Mini Lesson

A science journal is a personal record of your scientific investigations. Scientists use journals to write down questions, predictions, methods, results, and conclusions. Keeping a well-organized journal helps you track your learning and communicate your findings to others.

Science Report Structure: Q-P-M-R-C

  1. Question (Q) — What do I want to find out? State your investigation question clearly.
  2. Prediction (P) — What do I think will happen? Give a reason for your prediction.
  3. Method (M) — How will I test my idea? List materials and steps in order.
  4. Results (R) — What did I observe or measure? Use tables, drawings, and data.
  5. Conclusion (C) — What did I learn? Compare results to prediction and explain.

Setting Up Your Journal

  • Cover page — title, your name, grade, and year.
  • Table of contents — list each investigation with its page number.
  • Date each entry — always write the date at the top of each page.
  • Use clear headings — label each section: Question, Prediction, Method, Results, Conclusion.
