Properties of liquid and gas

Nitrogen gas makes up 80% of the air we breathe, and if we cool the nitrogen gas down to minus 196 Celcius and squash it down we can turn it into liquid nitrogen. This liquid takes up much less space than it did as a gas. When we warm up liquid nitrogen it will turn back into a gas and take up more room, so what happens ...

Energy chains: make electricity

Build up to six energy chains that make electricity. Select from different energy sources and choose energy converters to match. Examine the type of energy change that happens in each converter. Arrange the converters into the correct chain so that the energy can be delivered as electricity. For example, construct a chain ...

The bang behind fireworks!

Ever wondered how fireworks are created? In this clip, pyrotechnics expert John Conkling describes the chemical and physical components of fireworks, and demonstrates many coloured explosions in a laboratory. Discover that a fireworks display is a chemical reaction between an oxidiser such as potassium nitrate and a fuel ...

Drugs may contain a 'biological calling card'

Illegal drug producers may leave behind DNA in the drugs they manufacture. This 'biological calling card' can then be used to locate and identify suspects. Find out how a South Australian scientist was able to extract DNA from a sample of drugs seized from a police drug-trafficking operation. Discover the new technique ...

'Junk DNA' not junk after all

Geneticists have long thought that 98 per cent of human DNA was 'junk' (or 'non-coding') DNA. However, recent scientific research suggests that there is much more to this DNA than first thought. Watch this clip to discover more.

Precious metals

Why are some metals prized more for jewellery than others? Listen to presenter Bernie Hobbs explain the chemical reaction that affects the look and durability of metals. Using the periodic table and some dazzling computer graphics, Bernie demonstrates why 'oxygen-proof, low-reactivity, transition metals' such as gold keep ...

Cells and energy

Cells are like chemical factories. Discover the different ways cells get energy to carry out their daily operations. Learn about the different types of metabolic processes inside cells, such as those that break down molecules to release energy and those that assemble building blocks to make more complex components.

Could you make a unicorn by crossing DNA?

Good question! Find out whether this is possible by watching as biologist at MIT, Dr Sera Thornton explains. What is a genome? And why do genomes need to be decoded? If the rhino genome was successfully decoded and the part that described the rhino horn was isolated, what would the process be for creating a unicorn?
