Common misconception

Children may instinctively classify objects by observational similarities or through knowledge of use rather than by the material from which the objects are made.

Clear explanation of how properties of materials make them suitable or unsuitable for a particular purpose.

Give the children a variety of materials to explore so they can discover their properties first-hand. There are videos online that show the brittle nature of glass which is a safe way to demonstrate this property.
