1. LESSON PLAN IN SCIENCE GRADE 8
I. Objectives:
At the end of the lesson the student will be able to;
a) Discuss the Three Laws of Motion.
b) Distinguish the differences of the Three Laws of Motion.
c) Propose the Three Laws of Motion as a part of our daily life.
.
II. Content:
Topic: Newton’s Three Laws of Motion
Reference: Science 8 (page 181-200)
Materials: rope, gallon of water, ball and string
III. Procedure:
a) Prelim Activities:
Teacher’s Activity Student’s Activity
Greetings
Good Morning Class!! Good Morning, Teacher.
Prayer
Class, let us all rise and put ourselves in the
presence of the lord as we pray.
Ms. Dela Cruz Leads the Prayer.
Checking of Attendance
Is there any absent for today’s class?
Very good! Perfect Attendance
Nobody is absent, Teacher.
Reminders
Class, the deadline for wearing your
complete uniform is on July 15, 2019.
Yes, Teacher.
2. b) Developing Activities:
The class will be divided into three groups and the teacher will
conduct an experiment and a re-enactment to the students and they will
observe. Let them analyse what is happening after the experiment and the
acting.
c) Activity:
The class will be divided into three groups; each group will pick a
representative. The representatives will pick their given situation and act it
in front of the class and the others may observe. Let them discuss their
given situation after the re-enactment.
They will be judged by the given criteria
Performance 20%
Clarity of the presentation 30%
Creativity 20%
Behaviour 30%
Total 100%
For the experiment, the students must follow the given instructions:
Rules of the day
Minimize your voice during class
discussions.
Do not answer in chorus.
Take down notes.
Listen to the lesson proper.
Yes, Teacher.
3. 1) Ask for student volunteers and tell to each grab the opposite
end of the rope. Make them both pull the rope so that the
rope is fit, but neither the students is moving from their
original position.
2) The second experiment will be hanged on the rope from the
pulley with equal lengths on either side. Fill one gallon of
water halfway and fill the other gallon of water all the way.
Tie each gallon to opposite ends of the rope, holding each
gallon at an equal distance from the floor. The, let go of the
gallons
3) The third experiment will be place the rod so that each side
of the rod is balanced on a level surface with an equal
height. Each ball should have a string and tie each string to
the rod.
Let the students observe what happens when the first ball drops and hits
the second ball.
Allow them to discuss possible conclusions.

d) Analysis:
The teacher will now ask the following questions to the students:
4. 1. Can you now identify our topic for today?
2. Why do we need to know this topic?
e) Abstraction:
Let us begin our explanation of how Newton changed our
understanding of the Universe by enumerating his Three Laws of Motion.
Newton's First Law of Motion:
I. Every object in a state of uniform motion tends to remain in that
state of motion unless an external force is applied to it.
This we recognize as essentially Galileo's concept of Inertia, and this
is often termed simply the "Law of Inertia".
Newton's Second Law of Motion:
II. The relationship between an object's mass m, its acceleration a, and
the applied force F is F = ma. Acceleration and force are vectors (as
indicated by their symbols being displayed in slant bold font); in this law
the direction of the force vector is the same as the direction of the
acceleration vector.
This is the most powerful of Newton's three Laws, because it allows
quantitative calculations of dynamics: how do velocities change when
forces are applied. Notice the fundamental difference between Newton's
2nd Law and the dynamics of Aristotle: according to Newton, a force
causes only a change in velocity (acceleration); it does not maintain the
velocity as Aristotle held.
5. Newton's Third Law of Motion:
III. For every action there is an equal and opposite reaction.
This law is exemplified by what happens if we step off a boat onto
the bank of a lake: as we move in the direction of the shore, the boat
tends to move in the opposite direction (leaving us face down in the water,
if we aren't careful!).
f) Application:
The teacher will now ask the following questions to the students:
1. What are the differences of the Three Laws of Motion?
g) Assessment:
The teacher will give a quiz to the certain topic:
Identification
1. An object will stay in motion, unless an external force acts upon it.
__________________
2. In every action there is an equal or opposite reaction. _____________
3. An amount of force needed to make an object to stop. _____________
Essay
4-5. why do we need to learn the three laws of motion?
IV. Evaluation:
The teacher will ask the question to the students:
6. 1. What is the importance of the three laws of motion?
2. How does the Three Laws of Motion affect our lives?
V. Assignment:
Instruction: Answer in a short bond paper.
1. Research for the factors that may affect the motion of a certain object.
2. Determine the formulas of the law of Inertia, Acceleration and Inter-action.
