Year 10 Chemistry: Rates of Reaction
This term, our Year 10 students delved into the fascinating world of chemical kinetics. They explored the factors affecting the rates of reactions, such as temperature, concentration, surface area, and catalysts. Through engaging experiments, students observed how altering these factors could speed up or slow down reactions, providing them with a practical understanding of the collision theory. Highlights included a dramatic demonstration of the "elephant's toothpaste" experiment, showcasing the rapid decomposition of hydrogen peroxide catalysed by potassium iodide.
Year 10 Biology: Excretion and Coordination
In biology, our Year 10 classes have been busy studying the human body's vital processes of excretion and coordination. Students learned how the kidneys filter blood, remove waste, and regulate water balance through urine production. They also examined the liver's role in detoxifying chemicals and producing bile. In the coordination segment, students explored the nervous and endocrine systems, understanding how these systems work together to maintain homeostasis. Hands-on activities included dissecting a kidney to observe its structure and nerve simulations to illustrate how nerve impulses travel through neurons.
Year 7 Biology: Food Chains and Food Webs
Our Year 7 students began an exciting journey into ecosystems, studying food chains and webs. They learned about the interdependence of organisms, starting with producers like plants and algae, moving up to primary consumers, and ending with apex predators. The students created their food web diagrams, highlighting the complex relationships between different species in an ecosystem. They also discussed the impact of human activities on these delicate balances and brainstormed ways to protect our natural environments.
Overall, it has been a productive and enlightening term for our science students, filled with hands-on experiments, engaging discussions, and a deeper understanding of our world's natural and chemical processes. We look forward to continuing this journey of discovery next term!
