We present results from computational experiments of one-dimensional inhomogeneous granularcolumn. With characteristic properties lying between those of liquids and solids, this class of materialconsists 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 columnof spherical beads driven by a sinusoidally vibrating plate. Results for 10 bead experiments showthe fluidization and condensation phenomena, both dependent on the amplitude and frequency ofthe driving plate. Some scaling properties arising from the dynamics of the beads are also shown
