Science
Across the year, our students cover all four core units of Science - Biology, Chemistry, Physics, and Earth Science. Speaking with your child, they will be able to tell you which two of the four units have been studied in they respective year this Semester. In case they have forgotten, these are listed below.
Year 7: Chemistry and Physics
Year 7 students described techniques to separate pure substances from mixtures, and represented and predicted the effects of unbalanced forces on motion.
Year 8: Biology and Physics
Year 8 students analysed the relationship between structure and function at cell, organ, and body system levels, and described how energy transfers and transformations cause change in simple systems.
Year 9: Biology and Earth Science
Year 9 students analysed how biological systems function and respond to external changes with reference to interdependencies, energy, and matter flow, and explained globla features and events in terms of geological processes and timescales.
Year 10: Biology and Chemistry
Year 10 students have explained the processes that underpin heredity and evolution, and have analysed how the periodic table organises elements and used this to make predictions about the properties of elements. They have also explained how chemical reactions are used to prodice particular products, and how different factors influence the rate of reactions.
This week, staff have been conducting fun and engaging science experiments with students. In the photo below, Ms Cabrera is performing the elephant toothpaste reaction, a demonstration of the reaction between sodium iodide and hydrogen peroxide. The sodium iodide reacts with the hydrogen peroxide (H2O2) by removing an oxygen atom. This essentially produces water and oxygen gas (H2O + O2). The oxygen gas produced gets trapped in the soap which produces the big ball of foam. The reaction produces oxygen gas, water and iodine.
