An experiment based on an Aesop's fable shows children and birds learn differently
An experiment based on an Aesop's fable has shown how differently children and crows learn about the world.
In the story, a thirsty crow drops pebbles into a pitcher of water. Eventually the water level rises high enough for the crow to drink.
Studies have shown that crows really do understand Archimedes's principle. Faced with a food reward floating out of reach in a flask, they will select weighty objects over light ones to displace the water and bring the food within reach.
