Grade 10 MYP Biology Students Shine
with Innovative Enzyme Experiments
In an impressive display of scientific inquiry, Grade 10 MYP Another notable experiment focused on liver as a source of Biology students have recently completed a series of fascinating experiments focusing on the action of enzymes, a fundamental topic in biological studies. This task marked the culmination of their experimental skills development in the Middle Years Programme (MYP) and provided a platform for each student to conduct their own unique investigation.
catalase. This project explored how different concentrations of hydrogen peroxide affect the rate of breakdown, providing insights into the enzyme's behaviour in different substrate concentrations, an essential aspect of enzyme kinetics. Students who explored other enzymes, such as pepsin and amylase, designed experiments to observe the digestion of proteins and starch, respectively. These experiments not only reinforced the students' understanding of enzymatic activity but also highlighted the practical applications of enzymes in biological systems.
The objective set for the students was to design and carry out an experiment investigating the mode of action of one of several key enzymes: catalase, pepsin, trypsin, lipase, or amylase. With a variety of options available, students had the freedom to choose their enzyme of interest and explore deeper into its biochemical The success of these experiments is a testament to the rigorous mechanisms. scientific training provided by the MYP Science curriculum. Both A significant number of students chose to explore the enzyme teachers and technicians are immensely proud of the creativity, catalase, which plays a crucial role in catalysing the breakdown dedication, and scientific acumen displayed by the students. of hydrogen peroxide into water and oxygen, a vital reaction This project not only enhanced their understanding of biochemthat prevents cellular damage. Each student selected a different ical processes but also equipped them with critical thinking and source of catalase, including yeast, potatoes, liver, and other analytical skills that are essential for their future academic and innovative materials, to compare its effectiveness in speeding up career pursuits. the reaction. As these young scientists continue to build on the strong The students meticulously measured the rate of oxygen production as a marker of enzyme activity, under various conditions to understand the enzyme's efficiency at different temperatures and pH levels.
