This threedimensional cell membrane model is designed as a practical teaching aid for middle school, school, and junior college biology classes. It clearly illustrates the structure seen under electron microscopy, including the threelayer arrangement and the positioning of protein and lipid molecules, making abstract concepts easier to visualize and teach. Key benefits Improves comprehension: Makes the threelayer membrane structure and the arrangement of proteins and lipids easy to see and understand. Supports lesson plans: Ideal for demonstrations during lectures, lab sessions, and group study to reinforce textbook diagrams and microscope observations. Classroom ready size: Compact dimensions allow easy handling, table display, and storage without occupying excessive space. Versatile use: Suitable as a handson teaching instrument or a display model for classroom walls, lab benches, or biology exhibits. Features Educational focus: Specifically built to teach the cell membrane structure as observed under electron microscopy, helping students connect microscopic images to a tangible model. Detailed design: Delicate, lifelike details highlight the threelayer structure and the arrangement of lipid and protein components. Size: Measures 24 cm x 19 cm x 12 cm for convenient demonstration and storage. Durable and transportable: Sized for easy carrying between classrooms and simple placement on demonstration tables. Typical use scenarios Classroom demonstration: Use the model during a lecture on membrane structure to point out the threelayer appearance and locations of integral and peripheral proteins and lipid molecules. Lab preparation and review: Provide students a tactile reference before or after microscopy sessions to compare electron micrographs with the model. Display and outreach: Place the model on a lab bench or in a school display case to reinforce curriculum topics and support student study. This model provides a clear, reliable visual reference for teachers and students studying cell membranes, helping bridge the gap between abstract images and concrete understanding.
