Year 4 Science | States of Matter | Lesson 2: What Is Water Vapour?
What is water vapour, and how do we help pupils understand it clearly? In this lesson, part of our Scintillating Science programme, children explore how water changes state through observation, discussion, and simple practical investigation. The lesson supports key concepts from the Ofsted science subject report and builds on prior knowledge from Lesson 1.
Science Scheme | Year 4 | Block 1: States of Matter | Lesson 2: What Is Water Vapour? focuses on the processes of evaporation and condensation. Pupils will observe how water transforms from liquid to gas, identify changes in state, and begin to use scientific vocabulary to explain what they see.
This lesson is part of our full States of Matter unit for Year 4, which covers solids, liquids, gases, and changes of state through enquiry-led learning.
What you’ll find in this lesson
- 🧪 Clear, interactive slides to introduce and model scientific ideas
- 🧪 A fully planned lesson with vocabulary, misconceptions, and teacher guidance
- 🧪 Differentiated worksheets and hands-on activities to suit a range of learners
- 🧪 Optional continuous provision ideas for follow-up and exploration
Through guided questions and investigation, pupils develop their working scientifically skills, observe real-life examples of evaporation, and start to link changes of state to wider scientific processes like the water cycle.
This lesson also supports discussion, reasoning, and confident use of scientific language—making abstract concepts accessible to all pupils.
