Solids, Liquids and Gases | Explanation Writing Pack | Year 3/4

This fully resourced two-week explanation writing unit explores the science of Solids, Liquids and Gases. Pupils will learn how matter is classified based on its properties, how particles behave in each state, and how materials can change state—all while developing their ability to write clear, structured explanation texts.

Designed using Rosenshine’s Principles of Instruction, this unit builds confidence in explanation writing by explicitly teaching structure, sentence-level grammar, and scientific vocabulary. It is ideal for cross-curricular writing in science or as a standalone non-fiction writing unit.

This pack includes:

• 10 detailed writing lessons with clear learning objectives and modelling
• A two-page WAGOLL (model text) with teacher annotations
• Over 110 editable teaching slides
• 17 pupil worksheets linked to each stage of the writing process
• Sentence stems, success criteria, and scaffolded planning tools
• Grammar focus: fronted adverbials, conjunctions, expanded noun phrases
• Audio version of the WAGOLL for accessible learning
• Dyslexia-friendly fonts and layout
• Quick quizzes, retrieval practice, and built-in assessments

Perfect for full class instruction, small group intervention, or independent writing tasks. This unit not only supports explanation writing outcomes but also reinforces key science knowledge about the three states of matter and how they behave.
