The Chemical Element System/Periodic Table
Alexander Arrangement of Elements

                              with Theo Gray's Element Photos
           ...a classroom size model of the Alexander Arrangement of Elements permits classroom introduction to the periodic table to begin with the REAL element relationships, continuous and contiguous, in an exciting & motivating 3D model.
Learning is Better:   Starting with the Chemical Element System's accuracy, students learn to appreciate the previously perceived periodic table faults to be the very features that give it the credit it deserves.
K.I.S.S.:   The presentation is de-cluttered, and focuses on what simple substances of elements actually exist NOW.
New Motivates:   New, unique, and attractive objects raise the level of interest of everyone everywhere, and the Alexander Arrangement does this in the classroom.
Understanding:   3D models always promote motivation and clarity. Consider how many other models are used in teaching chemistry, biology, and physics.
