Windmill Project for Kids Explanation

The Working Model of Windmill Project is a simple yet engaging science project that students frequently do in exhibitions. Windmills are devices that use rotation to transform wind energy into workable energy. Windmill blades typically rotate in a clockwise manner. The goal of this windmill project is to teach students about energy transfer from one form to another. A windmill’s rotation frequently powers a motor or generator, which produces electricity or mechanical work.

Windmill Project

The use of wind power to convert an object’s rotation into productive energy and work extends originally from 1st century Greece, and wind wheels were extensively recorded in 7th century Persia. Daniel Halladay of the United States designed the first proper windmill in 1854. Windmills are classified into two categories based on their axis of rotation:

  • Windmills with a vertical axis
  • Windmills with a horizontal axis

Horizontal axis windmills are classified into four types: post mills, smock mills, tower mills, and fan mills. A windmill model is an excellent craft science project for students. In the following section, we will learn more about how to construct the windmill project.

The Working Principle of Windmill Project for Kids – A windmill is a large structure with sails interconnected by a fixed spinning motor. The spinning gear turns these blades, which assist in converting wind kinetic energy into electricity. When the wind blows across the windmill’s moving blades, the generator connected to the windmill generates power. And that energy/electricity can be used in any type of work.

Windmill Science Project

Windmills are an excellent example of a wheel-and-axle machine. The wheel is able to spin on an axis, using the wind’s energy to propel it by using sails, or shapes that can capture the wind. Science projects, as well as other types of projects, help youngsters to learn while creating something new. When constructing a windmill project, students may make the unintentional mistake of connecting a motor fixed with a fan to a battery cell, resulting in a fan that runs on a battery rather than a windmill. Read the windmill science project instructions properly while making the model.

Materials needed for Windmill Science Project

  • Plastic fan motor (6 volts or higher)
  • LED Resistor
  • Motor mounting pole made of wood
  • Board of wood
  • Wire for connecting
  • Cello tape

Windmill Project for Kids Explanation -_3.1


Step 1: At first attach the motor to the wooden pole or whatever material you’re using to build the pole.
Step 2: Check that the motor is securely fastened using cello tape.
Step 3: Next, secure the pole to the wooden plank or other base support material. (We chose the ply board because it is durable and readily accessible)
Step 4: Remove the insulation from the connected wire and cut it into two pieces.
Step 5: Attach the resistor to the motor’s terminal one of the cables that connect to the resistor and the additional wire to the terminal.
Step 6: Mount LED terminals to the ends of the connected wire.


You have successfully completed your windmill project. Simply rotate the fan at a high speed to generate electricity. Then observe if the LED illuminates.

Windmill Project Explanation

Let us analyze the logic behind windmill project electricity generation. here we give detailed explanation of windmill project

  • Because of the aerodynamic airfoil design, the blades feel lift when the wind goes across them. The blades rotate and begin to rotate as a result of the lift produced.
  • When the wind direction changes, the yaw unit points it in the direction of the incoming wind. The rotation of the blades is conveyed to the generator, which generates energy, via the gear train and couplings.
  • The electricity is then routed through wires to storage batteries or right into the power grid.

How to Increase Windmill Speed?

We can attach a gearbox before the generator in order to achieve a fast speed ratio of 1: 90 (cut-off speed of 80 kmph). A brake is also installed in a nacelle to assist with wind arrest during windy circumstances. The generated electricity is then transported to the transformer located at the windmill’s base.

Windmill Model Science Project

let’s understand the utilization of Windmills. The primary function of a windmill is to transform wind energy into electrical energy, and once this energy is obtained, it is used in the following ways:

  • For groundwater pumping.
  • Timber saw-milling
  • Grain milling
  • Drainage-pumping
  • Extraction of oil from seeds
  • Machining
  • Commodity processing includes –
  • Tobacco
  • Cocoa Dye
  • Stock-watering
  • Paints and spices
