The atomic structure and properties of elements are used to organise them in the Periodic Table (ACSSU186) o Discovering ideas: Memory tricks o Navigating the periodic table. Communicating Communicate scientific ideas and information for a particular purpose, including constructing evide nce-based arguments and using appropriate scienti fic language, convent ions and representations (ACSIS208) See: Discovering ideas: Memory tricks Science as a human endeavour (embedded throughout all chapters) Nature and development of science Scientific understanding, including models and theories, are contestable and are refined over time through a process of review by the scientific community (ACSHE191) General capabilities and crosscurriculum priorities Possible teaching strategies Assessment Extra resources Achievement Standards Critical and creative thinking See: o Discovering ideas: Memory tricks Remembering the chemical symbols for elements on the periodic table is important for students who plan to continue science studies. A good way to do this is Periodic Table Bingo. Many templates are available for free on the internet and students enjoy the game whilst learning the chemical symbols. Teachers can check that students understand how to read the periodic table through questioning or a simple worksheet leaving parts blank for students to fill in. It can be good to have samples of various elements to show students in class. Most schools carry a stock that can be used. Students can analyse how the periodic table organises elements and use it to make predictions about the properties of elements. See: Getting elements organised (and timeline). Oxford Big Ideas Science 10: Australian Curriculum ISBN 978-0-19-557709-9 Students can choose five elements to research and present a short PowerPoint presentation to the class detailing general information including the uses of each. © Oxford University Press Australia Many templates for Periodic Table Bingo are available for free on the internet.

A formal experiment for Experiment 6.1: Reactivity of metals could be submitted. There are many examples of black and white periodic tables available online which can be used as a colouring in sheet for students to identify and colour the various groups of elements. Students can analyse how the periodic table organises elements and use it to make predictions about the properties of elements. See: Groups of elements and their uses. Oxford Big Ideas Science 10: Australian Curriculum ISBN 978-0-19-557709-9 Classroom discussion on the characteristics shared by groups and how the characteristics affect the use of these elements. For example, irons strength and malleability. The activity Overarching ideas: Extreme Halophiles can be done as a formal research report utilising inquiry-based learning. © Oxford University Press Australia It can be good to have samples of various elements to show students in class. Most schools carry a stock that can be used. 2 Section Science understanding Learning experiences Science Inquiry skills (embedded throughout all chapters) 6.3 How are properties linked to atomic structure? The atomic structure and properties of elements are used to organise them in the Periodic Table (ACSSU186) o Discovering ideas: Explaining differences in reactivity o Practivity 6.1: Identifying patterns in the periodic table o Experiment 6.2: Conductivity of ionic compounds o Skills lab: Ionic compounds Planning and conducting See: o Experiment 6.2: Conductivity of ionic compounds Processing and analysing data and information See: o Experiment 6.2: Conductivity of ionic compounds Communicating See: o Experiment 6.2: Conductivity of ionic compounds Science as a human endeavour (embedded throughout all chapters) Nature and development of science Advances in scientific understanding often rely on developments in technology and technological advances are often linked to scientific discoveries (ACSHE192) General capabilities and crosscurriculum priorities Possible teaching strategies Assessment Extra resources Achievement Standards Personal and social competence See: o Practivity 6.1: Identifying patterns in the periodic table o Skills lab: Ionic compounds It can be good for students to create 3D models of atoms in order to memorise their parts. There are templates available online for paper atom mobiles (circles / shells connected by cotton thread). Many schools also have pre-made model kits that could be used. A formal experiment report for Experiment 6.2: Conductivity of ionic compounds. Molecule model kits (also can be done with plasticine). Students can analyse how the periodic table organises elements and use it to make predictions about the properties of elements. See: Electrons and electricity Group work. Inquiry-based learning. Oxford Big Ideas Science 10: Australian Curriculum ISBN 978-0-19-557709-9 A unit test that asks students to use the periodic table to draw electron configurations of a number of elements. Teachers can question students to ensure they understand what elements, atoms and ions are. This can also be done as a mind map with other key terms. © Oxford University Press Australia Templates for paper atom mobiles (circles / shells connected by cotton thread) are available online. 3
