- Abstract: Teaching the periodic table is a central part of chemistry. This might involve memorizing the symbols of the elements, learning about the properties of the families, or understanding its general organization. This year, The International Year of the Periodic Table, marks its 150th anniversary, and represents a good opportunity to highlight its history. The underlying patterns described by periodic law, such that the table is organized horizontally by the number of protons and vertically by similar chemical properties in addition to the repeating patterns associated with those electrons found in the outermost shell of an atom correlate with the "Next Generation Science Standards (NGSS)" Disciplinary Core Idea (DCI) Structure and Properties of Matter (PS1.A) (NGSS Lead States 2013). Furthermore, observing patterns and the relationships underlying them is one of the key crosscutting concepts found in the "NGSS". The following lesson in this article requires about two traditional class periods or one block period and follows the 5E Instructional Model designed by the Biological Sciences Curriculum Study (Bybee 2014) with the added Elicit stage proposed by Eisenkraft (2003). Students first emulate Dmitri Mendeleev's own experience with organizing the elements through a puzzle activity, using patterns to make predictions. Then after reading a non-fiction text about his contributions (Bryson 2008), students gain a foundational understanding of the patterns within the periodic table before spending time exploring the properties of the families.
