During Tuesday’s science class, the year 7X students, led by Ms Cheryl-Ann Cuschieri, were studying the fire triangle. They carried out a simple investigation making use of a candle, coloured water and a beaker. They realised that oxygen is needed for burning to take place and once oxygen is depleted, the candle extinguishes. This then led to the level of water in the beaker increasing to equalize the difference in pressure present.
