magnet
Using a magnet is a technique used to separate a mixture of magnetic and non-magnetic substances. The
magnet attracts the magnetic particles, leaving the non-magnetic particles behind.
Activity: Students will be given a mixture of iron filings and sand and will be asked to separate them
using a magnet.
Conclusion:
In conclusion, mixtures can be separated into their individual components using various techniques.
Students can learn about these techniques and apply them in their everyday life. By conducting these
activities, students can gain a deeper understanding of the physical properties of matter and the ways in
which mixtures can be separated.
