KS3 Biology — Stem Cells in Animals — Extension Pack

🧫 Stretch high achievers further with four ready-to-use enrichment activities on stem cells — no preparation required. Stem cells are unspecialised cells that can divide and develop into different cell types through a process called differentiation, and these tasks push students to apply that thinking, for KS3 students aged 11–14.

📦 What's included:

Vocabulary Matching (15 terms) — covering zygote, embryo, mitosis, embryonic and adult stem cells, differentiation, self-renewal, bone marrow, red blood cells, white blood cells, platelets, induced stem cells, fertilisation, and genes

Challenge Quiz (25 marks) — a data analysis question on red blood cell production rates with a calculation, a radiation scenario question, a gene-level explanation of how 200 cell types arise from identical DNA, an evaluation of induced vs embryonic stem cells, and an analogy evaluation task

Bone Marrow Transplant Case Study (20 marks) — leukemia treatment covering self-renewal and differentiation, donor compatibility, transplant risks, and the potential of induced stem cells

Teach It Back task — students write a stem cell mini-guide for a Year 6 audience, assessed with a detailed rubric

Full answer keys and marking guidance included for all four activities.
