3. What are Machines?
A machine is a piece of equipment
with moving parts that does work
when it is given power from
electricity, gasoline, etc.
-Merriam-Webster Dictionary

5. Simple Machines:
• have no or few moving parts
• make work easier
• requires energy to work
• work with a push or a pull
There are 6 kinds of
Simple Machines
1. Inclined Plane
2. Lever
3. Wheel and Axel
4. Pulley
5. Wedge
6. Screw
Simple machines are tools that can make a tough job easier
by letting a person apply less force to move an object.

6. An inclined plane is a slanted surface that connects a
lower level to a higher level helping to move an object up
and down.

Types of Inclined Planes
• Ladder
• Slide
• Ramp
• Stairs

Lever
A lever is a stiff or hard bar that rests on support
called a fulcrum that lifts or moves a load.
Types of Levers
• Scissors
• Seesaw
• Hammer
• Balance
• Catapult

What is a Fulcrum?
Why are they important?
A fulcrum is a point where a lever can turn or balance.
A fulcrum is important because without it the lever wouldn’t
be a lever. It would just be a hard piece of material. The
fulcrum allows the hard piece of material to become a
simple machine. The fulcrum is the brace that allows the
lever to move the object.

A wheel and axle is made up of two parts: the wheel
and the axle. The axle is a rod that goes through the
wheel and allows it to turn. The wheel is circular part
that moves or moves other things.
Types of Wheel and Axle
• Ferris Wheel
• Skateboard
• Gears
• Bicycle
• Pencil Sharpener

10. Home
A wedge is two inclined planes put together back to
back. The two inclined planes then form a sharp
edge. This is a wedge. A wedge is often used to pry
objects or to hold an object in place.
Types of Wedges
• Door Stop
• An Axe
• Knife
• Fork
• Scissors
Wedge

A pulley is a
grooved wheel with
a rope that raises,
lowers, or moves a
load.

A screw is an inclined plane that has been
wrapped around a cylinder which holds
things together or lifts objects.
Types of screws
• Jar Lid
• Screw
• Light Bulb
• Corkscrew
• Vice
Screw

Test Your Knowledge
Know that you know more about Simple Machines let’s test your
knowledge. You will be given 4 different items and will tell what
simple machine is being represented.
Click on the picture to see if your right!!!

14. The dustpan is an example
of an inclined plane. The
inclined plane of the dustpan
allows the dirt to go into the
pan easier. If the dustpan
wasn’t and inclined plane it
would be harder to get the
dust into the pan.

15. The scissors are an
example of 2 different
simple machines. They are
a lever and 2 wedges.
They are a lever because
the fulcrum is where the 2
arms connect and the
levers are the silver parts.
It is also has 2 wedges.
Both of the cutting surfaces
are two inclined planes put
together to form a sharp
edge.

16. This cart is an example
of a wheel and axle. The
wheel and axle of this
cart allows the user to
get the boxes from one
place to another. If you
look between the front
wheels you can see the
bar that is the axle.

Test Your Knowledge

17. A hammer is an example
of a lever. The back of
the hammer would be 2
levers side by side that
allows someone to
remove a nail. You
would put the nail in
between the two levers
and then using the wall
pry the nail out of the
wall.

18. Compound Machines
Compound, or complex, machines are two or more
simple machines working together to make work
easier.
Home
Types of Compound Machines
• Wheel Barrow
• Stapler
• Can Opener
• Scissors
• Dump Truck

19. Rube Goldberg
Who was Rube
Goldberg?
Rube Goldberg was an engineer,
inventor, cartoonist, and sculptor.
What was he
known for?
Rube Goldberg was best know for drawing
cartoon of machines and contraptions. His
cartoons showed simple household items,
connected in funny ways that performed a
simple task.

Now it’s your turn!!
You will be making your own Rube Goldberg Machine in
class. You and a partner will work together using the
materials provided to make your own Rube Goldberg
Machine.
Instructions:
1. Decide what your machine will do
2. Sketch out a design (Show to teacher)
3. Gather materials
4. Begin building your machine
5. TEST, TEST, TEST
6. Present finished project to the class

22. Websites
These websites will provide you with fun ways to learn more
information about machines, both simple and compound. You will also
find one on Rube Goldberg.

• The purpose of this PowerPoint is to inform 3rd grade students about
simple and compound machine. The content is meant to inform
students in a simple, yet creative way. The information being
presented is put into small chunks with videos to add to the
educational experience.
• I feel that the biggest challenge I faced while doing this assignment
was time. I procrastinated, again, and found this assignment to be
more time consuming than I had anticipated. However, I am very
proud of the work that I have accomplished.
• I found my biggest success to be that I incorporated a lot of the tools
that I had learn throughout the semester. I used photo editing, made
my own pictures, used audio and video, and was able to make an
educational and interactive PowerPoint that I will be able to use in the
future.
