History of the Atom – Free Sample Lesson for Edexcel GCSE Chemistry

A fully resourced GCSE Chemistry lesson on the development of the atomic model, designed for the Pearson Edexcel GCSE Chemistry (9–1) specification.

This classroom-ready lesson explores how the atomic model developed as new experimental evidence became available. Students follow the progression from Dalton and Thomson through Rutherford, Bohr and Chadwick, including the alpha-scattering experiment and the evidence that led to the nuclear model.

Includes:

• Editable lesson PowerPoint with answers
• Clear learning objectives and AfL/checkpoints
• Support, Core and Stretch activities
• Retrieval, application and GCSE-style questions
• Print-ready classroom resources

This is the first lesson from the complete five-lesson AchieveWithZora: Schools Edition Atoms unit, which continues into atomic structure, electronic structures, isotopes, relative atomic mass and ions, with Edexcel specification mapping, revision materials, assessment, mark schemes and targeted feedback.
