Practicals are fundamental in lower secondary science, transforming abstract concepts into tangible understanding. They bridge the gap between theory and reality, fostering crucial skills like observation, analysis, and logical thinking.
The litmus paper test is a perfect introductory practical. This simple yet powerful experiment allows students to directly witness the properties of acids and bases. By dipping the paper into various household solutions like lemon juice or soapy water, they see an immediate colour change. This active participation makes the abstract concept of pH concrete, creating a memorable foundation for more advanced chemistry and cultivating a genuine spirit of scientific inquiry.
