Durable metal and plastic lever kit designed for scientific and educational use as a lever balance and lever caliper. Combines practical function with an attractive, simple design for classroom, lab, or home use. Key benefits Robust construction: metal components provide strength where needed and plastic parts reduce weight for easier handling and longer service life. Clear function: serves as a lever balance and lever caliper for demonstrations, comparisons, and basic measurements in experiments. Easy to transport and store: disassembles quickly to save space and fit into a kit bag or classroom cupboard. Professional appearance: simple, refined design that suits educational settings and lab benches without unnecessary bulk. Versatile use: suitable for demonstrations, handson experiments, and smallscale measurement tasks across home, school, and laboratory environments. Features and attributes Materials: combination of metal and plastic for durability and practicality. Function: designed to operate as a lever balance and lever caliper for exploring torque, equilibrium, and comparative mass. Portability: components separate for compact storage and convenient carrying. Compatibility: integrates with standard classroom demonstration equipment and common lab setups. Practical applications Classroom physics demonstrations: show torque, fulcrum placement, and mechanical advantage with clear, repeatable setups. Laboratory experiments: use as a lever caliper to compare small masses or to illustrate principles of balance in controlled exercises. Home STEM projects and hobby use: portable design supports handson learning and prototype testing away from the lab bench. Who will find this useful Teachers and educators preparing handson lessons on mechanics. Students conducting experiments or needing a compact tool for demonstrations. Hobbyists and researchers who require a simple, portable lever instrument for comparative measurements. Simple to assemble, easy to store, and built to withstand regular educational use while maintaining a clean, professional look.
