A simple machine is a stapler.The parts are the the stapler bullets are the wedge that push into anything(e.g:paper) and the top arm of the stapler is the lever as it helps to move the stapler up and down. It makes work easier for us as it can hold paper together so that the paper will not scatter everywhere and it is very light and can carry anywhere(e.g:in your pencil box).
Lever
A lever is made up of Fulcrum,and a board.A lever can lift the load with a lesser effort but it will have to move a longer distance. Such examples of levers is,spoon, Wheelbarrow and many more.
Alarm clock.It has gears that move the 'hands' around.Without it we`ll not know the time!
The object that I have select is wheelbarrow. The simple machine used for it is wheel and axles. It helps us to make our task easier by we can put in things that we neeed to bring to one side to another. It is very useful as it also can carry heavy things too like bricks and broken parts of a bicycles not only that its wheels could even move on hard surface. Wheelbarrows is a cool machine that could carry heavy things like no other.

[Can Opener]
The object i choose is the can opener.
The simple machine of the spinning handle is wheel and axle.
It help usn to open can food easily
Wheel on a car.Wheel and axle help us move heavy object more easily from one place to another
1)A boat propeller.(SCREW)
- is used to rotate to move a boat through water.
#[can opener]#
The can opener is a gear so it helps us to open the can by pressing the handle and turning it around the can.
I choose a doorknob. It is a wheel and axle. The games are also nice and educational.But, there is one game which is quite..erm...scary. The doorknob helps us to open and close doors.
The object that I have chosen is scissors.It is used for cutting things. The simple machine used is lever. It could cut things that is thin like paper.
The ramp is a inclined plane. It helps cars move into the road.
The saw is a wedge. It helps us to cut through objects.
The fishing rod is a third class lever. It helps us catch a fish easily.
The Saw. It is a wedge, it can help cut through wood and cut other hard things. Without the saw, we would be slow in cutting wood.

The object i choose was can opner. It helps to open can.
I choose a screw. A screw is a inclined plane. It helps to hold on things. We use less effort to move things but we have to move a longer distance.
1.a boat propeller.(screw)
it helps us to rotate through the water.
Drill,the simple machine is using the energy from the rotating handle to work the drill.This will
help us to open the can easer.
I am choosing a driller. The srew .
Helps drill a hole
A stabler is made up of 2 different simple machines.The top arm of a stapler is made up by lever and a staple as it pierces paper is Wedge.When we have a lot of paper ,we can use it to stable together.
screw driver,screw,it helps to srew things onto the wall
Watch. it can help us to know what is the time. its machines is gear, if it doesn't have a gear, it will not move.
The object I choose is an axe. The ps to split things apart like wood. It only works when the object is about right-angle to the wedge on the axe. The wood on the axe is a leaver.
Drill-
It has a drill bit that is a screw as it twist and turn to drill a hole.
It has a rotaing handle that act like a gear. This gear transfer energy from the turning motion of the handle.
The handle is a lever. Turning the lever around a fulcrum creates the energy to work the drill.
The object I choose is the bicycle. The simple machines are wheel and axle. We can ride on it and bring it almost everywhere as it is light. It is also a form of exercise.
The axe.The axe is wedge and it help us to chop trees and wood.
Simple machines made our lives simple and easy. For example..the boat propeller is a screw, when you rotate it, it moves the boat through the water.
I think a ramp is a simple machine as it helps us to push heavy things up a higher places without using alot of effort.
