Additional Details

The 5-piece set offers students a diverse range of densities for comprehensive study. Perfect for physics classrooms, this set facilitates investigations into density, specific heat, and specific gravity.

The concept of density is important in many real world situations.

*Engineers and Architects need to understand density to select the best materials for the job. This knowledge helps them make the most suitable choices based on factors like strength-to-weight ratio, buoyancy, and thermal properties.

*Testing density is a key way of discovering flaws and inconsistencies in manufactured products.

*Environmental scientists need to understand the density of pollutants to determine how they will move through the environment and where they are likely to collect.

Oxidation may occur with the metal cylinders and can be removed using a coarse cloth.
