C12-Chemical analysis- Water purification required practical-lesson created in accordance to the NEW AQA Specification (9-1). Designed for a low ability year 11 class, although content can be adjusted to suit any ability. Includes: slide animations and practice questions with answers on slides as well as a interactive review task. Top tips*I recommend each group is assigned one type of water for dissolved salts part of experiment, collate the results as a class in the end-it'll take forever otherwise. Also, demo the distillation process for a low ability class.
