Air quality monitoring stations

Junior scientist Alexi demonstrates the science behind water currents. Currents occur when different temperatures (thermal energy) interact and change each other's density, which causes movement. To create your own water current experiment, you'll need a transparent plastic tank or container, two different food dyes, a small narrow-necked bottle, and an adult.

RMIT's Alex Fisher and Abdulghani Mohamed explain how the flight of birds inspired the development of their autonomous soaring drone, which uses updrafts to help power the flight.

Junior scientist Alexi uses a plastic container, food colourings and a bottle to create a water current model to demonstrate the effect temperature has on water pressure and creates currents.
