Working Model of the Windmill Summery: In this article you will learn how to make working model of the windmill with using household material like cardboard paper cups etc, this projects can be demonstrate in science fair or science exhibition. Windmill or wind turbine is one of the best methods to transform wind energy into electrical energy.
This project is recommended for Grade or Class: 1 to 5
Windmill Project from Cardboard: A simple Windmill or wind turbine can be made by using simple household things to understand the aerodynamics and function of wind mill.
Cardboard sheets of 9×9 and 6×6 square inch are required for making of blades and base of wind mill respectively.
Stand of the wind mill is made with disposable cups and blades are attached to it.
Round sticks are used to attach blades with stand.
Take card board piece of 9×9 sq. inch and make the diagonals to the square sheet, take point of intersection of diagonals as a center of circle and make a circle with radius 2.5 cm.
In the same method, make 4 blades.
Making of blades Wind Mill
Cut the blades along the mark with the help of scissor.
At the center of the blades, make a small hole and fix the round stick with the help of paper tape.
At the inside edges, make a cut of approximately 1 cm vertically and slightly tilt the blades to give them aerodynamic shape so that they can move with the wind
Join the 2 disposable cups base to base with the help of paper tape, then join another cup head to head with any of the cup, join the head of another cup with the cardboard base of 6 sq. inch with the help of scotch tape or paper tape.
Join two more disposable cups head to head with tape and make holes in the center of the cup’s base so the stick can pass through it
Join them to the tower in T-shape.
Cut a small circle of cardboard sheet and make a hole in it. Pass it through the stick and join with the help of tape, it will act as a stopper.
Make two holes oppositely near the upper end of a disposable cup with the help of compass. Tie it with a piece of thread approximately 1 ft long.
Working Model of Windmill in action
Check the wind mill working by using an air dryer or blower.
