III. PROCEDURES
Teacher’s Activity Students’ Activity
A. Preparation

a. Greetings
Good morning class!
Good morning sir!
 b. Class structuring
Fix all your things and pick up
these pieces of paper under
your chair.

c. Prayer
Kindly lead the prayer, Rhain! Heavenly father, we thank you for the
blessings that you gave, protect us from
any harm and guide us in our lessons
today, amen.

Thank you! Class be seated.

Thank you sir!

d. Checking of Attendance
Class who is absent today?
None Sir!

Ok, thank you!

e. Classroom rules

Before we start, I just want to

remind everyone about our
science class that: always be
responsible and respectful
towards your classmates and
teachers; be attentive in our
class; and raise your hand if you
have questions or if you want to
answer. Yes sir!
Is that clear?

B. Review

From the previous lesson, you

already learned about friction,
Will you give me the definition of
it? Yes! Carlo! The force that acts in the opposite
direction of motion when two surfaces
 come in contact.

That is correct! Please be seated

Carlo!

Next, friction is a force that acts

in what direction of a movement?
Why do you think so, Diane?
Opposite Sir!

Thank you, Diane! You may take

your sit.

C. Motivation

Class, Please stand up and listen

to my instructions.
Each Row will jump
consecutively. I will count to
three and you will jump one at a
time, is that clear class? Yes Sir!

You may take your sit.

Thank you sir!

From your activity, I will ask you

some questions.
Karl, What happened to you when
you jumped? I went up, sir!

Correct you went up!

What happened then after you

went up? I went down, sir!
Yes, Roland!

Very Good you went down after

jumping.

Why do you think you went down

after jumping up?
 Yes, Ruby!

Because of the Gravity sir!

Very Good, Ruby!

D. Lesson Proper
With that phenomena we will
further understand as we go
along with the discussion. Our
topic for today is all about
Gravity and the factors affecting
it. Before we start let us first
determine the unlocking of
difficulties. Based from the
activity, how would you describe
Gravity? Gravity is a force that pulls all objects
Yes, Kaye? towards the ground. It is also known as
gravitational force

Thank you!
Gravity puts all things on Earth
and the universe in order. They
do not float away. Gravity helps
keep the planets orbiting around
the sun and moons revolving
around the planets.

What do you think will happen Everything will float, Sir.

without gravity? Yes, Grace?

Very good!

Now from the visual, there are

two people that is dropping
different objects at the same
time a keys and a pen. They have
different masses, which of the
two will reach the ground first?
a. The rock.

b. The keys.

They will reach the ground at the same

time.
Yes, King!

Well done King!

What is the reason that the keys

and pen reach the ground Yes, It is the gravity, Sir.
Anna?

Thank you Anna! That is correct!

It will reach the ground at the

same time because of the
gravity, same distance and as
long as there is no air resistance.

There are 2 factors that affect

gravity that is the mass and
distance.

Remember that, everything that

goes up will always come down
because of the gravity.

Do you know the person on the

screen? Yes, Rolando!

That is correct, he was known for

what? Mary?
He is Isaac Newton, Sir!

Very Good!

He saw an apple falling from a

tree, and it got him thinking
about the mysterious force that
He proposed the universal gravitational
pulls objects to the ground.
law in his book Principia Mathematica in
Is Mass and Weight the same? 1687.
Yes, Bench!

Very Good!
Mass is the measure of how much
What are the measurement that matter there is an object and weight is
we use in mass and weight? Yes, measure of the pulling force of gravity
on an object.
Anna!

That is correct!

The mass of an object is

constant; it does not change
whether you are here on earth or
in the moon. The weight of an
object will change if it is in a
place with a lesser gravity.

We use kilogram to measure

mass and Newton on measuring Because they have different
the weight. gravitational pull sir!

Why does our weight is not the

same in earth and moon? Yes,
Darell!

That is correct! The gravitational

pull on earth is 9.8 m/ s2 while in
moon its gravitational pull is
1.62 m/s thus making our weight
2

different.

To further explain the gravity and

the factors that affect it let’s do
the activity, “Investigating
Gravity”

Pre – Activity
In this activity you will identify
the factors affecting gravity. You
will be grouped in to 3. Write
your group leader’s name,
members, grade and section on
your activity sheet.
The materials needed are:
Pen/pencil
Eraser/crumpled paper
Chalk/ small ball
Activity Proper
Before we start let us discuss first
the procedure.
1. Pick up the two objects in your
choosing and drop them at the
same time and the same
distance.
2. Record it on your activity
sheet.
3. Now drop the two objects at
the same time but in different
distance.
4. Record it on your activity
sheet.

Objects Dropped at the same

 distance table

ground at
the same
time (yes
or no)

Objects Dropped at the

5. Write Yes or No in the table

based from your activity.

Guide questions:

1. Did the two object dropped at

the same distance reach the
ground the same time?
2. Does the mass matter, is the
heavier one reached the
 ground first?
3. How about when it got
dropped at different distance?
which of the 2 reached the
ground first?

*You have 10 minutes to do

the activity and choose 1
representative to explain your
answers in front.

Possible answer:

Post – Activity

1. Did the two object dropped at the Yes sir, they reached the ground at the
same distance reach the ground same time.
the same time?
No, sir because the gravitational pull of
the two is the same, they reached the
2. Does the mass matter? Did the ground at the same time.
heavier one reached the ground
first?

The shorter distance reached the ground

first sir.
3. How about when it got dropped
at different distance which of the
2 reached the ground first?

E. Application
I have a short video here for you
to analyze and later I will ask
questions about it.
From your activity, and video of
two objects dropped at the moon,
answer these questions: Yes sir, because they have the same
gravitational pull.
1. Did the two objects reached
the ground at the same time?
Yes, Kurt!

Thank you! Kurt!

 Because of the gravitational
pull of the moon, they will
reach the ground at the same
time

2. Did the hammer become No sir, the mass of an object is constant

lighter in the moon? whether you are in earth or moon, but
Yes, Lance! its weight will change because of the
gravity.

Very good! Lance!

The mass of the hammer did
not change, but its weight
changed because of the
gravity.

3. What would happen if there’s

no gravity? Edrian? Everything will float away sir!

Well done, Edrian!

Without gravity, everything
will be out in order our solar
system would fall apart and
we would not have a
comfortable life. Gravity is a force that pulls all objects
F. Generalization towards the ground.
1. How will you describe gravity?

Mass and distance.

2. On what two factors does
gravity depend on?
It would eventually go down because of
3. If I throw and object upward the gravity pulling it.
what will happen after it
reached the top?
 IV. EVALUATION
