People are growing increasingly interested in environmentally friendly inventions as global warming becomes a popular issue. The wind turbine is without a doubt one of the most efficient ways to create a green energy source.
For school science projects, building a wind turbine might be a good choice. Don’t be alarmed; making one out of cardboard and a DC motor isn’t difficult. You can build a wind turbine in a short amount of time for your forthcoming school project and make a distinctive and clever impression on visitors.
Building a Wind Turbine for a School Project
1. We’ll start by making the rotor. To accomplish so, cut four 3cm diameter circular cardboard pieces. Glue and adhere to all of them together. All four parts must be used to form a thick circle. As a result, one piece must adhere to the other on the top.
2. Glue it to the side of that enormous circle of cardboard and cover it in thin paper. Make sure you trim the paper to fit the circle’s diameter.
It’s time to start working on the blades. Cut four little pieces of cardboard from the cardboard. All four pieces measure 8cm x 2.5cm in size.
The round cardboard piece will be glued with these four components. As a result, one end of these parts must be rounded to fit exactly into the circle-shaped rotor.
Now bend all four sections slightly from the center, making them slightly round shaped like original turbine blades. Glue them all on the rotor and let them dry.
3. Now it’s time to build the tower. Take a 30cm by 12cm piece of cardboard paper and cut it into tiny strips. Wrap the paper around a pen or a round stick. Pull the pen out and glue the end of the paper.
4. Take the DC motor you gathered before. Wrap two pieces of cardboard around the engine. The first component is used to mount the motor, while the second is used to surround the motor from top to bottom. Ensure that the motor’s pointed end remains entirely outside of the cardboard pieces.
Take the four-bladed rotor and drill a tiny hole in the center. The motor’s pointed end must be inserted into this hole.
5. Using a shot pistol, connect the negative and positive wires to the motor. Make sure the cables are long enough to connect an LED light on the opposite end.
Attach the tower to the bottom section of the cardboard piece that holds the motor using adhesive. Allow 15 minutes for drying.
6. Once the tower is securely attached to the turbine’s upper section, go on to the base. Make a square piece of cardboard with a hole large enough to attach the bottom of the tower to it. Apply glue to the bottom of the tower and secure it to the base you’ve just finished.
7. The wind turbine is now complete. Now you must construct a cardboard home that will house the LED light. The size of the residence is entirely up to you.
Make the house’s walls out of four pieces of cardboard. On the broader one, which will be on the front side of the home, cut three windows and just one door. The final piece, which will be on the house’s back wall, will have no window or door cutouts at all.
To create the house’s walls, glue all four parts together and attach them to each other. Cut a roof out of another piece of cardboard, but don’t attach it to the walls yet.
8. Take the LED light and correctly connect the wires. With a piece of tape, secure the light at the front window of the house. To link the roof to the four walls, glue the tops of the four walls together. You may use a flat cardboard piece for the roof or two pieces of cardboard to construct a triangular shape for the roof.
9. Now, take a plywood board and glue the tower foundation that will hold the complete turbine together. Also, glue the home to the plywood. Connect the wires from the motor and the LED light together.
10. Finally, position a table fan far enough away from the turbine to keep it safe. When you turn on the fan, the blades will spin due to the breeze. When there is enough wind to power the LED light, it will turn on.
That concludes our discussion. For your school project, you successfully built a basic functional home turbine. This project’s supplies are widely available and inexpensive.
Is your turbine already lighting up your “house”?
