4piece atom and molecular crystal model set including NaCl, diamond, graphite, and C60. Designed for students and teachers, this set makes threedimensional crystal structures easy to see and understand. Key benefits Clarifies abstract concepts: Converts textbook diagrams into tangible 3D models to help students grasp lattice geometry, bonding differences, and spatial arrangement. Supports varied teaching styles: Works for lecture demonstrations, handson lab activities, and selfstudy review. Useful visual comparison: Four distinct structures show ionic lattice, covalent network, layered allotrope, and molecular cage in one set for direct comparison. Studentfriendly handling: Sized for tabletop use and classroom demonstration, suitable for student desks and lab tables. Ready for display or gifting: Appropriate as an educational gift or a demonstration tool for science fairs and displays. Important attributes Function: Educational models for teaching and learning crystal structures and basic solidstate chemistry concepts. Included models: Sodium chloride lattice, diamond lattice, graphite layered structure, and C60 fullerene. Quantity: Four pieces in one set. Intended users: Chemistry students, teachers, tutors, and hobbyists interested in molecular and materials structure. Performance: Designed to make structural features visible and easy to compare during lessons and study sessions. Practical use scenarios Classroom demonstration: Use during a lecture to illustrate the difference between ionic bonding and covalent networks, and to show graphite layer sliding versus diamond rigidity. Study and homework aid: Students use the models to visualize coordination numbers, unit cells, and packing when completing assignments or preparing for exams. Science fair or display: Exhibit the set to explain molecular geometry and material properties to judges and visitors, or include it as part of a handson demonstration station. What makes this set stand out Comprehensive selection: Includes four representative crystal structures in one set so instructors and learners can compare common and advanced examples without assembling multiple kits. Practical for education: Built to be used directly in teaching scenarios from introductory to advanced topics in chemistry and materials science. Contents summary Fourpiece set: NaCl model, diamond model, graphite model, C60 model One set suitable for student use, classroom teaching, and educational gifting This set provides a straightforward, handson way to bring crystal structures into the classroom and into study sessions, helping users visualize and compare fundamental solidstate concepts.
