Core Skills Analysis
Science
- Identified the three components of the fire triangle (heat, fuel, oxygen) through direct observation of a candle flame.
- Applied the concept of oxygen consumption by noting the flame extinguished when the glass sealed off air.
- Practiced hypothesis testing: Scout predicted a smaller flame, then compared the result to the actual outcome.
- Engaged in cause-and-effect reasoning by explaining why removing oxygen stops combustion.
Mathematics
- Estimated the size of the glass and the candle flame, reinforcing skills in visual measurement and proportion.
- Recorded the time taken for the flame to go out, linking observations to seconds and minutes.
- Used simple data comparison (predicted vs. actual) to develop early statistical thinking.
- Applied basic geometry by discussing the shape of the glass and how it encloses space.
English (Language Arts)
- Formulated a clear prediction sentence, strengthening future‑tense phrasing and scientific vocabulary.
- Participated in a group discussion, practicing turn‑taking, active listening, and explanation skills.
- Used descriptive language to explain why the flame disappeared, enhancing cause‑and‑effect writing.
- Reflected on the experiment in a short oral summary, supporting oral communication competence.
PSHE / Safety
- Recognised safe handling of fire by using a candle under supervision, reinforcing fire safety rules.
- Observed the importance of ventilation when working with open flames, linking to personal health.
- Developed responsibility by cleaning up the experiment area after completion.
- Discussed teamwork and respectful listening during the prediction and explanation phases.
Tips
To deepen understanding, try repeating the experiment with different sized glasses to see how volume of air affects flame duration, then graph the results. Follow up with a hands‑on activity where children build a simple model of the fire triangle using colored paper to visualize each element. Incorporate a short writing task where they journal the steps, predictions, and conclusions, encouraging scientific notation. Finally, connect the concept to everyday life by exploring how extinguishers, car engines, and campfires rely on controlling the fire triangle, perhaps through a field trip to a local fire station.
