As we near the end of our first semester with less the two weeks to go now, it is wonderful to see various projects and events showcasing the learning that has been occurring over the past semester. A few examples of note include:   

  • “Honk”, our production for 2023 based on the children’s story “The Ugly Duckling”. What a wonderful performance – congrats to the performers, organizers, stage crew, and audience! 
  • Book Week events – what an action-packed week to promote reading and literacy!
  • Various end-of-unit projects throughout the school.

These examples are a good reminder for us to be grateful for what we have, and can experience. It is interesting to note the research shows multiple benefits from being grateful, including a positive impact on health, well-being, and relationships. As we approach our mid-year Christmas break, let’s make an effort to be grateful, and share our gratitude with others. Our community will certainly benefit from this! Have a wonderful weekend!

Grade 11 and 12: DP Biology

by Ms. Rebecca Devadoss, DP Biology Teacher

Grade 11 Class
During the various metabolic activities within our cells, hydrogen peroxide is produced as a byproduct. If too much hydrogen peroxide builds up, it can cause damage. The enzyme catalase converts this harmful hydrogen peroxide into harmless water and oxygen, helping to keep our cells safe. Catalase works best at a temperature around our body temperature, which is about 37 degrees Celsius (37°C), and works in a slightly basic or neutral environment. The best pH for catalase activity is around 7.

This quarter, students explored the factors that affect the enzymatic activity of catalase in potato tissue using 3% hydrogen peroxide as the substrate. Students in groups investigated the effect of temperature or pH and measured the enzyme activity by the height of the oxygen bubbles that are produced as a byproduct. 

Fiana and Monica are getting the experimental setup organized.
The height of oxygen bubbles at different pH levels was measured.

The results were aligned with established scientific knowledge, validating the reliability of the experiment.

The Earth is a closed ecosystem where energy is transferred but matter is recycled. Energy flows through the trophic levels, sustaining life. Students set up innovative “mesocosms” that were either terrestrial, aquatic, or a combination of both. Mesocosms are closed ecosystems that are sealed to ensure that water, oxygen, carbon dioxide, and other nutrients are recycled. Plants initiate the energy transfer through photosynthesis. Decomposers that would be naturally present in the soil and water break down organic matter, completing the cycle. While the matter remains within the system, energy continually circulates, emphasizing the closed yet dynamic nature of Earth’s ecosystem. The mesocosm experiment exemplifies how, in Earth’s closed system, matter is conserved and energy sustains life.

Students have been making qualitative observations on a regular basis. Images of mesocosm.
