This STEM science kit set includes eight complete electric circuit building kits designed for hands-on classroom learning and group activities. Each kit contains all necessary components to construct a working fan, including a motor, wires, battery holder, fan blade, and switch, all housed in a sturdy plastic casing. The materials are durable and safe for children aged 7 and up, with rounded edges and non-toxic components. The kits are pre-sorted and packaged individually, allowing for easy distribution in a classroom or party setting. The instructions are straightforward and visual, enabling students to assemble the circuit with minimal adult assistance. The kits focus on fundamental electrical concepts such as open/closed circuits, polarity, and energy transfer, making them suitable for 2nd, 4th, and 5th grade STEM curriculums. The components are reliably constructed with metal contacts and insulated wiring to ensure consistent conductivity and long-term use. The fan operates smoothly once assembled, providing a clear demonstration of how electrical energy converts into mechanical motion. These kits are an affordable, bulk option for teachers, homeschool educators, or event organizers seeking engaging, budget-friendly STEM activities. The value is excellent for group projects, science fairs, or party favors, offering a low-cost entry point into electrical engineering concepts without sacrificing quality. The kits are compact and lightweight, making them easy to store and transport. They are designed to be reusable if handled carefully, though replacement batteries are required each time.

This set provides a practical, educational, and economical way to introduce basic circuitry to young learners.
