Product overview This enlarged chromosome model is a durable teaching aid made from PVC with careful handmade construction and precise workmanship. It presents chromosome structure in a clear, observable format suitable for classroom and exhibition use. Key benefits Clear visualization: The enlarged scale exposes chromosomal features for intuitive observation and easier explanation during lessons. Durable construction: PVC material and solid build quality support repeated classroom handling and display. Ready for teaching: Designed specifically as a didactic model to support biology, anatomy, medicine, and physiology instruction. Accurate reference: Includes representation of chromatin behavior, reflecting how genetic material condenses and stains in typical laboratory preparation. Important specifications Material: PVC Construction: Handmade, precision finished Size: 13 x 5 x 30 cm Function: Educational chromosome model for observation and demonstration How this model solves teaching problems Makes microscopic structure accessible: Enlarged details let students observe features that are not visible under casual microscopy, improving comprehension of chromosomal form and organization. Supports diverse lesson formats: Useful for lectures, handson group study, and visual reinforcement of textbook concepts. Durable for repeated use: Robust materials and workmanship reduce the need for frequent replacement of demonstration aids. Practical use scenarios Middle school biology class: Use during units on cell division and genetics to show how chromatin condenses into chromosomes and to illustrate chromosomal parts. Laboratory demonstration: Combine with microscope slides and staining discussions to compare real specimens with the enlarged model during lab sessions. School or research exhibition: Display as a clear, durable example of chromosome structure for fairs, open days, or departmental demonstrations. What you get A handmade PVC chromosome model sized 13 x 5 x 30 cm that highlights chromatin condensation and chromosomal form, intended for teaching, learning, and exhibition purposes.
