2. IV: PROCEDURES
A. Reviewing previous lesson or
presenting the new lesson
ELICIT (Dice Breaker!)
Before we begin our new lesson, let’s have a quick review of our lesson yesterday
through an activity. The title of our activity is Dice Breaker! I have here a die and each number
has a corresponding question on it. I’ll ask a student to roll the die. He/she will answer
the corresponding question. Is it clear? Any question? Okay, let us begin.
1. How many natural occurring elements?
Ans: 92
2. How many synthetic elements?
Ans: 24
3. What is synthetic elements?
Ans: a chemical element does not occur naturally on earth.
4. What are the three-reaction involved in synthesis of new
element in the laboratory?
Ans: 1. Capture reaction
2. Fission reaction
3. Fusion reaction
5. What is nuclear reaction?
Ans: produces of heavier product nucleus and emits a very high
electromagnetic energy.
6. Give an example of synthetic elements at least 2 elements.
Ans: may vary
B. Establishing a purpose for the
lesson
Students will answer the following question to reveal the acronym.
- P-symbol of phosphorous
- O- reacts with hydrogen to create water.
- LAR- solar minus so
- I- symbol of iodine
- TY- an abbreviation of lawyer with no at
The word that will be revealed is POLARITY

3. C. Presenting examples instances
of the new lesson
ENGAGE (Cooperative Learning)
GUESS WHAT AM I? (Pass the ball)
I will show you a picture of two mystery molecule after that you will analyze it where is the EVENLY
DISTRIBUTED OF ELECTRONS AND PROTONS, AND NOT EVENLY DISTRIBUTED OF
ELECTRONS AND PROTONS.
POLAR MOLECULE NONPOLAR MOLECULE
D. Discussing new concepts and
practicing new skill #1
EXPLORE (Inquiry-Based Learning)
Pre-activity Discussion
To begin our lesson, Let’s conduct an experiment related to Polarity.
Activity: Polarity Experiment
Objective: observe how water and dish washing liquid behave when they are mixed with a cooking
oil.
I have here the materials needed for the experiment. Let’s see if you could still remember the names
of the following:
Stirring rod
Beaker
Water
Oil

4. Dish washing liquid
Direction: I will group you into 5 groups. First, mix the water and oil then observe their reaction.
Second, mix the liquid detergent and oil then observe their reaction. After that, present it to class and
give your opinion. Just choose one representative each group. Right after, I will ask some questions
base on your experiment.
Questions:
1. What did you observe or notice to the water and oil?
2. What did you observe or notice to the dish washing liquid and oil?
3. Can you determine the polar and non-polar?
E. Discussing new concepts and
practicing new skill #2
Analysis (explain)
- The learners will present their outputs to the class and explain their answers.
F. Developing mastery LECTURE
What do polar and non-polar mean?
- In simple terms, polar means oppositely charged, and non-polar means equally charged.
Covalent bonds can be polar or non-polar. To understand the difference between polar and
non-polar bonds, it is essential to comprehend electronegativity.
POLAR MOLECULE
- There is unequal or asymmetrical distribution of electrons among the atoms of molecule.
Example: WATER

5. OCTET RULE
- States that atoms tend to gain, share or transfer electrons in order to attain a stable 8 valence
electron configuration.

6. Example: TUG OF WAR

7. NONPOLAR MOLECULE
- There is equal or symmetrical distribution of electrons among the atoms in a molecule.
Example: OXYGEN GAS
Oxygen gas is a NONPOLAR MOLECULE.

8. To get the electronegativity value of each element we will use PERIODIC TABLE.

9. Electronegativity Difference Bond type
0-0.4 Nonpolar covalent bond
0.5-2.0 Polar covalent bond
2.1 above (between metals and nonmetals Ionic
Let’s use Water as an example.
Sine the value is 1.4, and states 0.5-2.0 is polar covalent bond, Water is Polar.
“the greater the electronegativity differences, the greater the polarity of the molecule.”
for the Oxygen Gas
Which means that Oxygen Gas is NONPOLAR.

10. NOTE:
- The polarity of the molecules does not depend solely on the type of bond present but also on
the shape of the molecule.
- There are molecule who are polar in bond but nonpolar in shape of the molecules
Maybe you are wondering how it happen?
let’s use the Carbon Dioxide as an example.
making it a Polar molecule.

11. however, based on the Molecular Geometry or the shape of molecules Carbon is a linear molecule
making it a nonpolar.
5. Finding practical applications
of concepts and skills in daily
living
- Learners will relate how polarity of attitude can affect their decision making by answering the
question, how do we usually act when we hear something negative about us from other people?
What should be the right thing to do?
6. Making generalization and
abstractions about the lesson
I will ask some questions about our topic.
1. What is Polar?
2. What is non-Polar
3. How to solve electronegativity?
7. Evaluating learning - learners will answer the quiz.
Using the electronegativity table of elements, solve for the EN difference and distinguish whether
the molecule is polar or non-polar covalent.
1. Br2
2. AgCl
3. SF3
4. NH3
5. CaCl2
8. Additional activities for
application or remediation
EXTEND (assignment)
Search about how Valence Shell Electron Pair Repulsion theory is done and how it affects the polarity
of molecules.
V: Remarks
VI: Reflection
B. No. Of learners who require
additional activities for remediation
C. Did the remedial lesson work?
No. Of learners who have caught up
with the lesson

12. D. No. Of learners who continue to
require remediation
E. Which of my teaching strategies
work well? Why did these works?
F. What difficulties did I encounter
which my principal or supervisor
can help me solve?
G. What innovation or localized
materials did I use discover which
I wish to share with other teachers?
