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.

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 ...

This 5 minute video segment from Catalyst shows a field trip with Dr Conrad Hoskin who has been scouring the tropical rainforests of north Queensland for frogs. He explains his research and the links between classification or taxonomy and evolution.

• TLF-IDM016121

This is a problem-solving activity in which students are engaged in a challenge is to control virtual bridges using expansion and contraction so that a car can pass over them. In so doing they learn about the expansion of solids, liquids and gases when heated is applied. Students need to understand how a bimetallic strip works.

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 6 minute video segment from Catalyst is an excellent introduction to the science behind photovoltaics. A useful comparison of the efficiency of energy conversion. Discussion of other issues considered in producing devices to use renewable energy to make electricity.

• TLF-IDM016786

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 ...

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 ...
