Abstract. Beads and wires are common materials used in jewelry-making, are widely available, and may be used to explore a wide variety of physical properties. Specifically, beads may be used for hardness and density experiments while wires may be used for conductivity and malleability experiments. This experiment may be modified for use in a variety of classroom settings.

Key Words: Laboratories and Demonstrations; general chemistry; non-major laboratories; high school; physical property determination; density; hardness; malleability
