Explore density with real materials The Density Identification Set challenges students to identify unknown materials by measuring mass, calculating density, and comparing results—turning density from a formula into a true investigative process. The set includes 12 solid cylinders, all with the same 1/2" diameter but different lengths and densities, allowing students to focus on density as an intrinsic material property rather than size or shape. Why Teachers Love the Density Identification Set Inquiry-based learning: Students determine material identity through measurement and analysis, not labels. Controlled variables: Uniform diameter keeps comparisons focused on mass, volume, and density. Wide range of materials: Includes copper, brass, pine, rubber, glass, Teflon, aluminum, Delrin®, PVC, nylon, lucite, and oak for meaningful comparison. Classroom-ready storage: Comes with a drilled block that keeps samples organized and easy to manage.
