The children realized that when they aimed the hot air from the dryer at the crayons, the heat melted the crayons. Drawing on past experience melting ice, the children came to the conclusion that the crayons were a solid that turned to a liquid when heat was applied.
As the wax melted, the colours mixed together and created beautiful designs. When the heat was not applied, the wax hardened and drip marks were visible on the cardboard.
The children also made some wonderful connections between what they saw in the artwork and their past experiences. Many children thought the crayon art looked like fireworks or a sunset.
