About This IB MYP Science Workbook
The IB MYP Science Criterion B workbook is designed for Year 9 and MYP 3 students who want to excel in planning scientific investigations. It transitions students from understanding basic energy concepts to rigorously designing testable experiments.
The workbook breaks down Criterion B into its four key strands: explaining scientific problems, formulating hypotheses with scientific reasoning, planning variable manipulation and data collection, and designing logical, safe experimental methods.
With worked models, guided practice, and differentiated exam sets, students learn not just what to do, but how to scientifically justify every choice for Level 7โ8 success.
What's Included in This Workbook?
๐ 4 Criterion B Strands
Structured guidance covering problems, hypotheses, variables, data collection, and experimental design.
๐ฏ Level 7โ8 Justifications
Learn how to scientifically justify ranges, intervals, repeats, and control variables for top grades.
Two complete 30-mark exam sets including calorimetry and a 12-mark open-design wind turbine task.

Understanding Criterion B
Detailed breakdown of strands i, ii, iii, and iv, achievement band descriptors, and command terms.
Research Questions
Transforming vague ideas into focused, testable questions with clear independent and dependent variables.
Variables & Controls
Mastering IV, DV, and how to control variables while explaining why each control matters.
Scientific Hypotheses
Writing IfโThenโBecause hypotheses supported by energy equations (GPE, KE, and friction).
Data Planning
Selecting appropriate ranges, evenly spaced values, repeats for anomalies, and instrument resolution.
Method Design
Writing reproducible, numbered instructions using imperative verbs and structured equipment lists.
Risk Assessment
Integrating safety into design using the Hazard, Risk, and Precaution framework.
Ramp Model Investigation
Complete worked Level 7โ8 model examining how release height affects the speed of a toy car.
Bouncing Ball & Launcher
Investigating gravitational energy retention and elastic potential energy conversion.
Pulleys & Levers
Designing experiments to measure mechanical efficiency and effort forces.
Fuel Calorimetry
Comparing energy released per gram across alcohol fuels using spirit burners and copper cans.
Wind Turbine Design
Open-ended expert task testing how blade count affects electrical power output.
Workbook Features & Support
Designed to build complete independence in scientific planning.
Model Investigations
Clear step-by-step examples so students see exactly what a top-tier design looks like.
Common Mistakes
Guidance on avoiding vague steps, unreasoned hypotheses, and insufficient data ranges.
Guided Practice
Targeted exercises building skills before tackling full exam papers.
Revision Checklist
Comprehensive self-assessment list for students before their Criterion B assessment.
Why Choose This Criterion B Workbook?
Criterion B can be challenging because investigation design requires scientific justification rather than rote memorisation. This workbook teaches students how to defend their experimental choices logically.
By pairing foundational energy theory with rigorous inquiry practice, students gain the confidence to plan, evaluate, and execute scientific investigations independently.
Who Is This Workbook For?
๐ Year 9 Students
MYP 3 students preparing for IB Science Criterion B assessments and investigations.
๐จ๐ฉ๐ง Parents
Parents looking for structured resources to help their children master scientific planning.
๐ฉ๐ซ Teachers & Tutors
Educators needing ready-to-use assessment tasks, mark schemes, and inquiry worksheets.
