Develop children's understanding of what heating does to states of matter with this Year 4 What Happens When We Heat Materials? Investigation Lesson.

In this Year 4 lesson, pupils will engage in a practical investigation to observe how water changes state when heated and the key concepts involved, recording findings in a table and graph to draw scientific conclusions from their fair test.
