In this lesson, students will look at examples of reversible physical changes and irreversible chemical changes involving reactants and products. They will categorise different changes accordingly and will learn what indicators to look for to determine whether something is an irreversible change.
Using the experiment proforma sheet, they will carry out four different irreversible change experiments and will discuss their observations before being given scientific explanations for each. Finally, they will carry out a quiz on what they have learnt.
