NZC Achievement Objectives: Material World

Level Four

• Group materials in different ways, based on the observations and measurements of the characteristic chemical and physical properties of a range of different materials.
• Compare Chemical and Physical change
• Begin to develop an understanding of the particle nature of matter and use this to explain observed changes.
• Relate the observed characteristic chemical properties of a range of materials to technological uses and natural processes.

Level Five

• Investigate the chemical and physical properties of different groups of substances, for example, acids and bases and metals.
• Distinguish between pure substances and mixtures and between elements and compounds.
• Describe the structure of the atoms of different elements.
• Distinguish between an element and a compound, a pure substance and a mixture at a particle level.
• Link the properties of different groups of substances to the way they are used in society or occur in nature.

Level Six

• Identify the patterns and trends in the properties of different groups of substances, for example, acids and bases and metals.
• Explore factors that affect chemical processes
• Link atomic structure to the organisation of the periodic table.
• Distinguish between atoms, molecules, and ions (includes covalent and ionic bonding)
• Use particle theory to explain factors that affect chemical processes
