Cassagrande apparatus is used to determine the liquid limit of soils. Liquid Limit is defined as the water content at which the soil changes from liquid state to plastic state.

Hydrometer method is used to determine the particle size distribution of fine-grained soils passing 75 $\mu$ sieve. The hydrometer measures the specific gravity of the soil suspension at the Centre of its bulb. The specific gravity depends upon the mass of solids present, which in turn depends upon the particle size.

Plate Load Test is a field test for determining the ultimate bearing capacity of soil and the likely settlement under a given load. The Plate Load Test basically consists of loading a steel plate placed at the foundation level and recording the settlements corresponding to each to increment.
An oedometer test is a test that measures a soil's consolidation properties. Oedometer tests are performed by applying different loads to a soil sample and measuring the deformation response. The results from these tests are used to predict how a soil in the field will deform in response to a change in effective stress.
