A differentiated hazard symbols sorting task covering GHS chemical hazard pictograms for KS3, GCSE, and A-level Chemistry, designed to support chemical safety, laboratory hazards, and risk awareness. This resource includes three fully differentiated card sets (KS3, GCSE, and A-level), each containing hazard symbols, names, and clear definitions matched to curriculum expectations. Students group and match symbols to definitions, supporting discussion, recall, and scientific vocabulary development. In addition, XL A4/letter-size PDF hazard cards are included for the KS3 and GCSE sets, designed specifically for whole-class sorting activities, teacher-led demonstrations or classroom and laboratory displays. The XL cards can be printed one per page on A4 or letter-size paper and laminated for durability, then used with blutack or magnets on a whiteboard, around the room for active sorting, or displayed permanently to reinforce hazard recognition and safety awareness. The task works well as a starter, main activity, revision task, or intervention, with an extension encouraging students to categorise hazards into physical hazards and health hazards. Hazards covered include: Explosive Flammable Oxidising Corrosive Gas under pressure Acute toxicity Health hazard / irritant Serious health hazard Hazardous to the environment Hazardous to the ozone layer (A-level) Perfect for Chemistry lessons, lab safety, exam revision, or practical work preparation.

A KS3 card sort activity designed for Year 7 as part of the sexual reproduction topic, focusing on the stages of sex cell fertilisation and baby development. Suitable for use across all KS3. Students work in pairs to match images to descriptions and stage names, then arrange the stages in the correct chronological order, supporting understanding of biological processes, sequencing, and scientific vocabulary. A full set of cards fits onto one A4 page, making preparation quick and efficient for whole-class use. For best results, the sheets can be laminated for durability and reuse, with full A4 sheets laminated before cutting using a guillotine to allow for fast, repeatable prep. The activity is ideal as a main lesson task, consolidation activity, or revision, and includes a PowerPoint with answers for easy checking, modelling, or self-assessment.
