(Simple Machines)
31. Comprehension Check:
• What are the six simple machines
mentioned in the video?
• How will you describe each?
• What are the uses of each?
• Why do we use simple machines?
• Why are simple machines
important?
32. Discussing new concepts and practicing new skills #1
Direction:
Some machines are so simple that
we do not even realize that they
are machines. Identify each
simple machine described below.
The shapes of the boxes have
been provided to guide you. Write
the answers on your drill board.
33. • 1. Machine for opening cans
• 2. Machine for cutting paper
• 3. Machine used for moving sand from one
place to another
• 4. Machine used for pulling nails
• 5. Machine used for catching fish
34. Discussing new concepts and practicing new skills
#2
Pantomime Strips:
Orient the pupils about pantomime.
Have each group pick a strip from
the box.
While a representative is
pantomiming the rest of the groups
should guess the kinds of simple
machines and their uses.
Every correct answer of the group
will be given points.
35. Developing mastery (leads to Formative Assessment 3)
Plan It Out: “Damage house”
-Group by pair
-Each pair will identify all the
simple machines needed to
repair the house then classify
them according to the 6 simple
machines.
36. What are the simple machines
needed to repair the house?
How did you classify them?
Plan It Out:
37. Finding practical applications of concepts and skills
in daily living
Differentiated Activity in three groups with 12 to
13 members, each group will have a leader.
Direction: Group 1 will stay inside the
classroom. Group 2 and 3 will stay outside in
the designated study areas.
Reminders to pupils before doing the activity:
Be polite by listening attentively with each
other during group activity.
Group Presentations
-10 minutes only for group sharing and
planning
- 3 minutes only for each group presentation
40. Group’s Task
Each group is given activity sheet to
answer.
*Group 1: Crossword Puzzle.
Identify the simple machine
being described.
*Group 2: Where do I belong?
Using the different pictures
classify what simple
machine they belong.
* Group 3: What I am?
41. Making generalizations and abstractions about the
lesson
1. What are the different simple
machines?
2. How will you describe each
simple machine.
3. Did you show politeness with
each member of your group
during the activity? Why is
politeness important?
42. Evaluating learning
• Directions: Read carefully, and then
choose the correct answer by writing
the letter on your answer sheet.
1. Which of the following best explains
why
lifting a heavy object with a
single fixed
pulley and rope makes the task
seem
easier?
a. Less force is needed to lift the
43. and Sing
c. Movable and Pull d. Block and
Tackle
3. A stiff bar that moves about a fixed
point
is a
a. lever b. wheel and
axle
c. wedge d. inclined
plane
4. Which simple machine would stairs be
an
example?
a. a wedge c. a pulley
b. an inclined plane d. a lever
5. Which is an example of a wheel and
axle?
44. Additional activities for application or
remediation
Give three safety
measures in handling
simple machines.
49. The Lever
a rigid bar that is free to turn about a
fixed point called the fulcrum
Every Lever has three (3) parts:
1. Resistance Force, Input Force or Load, What
you are trying to move or lift.
2. Effort Force or Output Force - The work done
on the Lever.
3. Fulcrum – A fixed pivot point.
52. • The Fulcrum (fixed pivot point) is located
between the Effort (Input) and the Resistance
(Output) Forces.
• The effort and the resistance move in
opposite directions.
• The effort force pushes down in order to lift
the resistance or load.

62. The Pulley
• A pulley changes the direction of the force:
– Instead of lifting up, you can pull down using
your body weigh against the load (what is being
lifted)
• A pulley gains nothing in force, distance or
speed
70. • Functions of the screw
– To fasten things – the standard screw or nuts &
bolts.
– Drill bits are screws used to make holes.
– A jackscrew is used to lift heavy objects; car jack.
• When you turn a screw:
– The input force is changed by the threads into an
output force.
– The output force pulls the screw into the materials.
– Friction between the threads & the material holds
the screw in place.
