Periodic Table Lesson Pack – History, Patterns, Groups & Trends - KS3

A clear, ready-to-teach lesson pack designed to introduce KS3 students to the development and structure of the periodic table. The lessons help students understand how scientists organised elements and how patterns in the table allow us to predict properties.

This resource includes six fully editable PowerPoint lessons that guide students from the early history of elements through to the modern periodic table and how scientists use it today. The sequence builds understanding step-by-step, combining historical context with key chemistry ideas.

The lessons move from early scientific ideas → development of classification systems → Mendeleev’s breakthrough → modern periodic table structure → real-world applications.
