Learning Competencies/Objectives
At the end of the lesson the learners should be able to:
1. Describe force
2. Compare the kinds of forces
ELICIT
MATERIALS
The teacher will show different pictures and ask the students LED TV/ LCD
what they observe.
Projector,
Images
A.
B.
C.
Questions such as the following may be asked:
1. What did you observe in the given pictures?
2. Why do objects move in different ways? Why are
some objects faster than others?
3. What makes objects stay in place?
ENGAGE
Students will watch a video clip about forces and
its kind
( https://www.scholastic.com/.../activities/...force-andmotion-6-studyjams-interactive-science-activities/ )
Guide Questions:
1. What is force?
2. How do object move?
3. What is the reason why objects move? stop?
4. Cite the forces describe in the video

II.
Select student that will do the following,
A. Pushing the table
B. Carrying a bag
C. Lifting a chair
Guide Question:
How do you move the object? What do think is
the reason why you move the objects?
III.

Designing the activities
The following activities were designed to accomplish the
learning goals and objectives. Divide the students into
(three) 3 groups.
pen ,book, table,
manila paper,
Each group will be given activity sheets. ( materials are
assigned ahead of time)
Group 1
Situation 1
1. Place a book on top of a table as shown in Figure 3b.
Guide Questions:
Q4. Is the book at rest or in motion?
Q5. Are there forces acting on the book? If yes, draw the
forces acting on the book in a ¼ manila paper.
scissors, used
tissue paper roll,
used cardboard,
Popsicle sticks,
glue, small and
medium
rocks,rubber
bands
3. Let one member of your group push the book in one
direction and another member push it in the opposite
direction at the same time with the same amount of
push (force).
Guide question:
Q6. Did the book move? How will you make the book move?
Group 2
1. Gather all the materials needed (scissors, used tissue
paper roll, used cardboard, Popsicle sticks, glue,
small and medium rocks,rubber bands).
2. Cut the cardboard 2.5” by 2.5” in length and height.
Follow the image below
3. Place two small rocks in both sides of the seesaw.
Observe.
4. After placing it, remove and place another rocks with
different sizes in both sides of the seesaw. Observe
Guide Questions:
1. What did you observed in the following objects?
a. Two small rocks
b. Rocks with different sizes
EXPLAIN
Call representative from each group and let them present
their work. Explain only if necessarily.
Ask also the students to describe or demonstrate how they
can achieve the given conditions above.
ELABORATE
The teacher will then elaborate the definition of force and its
kind.
A force is a push or a pull. A force can give energy to an
object causing the object to start moving, stop moving, or

change its motion. The SI unit for force is Newton (N) PowerPoint
(1kgm/s2). Forces occur in pairs and can be either Presentation
balanced or unbalanced (www.makemegenius.com/forces)
If two forces acting on an object are equal in magnitude
but opposite in direction, they are considered as balanced
forces. These forces must lie along the same line.
- If the forces acting on an object are balanced, the object
either stays at rest or continues to move at constant velocity.
- If the forces acting on an object are unbalanced, the motion
of the object will change.
EVALUATE
Worksheet#____
Worksheet
Instruction: Complete the Venn Diagram below to compare
the balance and unbalanced forces
EXTEND
Observe your surroundings. Take a photo of the different
signage’s that the kinds of forces exhibit, Afterwards Create
a prolific photo collage.

Presentation
In Mathematics, positive and negative signs are
used in Cartesian plane to indicate a value while
in the Science terms algebraic signs + and – are
used to indicate the direction of forces. Unlike
signs are used for forces acting in opposite
directions and vice versa.
