MYP Grade 10 Chemistry: 24 Criterion B Tasks Bundle - 2026

This editable MYP Grade 10 Chemistry bundle brings together a full set of in-class Criterion B: Inquiring and Designing assessment tasks for the main Grade 10 Chemistry 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, and limitations. **What is included:** * 24 editable Criterion B student tasks * Full 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 and limitation questions where relevant * Mark scheme guidance for each Criterion B strand **The bundle covers the following Grade 10 Chemistry units:** Unit 1: Atomic Structure and the Periodic Table * Modelling atomic structure across elements * Isotopes and relative atomic mass * Ionisation energy and electron configuration * Atomic radius across Period 3 * Electronegativity and bond classification * Group 1 reactivity with water **Unit 2: Chemical Bonding** * Bonding type and melting point * Molecular polarity and solubility * Metallic bonding and electrical conductivity **Unit 3: Chemical Reactions** * Exothermic and endothermic reactions * Temperature and rate of reaction * Conservation of mass **Unit 4: Acids, Bases and Salts** * pH scale and acid/base definitions * Strong and weak acids * Neutralisation and salt formation **Unit 5: Kinetics and Thermochemistry** * Concentration and rate of reaction * Surface area and rate of reaction * Enthalpy of combustion **Unit 6: Electrochemistry** * Electrolysis of sodium chloride solution * Electroplating and the effect of current * Galvanic cells and the reactivity series **Unit 7: Organic Chemistry** * Alkanes: boiling point and chain length * Alkenes: testing for unsaturation using bromine water * Fermentation: effect of glucose concentration 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 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 Chemistry, in-class Criterion B assessments, end-of-unit inquiry tasks, assessment preparation, classroom assessment, or revision of investigation design skills across the chemistry course.
