Everything you need to teach cells at KS3 — four complete lesson packs covering the whole topic, full answer keys throughout, and no preparation required. This bundle covers the seven life processes, unicellular and multicellular organisms, and the structures inside animal and plant cells, for students aged 11-14.

Cells are the basic building blocks of every living thing, and this bundle takes students from what makes something alive right through to how specialised cells are adapted for their job. Each of the four lesson packs contains a main worksheet with 100 marks across three progressive sections — knowledge recall, application and understanding, and extension and analysis — plus an extension pack with four enrichment activities per topic. Every worksheet and extension activity includes a full answer key with detailed marking guidance, so there’s genuinely nothing left to prepare.

This bundle is ideal for covering an entire cells unit without sourcing four separate resources, whether you’re teaching the topic in sequence across several lessons or setting it as a block of homework and revision material. Students progress from foundational concepts — the seven life processes and the difference between unicellular and multicellular organisms — through to detailed cell structure and function, building the knowledge base that underpins the rest of KS3 Biology.

Buying this bundle saves £5 compared to purchasing all four lesson packs separately (4 x £5 = £20 individually, £15 as a bundle).
