Simple Machines by: Christina Napolitano Yvette Sarmiento Eufemia N unez
3
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.
4
There are six types of simple machines. wheel and axle pulley incline plane wedges screw lever
5
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
6
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
7
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
8
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
9
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
10
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
11
Two simple machines, make a compound Machine two or more simple machines working together Examples: bike and a car
12
Lesson: Students will have to make a kid inspiration chart then exchange with a partner for assessment.
13
Lesson: Students will have to make a bar graph of how many of each simple machine they found in their group. Pulley6 Wheel and Axel4 Inclined Plane7 Lever2 Wedge1 Screw10
