Solomon Islands Science Year 9.3 Materials:

General Learning Outcomes Specific Learning Outcomes
9.3.1 know that metals, semi-metals and non-metals have their unique properties (k) identify the different properties of metals: hardness, malleability, ductility, density and conductivity identify properties of Non-metals as: poor conductor, dull, brittle, low melting and boiling point. state that semi-metals have both metallic and non-metallic properties

9.3.2 be able to show that the corrosion of metals is caused by environmental factors (s) demonstrate the corrosion process using iron nails in conditions e.g.

i. iron nail in water

ii. iron nail in oil

iii. iron nail in air

9.3.3 be able to show rates of reaction between dilute acids (s) perform reaction between metals and dilute acids and compare the rate of reactions.

metal: Na, Mg, Al, Ca, Fe and Zn

dilute acids: Hydrochloric acid, Sulfuric acid and Nitric acid. [O.1M]

Use any acid that is available

9.3.4 know the different uses of alloys in the community (k) identify different types of alloy materials found around the school and community and state:

i. what metals they made of

ii. uses of the alloys

9.3.5 know the two main types of plastics (k) state the two main types of plastics:

i. thermoplastic

ii. thermosetting plastic state the materials used to make the plastics

9.3.6 be able to show examples of plastics (s) display the two types of plastic: thermoplastic and thermosetting plastic draw the structures of the two types of plastics

9.3.7 be able to show examples of fibres (s) display different kind of textile fibres: cloths and wool
9.3.8 appreciate the different uses of plastics in the community (a) express the advantage and disadvantage of the uses of plastics
