Organ Pipe

This activity invites students to make a model organ pipe and explore how to amplify a tuning fork by holding it over the pipe and changing the length of the pipe. They investigate how at certain pipe lengths, the pitch made by the tuning fork sounds very loud as it resonates with the air column in the pipe. The activity ...

How does the retina work?

When electrons in your retina absorb photons of light they don't emit light, they cause a molecule to change shape - and that lets you see colour!

BTN: The biggest radio telescope in the world

In the past, astronomers explored the universe with their eyes and optical telescopes, but what they could see was limited. Find out how radio telescopes have revolutionised the way astronomers 'see' the universe, allowing us to explore deeper into space than ever before.Watch this clip to learn about Australia's contribution ...

The physics of invisibility cloaks

Could an invisibility cloak actually work? Prashanth and Maria from MIT explore this idea and demonstrate the cool ways that light bounces, bends and mixes. How do the wings of the Morpho Butterfly give clues about how an invisibility cloak could work? How would light need to be channelled in order for something to seem invisible?

ABC News: Sound waves measure ocean temperatures

View how scientists use underwater sound waves to measure ocean temperature changes in the Indian Ocean. The animations show how the technology called acoustic thermometry works. Australian scientists are working with a global network of 'listening posts' to monitor the long-term effects of climate change on ocean temperatures.
