Density Identification Set
Description
This set contains 16 different material samples. Students are challenged to identify the materials by measuring density. Some materials are easily distinguishable while others have nearly identical densities. This leads to discussions of precision, accuracy, and measurement uncertainty.
The set can be used to test students’ abilities to properly find the dimensions, volume, and mass of a solid. These samples can also serve as examples of different materials used in industry. Some are familiar, while others are not commonly seen or recognized. A short description of each substance and its role in industry is provided in the manual.
Included is a lab exercise that guides students through two methods for determining density.
