We caught up with Mr. Shah’s students during a Biology session which focused on determining the presence of starch in food samples. For this experiment, small portions of flour, fruit, vegetables and tubers were laid out. Normally yellow in color, diluted iodine drops were carefully applied to each food sample. If starch is present, students will observe the iodine turn dark blue.
During a recent chemistry experiment, students tested the reactivity of Sodium (Na), Potassium (K) and Lithium (Li) with water. The experiment was performed in a safety chamber behind protective glass while students wore safety goggles, gloves and lab coats as they handled the laboratory materials.
Secondary 4 student Law Dickson credits his sister for inspiring his interest in Biology and Chemistry, while classmate Koh Chen Xi saw the two science courses as a way to develop his ambitions as a chef. Chen Xi adds that he makes up funny names from the first letters of new concepts to help him remember information better.
Fellow student Naik Hsing Wei appreciates how both Biology and Chemistry have helped her better understand how life functions. To his credit, Mr. Shah has guided his students in their exploration of Biology and Chemistry as vehicles for understanding life around them.
