SCIENCE Year 10 — 2012

Chemistry [Trimester Core]

Rationale

The Chemistry course has been designed to be accessible (at a conceptual level) to all students.  Students are asked to explore situations and knowledge that are taken from within their concrete experiences and from these, progress into explanations based on knowledge and understanding of Chemistry.  The course has a blend of theory and practice.  It provides a solid foundation for further study in Chemistry or other sciences and has the capacity to provide a stimulus for the advanced students and/or those with a special interest in Chemistry.

Student Outcomes

Unit 1:

• explain aspects of atomic structure
• write simple chemical formulae
• write balance chemical equations
• calculate formula masses and percentage composition by mass
• evaluate the usefulness of various chemical products in forming a pain

Unit 2:

• explain aspects of metal structure
• understand the nature of alloys
• describe what causes corrosion
• how protection from corrosion can be achieved
• understand how simple batteries work
• understand how objects can be electroplated to improve their usefulness

Course content 

The Search for the Perfect Paint: Composition of traditional and modern paints and the steps required to manufacture a new product:

• Preparation of pigments using four different reaction types.
• Atomic structure, electronic configuration and their relationship to the organization of the Period Table.
• Formation of ions and ionic compounds.
• Chemical formulae and the naming of compounds.
• Calculation of percentage composition and balancing equations.
• Preparation of paints from pigment and binders and evaluation of the product.

Metals:

• The properties and structure of metals and the relation to their uses.
• Application of the reactivity of metals to corrosion and manufacture of batteries.
• Corrosion of metals, particularly iron, and methods of corrosion protection.
• The structure of alloys and the effects of alloying on the properties of metals.
• Oxidation and reduction in terms of corrosion and extraction of metals from minerals.
• Case study:  Extraction of iron.
