Key benefits Makes wind power concepts visible: a miniature wind model demonstrates airflow and turbine blade motion so students can see how wind energy is converted to rotation. Immediate visual feedback: an integrated LED lights up when the blades rotate, giving clear, realtime confirmation of airflow and performance during experiments. Simple, portable demonstration tool: the compact build fits on a classroom desk or in a study area, making demonstrations and handson learning easy to set up and move. What it does and why you need it Demonstrates wind power flow in a tangible way, turning abstract concepts into observable motion. Solves the problem of unclear student understanding by providing a visible, working example that complements lectures, textbooks, and diagrams. Encourages active investigation of renewable energy principles by offering a loweffort, repeatable experiment platform. Key features and attributes Function: miniature wind turbine demonstration that shows blade rotation driven by airflow and triggers an LED indicator during operation. Size and form factor: compact, desktopfriendly construction suitable for classroom demos, lab tables, or individual study spaces. Performance: responsive blade rotation with LED feedback to indicate when sufficient airflow is present. Compatibility and use: designed for educational settings and smallscale experiments; easily integrated into lesson plans, lab activities, or projects. Educational value: supports exploration of renewable energy concepts, observation, and hypothesis testing without complex setup. Typical use scenarios Classroom demonstration: a teacher uses the model on a desk to show students how wind causes turbine blades to rotate and how that motion can be detected visually. Student experiment or science fair: a student includes the device in a project to measure and report how different airflow conditions affect blade speed and LED activation. Independent study or hobby projects: individuals use it at home to explore basic principles of airflow, energy conversion, and renewable power in a handson way. What to expect in practice Quick setup and immediate results for airflow experiments and demonstrations. Clear visual indication of blade movement via LED, useful for group observation and documentation. Portable, practical sizing that supports repeated classroom use and easy storage between lessons. Suitable for educators, students, and anyone exploring renewable energy basics who needs a straightforward, observable demonstration of winddriven rotation and LED feedback.
