Our Year 7 students recently enjoyed an outdoor Chemistry experiment as part of their Chemistry Main Lesson, which explores the nature of fire and its properties. While we have all seen fire at multiple points in our lives, closer examination proves that our understanding of it is actually rather limited.  In their experiment, the students collect matter from the bush and skilfully build a bonfire using skills acquired in outdoor education.  They then observed how the four candles set at the base were sucked into the fire while a pinwheel held above it would spin in the upward current of air.  The wood disappeared and was transformed into heat, smoke and ash through chemical change caused by the fire. The students will then collect smoke and infuse it into water to create "smoke water".  The ashes will also become "ash water".  These will both be tested using homemade red cabbage juice indicator and prove to possess acidic and basic qualities, respectively.
