S1 learners were treated to a lesson on fireworks and sparklers from a S3 Chemistry pupil.

S1 recently completed their topic on Elements, Compounds & Mixtures and were broadening their knowledge on the topic with a demonstration relating to a real-word context.

They were guided through the different flame colours provided by different salts containing metal ions, which creates the colourful display from fireworks. Learners were shown a sparkling finale to demonstrate how sparklers work.

Each pupil was given a task to identify the unknown salt by testing to find the flame colour when burned. Working together they successfully identified the 3 salts as sodium chloride which burned with a yellow flame, potassium chloride which burned with a lilac flame, and lithium chloride which burned with a red flame.

Well done Tasnim for delivering this engaging session to S1! She showed great leadership skills in guiding and motivating younger learners in science.
