Curriculum content descriptions

The atomic structure and properties of elements are used to organise them in the Periodic Table (ACSSU186)

Elaborations
  • recognising that elements in the same group of the periodic table have similar properties
  • describing the structure of atoms in terms of electron shells
  • explaining how the electronic structure of an atom determines its position in the periodic table and its properties
  • investigating the chemical activity of metals
ScOT terms

Properties of matter,  Atoms

The Reactivity Series of metals

Students use this simulation to investigate the differences between potassium, sodium, iron and gold in reactivity with water in the construction of a bridge. Teachers have to explain how the reactivity series of metals can be determined by considering their reaction with oxygen, water and acid, and how to use the reactivity ...

Interactive

Sites2See: Light and Matter

Links to resources to explore fundamental questions about light and matter and the application of the physics of light and matter to the past, the future and to space. Includes a quick quiz, links to additional DEC NSW physics resources and to the International Science School at the University of Sydney.

Displacement Reactions

Students use this interactive to test five metals in an iron sulfate solution to see if a reaction will occur and understand that more reactive metals such as magnesium, aluminium and zinc will displace less reactive ones such as iron from their compounds.

Gold nugget

This is a gold nugget (approximately 3.4 cm x 2.2 cm), which was probably found in about 1865 on a goldfield in Otago (in the southern South Island of New Zealand).

Male and female thylacines, 1841

This is a 36 cm x 55 cm hand-coloured lithograph of a pair of thylacines (‘Thylacinus cynocephalus’), commonly called Tasmanian tigers, against a background of small bushes and an open plain.

Zygomaturus fossil skeleton

This is a colour photograph of a 'Zygomaturus tasmanicus' fossil skeleton. The skeleton is a museum specimen and has been braced with metal rods. It is displayed in a standing posture.

Image

Phar Lap's skeleton

This is the skeleton of Phar Lap, the famous racehorse, which was born in New Zealand, raced mostly in Australia and died in unexplained circumstances in the United States in 1932.

Southern gastric brooding frog

This is a colour photograph of a preserved southern gastric brooding frog ('Rheobatrachus silus'). It is a museum specimen viewed from the front.

Image

Hydrogen molecule

This is a colour image of a model of a molecule of hydrogen, H₂. In this model, two hydrogen atoms are represented by grey-white spheres held together by a grey rod that represents a covalent bond.

An exhibition home made of fibrolite, c1930s

This is a black-and-white photograph of the exterior of an exhibition home made of fibrolite (fibro-cement) that was constructed by James Hardie and Co Ltd (now known as James Hardie Industries). The street outside the home is crowded with people, some of whom have come to view the fibrolite home. The photograph measures ...

Image

Oxygen molecule

This is a colour image of a model of a molecule of oxygen, O₂. In this model, two oxygen atoms are represented by red spheres held together by grey rods that represent a double covalent bond.

Image

Iodine molecule

This is a colour image of a model of a molecule of iodine, I₂. In this model, two iodine atoms are represented by deep red spheres held together by a grey rod that represents a covalent bond.

Image

Trilobite fossil

This is a colour photograph of a fossil trilobite of the genus 'Kolihapeltis'.

Climate science analysis from The Conversation

This is a collection of articles about climate science. It includes articles about modelling, explanations about heat trends, predictions about sea level rise, and why the science about climate change is clear. The articles are written in plain language and are authored by experts from universities in Australia and around ...

Image

Ethanol molecule

This is a colour image of a model of a molecule of ethanol, CH₃CH₂OH. In this model, atoms are represented by coloured spheres held together by grey rods that represent covalent bonds. The molecule contains two carbon atoms (the black spheres), one oxygen atom (the red sphere) and six hydrogen atoms (the grey-white spheres).

Image

Bromine monofluoride molecule

This is a colour image of a model of a molecule of bromine monofluoride, BrF. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The bromine monofluoride molecule contains one bromine atom (the brown sphere) and one fluorine atom (the blue-grey sphere).

Graptolite fossils - item 5

This is a colour photograph of a graptolite fossilised in rock. This species is 'Clonograptus persistens'.

Image

Graptolite fossils - item 1

This is a colour photograph of graptolites fossilised in rock. These are specimens of 'Pendeograptus fruticosus'. The figures visible on the rock are cataloguing numbers.

Image

Gastropod fossil

This is a colour photograph of a fossil of a gastropod 'Tenagodus occlusus', showing the spiralled shell.

Image

Thylacine pup

This is a colour photograph of a preserved underdeveloped thylacine pup ('Thylacinus cynocephalus'). It is a museum specimen preserved in a glass container. Museum cataloguing labels are visible.
