KS3 Biology — Heredity — Extension Pack

🧬 Stretch high achievers further with four ready-to-use enrichment activities on heredity — no preparation required. Heredity is the process by which features are passed from parents to their offspring through reproduction, and these tasks push students to apply that thinking, for KS3 students aged 11–14.

📦 What's included:

Vocabulary Matching (12 terms) — covering reproduction, offspring, heredity, inherit, species, variation, siblings, genetic material, nucleus, inherited features, identical twins and life cycle

Challenge Quiz (25 marks) — true/false questions, short answer tasks, and a data interpretation question using a table of five kittens from a black-and-white cat and a ginger cat, calculating mean tail length and explaining variation

Labradoodle Case Study (20 marks) — the history and breeding of the Labradoodle crossbreed, with six questions on heredity, inherited features, and variation

Teach It Back task — students write a guide explaining heredity to a Year 5 student, assessed with a five-criteria rubric covering accuracy, clarity, key word use, example quality, and structure

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