Chapter Name: Materials and Things
Activity Name: Light a candle in Materials and Things
The experiment explores lighting a candle without directly touching the wick with a burning matchstick. It involves observing the behavior of the candle’s smoke and its ability to ignite from a distance.
Step by Step Procedure:
- Place the candle in a safe location and light it using a matchstick by touching the wick.
- Allow the candle to burn for approximately two minutes.
- Blow out the flame of the candle using a burning matchstick.
- Observe the column of white smoke rising from the extinguished wick.
- Without touching the wick, bring the burning matchstick close to the smoke.
- Observe and record the results. Did the candle catch fire from a distance?
- When the flame of the candle is extinguished, a column of white smoke rises from the wick.
- When the burning matchstick is brought close to the smoke without touching the wick, the candle may catch fire from a distance.
- Conduct the experiment in a well-ventilated area to ensure safety.
- Keep flammable materials away from the experiment setup.
- Handle the burning matchstick with caution to avoid accidental burns.
Lesson Learnt from Experiment:
The experiment demonstrates that a candle can be lit from a distance by utilizing the column of white smoke that rises from the extinguished wick.
The white smoke represents the gaseous state of the candle wax, which is flammable and can ignite when exposed to a flame, even without direct contact. This experiment highlights the concept of flammable gases and their ability to ignite under specific conditions.
