• TLF-IDM016448

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 ...

This six and a half minute video segment from Catalyst explains Earthshine as light from our own Earth reflected back from the Moon's dark side. A PhD student is studying it to learn about how light reflects from a planet that contains liquid water as well as land. Her work may one day lead to the discovery of other planets ...

• TLF-IDM016619

This 7 minute video segment from Catalyst outlines the impact of the work of Charles Darwin on specific Australian scientists and as such addresses aspects of the nature and history of science.

• TLF-IDM016623

This seven and a half minute video segment from Catalyst emphasises the importance of collections in science. The Royal Botanic Gardens is the oldest scientific research organisation in Australia. The history of the gardens is outlined up to its current status as the home to almost 9,000 different species of plants. Paul ...

This five and a half minute video segment from Catalyst demonstrates how tagging is being used to study populations of sea dragons. The Weedy Seadragon is one of the most visually striking creatures in the sea but we still have a lot to learn about them.

• TLF-IDM016644

This six and a half minute video segment from Catalyst shows one of the most beautiful and bizarre creatures under the sea, the seahorse. Their highly unusual reproduction has not been sufficient to overcome the impacts of habitat destruction and human predation.

• TLF-IDM016678

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.

• TLF-IDM016772

This nine and a half minute video segment from Catalyst explains that relatively recently times we have got the technology to look for exoplanets. Astronomers have now uncovered more than 350 planets orbiting other stars. These worlds, known as exoplanets, can be pretty weird places. This program discusses a theory to describes ...

• TLF-IDM016391

This 7 minute video segment from Catalyst describes the risk factors that impact on turtle survival. Protecting the future of turtle populations on the Queensland coast has been the life's work of Col Limpus for the past 40 years. His efforts have included research and reducing predation from foxes and entrapment in trawler nets.

• TLF-IDM016134

In this simulation students select to measure the voltage across one, two or three light bulbs in series to measure the voltage drop across one, two of three bulbs.
