This 8 minute video segment from Catalyst shows how research can also help us to optimise our health, especially into older age. It describes an example of how sometimes research gives us mixed messages. Sun exposure helps our body to produce the hormone, vitamin D but it also increases incidence of melanoma.

This 13 minute video describes how science supports archaeology. Dr Paul Willis follows a group of Australian volunteer archaeologists as they unravel the complex archaeology of the Atacama Desert in Chile and find mummies that were made thousands of years before the Egyptian civilisation started. How scientific ideas and ...

Students use this simulation to learn that react with hydrochloric acid to produce salt and hydrogen and find out how to test for hydrogen gas. The notice that sodium reacts violently and that magnesium reacts more quickly than zinc but that the hydrogen gas test is positive for both. Word equations are provided for all reactions.

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 ...

In this resource students explore how an electromagnet works in real life. They can then apply their learning in an electromagnetism game by changing the magnetism of a scrap lifter in a scrap yard and removing various amounts of scrap. The resource demonstrates the connection between the power applied, the number of coils ...
