MYP Grade 10 Biology: 21 Criterion B Assessment Tasks Bundle - 2026

This editable MYP Grade 10 Biology bundle brings together a full set of in-class Criterion B: Inquiring and Designing assessment tasks for the main Grade 10 Biology units. ***The individual unit packs are already 25% off.*** ***Save an additional 10% with this bundle.*** The bundle is designed to help students practise and demonstrate the key skills required for Criterion B, including writing focused research questions, formulating hypotheses, identifying variables, planning data collection, constructing results tables, designing valid methods, and considering reliability, validity, safety, ethics, and limitations. **What is included:** • 21 editable Criterion B student tasks • 21 teacher mark schemes • In-class assessment format • Research question practice • Hypothesis writing practice • Variables tables • Results table construction • Method design questions • Validity and reliability prompts • Safety, ethical, and limitation considerations where relevant • Mark scheme guidance for each Criterion B strand **The bundle covers the following Grade 10 Biology units:** Unit 1: Cell Biology • Osmosis and potato cell mass • Diffusion and concentration gradient • Membrane permeability and temperature Unit 2: Molecular Biology • DNA extraction and temperature • Catalase activity and hydrogen peroxide concentration • Amylase activity and pH Unit 3: Genetics • Mendelian segregation and sample size • Continuous variation and hand span • Discontinuous variation and inherited traits Unit 4: Ecology • Quadrat sampling and vegetation cover • Water quality and macroinvertebrate species richness • Decomposition and temperature Unit 5: Evolution and Classification • Natural selection and prey colour frequency • Antibiotic resistance and zone of inhibition • Selective breeding and seed length Unit 6: Human Physiology • Exercise intensity and heart rate • Practice and reaction time • Amylase concentration and starch breakdown Unit 7: Plant Biology • Light intensity and photosynthesis • Wind speed and transpiration • Temperature and seed germination Each task is fully editable, allowing teachers to adjust the wording, level of support, investigation context, practical details, examples, data tables, or mark scheme expectations to match their own teaching sequence and the specific content delivered in class. The teacher mark schemes provide model answers, accepted alternatives, scientific explanations, validity notes, safety and ethical guidance, graphing guidance, and advice on what stronger responses should include. This supports consistent marking and helps teachers see how students can access each Criterion B strand. This bundle is suitable for MYP Grade 10 Biology, in-class Criterion B assessments, end-of-unit inquiry tasks, assessment preparation, classroom assessment, or revision of investigation design skills across the Biology course.
