Simple Machines by:
Christina NapolitanoYvette SarmientoEufemia Nunez
What is a Simple Machine? A simple machine has
few or no moving parts.
Simple machines make work easier by changing the amount or the direction of the force used to do work.
There are six types of simple machines.
wheel and axlepulley incline planewedgesscrew lever
Wheel and Axle
a wheel that turns on a post to help move things quickly and easily
Gears are a form of wheels and axles
Examples: doorknob, steering wheel, and a screwdriver
Pulley made of rope and string
wound around a reel to change the direction of a force.
A pulley needs a rope, chain or belt around the groove to make it do work
Examples: crane, fishing pole, clothes line, and a flagpole
Inclined Plane An inclined plane is
a flat surface that is higher on one end
Inclined planes make the work of moving things easier
Examples: ramp, and stairs
Wedge two inclined planes
together used to raise an object or split an object.
Wedges are used to split things.
Examples: knife, and an ax
Screws an inclined plane
wrapped around a pole or shaft that is used to hold materials together or drill holes
The inclined plane allows the screw to move itself when rotated.
Examples: drill bit, and screws
Lever made of a board or
bar set on top of a fulcrum.
it is used to lift weight
Examples: seesaw, crowbar, baseball bat, and a rake
Two simple machines, make a compound Machine two or more simple
machines working together
Examples: bike and a car
Lesson: Students will have to make a kid inspiration chart then exchange with a partner for assessment.
Lesson: Students will have to make a bar graph of how many of each simple machine they found in their group.
