Lesson 9Gc: Physical and chemical Material for revision National Curriculum statements Exemplar teaching activities 7F, 8G Chemical reactions C15: defining and alkalis in terms of C15: Ask students to suggest how to make spilled concentrated 8G, 9E, 9F Materials neutralisation reactions acid safe to be mopped up. C16: the pH for measuring C16: Ask students to design a quick test to find out how strong acidity/alkalinity; and indicators two unknown acids are. C17: reactions of acids with metals to produce a C17: Zinc reacts with sulphuric acid (H2SO4) to form zinc sulfate salt plus hydrogen (ZnSO4). Ask students to write a word equation and a symbol equation for the reaction. Then ask them to describe how they could obtain a solid sample of the salt. C18: reactions of with alkalis to produce a C18: Card sort with assorted names of five acids, five alkalis and salt plus water five salts plus five water cards. Ask students to sort the cards, including the water cards, into reactants and products of five neutralisation reactions. C28: the of metals and carbon in the C28: Card sort with assorted descriptions of reactions of metals reactivity series with acids. Ask students to arrange them in order of reactivity. C29: the use of carbon in obtaining metals from C29: Ask students what they know about extracting metals. oxides Provide them with a list of metals and ask them to decide if each one occurs as the native metal, or is extracted by heating its ore with carbon or by electrolysis of its molten ore. C30: properties of ceramics, polymers and C30: Ask students to write a paragraph on each of ceramics, composites (qualitative) polymers and composites, describing their properties. Lesson 9Gd: The periodic table Material for revision National Curriculum statements Exemplar teaching activities 7H, 8F The periodic table C22: the varying physical and chemical C22: Ask students to choose an element for a) wires in electrical 7H, 8H Earth and properties of different elements cables and b) powerful magnets to lift scrap steel, and describe atmosphere two properties that make it suitable for that use.
