Typical misconceptions about changes of materials

Three misconceptions commonly held by children involving ideas around changes of materials are:

  1. A confusion between the processes of melting and dissolving.
  2. A belief that a solid disappears when it dissolves in a liquid.
  3. An incomplete understanding of irreversible reactions, for example thinking that the bubbles from a vitamin C tablet are in the tablet, rather than being produced by a chemical reaction when they are added to water.


Can you share one misconception that you have found when teaching children about materials and their changes.
