This materials kit consists 14 materials in the form of rectangular blocks, intended to familiarise students with the appearance, ‘feel’, texture, harness and density of a range of common substances. This set can be used for a range of experiments, from floating and sinking experiments to density of materials and different masses of same sized objects. A great classroom resource for all ages!This set 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.
Contents in size 50 x 40 x 30mm: Wood, paraffin wax, aluminium, iron, foamed polystyrene. In size 20 x 20 x 100mm: Perspex, glass, slate, aluminium, softwood, marble. Blocks in other sizes: Lead (50 x 50 x 20mm), Brass (20 x 20 x 50mm) and Iron (40 x 40 x 20mm).
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).
