A range of differentiated worksheets covering different aspects of particles in KS3 and KS4 Chemistry. Focus is on learning to recognise and describe the different types of particles that crop up throughout school chemistry including atoms, molecules, ions and subatomic particles, and how they make up elements and compounds. Sheets can be used in context of learning units, or brought in when prior learning is sketchy and in need of consolidation or clarification. Useful as plenaries, for revision, or as starters to get a quick assessment of prior learning to inform planning. Answers sheets or power points are also included for quick in class marking.
