  • Lever.
  • Pulley.
  • Wheel and Axel.
  • Inclined Plane.
  • Screw.
  • Wedge.
NOW IT'S YOUR TURN!!!!! Could you identify examples of the six simple machines in your real life? It is easier than you think. JUST LOOK AROUND,, there are a lot. 


CHECK YOUR LEARNING ABOUT SIMPLE MACHINES WITH THIS TWO ACTIVITIES.
