Checkpoint Science Scheme of Work Chemistry – Year 2 Topic: Atoms and elements Aims That pupils should be able to: give symbols to the common elements understand that elements are made of atoms Links Checkpoint curriculum – Cm 1, Cm2 IGCSE Chemistry 4, IGCSE Co-ordinated Sciences C 1, IGCSE Combined Sciences Chemistry Topic One, IGCSE Physical Science 3.1 Words element, atom, compound, chemical symbol Activities Objectives Students should be able to: Possible Activities Health and safety/notes explain what is meant by an element. Provide students with the spherical model of the atom. Explain that elements contain only one type of atom and therefore cannot be split into different substances. They have only one name. Discuss how they might be arranged in solids, liquids and gases. name the lightest twenty elements. Students are provided with a list of the names (or possibly samples in twenty tubes) of the lightest twenty elements, with picture / description. Give a definition of an element. research and present a profile of an element. An element can be chosen and its properties, uses and history researched to construct an ‘element profile’ to present to the class. identify some elements by their flame tests. Flame colours for elements can be observed. Safety goggles must be worn. Use dilute hydrochloric acid for cleaning and recommend using any sodium compounds last because of their www.xtremepapers.net

strong colour. learn the symbols of the first twenty elements The first twenty symbols must be learnt, students can test each other as a team game. e.g. “my symbol is the end of my footwear” Ans. sock = K = potassium “my symbol is a lot of water and a note” Ans. C and a = calcium Alternatively they can make up crosswords or wordsearches. explain the formation of simple compounds. Simple combinations of elements can be carried out, accompanying each with a word equation. E.g. burning magnesium or steel wool in air/ oxygen heating iron wool in iodine vapour Students can be given names/ samples of common chemicals and can identify the elements that they contain. Safety goggles must be worn. Introduce the term compound. This must be carried out in a fume cupboard.

Topic: Further Reactions Aims That pupils should be able to: explain the idea of compounds name some common compounds including oxides, hydroxides, chlorides, sulphates and carbonates use a word equation to describe a reaction Links Checkpoint curriculum – Cm 2, Cc1, Cc4, Cc7 IGCSE Chemistry 8.1, IGCSE Co-ordinated Sciences C 9, IGCSE Combined Sciences Chemistry Topic Four, IGCSE Physical Science 6 Words oxides, hydroxides, sulphates, carbonates, salts Activities Objectives Students should be able to: Possible Activities Health and safety/notes
