Lesson plan
Arrange the class into groups of three and hand out three sticky notes to each group.
Challenge the children to write the names of the three states of matter (solid, liquid and gas) with one name on each sticky note. Hand out the Knowledge organiser to pupils requiring support (see Adaptive teaching).
Ask each group member to choose one of the sticky notes and explain they will represent their chosen state of matter in a class model. They should stick their sticky note to their chest to show their state. Arrange the class so the gases, liquids and solids are grouped in different areas of the classroom.
Recap the changes of state by:
Asking the pupils who are gases to point to the state they will turn into if they are cooled down (liquid).
Asking the pupils who are liquids to point to the state they will turn into if they are warmed up (gases).
Asking the pupils who are solids to point to the state they will turn into if they are warmed up (liquids).
Asking the pupils who are liquids to point to the state they will turn into if they are cooled down (solids).
