Designed and built a windmill from foam and wood. Tested 4 different blade angles to optimize power generation. Successfully powered an LED light using kinetic energy from the wind.
Built a truss bridge with engineered supports. Used structural analysis to predict failure point. Tested to actual failure and documented load capacity. Created labeled diagrams of stress points.
Documented 4 design iterations with detailed sketches, precise measurements, and performance data. Each iteration informed the next. Created data tables comparing efficiency at different angles.
Created a presentation explaining energy transfer concepts: kinetic, potential, generator, and efficiency. Used proper scientific vocabulary and demonstrated understanding of the engineering principles.
