4.3 (a)

• Class practical using the mini Boyle's law apparatus to get a "hands on" feel of the law. The aren't very accurate but do give a nice curve. However, it dosn't give any sort of proportionality.
• Demo Boyle's law set up. Have pupils carry out the experiment with different pupils doing different tasks. This gives good data when repeated.
• Although not in the spec explicitly you can have the other half the group doing the constant volume experiment.
