This ready-to-use cover lesson, based on my separating mixtures 1 (filtration and crystallisation) lesson, allows GCSE students to work independently and develop their understanding of what a mixture is and how they can be separated using filtration and crystallisation through clear explanations and engaging activities. Ideal for unexpected staff absences. 
 
This is the 3rd in a series of lessons and covers the content from the AQA GCSE 4.1.1(.2) A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes topic and OUP Kerboodle GCSE Chemistry Scheme C1.3, Separating mixtures lesson.
