6-5.7 Explain how the design of
 simple machines (including
 levers, pulleys, and inclined
 planes) helps reduce the
 amount of force required to
 do work.
A simple machine is a
machine that helps you
do work by changing
the amount or direction
of the force you apply.
At the end of this activity:


You will write a paragraph
 that describes and gives
 examples of the 6 simple
 machines.
Let‟s Learn Together: Gallery Walk
 Rules
   Stay with your group.
   Do NOT leave before time
    is called
   Do not linger at a site after
    time is called
   Use your “secret voices”
   Copy down notes until time
    is called.
   If you finish early, do not
    leave your area or speak
    louder than a whisper!

The Inclined Plane
An inclined plane is a flat
 surface that is higher on one
 end. You can use this machine
 to move an object to a lower
 or higher place.
Inclined planes make the work
 of moving things easier. You
 would need less energy and
 force to move objects with an
 inclined plane.
The Inclined Plane

Examples of Inclined
 Planes:
Ramp
Slanted Road
Path up a Hill
Slide
The Screw

A screw is a simple machine that
 is made from another simple
 machine. It is actually an inclined
 plane that winds around itself.
A screw has ridges and is not
 smooth like a nail. Some screws
 are used to lower and raise
 things. They are also used to
 hold objects together.
The Screw
Examples of the screw:
Jar Lids
Light Bulbs
Stools
Clamps
Jacks
Wrenches
Key Rings
Spiral Staircase
Lever
A lever is a board or bar that
 rests on a turning point. This
 turning point is called the
 fulcrum.
An object that a lever moves is
 called the load. The closer the
 object is to the fulcrum, the
 easier it is to move.
Lever
Examples of the lever:
A hammer is a lever
 when it is used to pull a
 nail out of a piece of
 wood.
Bottle openers
Crow bars
Pulley
This simple machine is made up of a
 wheel and a rope. The rope fits on
 the groove of the wheel.
One part of the rope is attached to the
 load. When you pull on one side of
 the pulley, the wheel turns and the
 load will move.
Pulleys let you move loads up, down,
 or sideways. Pulleys are good for
 moving objects to hard to reach
 places. It also makes the work of
 moving heavy loads a lot easier.
Pulley
Examples of where pulleys
  can be used:
 Flag Poles
 Clothes Lines
 Sailboat
 Blinds
 Crane
Wheel and Axle
You have probably seen a
 wheel and axle on a car. The
 axle turns when you put force
 on the wheel.
The axle is a rod that goes
 through the wheel. This lets
 the wheel turn. It is easy to
 move things from place to
 place with wheels and axles.
Wheel and Axle
Examples of Wheels and
 Axles:
Cars
Roller Skates
Wagons
Door Knobs
Gears in Watches, Clocks,
 and Bicycles
Wedge
A wedge is a simple
 machine used to push two
 objects apart. A wedge is
 made up of two inclined
 planes. These planes meet
 and form a sharp
 edge. This edge can split
 things apart.
Wedge
Examples of wedges:
Knives
Axes
Forks
Nails

6-5.7 Explain how the
 design of simple machines
 (including levers, pulleys,
 and inclined planes) helps
 reduce the amount of force
 required to do work
Levers


A ___________________ is a
 rigid bar or board that is free to
 move around a fixed point called a
 ________________.
A lever can be designed to reduce force
 required to lift an object in two ways:
   By ______________________ the distance
    from the ____________ to the point where
    the effort force is applied
   By _____________________ the distance
    the ____________ is from the fulcrum
 Is it easier to lift the box of books when the
  fulcrum is in the center of the board, or when the
  fulcrum is at the end of the board closest to the
  box?

 Is it easier to lift the box of books when you
  apply a force on the effort arm near the fulcrum,
  or far away from the fulcrum?

 Name one way you could
change this lever to reduce
the effort force required to lift
the load.
Final Key Point


By increasing the distance
 the effort force moves
 relative to the distance the
 weight moves, a lever can
 reduce the effort force
 needed to lift an object.

SC 6 5.7 simple machines-powerpoint

  • 1. Just Do It • What is the purpose of a ramp? • You’re nailing a nail into a big board, but the nail bends. How will you remove it from the board? • What do an axe, a knife, and a fork all have in common?
  • 2. Just Do It: Copy This Table Simple Purpose and Notes Examples Machine Inclined Plane Lever Pulley Wedge Wheel and Axle Screw
  • 3. Standard 6-5.7 Explain how the design of simple machines (including levers, pulleys, and inclined planes) helps reduce the amount of force required to do work.
  • 4. A simple machine is a machine that helps you do work by changing the amount or direction of the force you apply.
  • 5. At the end of this activity: You will write a paragraph that describes and gives examples of the 6 simple machines.
  • 6. Let‟s Learn Together: Gallery Walk  Rules  Stay with your group.  Do NOT leave before time is called  Do not linger at a site after time is called  Use your “secret voices”  Copy down notes until time is called.  If you finish early, do not leave your area or speak louder than a whisper!
  • 7.
  • 8. The 6 Simple Machines Inclined plane Wedge Lever screw pulley Wheel & Axle
  • 9. Make Notes! Print a copy of the data sheet for notes on this presentation by clicking the pencil below.
  • 10. The Inclined Plane An inclined plane is a flat surface that is higher on one end. You can use this machine to move an object to a lower or higher place. Inclined planes make the work of moving things easier. You would need less energy and force to move objects with an inclined plane.
  • 11. The Inclined Plane Examples of Inclined Planes: Ramp Slanted Road Path up a Hill Slide
  • 12. The Screw A screw is a simple machine that is made from another simple machine. It is actually an inclined plane that winds around itself. A screw has ridges and is not smooth like a nail. Some screws are used to lower and raise things. They are also used to hold objects together.
  • 13. The Screw Examples of the screw: Jar Lids Light Bulbs Stools Clamps Jacks Wrenches Key Rings Spiral Staircase
  • 14. Lever A lever is a board or bar that rests on a turning point. This turning point is called the fulcrum. An object that a lever moves is called the load. The closer the object is to the fulcrum, the easier it is to move.
  • 15. Lever Examples of the lever: A hammer is a lever when it is used to pull a nail out of a piece of wood. Bottle openers Crow bars
  • 16. Pulley This simple machine is made up of a wheel and a rope. The rope fits on the groove of the wheel. One part of the rope is attached to the load. When you pull on one side of the pulley, the wheel turns and the load will move. Pulleys let you move loads up, down, or sideways. Pulleys are good for moving objects to hard to reach places. It also makes the work of moving heavy loads a lot easier.
  • 17. Pulley Examples of where pulleys can be used:  Flag Poles  Clothes Lines  Sailboat  Blinds  Crane
  • 18. Wheel and Axle You have probably seen a wheel and axle on a car. The axle turns when you put force on the wheel. The axle is a rod that goes through the wheel. This lets the wheel turn. It is easy to move things from place to place with wheels and axles.
  • 19. Wheel and Axle Examples of Wheels and Axles: Cars Roller Skates Wagons Door Knobs Gears in Watches, Clocks, and Bicycles
  • 20. Wedge A wedge is a simple machine used to push two objects apart. A wedge is made up of two inclined planes. These planes meet and form a sharp edge. This edge can split things apart.
  • 22. Resources Simple Machine Quiz InventorsToolbox: The Elements of Machines Simple Machine Learning Site Simple Machines
  • 23. Exit Slip: Writing Assignment Choose one of the simple machines. Write a paragraph describing it and giving examples.
  • 24. Just Do It Ms. Moye tells you that she would like a 3 page reading report in her class, and it is due in 3 weeks. Mr. Hilton tells you he also wants a 3 page reading report for his class, but it is due tomorrow. Which assignment is easier to complete? Why?  Bonus: What is the definition of a simple machine?
  • 25. Review What are the 6 types of simple machines? Can you name at least one example of each?
  • 26. Simple machines make work easier by spreading it out!

  • 29.
  • 30. Three Types of Pulleys  Fixed pulley: a pulley that is attached to a load. It only changes the direction of the effort  Moveable pulley: a pulley that moves with the object being moved. The effort required to lift the load is cut in half.  Block and Tackle: a combination of pulleys
  • 31. What kind of Pulley?
  • 32. What kind of Pulley?

  • 35.
  • 36.
  • 37. Where is the Fulcrum?
