Many natural products, such as red cabbage and turmeric, can be used as a natural source of colour to dye fibres. Watch the dyeing demonstration in this clip to see how. Discover the chemistry of natural dyes, including the bonding properties of different pigments and how acid-base reactions can alter the colour of pH-sensitive ...

View how scientists use underwater sound waves to measure ocean temperature changes in the Indian Ocean. The animations show how the technology called acoustic thermometry works. Australian scientists are working with a global network of 'listening posts' to monitor the long-term effects of climate change on ocean temperatures.

Visit the world's largest nuclear fusion reactor, which uses the same process as the Sun to produce energy. Look at the new advances in fusion technology which mean, for the first time, a fusion reactor should now be able to produce more energy than it consumes. It offers a future alternative energy source, but is not without ...

See how genes and genetic engineering work. Build models of DNA, and work out how it is copied as cells divide. Discover how the codes carried in the genes are copied and used to build proteins. See how gene splicing can be used to benefit human lives. For example, model the transfer of a human gene into bacteria, so they ...

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.

• 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 ...

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 ...

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy. This TedEd animation (4:58 ...

Explore how chemical pollutants affect the Antarctic food web. A scientist shows that baleen whales are consuming Antarctic krill contaminated by accumulated residues of persistent organic pollutants (POPs) from pesticides and industrial chemicals. Find out why these pollutants are concentrated at the Earth's polar regions.
