Practical teaching aid: an educational internship kit for teaching science subjects and activities, includes a special grid for preserving mulberry leaves used to rear caterpillars. User friendly handling: combined feeding area with convenient cleaning options; dedicated space for cocoon formation; easy maintenance that is accessible to all user groups. Space saving innovation: combines function and aesthetics with a playful interior design and stackable structure that creates a miniature landscape, ideal for silkworm breeding enthusiasts with limited space. Improved air system: ventilation holes optimize air exchange in a safe, environmentally friendly environment; odor safety and temperaturemoisture regulation through feedgrade materials to support healthy silkworm development. Classroom use scenario: ideal for handson biology lessons to observe the silkworm lifecycle, from larvae to cocoon, while learning leaf preservation and rearing practices. Home or hobby use scenario: compact, lowmaintenance setup for silkworm rearing in limited spaces, suitable for individuals or families pursuing a smallscale project. Afterschool or club use scenario: practical demonstration of integrated design, observation, and maintenance in educational programs and science clubs.
