Neutralisation and pH - Complete lesson (GCSE 1-9)

A full, differentiated lesson based on the new AQA SOW (C5.7). A starter where students categorise items as acidic, alkaline or neutral is used to determine preconceived knowledge. Following this the pH range, acids, bases, and alkalis are discussed making use of examples. Students are prompted to take notes at key points using red font and a pen symbol. The release of H+ and OH- ions is also discussed ahead of methods in determining the pH of solutions. Knowledge is then applied to a differentiated question grid followed by peer/self-marking. A practical exercise (tailored to (C5.7) is then conducted where students prepare a pH curve by systematically adding acid to an alkaline solution using a burette, and monitoring the pH using a probe. Note, pipettes and universal indicator can be used as simple alternatives respectively. Stretch questions are included for the more able. The plenary is based on students reflecting upon their progress against the learning objectives. All answers are incorporated into the slides facilitating self/peer marking and timers are included to promote pace.
