There were lanterns to light and spectra to study. There were rocks to recognise and molecules to make. You could find out about flowers for native bumblebees, or make a foam fossil fish. You could learn about life with microbes and build your own model bug.You could try to navigate the Northwest Passage, or steer a Mars Rover. You could join the Supertasters, or play the Foodprint game. You could see 3D printing in action. The King Street Halls were packed with activities and people for the 2015 Family Day.
