III. PROCEDURE

TEACHER’S ACTIVITY STUDENTS’ ACTIVITY

A. Preliminary Activities

1. Greetings

Good morning students. Good morning, Ma’am. Good morning

Classmates.

3. Checking of Attendance

Is there any absent in the class? None, ma’am.

Excellent!

4. Setting of Classroom Rules

Before we start our lesson, let us

Recall our online classroom rules.
  Always turn on your camera and mute your
microphone. Unmute only when permitted.
 Click “Raise Hand” icon if you want to answer or
ask questions and click “Lower Hand” icon if you’re done.
 If you need to say something without interrupting the class,
you may use our chat box.
 The chat box is an academic space; it means
that is only for matters related to academics.

B. Developmental Activities

1. Review
Before we start with our new lesson,
Let us have a review first.

Last time, we discussed about the topic MIXTURE:

And what is a mixture?

A mixture is a combination of more

than one substance.

Exactly, and what are the two types of mixtures?

Homogenous and Heterogonous
mixture.

Very good! To review your understanding about

the two types of mixtures, let’s have a game,
namely: Where do I belong?

On your whiteboard, write Homo if the given example

belongs to Homogenous mixture and
write Hetero if Heterogeneous mixture.

Let’s start.

1. Orange juice 1. Homo

2. Milk 2. Homo
3. Soupy Noodles 3. Hetero
4. Salt in water 4. Homo
5. Fruit Salad 5. Hetero

Very good! Most of your answers are correct.

Now, based on our given examples
define Homogenous mixture.
Orange Juice, Tea, and Vinegar are
Homogenous mixtures; it is a mixture in
 which the composition is uniform
throughout the mixture.

Exactly, How about the definition of

Heterogonous mixture?

Heterogeneous mixture is a mixture in

which the composition is not uniform
throughout the mixture.

Very Good!

2. Drill

To start our new lesson for today,

we will be having a game entitled “Decode the word”

Instruction: Each number stands for a letter of the alphabet.

Click the raise a hand icon if you want to answer.

Are you ready? Yes, ma’am

a. 19 1 20 21 18 1 20 5 4
a. SATURATED
b. 19 15 12 22 5 14 20
b. SOLVENT
c. 21 14 19 1 20 21 18 1 20 5 4
c. UNSATURATED
d. 19 15 12 21 20 5
d. SOLUTE
And lastly, our topic for today is all about
19 15 12 21 20 9 15 14 19
SOLUTIONS

C. ELICIT

Let us examine again the following

pictures of some homogenous and heterogonous
mixtures we saw earlier.

Based on this examples,

Which do you think is a solution?

Click the Raise hand icon if you think

that the given example is a solution.

1. Orange juice- Homo

2. Milk - Homo
3. Soupy Noodle- Hetero (Students will click the raise a hand
button depending on their answers
4. Salt in water- Homo
5. Fruit Salad – Hetero

D. ENGAGE

Based on your answers,

Orange Juice, milk and Salt in water are examples of Solution.

So, what do you think is a solution?

A solution is a homogeneous mixture

of two or more substances.

Exactly! What else?

(The students will give their answers.)

How these solutions formed?

(Orange Juice, milk and Salt solution)

E. EXPLORE

Now, we will have an activity.

And last time I already grouped you into 5 and you already assigned
the LMNOP (Leader, Material manager, Note taker, Observer, and a Presenter)
per group.

Before we do that, let us recall

The guidelines in doing an activity. What
Is the first step? Be cooperative.

That’s right. What else? Show respect to your groupmates.

Follow directions correctly.

Alright, proceed now to your respective room.

And if you have questions, just go back here in our Main
room. Let us start the activity.
(Students will enter their respective
rooms)
ACTIVITY WORKSHEET
TITLE: STIR ME UP

Materials needed.
- Transparent Cups
- Spoon
- Any dissolvable Substance (sugar, salt, powdered juice)
- Glass of water

Procedure
1. Add one spoon of your dissolvable substance in the glass of
water. Dissolvable Substance:
Dissolving Substance:

2. Stir the dissolvable substance in the water.

Write you observation

3. Add more spoons of your dissolvable substance into the

solution. Write you observation

4. Dispose properly the used materials and clean the working place.

F. EXPLAIN

Let us examine and hear

your Observations in the activity.
Each group shall have a
designated Speaker to present what
they’ve observed In your activity.
(The students will present their work.)

(The teacher will assist the learners in the

Presentation. The teacher will give the
Correct scientific term for every needed
Observation.)

G. ELABORATION

In your activity, you learned that solution is formed by mixing two substances.
And what are these substances?
 The dissolvable substance and the
dissolving substance.
That’s right. And what is the dissolvable
and dissolving substance in your activity?
The dissolvable substance are sugar,
salt and powdered juice. While the
dissolving substance is water.

The dissolving substance in a solution is called Solvent.

And the substance being dissolved is called the Solute.

Let’s have more examples.

Identify which is the solvent and which is the solute.

1. Cup of coffee
Solvent: Water, Solute: Coffee
2. Maple Syrup
Solvent: Water, Solute: Sugar
3. Gelatin
Solvent: Boiling Water, Solute:
Gelatin Powder

Very good! Let us focus now to the solute.

Why do solute dissolves in solvent?

It is because of the property of solution called “Solubility”

Solubility is the ability of a solute to dissolve in a solvent.

Let us now discuss the types of solution based on solubility.

During your activity earlier, these are the results.

(Picture of results)

By observing these pictures, what do you think

is the difference between the saturated and Unsaturated Solution?
(The students will give their
answers.)

The Unsaturated Solution is a type of

solution where the solute completely
dissolves, leaving no remaining substances.

The Saturated Solution is a solution in which

no more solute can be dissolved in the
solvent.

To further understand the lesson, let

us have an activity.
 (The students will do the
activity.)

Activity
1. Make a Venn Diagram about Unsaturated and Saturated
Solution Show their similarities and differences.
2. Cite examples of solution and distinguished the solvent and solute.

Let us take a look in your works.

(The students will present their work.)

Let us recall our lesson today.

What are the two components of a Solution? the two components of a Solution are
Solute and Solvent.

Correct! What is the difference between Solute and Solvent?

Solvent is the dissolving substance and
Solute is the dissolvable substance.

What are the two types of solution based on solubility?

The saturated Solution and
Unsaturated Solution
And What is the difference between this two?
The Unsaturated Solution is a type of
solution where the solute completely
dissolves, leaving no remaining
substances.

The Saturated Solution is a solution in

which no more solute can be dissolved
in the solvent.

Exactly.
