Forever Alexander Arrangement of Elements
3D Periodic Table Model
Randomized to Organized, by Allison Despain and Roy Alexander
In this Periodic table introductory activity, students will develop an understanding of the fundamental principles surrounding the correct arrangement of elements for research and study, an appreciation of the task facing the early developers, and the crucial importance of knowing the periodic table for the study and practice of chemistry.
Students will explore element property relationships among elements known to the early developers that led scientists to imagine and build charts that have resulted in an amazingly effective tool for both learning and working with elements/chemistry and the understanding of matter.
Employing pre-periodic table era element teaching aids provided, students will interactively discover element periodicity for themselves, arriving at a logical element arrangement format in three dimensions that converts readily to 2D, providing credibility and clarity to the 2D periodic table they will be using for lab work, study, and testing.
Then teacher will introduce a professional element arrangement 3D model, the Alexander Arrangement of Elements. Students will then compare and contrast teaching and learning competencies among the Alexander Arrangement of Elements, their own models, and the familiar flat periodic table.
Teacher will help reinforce and improve students' understanding of property relationships later used to learn trends, while scaffolding to students' primary use of the standard periodic table flat chart - backed up by the logic and clarity of their own 3D model and the classroom Alexander Arrangement model.
