See how scientists such as Ernest Rutherford have investigated the structure of atoms. Explore possible models. Fire charged particles at atoms and find which model best fits the results. This learning object is one in a series of six objects. Three of the objects are also packaged as a combined learning object.
This ABC article by Dr Karl addresses the question: will we one day be able to power cars with water? The chemical reactions involved in the formation and decomposition of water are described. Energy transformations are explained. A very useful resource to get students thinking.
This simulation allows students to explore the chemical reactions between hydrogen, oxygen, carbon, nitrogen and chlorine. They can form water, carbon dioxide, hydrochloric acid, ammonia and methane. Word and chemical equations are provided. The diagrams distinguish single, double and triple bonds and shapes of molecules.
Students use this resource consisting of seven slides with diagrams, written explanation and voice-over to understand how to prepare a neutral salt sample using an acid and an alkali. There is a two-question quiz and a summary slide.
Climate change was once just part of the science domain, but today it is a political juggernaut! This unit explores the science of climate change as a scientific concept and a political issue. The unit includes PDF resources and video quiz challenges for teachers and student and the library section provides extra resources ...
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.
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).
This interactive resource takes students on a journey of discovery in the energy and mining world. Oresome world contains five games or modules: Coal, Energy, Gas, Low emissions and Mining, and within each of these there are several facilities to explore, such as the Underground mining site, Hydroelectric power station, ...
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.
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).
This is a colour photograph of a fossil trilobite of the genus 'Kolihapeltis'.
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.
These seven learning activities, which focus on 'visual representations' using a variety of tools (software) and devices (hardware), illustrate the ways in which content, pedagogy and technology can be successfully and effectively integrated in order to promote learning. In the activities, teachers assist students to understand ...

This is a colour photograph of a fossil of a gastropod 'Tenagodus occlusus', showing the spiralled shell.
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.
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.
This is a colour photograph of a preserved southern gastric brooding frog ('Rheobatrachus silus'). It is a museum specimen viewed from the front.
This is a colour photograph of a graptolite fossilised in rock. This species is 'Clonograptus persistens'.
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.
