What students learn in AC9S10U06
This unit helps students build a clear, usable understanding of Explain how the structure and properties of atoms relate to.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: explain how the structure and properties of atoms relate to the organisation of the elements in the periodic table.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- examining how elements are organised in the periodic table and analysing patterns to discern that elements in the same group of the periodic table have similar properties investigating the physical properties of some metals and non-metals
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- Content description: explain how the structure and properties of atoms relate to the organisation of the elements in the periodic table
- E1: examining how elements are organised in the periodic table and analysing patterns to discern that elements in the same group of the periodic table have similar properties
- E2: investigating the physical properties of some metals and non-metals
- E3: using the Bohr model of the atom to describe the structure of atoms in terms of electron shells and relating this to their properties and position in the periodic table
- E4: deducing that repeating patterns of the periodic table reflect patterns of electrons in outer electron shells
- E5: conducting flame tests for a selection of elements and examining emission spectra
- E6: examining how the development of the spectroscope led to further development of the model of the atom
How to use this unit
Read the topic guide, use the teacher slide for instruction, then complete the Worksheet, Practice and Test. These three activities use the same eight-question unit bank.

- Describing what is seen without connecting it to a question, pattern or prediction.
- Using everyday words only and missing simple scientific vocabulary.
- Changing more than one thing in an investigation, which makes the comparison unfair.
