POLOKWANE – Last Tuesday, Gr 10 learners at PEPPS got hands-on with stoichiometry, turning their chemistry lesson into a fun and interactive experiment.

Stoichiometry, a key branch of chemistry, focuses on the quantitative relationships between reactants and products in chemical reactions. It involves calculating mass, moles and volume based on balanced chemical equations.

Under the guidance of teacher Timmy Mahlane, learners used vinegar and baking soda to explore how varying amounts of base influence the production of carbon dioxide gas.

“Watching the balloons inflate and observing the reactions wasn’t just fun, it was a powerful lesson in mole ratios, limiting reagents, and real-world chemistry,” said Mahlane.

“It was great to see how focused the learners were and how they answered questions based on their observations.”
