In this chapter metaphors and related figures of speech are shown to be necessary and integral parts of sense making and learning. It is shown how this kind of speech has been studied in research in relation to children’s understanding and learning. It is argued that different methodological approaches have led to different notions of children’s abilities. Two recent studies on children and metaphorical speech in science-learning activities in preschool are introduced. One study investigated the nature and use of such speech and another study looked at a particular form of metaphorical speech, anthropomorphism. It is argued that metaphor is one way of establishing relations between different things without collapsing them into one and the same.
