Generate electricity with airflow—or power the fan and house light using a battery.
The Go Science Classroom Series Windmill Generator is a pre-wired and pre-assembled 2-in-1 school project and educational working model that demonstrates two connected energy-conversion modes using the same DC motor, four-blade propeller and illuminated miniature house.
In Windmill Generator Mode, the model demonstrates the project’s core real-world principle. When the propeller is placed in a suitable stream of air from a sufficiently powerful external fan, it rotates the DC motor shaft. The motor then functions as a small generator, producing electrical output that can illuminate the white LED mounted on the miniature house.
This passive mode allows students to demonstrate the actual sequence:
Airflow → Propeller Rotation → Mechanical Energy → Electrical Generation → House LED
However, practical presentation conditions are not always predictable. During school projects, science exhibitions and classroom demonstrations, students may not have access to a sufficiently powerful external fan. Some exhibition halls may restrict large electrical appliances, provide limited table space or have airflow conditions that are unsuitable for rotating the propeller fast enough to produce a clearly visible LED response.
To help students present the model confidently in these situations, the kit also includes a Battery Fan and House Light Mode. By connecting a 9V battery, students can operate the motorized propeller and illuminate the house LED simultaneously. This mode provides a reliable supporting demonstration of the model’s motor, circuit and lighting functions when suitable external airflow is unavailable.
The battery-powered mode does not replace or represent wind-generated electricity. The passive windmill mode remains the actual airflow-to-electricity demonstration. Instead, the additional battery mode is a practical presentation feature designed to help students keep the model active, visible and easy to explain during school exhibitions, classroom assessments and project presentations.
Together, the two modes give students greater demonstration flexibility:
This dual-mode arrangement helps students move beyond a static display. They can demonstrate the authentic wind-generation concept under suitable airflow and still present a complete working model when exhibition conditions make passive operation difficult.
Suggested for Grades 7–12, the kit can support:
Place the model near a sufficiently powerful external fan and direct the airflow towards the four-blade propeller.
As the propeller rotates:
This mode demonstrates:
Wind Energy → Mechanical Rotation → Electrical Energy → Light Output
The passive demonstration requires adequate airflow, suitable positioning and sufficient propeller speed.
Connect one fresh 9V battery to the supplied battery snap connector.
The battery simultaneously:
This mode demonstrates:
Battery Energy → Electrical Energy → Mechanical Rotation + Light Output
It allows the project to remain demonstrable in classrooms and exhibition halls where a high-speed external fan or suitable wind source may not be available.
The motor, house LED, resistor, battery connector and associated wiring are supplied as an integrated educational model.

The Windmill Generator Kit combines the physical model with guided learning resources that help students understand:
A product-specific digital instruction manual is included through a dedicated manual QR code.
The manual includes:
The manual QR code is separate from the video QR code.
A compatible internet-connected device is required to access the digital resource.
A separate video demonstrates the model, its two operating modes and the expected observations.
The video is available through:
The manual and video use independent QR codes, allowing each learning resource to be accessed separately.
The core electrical circuit is already assembled.
Students do not need to solder the:
The wooden pillar is secured to the base, and the motor and propeller are positioned for direct demonstration.
Students can therefore focus on:
Place the model on a flat, stable and dry surface.
Check that:
Place the model near a sufficiently powerful external fan.
The airflow should reach the propeller directly.
Tilt or rotate the model carefully until the airflow strikes the propeller blades effectively.
As the blades rotate, the motor shaft turns.
When the motor reaches sufficient rotational speed, the generated electrical output may cause the white LED on the house to glow.
Students can note:
Move the model away from the external fan and allow the propeller to stop.
Ensure:
Attach one fresh 9V battery to the battery snap connector.
The battery should:
The propeller functions as an electric fan while the house light illuminates.
Disconnect the battery immediately after completing the demonstration.
Do not leave the battery attached during storage or while the kit is unattended.
A permanent-magnet DC motor can operate in two related ways.
When electrical energy is supplied to it, it functions as a motor and produces rotation.
When its shaft is rotated mechanically, it can produce a small electrical output and function as a generator.
In the passive mode:
The demonstration represents:
Kinetic Energy of Air → Mechanical Energy → Electrical Energy → Light Energy
When a 9V battery is connected:
The demonstration represents:
Chemical Energy in the Battery → Electrical Energy → Mechanical Energy + Light Energy
The motor and LED operate together because they are connected within the integrated circuit.
The white LED requires controlled current during battery-powered operation.
The pre-soldered 22-ohm resistor helps limit current passing through the LED branch of the circuit.
Without suitable current limitation, excess current could damage the LED.
The resistor therefore helps students understand that practical circuits often include components that protect or regulate other components.
Many simple windmill models demonstrate only one operating condition and may depend entirely on strong external airflow.
This 2-in-1 model supports two related demonstrations:
| Mode | Input | Motor function | Visible outputs |
|---|---|---|---|
| Windmill Generator Mode | External airflow | Motor acts as a generator | Propeller rotates and house LED may glow |
| Battery Fan and House Light Mode | 9V battery | Motor acts as an electric motor | Propeller spins and house LED glows |
This allows students to compare:
| Stage | Component | Function |
|---|---|---|
| Air input | External fan or directed airflow | Rotates the propeller in passive mode |
| Mechanical capture | Four-blade propeller | Captures airflow or produces airflow |
| Energy-conversion component | 4.5V DC motor | Operates as a generator or electric motor |
| Electrical protection | 22-ohm resistor | Helps limit current through the house LED |
| Light output | White LED | Provides visible electrical output |
| Powered input | 9V battery and snap connector | Powers the active fan and light mode |
| Structural support | Wooden pillar and anchor screws | Supports the motor and propeller vertically |
| Visual setting | House and grass-covered base | Provides contextual presentation for the demonstration |
In the passive demonstration, the student can follow the complete sequence:
A moving air stream reaches the four-blade propeller.
The propeller captures part of the airflow and rotates.
The rotating shaft drives the DC motor mechanically.
The motor produces a small electrical output.
Current passes through the resistor and LED circuit.
The LED on the house may glow when the generated output is sufficient.
In the active demonstration:
The 9V battery supplies electrical energy.
The DC motor rotates the propeller.
The propeller creates visible rotation and airflow.
The house LED receives current through the protected circuit.
The motorized fan and house light operate together.
Students can perform supervised comparisons such as:
Move the external fan closer to or farther from the propeller.
Observe how the propeller speed and LED response change.
Change the angle between the model and the external fan.
Observe which position produces the best rotation.
Compare different external-fan speed settings.
Record when the LED first begins to glow.
Compare:
Use a fresh battery and observe the fan and LED response.
A weak battery may result in slower rotation or reduced LED brightness.
Observe whether the propeller rotates freely and evenly.
Do not operate a damaged, obstructed or badly misaligned propeller.
The kit supports students in practising:
Students can use the same model to investigate:
The assembled format is suitable for:
The visual model allows students to point to the airflow source, propeller, motor, resistor, LED and battery connector while explaining the complete process.
“This is a 2-in-1 wind turbine generator and motorized house light model. In Windmill Generator Mode, external airflow turns the propeller. The propeller rotates the DC motor shaft, and the motor acts as a small generator. The generated electrical output passes through the circuit and may light the LED on the house. In Battery Fan and House Light Mode, a 9V battery powers the motor and the LED together. The propeller rotates as a fan while the house light glows. The model therefore demonstrates both mechanical-to-electrical and electrical-to-mechanical energy conversion.”
After understanding the model, students may explore more advanced topics such as:
Additional equipment, measurement instruments, components and safety controls would be required for expanded experiments.
Wind turbines use moving air to produce rotational motion.
A DC motor can demonstrate both powered rotation and small-scale generation.
Renewable-energy systems can contribute to broader discussions about electricity generation and community infrastructure.
The house model provides visual context for discussing how generated electricity may supply a load.
Students can discuss how energy is transferred and why losses occur during every conversion stage.
The resistor demonstrates the importance of controlling current through sensitive components.
The Windmill Generator Kit can support:
The project may be discussed in relation to broad educational themes connected with:
The passive mode introduces the concept of electricity generation using airflow and renewable wind energy.
The house-light demonstration can support discussions about sustainable energy systems and community infrastructure.
The model can introduce conversations about renewable-energy technologies and reduced dependence on conventional energy sources.
These are broad educational connections only and do not represent official SDG certification, approval or verified environmental performance.
The Windmill Generator Kit guides students through:
Identify → Position → Generate → Power → Observe → Compare → Troubleshoot → Explain
By the end of the guided activity, students should be better prepared to explain:
| Observation | Possible cause | Corrective check |
|---|---|---|
| Propeller spins but LED does not glow in passive mode | Insufficient airflow, low rotational speed or poor angle | Increase fan speed, move closer and direct airflow towards the blades |
| Propeller does not rotate under external airflow | Airflow is weak, misaligned or obstructed | Reposition the model and ensure the propeller rotates freely |
| LED glows only faintly in passive mode | Generated electrical output is low | Increase propeller speed and improve airflow alignment |
| Neither fan nor LED operates with battery | Weak battery or poor snap connection | Disconnect and reconnect a fresh 9V battery |
| Fan spins but house LED does not glow with battery | Loose circuit connection or LED fault | Disconnect the battery and inspect visible wiring without altering soldered joints |
| LED glows but propeller does not spin with battery | Motor obstruction, loose motor connection or mechanical resistance | Disconnect the battery and check that the propeller rotates freely |
| Wooden pillar feels loose | Bottom anchor screws require tightening | Support the pillar and carefully tighten the screws from beneath the base |
| Propeller vibrates | Misalignment, looseness or blade damage | Disconnect all power and inspect the propeller before reuse |
| Battery connector becomes warm | Short circuit, damaged connector or incorrect use | Disconnect the battery immediately and discontinue use |
| Motor becomes unusually warm | Prolonged operation or obstruction | Disconnect the battery and allow the motor to cool |
Stop using the model if any component becomes excessively hot, damaged, loose, produces an unusual smell or shows signs of electrical failure.
