CB3 Genetics GCSE Lesson Booklets

EAL Genetics Biology Booklets

Features

• • Key vocabulary sections with simple definitions and pronunciation guides

• • Gap-fill activities with word banks provided
• • Differentiated tasks labelled by difficulty (Foundation, Developing, Extension)
• • Varied question types: multiple choice, true/false, sorting, short answer, and exam-style
• • Diagrams and labelling tasks (cell structure, Punnett squares, pedigree diagrams)
• • Knowledge retrieval starters to revisit prior learning
• • Exam-style questions with mark allocations matching GCSE paper format
• • Sentence starters for extended writing (explaining, comparing, evaluating)
• • Self-assessment checklists with space for student reflection and teacher feedback
• • Aligned to GCSE specification references (Edexcel CB3e, CB3f, B3.19–B3.23)

Topics Covered

• Booklet 1: DNA (Deoxyribonucleic Acid) Covers what DNA stands for, where DNA is found in a cell, the structure of DNA as a double helix, the four bases and complementary base pairing (A-T, C-G), nucleotides and polymers, hydrogen bonds holding strands together, and a practical extension on DNA extraction.
• Booklet 2: Genetic Inheritance & Sex Determination (GCSE Biology – Topic B6, Lesson 3) Covers genes and alleles, dominant vs recessive alleles, homozygous and heterozygous genotypes, genotype vs phenotype, how to draw and interpret Punnett squares, predicting genetic outcomes and probability, and sex determination using XX/XY chromosomes.
• Booklet 3: Inheritance, Mutations & Pedigree Diagrams Covers a retrieval review of alleles and inheritance, variation (inherited vs environmental), continuous and discontinuous variation, mutations (what they are, their effects, mutagens), and reading and interpreting pedigree diagrams to track genetic conditions through families.
• Booklet 4: Variation, Mutations & The Human Genome Project (GCSE Biology – CB3e & CB3f, Edexcel Spec Refs B3.19–B3.23) – Text Version Covers genetic and environmental variation, acquired characteristics, discontinuous and continuous variation (including normal distribution, mean, median, mode, range), gene mutations and their link to phenotype change, UV radiation and skin cancer, and the Human Genome Project — its achievements, personalised medicine, and drug response variation.
• Booklet 5: Variation, Mutations & The Human Genome Project – Image-Enhanced Version Same topic coverage as Booklet 4, with embedded images and diagrams added throughout.

Why These Are a Great Resource
These booklets remove language as a barrier to science learning. EAL students often understand the science but struggle with the English required to access it — word banks, pronunciation guides, and sentence starters deal with that directly.
