The document outlines a science lesson on types of solutions, focusing on definitions and properties of unsaturated, saturated, and supersaturated solutions. It includes objectives, examples, key terms, and questions to assess understanding, along with activities for students to demonstrate their knowledge. The lesson emphasizes the significance of solutions in daily life and includes tasks to perform experiments and engage students in further study.

Types of Solutions

2. MELC : Investigates properties of unsaturated or saturated
solutions.
Quarter : 1
Week : 5
Objectives:
A. Defines solute, solvent and solution;
B. Identifies the types of solution;
C. Performs an experiment about the types of solutions; and
D. Appreciates how solutions influence our daily lives.

3. How are you going to describe a homogeneous mixture?
 The components are evenly distributed throughout and
has a uniform appearance.
How about heterogeneous mixture?
 The components are not evenly distributed throughout
and it doesn't have a uniform appearance.
Can you give some examples of homogeneous and
heterogeneous mixture?
Let’s have a recap.

4. Solute  is a substance dissolved in another substance
Solvent  is a substance that dissolves a solute, resulting in a solution.
Terms to remember…
Solutions  is a special type of homogeneous mixture composed of two
or more substances.
Substance  a particular kind of matter with uniform properties.
Mixtures  is a material made up of two or more different substances
which are physically combined.

5. Questions:
Which of the following pictures show a solution?
How are you going to describe a solution?
What are the components that make up a solution?
Look at the pictures below and answer the following questions.
Let’s start…

6. Questions:
1. What are the differences of the solutions above?
2. Which of these pictures show a saturated and unsaturated solution?
3. How about supersaturated solution?

7. A solvent is a substance that dissolves the solute.
Water is the universal solvent.
A solute is a substance dissolved in a solvent.
COMPONENTS OF A SOLUTION
water
sugar

8. AQUEOUS SOLUTION
 is a solution of any
substance in which solvent is
water.
SOLUBILITY
 is an ability of the solute to
be dissolved in a solvent.
SUGAR SOLUTION
Dissolving of sugar in water

9. TYPES OF SOLUTIONS
UNSATURATED
SOLUTION
SATURATED
SOLUTION
SUPERSATURATED
SOLUTION

10. 1. UNSATURATED SOLUTION
It contains less than the
maximum amount of solute.
It can dissolve more solute.
Can we dissolve any amount of solute in water?
What will
happen if we keep
on adding more
solute to the
solution?

11. 2. SATURATED SOLUTION
 It contains the maximum amount of solute
dissolved by a given amount of solvent.
If you add more solute to the solvent, it will
no longer dissolve because the solution has reach
its saturation point.
SATURATION POINT
 is the point beyond which the substance will
no longer dissolve in the solution

12. The presence of an excess solid
which can no longer dissolve is an
evidence that a solution is SATURATED.
Thus becoming SUPERSATURATED.

13. 3. SUPERSATURATED SOLUTION
 Holds more solute than it normally
could in its saturated form.
 Solution that is more concentrated
than a saturated solution.
 Supersaturated solutions are unstable.

14. Let’s wrap it up…
