This week, our Grade 11 IBDP Biology students engaged in an exciting hands-on investigation exploring enzyme activity, specifically focusing on catalase and hydrogen peroxide. The primary objective was to measure the rate of enzyme activity by counting the number of oxygen bubbles produced during the reaction. This classic experiment allowed students to delve into biochemistry principles while enhancing their understanding of how enzymes function as biological catalysts.
Students worked in collaborative groups, fostering teamwork and honing their inquiry skills as they formulated hypotheses, designed experiments, and gathered data. The procedure involved mixing hydrogen peroxide with a source of catalase—typically found in yeast or potato—while observing the resulting effervescence. By counting the oxygen bubbles produced over a minute, they quantified enzyme activity under varying conditions, such as temperature and pH.
The hands-on nature of the experiment encouraged students to ask questions and draw conclusions based on their observations. Feedback indicated their excitement in witnessing the rapid production of bubbles and a newfound appreciation for the complexities of enzymatic reactions. This investigation exemplifies our commitment to fostering an engaging, inquiry-driven learning environment, and we look forward to more experiments that inspire our students to explore the wonders of biology. Stay tuned for updates!
