4.1 The Periodic Table

Unit Summary

This unit is aligned with the AQA Trilogy Chemistry specification and is designed to be sequenced flexibly. However, it is structured with the assumption that each year builds upon the knowledge and skills developed in previous units.

The unit examines the organisation of the Periodic Table, the properties of elements in different groups, and the trends in reactivity of key element families, including the alkali metals, halogens, noble gases, and transition metals with their characteristic properties. Pupils will develop an understanding of how the arrangement of elements relates to their atomic structure and chemical behaviour. The unit incorporates hierarchical elements of working scientifically, allowing pupils to progressively develop their investigative skills, including making observations, recording data, and evaluating methods. While prior learning from earlier key stages is considered, the unit also provides prompts and scaffolds to support understanding, ensuring accessibility for all learners.

To support ongoing assessment and deep learning, a variety of Assessment for Learning (AFL) strategies are embedded within each lesson. These include retrieval practice, formative questioning, and structured activities designed to reinforce key concepts, address misconceptions, and develop long-term retention of knowledge.

Developing Experts is committed to supporting schools in delivering the National Curriculum effectively. Our curriculum design is primarily guided by National Curriculum content, but we also extend beyond these requirements to provide greater challenge and aspiration. This is achieved by connecting classroom concepts to real-world applications, particularly in the world of work
