  Extradimensional models are achieving their highest popularity nowadays,
among other reasons, because they can plausible explain some standard cosmology
issues, such as the cosmological constant and hierarchy problems. In
extradimensional models, we can infer that the four-dimensional matter rises as
a geometric manifestation of the extra coordinate. In this way, although we
still cannot see the extra dimension, we can relate it to physical quantities
that are able to exert such a mechanism of matter induction in the observable
universe. In this work we propose that scalar fields are those physical
quantities. The models here presented are purely geometrical in the sense that
no matter lagrangian is assumed and even the scalar fields are contained in the
extradimensional metric. The results are capable of describing different
observable cosmic features and yield an alternative to ultimately understand
the extra dimension and the mechanism in which it is responsible for the
creation of matter in the observable universe.
