Density Set, Brass Set of 12

**Delivery in 3 - 5 weeks**

Set of 12 brass cylindrical bars. Each cylinder is the same diameter, 0.5" (12.5mm) but each has a different length. Set includes a wooden storage block.
Excellent for physics classrooms. Density metals have 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).
