Density Cube Set, 9 pcs - Includes Brass, Iron, Copper, Aluminum, Hardwood, Softwood, Nylon, PVC, Acrylic

This 9 piece kit includes a variety of materials in the form of 1" cubes. Materials included - brass, iron, copper, aluminum, hardwood, softwood, nylon, PVC and acrylic. Set includes a wooden storage box with foam cutouts for each cube. Excellent for physics classrooms.

The Eisco Labs Density Investigation series is intended to help learners become familiar with appearance, feel, texture, hardness and density of a range of common substances in addition to providing them the tools to identify and figure out mass, understand the relationship between mass, volume & density, to understand specific heat and specific gravity and provide them with quality introductory physics and chemistry concepts. The included sets offer a wide range of educational applications for all grade levels, including density investigation, specific heat and specific gravity exploration. Set includes a complete manual that describes the basics of density, mass and volume, and instructions for making calculations. Required materials (NOT included): Weight device capable of tenths of grams (i.e. spring scale or digital balance) and a metric ruler or caliper.

Due to the nature of raw metals, some oxidation or corrosion due to humidity and storage may occur. Simply scuff any oxidation off to make the item look brand new again. These density metals are designed to be used in an educational setting and are not fabricated using ultra high precision machining. Expect tolerances in the +/- 5% range of any stated dimensions (although they are generally much tighter).
