ORGANIC CHEMISTRY (weeks 1-2)
We will conclude our studies of organic chemistry.
There will be an external assessment opportunity (AS91391 - 5 credits).
OUR ENERGY FUTURE (weeks 3-7)
What's inside a battery? Let's find out! Come learn about the chemistry behind different types of batteries, and about the future of battery chemistry as the world looks for better batteries with higher energy density to power things like electric cars with even longer driving distances.
There will be an internal assessment opportunity (AS91393 - 3 credits).
WHAT'S THE MATTER? (weeks 8-10, concluding in Term 3)
This unit is all about understanding: the true nature of atomic structure according to our most up-to-date atomic models; the shape and geometry of molecules, and how that directly influences the macro properties of useful substances in our everyday lives; and how a more advanced understanding of enthalpy and entropy can help us easily predict beforehand whether a chemical process is likely to occur spontaneously ("Wow, that was a large explosion...") or not happen at all ("Aw, nothing happened...")
We will first study atomic structure, quantum mechanics, and electron configuration. We will then apply that knowledge to better understand periodic trends (electronegativity, ionisation energy, atomic and ionic radii).
On top of that, we will expand upon our Level 2 knowledge of 3-D VSEPR molecular shapes and intermolecular forces, and apply that knowledge to study substances with useful properties and recent applications in our society, such as superconducting materials, nanomaterials, integrated-circuit chips, polymers, fuel cells, and more.
Finally, we'll heat things up a bit and explore thermodynamics in exciting contexts, such as solid vs liquid fuel propulsion systems in the aerospace industry.
There will be an external assessment opportunity (AS91390 - 5 credits).
