Effects of gravity

Students use this resource consisting of one page with diagrams of Mars, Earth and Jupiter. Students can select any combination of planets and then 'drop' the crates to note the effects of the different gravity forces because of the different masses of these planets. Students should be able to conclude that gravity is a ...

Aerial Orang Utans

This 11 minute video segment form Catalyst shows that although the orang-utans of Borneo are threatened with extinction, we don't know exactly how many are left or where they are. The use of helicopters to locate their nests and estimate population size has helped to challenge our thinking about the requirements of this ...

Giant Cuttlefish

This 12 minute video segment from Catalyst outlines the fascinating and unique features of the giant cuttlefish and its mass breeding at Point Lowly. Then it explains how scientists have determined the vulnerability of this species- the fact that the eggs are sensitive to high levels of salinity and the fact that they die ...

CMT disease

This seven and a half minute video segment from Catalyst describes CMT (Charcot-Marie-Tooth disease) is Australia's most common genetic neurological disorder. Vitamin C, particularly when taken at a young age appears to reverse this effect. A good example of the scientific method.

Cloud seeding

This nine and a half minute video segment from Catalyst describes how researchers from Monash University have hard evidence that cloud seeding can produce good amounts of extra rainfall. Data collected over a long period of time has give hope to scientists and environmentalists who are trying to reduce the impacts of droughts ...

The Circulatory System: Heart animation

This resource allows students to 'resuscitate' a patient by dragging and dropping the main parts of the heart to their correct position. Incorrect positioning results in death! When organs are correctly positioned, the patient commences breathing and the heart beating and the structures are labelled. Note this resource ...

Too cold for cane toads

A new study reported in this video segment has looked at how temperatures impact cane toad movement and has aided in the development of a model that indicates that their geographical spread is limited. An excellent example of the use of mathematical modelling in scientific research and how scientists have tried to address ...

Future of the moon

This 4 minute video segment from Catalyst describes how Moon rocks may hold clues about the beginnings of life on Earth because of the lack of weathering and erosion.

Coal Gas

This 12 minute video segment from Catalyst outlines how for decades, scientists have worked to develop technologies that can unlock the energy from coal while reducing the risks of digging it up and burning it. Now entirely new industries are booming as they tap into coal seams either too gassy or too deep to be mined by ...

Ancient Resurrection

This 8 minute video segment from Catalyst highlights what is needed to resurrect ancient species, and raises the question whether we should. It also demonstrates the impacts of technology.

Cracked soils

This brief video segment from Catalyst demonstrates how scientists have developed probes to measure the water content of soils and therefore monitor the effectiveness of irrigation and the efficiency of water usage.

Exoplanets

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 ...

Borneo Live Reef Fish Trade

This nearly 13 minute video segment from Catalyst explains how Fisheries scientists warn that if fishing around the world continues at its current pace, more and more species will vanish. The coral triangle is one particular area where biodiversity is at risk, and the top predator appears to be humans.
