2. At the end of the lesson, the class
will be able to identify the different
simple machines.

3. Simple Machines
Considered to be building blocks of machines
It helps the people make their work easier
The 1st machines are often called “the 6 simple
machines”
LET'S FIND OUT WHAT THESE
MACHINES ARE! :-)

4. The 6 SIMPLE MACHINES:
click the machine you want to know :-)
Lever Wheel & Axle Screw
Inclined Plane Pulley Wedge
Back Next

5. Lever
Resistance force /
load Effort force
constructed from a
beam attached to
ground by a hinge, or
fulcrum
The fulcrum balances 2
forces: an effort
force and a
resistance force, or
load

6. These are some other examples of
Lever machines :-)

7. Wheel And Axle
A wheel with a rod,
called an axle,
through its center lifts
or moves loads.
They're everywhere! A
large circle (wheel)
connected to a smaller
circle (axle) links
distance traveled and
power needed in an
incredibly useful way

9. Inclined Plane
A slanting surface
connecting a lower
level to a higher level.

10. These are some other examples of
Inclined Plane :-)

11. Pulley
A simple machine that
uses grooved wheels
and a rope to raise,
lower or move a load.
Each section of string
supporting the
movable pulley
system decreases the
force needed to move
the load

Pulley machines :-)

13. Wedge
An object with at least
one slanting side
ending in a sharp
edge, which cuts
material apart.

15. Screw
An inclined plane
wrapped around a
pole which holds
things together or lifts
materials.

16. These are some other examples of
Screw :-)
Back HOME EXERCISE! :)

17. Now, are you familiar with the simple
machines you've seen?
Let's test how you remember them.
We will have some few exercises!
Click the “Start” button if you are
ready. Let's go! :-)

18. What am I?
You can usually find me during flag ceremonies, I
help the flag reach the top of the pole.

19. OOPS! THAT'S NOT ME.
YOU CAN TRY AGAIN

20. CORRECT! :)
I am a pulley and you can usually find me on
top of the flag pole. It is easier for me to pull
down and push up because of the movable
rope that supports me :-)

21. What am I?
I help Mr. Porter put the box to the truck.
Lever Wheel and Axle Wedge
Pulley Inclined Plane Screw
Back Next question

22. OOPS! THAT'S NOT ME.
YOU CAN TRY AGAIN

23. CORRECT! :)
I am a inclined plane and you can always use
me as a guide to transfer heavy things inside a
truck

24. What am I?
Hey-o-hey-o, said the dwarf as he lift me to whack
that rock into two.
Lever Wheel and Axle Wedge
Pulley Inclined Plane Screw
Back Next question

25. CORRECT! :)
I am a wedge and you can always use me to
cut materials apart because I usually have
slanting side ending in a sharp edge :-)

27. What am I?
I am Mr. See-saw.
Lever Wheel and Axle Wedge
Pulley Inclined Plane Screw
Back Next question

28. CORRECT! :)
I am a lever and I can be a seesaw for you and
your playmate :-)

30. What am I?
“I need you,” said Mr. Hinge, “the Door and I can't
connect.”
Lever Wheel and Axle Wedge
Pulley Inclined Plane Screw
Back Next question

31. CORRECT! :)
I am a hinge. A hinge is a kind of screw that
you can see between the side of the door and
the wall attaching it. It is the one that makes
the door open properly :-) Like this:

33. What am I?
The cyclist is looking for me, his bike won't move
without me.
Lever Wheel and Axle Wedge
Pulley Inclined Plane Screw
Back Next question

34. CORRECT! :)
I am a wheel and an axle. A bike is an
excellent example of it, because of the wheel
that makes it to move and a screw to secure
it :-)

36. What am I?
“Cut-cut-cut” said the scissors. I will cut your
paper into half

I am an inclined plane and sometimes I can
also be a slide in playgrounds and fun
parks :-)

42. CONGRATULATIONS! You have successfully
identified the different kinds of simple
machines. You might think of it as “simple”
yet it has many uses, and those are the
special meanings in physics. When a force
moves an object, that is what we now call
“work” :-)
Next

43. I hope you have learned enough information
about our topic today. Always remember,
examples of these things are not simple
machines:
Next

44. This is not a simple machine. This is
WALL-E. A complex robot machine.
Next

45. Neither is Bumblebee from
transformers. This is really a complex-
transforming robot.
Next

46. Well yes. Washing machine makes
your life easier, BUT this is not
identified as simple machine! It has
complex functions in it
Next

47. Especially this! This is a machine. But
this is machine gun, not for simple
purposes. You know what I mean.
Next

48. BUT this. We are not machines, we
are just SIMPLE :-)
THANK YOU FOR TRYING OUR LEARNING OBJECT!
HOPE YOU HAD FUN! :-)
