PROCEDURES
A. Reviewing previous lesson
or presenting the new
lesson
Let the students classify
some compounds as either
ionic compound or covalent
compound.
Let them recall the definition
of ionic and covalent bond
based on their answer. Ask
the students to differentiate
these two types of bond.
Demonstrate to the students
an activity that shows the
formation of ions in a
solution (ex. Table salt in
water can make the water a
good conductor of
electricity). Ask the students
how is this change of
electrical conductivity
becomes possible.
Gather some answers to the
students.
Let the students recall first
how table salt forms.
Students will recall that table
salt ( NaCl) is a product of
ionic bonding or the transfer
of electron from a metal to a
nonmetal which causes an
electrically neutral atom of
metal to become positively
charge and an electrically
neutral atom of nonmetal to
be negatively charge.
B. Establishing a purpose for
the lesson
Post a question on the board
that says “If metals can bond
Introduce to the students the
process of ionization or the
with nonmetals and
nonmetals can bond to
nonmetals, is it possible for
metals to bond with metals?”
Solicit answers from the
students and ask them how it
will happen.
(Answers must be noted to
be used as the lesson
progresses).
Another question to be
posted is this “ Is the bond
that exists among metals can
be the reason for its
properties?”
C. Presenting
examples/Instances of the

formation of electrically
charged atoms or molecules.
Tell to the students that ions
can be grouped as positively
charged ions or cation and
negatively charged ions or
anion. Mention also that ions
can be an atom or it can be
a molecule.
Explain to the students that
properties of a solution
depends on the type of ions
that are found on it.
Show the students some
pictures of metals which
display some of its
characteristics. Ask them to
explain what characteristic of
metal is shown on the
pictures.
Post a list of ions on the
board as examples.
( Make a list of these
characteristics on the board)
Present to them pictures of
some food products or drinks
that are sources of ions
needed by our body.
Divide the class into small
groups and ask them to
Ask the students to form 6
small groups for the activity.
The students will identify the

groupings of ions as cation
and anion, as well as atoms
and molecules).
perform Activity # 5 Bonding
Among Metals.
ions from the food products
and drinks that will be
assigned to them by their
teacher. They also need to
group these ions as cation or
anion and as an atom or as
a molecule.
Students must share the
result of their investigation in
the class.
E. Discussing new concepts
and practicing new skills #
2
The students will report their
findings on the said activity in
the class.
( Note for any misconception
that may arise during this
procedure)
After the students have able
to report their work, it is time
to explain to them the
answers for the said activity.
Any misunderstanding that
the teacher noted must be
explained thoroughly to the
students until they grasp the
correct idea.
Tell to the students that
aside from the presence of
ions in foods and drinks that
we eat, there are other
important uses of ions.
Each group will investigate
some uses of ions. Some of
the possible topics to be
assigned to the students are
the following: fluorescent
light, neon lights, battery,
ionosphere, sickle cell
anemia.
The students will research
on how ions are involved on
each topic.
( Assigning of these topics
must be done a day before
the lesson so that the
students can research and
bring their materials in class
on the assigned date.)
F. Developing mastery
(leads to Formative
Assessment 3)
Go back with the pictures you
have presented as examples
for the characteristics of
metals, ask the students to
explain the pictures based on
the concept of metallic
bonding and the “sea of
electrons”.
Students will be sharing their
research in the class and
they are expected to discuss
how they find ions useful.
G. Finding practical
application of concepts
and skills in daily living
Ask the students to suggest
some ways on how they can
use the lesson in their daily
living.
The class will have an open
forum about food
supplement, vitamins and
energy drinks they used and
how these things help them
in their daily lives.
( Motivate them by giving
additional points for those
who can answer correctly)
H. Making generalizations
and abstractions about the
lesson
Call for at least three
volunteers that may sum up
the lesson.
The teacher can prepare
incomplete statements that
will be completed by the
students to guide them what
to generalize.
To generalize the lesson ask
the following to the students:
1. What is ion?
2. Define ionization.
3. What are the two
types of ions?
4. Give examples of
ions as atom and as
a molecule.
5. What are some of the
uses of ions in our
lives?
