This PowerPoint presentation introduces 3rd grade students to simple machines. It defines six simple machines - the inclined plane, lever, pulley, screw, wedge, and wheel and axle. For each machine it provides an example, definition, and photos of the machine found on a playground. The presentation concludes that simple machines make work easier, have few moving parts, and can be combined to form more complex machines. It aims to teach students to identify the six simple machines and their functions.

1. Simple Machines
By: Blair Thallmayer
Grade: 3

2. Bill Nye The Science Guy

3. Standards & Objectives
 3.1.4 A Know that natural and human-made
objects are made up of parts.
 Identify system parts that are natural and human-made
(e.g., ball point pen, simple electrical circuits, plant
anatomy).
 Objective:
 After completing the PowerPoint presentation and 3
activities, the learner will identify the six simple
machines and their functions with at least 90%
accuracy.

4. Introduction
Simple machines make people’s live easier.
All the force needed to make simple
machines work comes from people.
Every simple machine picture in this
presentation was found on the playground.
Look around your house and school and you
might find some simple machines!!!

5. Types of Simple Machines
Inclined Planes
Levers
Pulleys
Screws
Wedges
Wheels and Axles

6. Inclined Plane
 An inclined plane is a flat surface that is higher on
one end.

7. Inclined Plane
 All inclined plans can
help people gain speed
going down it. It helps
people because a roof
slant prevents the
heavy weight of snow
and rain from caving in
the roof. Have you ever
seen a ramp? It is an
inclined plane.

8. Inclined Plane
We found some inclined planes on the playground
Slant on a roof
Slide
Ramp

9. Levers
 A lever is a simple machine that has fulcrum or a stationary
point. A lever needs a kind of force for it to work. The force is
also known as the effort.

10. Levers
 There are plenty of
places in the school
where you could find
levers. Here are
some examples: the
playground, gym, in
the first grade
classroom, in the
kindergarten, and lots
more!

11. Levers
 A see saw is a lever,  A swing is a lever.
it has a fulcrum in the The swing chains
center.
connect to the
fulcrum, the top bar

12. Pulleys
 A pulley is something that
pulls objects up, down
and sideways in the order
to make life easier.
Pulleys hoist things with
less muscle power.

13. Pulleys
 Wheels are in
pulleys!
 The only pulley we
found on the
playground is the flag
pole. It is used for
raising the flag up
and down.

14. Screws
 A screw is
an inclined
plane that
winds
around
itself.

15. Screws
Screws help us to connect two objects together.

16. Screws
A few parts of these objects are screws:
Water Faucet
Clocks
Light bulbs Jars

17. Wedges
 A wedge is a simple machine used to push two
objects apart.

18. Wedges
 There are a lot of Shovel
wedges! Here are
some examples:
Fork &
Knife
Axe
Scissor
Saw Hammer Can Opener

19. Wheels and Axles
 Wheels help people get around faster. Axles help
the wheel turn.

20. Wheels and Axles
Here are some
things that need a Car
wheel and axle to
work.
Wheelbarrow
Skateboard
Motorcycle Roller skates Bike Scooter

21. Activity #1
Sunken Millions
Simple Machines
Mrs. Price
Grade 3

22. Activity #2
 Use the link below to
 Review the Essence of Simple Machines
 Find the Simple Machines
 Putting Simple Machines to Work
Cosi- Simple Machines.mht

23. Activity #3
 Compound Machines
 Find as many simple machines as you can in the bicycle
below. Circle each part and label it.

24. Summary
Inclined Makes it easier to move objects upward; a
Plane longer path, but easier lifting
Helps lift heavy weights
Lever
using longer distances
Pulley Makes lifting heavy weights easier
by redirecting force
Screw Turns rotation into lengthwise movement
Wedge Pushes material apart, cuts
Wheel Makes it easy to move things
and Axle by rolling them, and reducing friction

25. Conclusion
 Basic Types
 Designed to make work
 Few or moving parts
 Combine to form complex machines
