4-Metal Equal Mass Cylinders Set (Copper, Iron, Aluminum, Zinc)

This four-piece equal mass metal cylinder set includes copper, iron, aluminum, and zinc specimens. Each cylinder has the same 100 g mass and 0.6-inch (16 mm) diameter but varies in length due to the different densities of the metals. The set is accompanied by a complete instruction manual covering density, specific gravity, and specific heat, along with inquiry-based student activities and capture sheets. These cylinders can be used for density investigation, specific gravity, and specific heat experiments across multiple grade levels. Due to the nature of raw metals, some oxidation may occur; simply scuff it off to restore appearance. Expect tolerances in the +/-5% range of stated dimensions.
