A grant from 3M funded a multi-state 4H Power of Wind project that uses inquiry-based learning to teach youth about wind power and developing STEM competencies. Through hands-on experience with building wind turbines, youth discover how turbines generate electricity by asking questions, using tools, constructing, predicting, testing, observing, measuring, recording data, troubleshooting, comparing results, and optimizing - with adults acting as facilitators rather than directly teaching knowledge. The project trains youth to generate their own understanding through active exploration and questioning.
