What does 'horsepower' really mean? And how do engines work? Join Luke and Abhi from MIT to find out! As Abhi explains, engines produce power by forcing a mixture of fuel and air into a tight space and then burning it. Piston engines and turbine engines do this in similar, yet different ways. After watching this video, ...

Enter this virtual laboratory and conduct experiments to investigate genetic variation and evolution of populations of the three-spined stickleback fish. Students analyse fish and fossillised specimens, construct tables and graphs, and interpret their analysis. There are also instructive tutorials, videos describing stickleback ...

This is a video [6:05 min] about the production of ethanol from sorghum at the Dalby Bio-Refinery in Queensland. The video describes and illustrates the stages in the production process including milling the sorghum into ‘flour’; mixing the flour with water to hydrolyse the starch; adding enzymes to liquefy the starch (the ...

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).

Good question! Find out whether this is possible by watching as biologist at MIT, Dr Sera Thornton explains. What is a genome? And why do genomes need to be decoded? If the rhino genome was successfully decoded and the part that described the rhino horn was isolated, what would the process be for creating a unicorn?

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 ...
