It is a well documented fact that three dimensional models of complex concepts and principles usually enhance teaching and learning at all developmental levels.
The Three Dimensional table of the Elements comes with a User’s Guide directed at the early childhood and elementary levels. This is not intended to be a curriculum guide but it can serve as a resource for the names of the elements, their symbols, atomic numbers and atomic weights.
The Elliptical Periodic Chart of the Elements is the precursor to the three-dimensional model. Whereas in the flat elliptical chart the Transition Elements fit most naturally, in the three dimensional model, they maintain their sequence but snake inwardly and form double rows in order to reduce the size of the circle that must accommodate the 32 elements in Periods 6 and 7.
