About this guide
This year marks the 150th anniversary of the periodic table. Use this guide to introduce students to the history and development of the periodic table, to the periodic table as a model and to scientific models more generally. Students will explore patterns in the arrangement of chemical elements on the table and patterns in the reactivity of those elements.
This Guide Includes:
Go beyond Mendeleev’s model
These discussion prompts encourage students to think about the principles and purposes of scientific models in all areas of science and engineering.
Now trending, the Periodic Table
After watching videos about the periodic table, students will identify general patterns in the table.
The Periodic Table: A nuclear view
Students will learn how interactions among the protons and neutrons in the atomic nucleus affect the properties and stability of chemical elements, and how these properties could inform the creation of future elements.
