Electric fan

The Electric Fan STEM kit offers a practical learning experience that delves into the principles of electromagnetism and aerodynamics. Children assembling this kit will understand how a small electric motor converts electrical energy into mechanical energy to spin a propeller. They'll explore the workings of the motor, learning about the interaction between electric currents and magnetic fields, which is fundamental to the operation of many electrical devices. This hands-on project helps to solidify their grasp of the principles of energy conversion, demonstrating how electrical energy can be harnessed to perform work, in this case, to create airflow.

In addition to the principles of electromagnetism, the kit also provides insights into the design and function of a propeller. As the blades rotate, children will see how they cut through the air, creating a difference in air pressure that results in a cooling breeze. This introduces the basics of blade pitch, angle, and shape, all of which contribute to the fan's ability to move air efficiently. By building and experimenting with the desk fan, students not only learn about the physical principles that underpin everyday appliances but also gain an appreciation for the engineering and design considerations that go into creating functional, effective devices.
