Science at key stage 3    (Year 9)

• that metals are good conductors of heat and electricity
• that most non-metallic elements are poor conductors of heat and electricity
• about the range of metals, their uses and where they are found
• to use and combine data from a variety of information sources
• to organise facts/ideas/information into an appropriate sequence

• that some metals react with dilute acids to form salts and release hydrogen
• to carry out a test for hydrogen
• to represent the reactions of metals with dilute acids by word equations
• to identify patterns in reactions between metals and dilute acids
• to use patterns in reactions to make predictions about other reactions

• that acids react with metal carbonates, producing carbon dioxide and a salt
• that production of new materials and energy changes are evidence of chemical reactions

• that acids react with metal oxides, producing a salt and water
• that production of the salt is evidence of a chemical reaction
• to represent reactions of acids with metal oxides by word equations

• to summarise how acids react with metals, metal carbonates and metal oxides

• that when an alkali is added to an acid, neutralisation takes place
• how to obtain a neutral solution from an acid and an alkali
• the hazards associated with alkalis

• that there are many different salts
• that many salts are useful compounds

• to use preliminary work to find out if a possible approach is practicable
• to use common laboratory equipment safely and effectively
• to evaluate the methods used in terms of the quality of the salt made
• to organise content into a piece of writing, with the relationship between paragraphs clearly signalled

• to identify key points about the reactions of metals and acids
• to identify patterns in the chemical reactions
