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 ...

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.

Light takes time to travel through space

Light travels in waves and carries information as it moves from one object to another. In this clip, people are used to represent the Sun, planets and light rays in order to show that light takes time to travel through space bringing information from those objects to us on Earth. Discover that by the time we receive this ...

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?
