This Specific Gravity and Essential Components Kit includes a Newton/gram scale dynamometer (1N/100g, 0.02N/2g graduations), an aluminum displacement vessel (130mm height, 110mm diameter, 30mm spout), an aluminum catch bucket (4-inch diameter, 3.15 inches height with handle), and three 0.75-inch metal cubes with hooks in iron, copper, and aluminum. The kit provides the instrumental tools needed to measure specific gravity of metals. A ring stand (such as Eisco MTST1) and digital balance are recommended but not included. Instructions are not included. Suitable for physics classrooms studying density, buoyancy, and Archimedes' principle.
