A comprehensive IB Biology Internal Assessment / Scientific Investigation support bundle designed to guide students through the entire IA process while giving teachers practical, ready-to-use tools for teaching, feedback, intervention and redrafting.

This bundle brings together five substantial editable resources covering everything from understanding the assessment criteria and developing a research question to processing data, interpreting statistics, writing strong analysis and responding to teacher feedback.

The current Biology Scientific Investigation is assessed using four equally weighted criteria — Research Design, Data Analysis, Conclusion and Evaluation — each worth 6 marks, for a total of 24.

Included in the bundle

1. IB Biology IA Student Guide
   A clear, student-friendly guide explaining the requirements of the Scientific Investigation and what stronger performance looks like across all four criteria. Includes practical advice, common pitfalls, top-band guidance and a final submission checklist.

2. IB Biology IA Teacher Feedback & Marking Checklist
   A practical teacher tool designed to make draft marking quicker and more consistent. Includes tick-box strengths, targeted improvement points, provisional marks, student next steps and clear redrafting priorities.

3. IB Biology IA Planning & Writing Workbook
   A structured workbook taking students from their first idea to the completed investigation. Supports research-question development, variables, methodology, pilot work, repeats, safety, data collection, processing, analysis, conclusion, evaluation and final redrafting.

4. IB Biology IA Data Presentation, Statistics, Uncertainty & Measurement Toolkit
   An in-depth toolkit covering:

raw and processed data
graph selection and presentation
significant figures
accuracy and precision
random and systematic error
measurement uncertainty
biological variation
mean, median and range
SD, SE and confidence intervals
error bars
uncertainty propagation
correlation and statistical testing
worked Biology examples
decision charts and checklists

This resource is particularly valuable because top-band Data Analysis requires clear and precise processing together with appropriate consideration of uncertainties.

1. IB Biology IA Analysis Writing Toolkit
   Designed to help students move beyond description and write stronger scientific analysis using the structure:

Pattern - Evidence - Uncertainty - Statistics - Biological Explanation - Anomaly - Link

Includes model paragraphs, vocabulary banks, sentence starters, graph-interpretation exercises, fictional practice datasets, self-assessment and teacher feedback support.

Flexible for different teaching styles

All five resources are designed to be modular.

Teachers can use the complete bundle as an IA programme or select individual pages for:

• whole-class teaching
• IA workshops
• individual conferences
• draft feedback
• targeted intervention
• peer assessment
• independent study
• redrafting

The resources also work together particularly well. For example, a teacher can use the Feedback & Marking Checklist to identify a weakness, then direct the student to the relevant page in the Statistics, Analysis Writing or Planning Workbook for specific support.

The Biology IA allows a range of investigation approaches, including laboratory work, fieldwork, database investigations, spreadsheet/modelling and simulations, so the resources are designed to support more than one type of scientific investigation.

Ideal for: IB Biology SL & HL
Format: 5 editable Microsoft Word resources
Use for: IA planning, data analysis, statistics, uncertainty, drafting, redrafting, teacher feedback and final submission preparation

A complete Biology IA support package for teachers who want structured resources, clearer student independence and more focused feedback from first idea to final submission.
