Transcript of "My Presentation On Simple Machines"

  1. 1. Simple Machines By: Blair Thallmayer Grade: 3
  2. 2. Bill Nye The Science Guy
  3. 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. 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. 5. Types of Simple Machines Inclined Planes Levers Pulleys Screws Wedges Wheels and Axles
  6. 6. Inclined Plane  An inclined plane is a flat surface that is higher on one end.
  7. 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. 8. Inclined Plane We found some inclined planes on the playground Slant on a roof Slide Ramp
  9. 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. 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. 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. 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. 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. 14. Screws  A screw is an inclined plane that winds around itself.
  15. 15. Screws Screws help us to connect two objects together.
  16. 16. Screws A few parts of these objects are screws: Water Faucet Clocks Light bulbs Jars
  17. 17. Wedges  A wedge is a simple machine used to push two objects apart.
  18. 18. Wedges  There are a lot of Shovel wedges! Here are some examples: Fork & Knife Axe Scissor Saw Hammer Can Opener
  19. 19. Wheels and Axles  Wheels help people get around faster. Axles help the wheel turn.
  20. 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. 21. Activity #1 Sunken Millions Simple Machines Mrs. Price Grade 3
  22. 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. 23. Activity #3  Compound Machines  Find as many simple machines as you can in the bicycle below. Circle each part and label it.
  24. 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. 25. Conclusion  Basic Types  Designed to make work  Few or moving parts  Combine to form complex machines
