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 fact sheet describes oxyfuel combustion, the technology that burns fuel in almost pure oxygen. Because this makes it easier to capture carbon dioxide from flue gas, there is the potential to achieve near-zero carbon dioxide emissions from the production of coal-fired electricity. A diagram illustrating this process ...

This interactive activity allows students to explore the processes involved in the mining and processing of copper ore and the production of copper. Students initially put the processes in the correct sequence and then select each stage to animate it and access relevant information. The smelting stage includes an activity ...

• TLF-IDM008838

This is a fact sheet providing information on how we produce hydrogen from fossil fuels and renewable energy sources. The uses of hydrogen are briefly discussed and information is provided about hydrogen fuel cells.

• TLF-IDM015345

This resource describes research into environmental disease resulting from the heavy metal mercury. It is estimated 60,000 babies are born each year in the United States with mercury-related diseases from the burning of coal in power stations. World wide, this is a significant problem. Mercury also enters the environment ...

• TLF-IDR6881

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.

• TLF-IDM020384

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 ...

• TLF-IDR6854

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).

• TLF-IDR6884

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.
