Adaptive teaching
Pupils needing extra support
Could focus on recording how easily each material ignited on the Activity: Observing burning; could use the Knowledge organiser to help them analyse the statements in the Recap and recall and answer the questions in the Attention grabber; should read the information under the video at the link: Irreversible changes instead of the Wrapping up activity.
Pupils working at greater depth
Should write their conclusion to the rusting experiment independently; should time how long each material burnt for and record this in the last column of the table on the Activity: Observing burning; could choose an extension activity relating to reversible and irreversible changes from the Resource: Stretch and challenge: Properties and changes.

Knowledge outcomes
- I can define the term irreversible change as when a material undergoes a change that cannot be easily reversed and which produces a new material or materials.
- I can identify rusting as an irreversible change and describe the conditions required (water and air/oxygen).
- I can identify burning as an irreversible change and describe the differences between how some different materials burn.
