Secondary 2 – Chemistry: Exploring Energy Changes on Exothermic and Endothermic Reaction
Secondary 2 students conducted an experiment to explore exothermic and endothermic reactions. Using common household items such as baking soda, vinegar, water and sodium hydroxide, the students demonstrated their understanding of energy changes in chemical processes. The activity took place in the school laboratory under the supervision of their teacher. The students worked in small
