Lightweight, durable mountain hydropower station demonstration model designed for middle school geography teaching. Portable and built to retain shape and color over repeated classroom use, the model clarifies landform structure and the surface processes that shape hydropower sites. Key benefits Portable and durable: lightweight construction makes the model easy to carry between classrooms and field sites while resisting deformation and discoloration for a long service life. Clear, realistic surface detail: natural groove texture on the surface highlights ridges, valleys, and channel patterns, making spatial distribution and surface morphology easier to observe and explain. Improves student understanding: concentrates largescale landscape processes into a compact, visible form to help students form accurate concepts of mountain hydropower station structure and related terrain dynamics. Teaching focused: designed specifically for geography instruction in middle school, supporting lesson explanations, demonstrations, and handson activities. Practical uses Classroom demonstration: use during lectures to point out reservoir placement, intake and penstock routes, and surrounding topography while explaining how location and landform affect hydropower design. Group activities and labs: allow student teams to examine features up close, practice labeling components, and discuss how terrain influences water flow and station layout. Teacher preparation and assessment: use the model to design assignments, test student recognition of landform features, and illustrate beforeandafter scenarios when discussing landscape change. Product details Purpose: demonstration model for mountain hydropower station landform structure, intended for middle school geography teaching Surface: clear, natural groove texture for intuitive visualization of terrain and surface morphology processes Durability: lightweight yet long lasting, resists deformation and discoloration under normal educational use Size: 49 cm long x 37 cm wide x 15 cm 19.2 in long x 14.5 in wide x 5.9 in This model provides a practical, easy to handle visual aid to support teaching and learning about mountain hydropower stations and related landform processes.
