this method is used to determine the field density of soil and bulk density of soil wrt to sand.
this method is not suitable for organic , saturated. highly plastic soil that will deform during the excavation of soil.
The in-situ density of the soil is required to control the results of field compaction in earth embankments, Road fill and structural back filling. So, measuring the soil density is essential before building any construction. Three methods are used to determine the density (unit weight) of a soil in the sight; the sand replacement method, the balloon method, and the nuclear method.
gravity method
it replaces the wax used in casting.
Rub a finger over the mineral
scientific method
sand replacement method is used for determining the dry density of soil
Core cutter method is simple but results approximate and used on soft soils

Experiments are a method for finding solutions to problems.
