ABSTRACT:
The invention includes a three dimensional periodic table of the chemical elements and a method of learning about the periodic nature of the elements. Included are several cardboard or paper sheets, each having a plurality of blocks that display information about particular elements. The blocks are arranged in groupings of elements with similar properties, such as the transition Earth metals. Students follow a set of instructions provided with the sheets to cut out the groups, fold along particular lines, and affix tabs together to assemble several three dimensional forms. The students then place the forms on a planar map that indicates where to place each form and indicates how to follow the periods of elements between the forms.
