Description
What It Is:
A hands-on science worksheet that explores the process of burning, including oxygen use, soot formation, and why candles go out in closed jars. Why Use It:
This activity introduces students to combustion as an irreversible change, while encouraging observation, critical thinking, and scientific explanation. How to Use It:
• Read the background knowledge about burning
• Complete the activity by observing the diagram and answering the questions
• Try the investigation by timing how long a candle burns under a jar (with adult supervision)
Grade Suitability:
Best suited for Grades 4–6 science lessons.
• Grade 4: Introduction to reversible and irreversible changes
• Grade 5–6: Deeper understanding of combustion, gases, and scientific inquiry
Target Users:
Teachers, parents, and students exploring physical science concepts through experiments.
