This 3D wind direction indicator model is a handson STEM kit designed for children to assemble and use for basic wind measurement. Made from durable PP material, the kit combines practical construction with a clear demonstration of wind direction and related scientific principles. Key benefits Teaches core concepts: Assembly and operation illustrate how a wind vane detects wind direction and how moving parts interact. Encourages active learning: DIY construction develops fine motor skills, problem solving, and spatial reasoning through stepbystep assembly and disassembly. Ready for classroom or home: Compact and straightforward to use for group activities, individual learning, or guided lessons. Clear function: After assembly the model indicates wind direction and can be used to compare wind patterns over time. Main features Material: Constructed from polypropylene (PP) for a lightweight, rigid model suitable for repeated assembly. Function: Wind direction indicator designed for practical wind measurement demonstrations. Target age: Recommended for children aged 7 to 14, ideal for upper elementary and middle school learners. Educational focus: Designed as a science experiment and STEM education toy to help learners understand scientific principles and build practical skills. Practical uses and scenarios Classroom lab activity: Use the kit during a weather unit to demonstrate wind direction, record observations, and link results to local weather patterns. Home STEM project: Parents and children can assemble the model together, then place it outdoors to observe changes in wind direction during play or daily routines. Science fair or presentation: Build and display the assembled wind vane as a simple experiment to explain how wind direction is measured and to present recorded data. Who should choose this product Teachers seeking a simple, handson tool for weather and physics lessons. Parents and caregivers looking for an educational gift for children aged 7 to 14. Students preparing for science projects who need a tangible model to demonstrate wind measurement principles. Contents and expectations DIY assembly kit for a 3D wind vane model made of PP material. Intended for learning through construction and observation rather than professional environmental monitoring. This wind vane model offers a practical, educational way to explore wind direction and basic meteorological concepts while building handson skills.
