• TLF-IDM016120

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 ...

• TLF-IDM016379

This 6 minute video segment from Catalyst explains how the dugong, a vulnerable to endangered species is protected and that very little is known about it. Biologists are capturing animals to get baseline information about their blood and tissues in an effort to find out more about them and to secure their future. They are ...

• TLF-IDM016221

This resource is in the style of an 'authentic' scientific investigation. The investigation is set in a crime lab where finding the densities of the various items can solve the crime. The tool enables students to explore mass and volume for a variety of solids and liquids and hence determine their densities.

• TLF-IDM016612

Students use this resource consisting of one page with a diagram of a lever whose length can be varied. A weight is then applied to the lever and students can see whether the force was sufficient to lift a crate. This demonstrates that forces can cause a lever to turn about a pivot and that the turning effect of a lever ...

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-IDM016358

This 8 minute video segment from Catalyst is an excellent example of animal behaviour of locusts as a successful adaptation and how understanding the behaviour can potentially help reduce the damage they cause.

• TLF-IDM016196

In this simulation students select an object made of one of two materials (either iron or aluminium) and use magnets to guide the object through a maze. Engages students while they learn that aluminium is not attracted to magnets but iron is.

• TLF-IDM016574

This simulation allows students to change the temperature and observe the changes at macro and micro level to water. It reinforces the Particle Theory.

• TLF-IDM016244

This 7 minute video segment from Catalyst describes an excellent example of how biologists have worked to investigate and solve a problem of an invading species of sea urchin that was devastating a marine ecosystem. The scientific approach to develop a biological control needed to rely on technologies such as radio tracking ...

• TLF-IDM016769

A simple interactive simulation in which students compare probabilities.
