Instructions:

Prepare the Solar Panel: a. Attach the solar panel to a wooden stand to position it for optimal sunlight exposure.

b. Connect the positive and negative terminals of the solar panel to the corresponding terminals on the DC motor, using wires. Ensure that the polarity is correct to allow the motor to spin in the desired direction.

Attach the Fan Blade: Carefully attach the fan blade to the shaft of the DC motor, ensuring a secure fit. The fan blade should be positioned to create airflow when the motor is activated.

Secure the Components: Arrange the components on the fan handle and secure them with hot glue. Ensure that the solar panel is positioned to receive maximum sunlight while allowing for easy handling.

Test the Solar Powered Fan: Place the DIY solar-powered fan under direct sunlight and observe as the fan blade starts spinning, creating a refreshing breeze.

Discuss STEM Concepts: Take the opportunity to explain how solar panels convert sunlight into electrical energy, which powers the DC motor and drives the fan blade. Discuss basic concepts of renewable energy and sustainability.

Experiment with Design: Encourage your child to experiment with different fan blade designs or materials to observe how they affect the airflow. This allows for creativity and additional learning.

Conclusion: The DIY STEM Solar Powered Fan not only provides a practical application of solar energy but also introduces children to key STEM concepts. This project promotes environmental awareness and encourages a hands-on approach to learning about sustainable technologies. Enjoy the process of creating a functional science toy while exploring the wonders of solar power!
