The nature of the artefact may change several times during making. Making is intuitive. The final product may bear little or no resemblance to the object in real life. Child has no idea about the majority of the design criteria in advance. Child also begins to form views about some or all of the essential characteristics of the making process though the final product may vary from them.
Child draws a picture of what is to be made and begins to label the key parts.
The picture on represents' what is to be made. The picture is not a 'plan', and the child can't necessarily make a model to this specification. Making is really continuing as in stage 3, as 'actual' materials to be used and other criteria are unknown. Child sketches ideas or models materials to establish the basic shape of what is to be required. Child makes a working drawing of this.
