Changing States of Matter | Explanation Writing Pack | Year 3/4

This fully resourced two-week explanation writing unit explores the fascinating science topic Changing States of Matter. Pupils will learn how materials can change from solids to liquids to gases—and back again—through real-world examples and accessible science explanations, all while building structured and confident writing.

The unit follows Rosenshine’s Principles of Instruction to provide carefully sequenced lessons that model key writing features and reinforce grammar skills. It supports pupils in organising their ideas clearly, using scientific vocabulary accurately, and developing well-structured explanation texts linked to the science curriculum.

This pack includes:

• 10 full writing lessons with clear objectives and direct modelling
• A two-page WAGOLL (model text) with teacher annotations
• Over 110 editable slides for guided whole-class teaching
• 17 pupil worksheets to support structured writing tasks
• Sentence stems, success criteria, and scaffolded support
• Grammar focus: conjunctions, fronted adverbials, expanded noun phrases
• Audio version of the WAGOLL to support accessibility
• Dyslexia-friendly fonts and clear layout
• Retrieval quizzes, recap tasks, and assessment opportunities

Ideal for writing across the curriculum (Science: States of Matter), this unit is perfect for full class instruction, small group support, or independent explanation writing assessment.
