We present results from computational experiments of one-dimensional inhomogeneous granular
column. With characteristic properties lying between those of liquids and solids, this class of material
consists of assemblies of solid particles which interact via mechanical forces (contact and friction)
and are maintained together by a gravitational field. The system is composed of a vertical column
of spherical beads driven by a sinusoidally vibrating plate. Results for 10 bead experiments show
the fluidization and condensation phenomena, both dependent on the amplitude and frequency of
the driving plate. Some scaling properties arising from the dynamics of the beads are also shown.
