Scientists represent their ideas in a variety of ways, including in complex diagrams and models. In order to interpret what a representation is showing, we need to understand the conventions that are used in that representation. We also need to be aware that a representation, including a diagram, is designed to highlight a particular aspect, and in doing that other information is omitted or not focussed on.
Understanding and using the literacy practices of science supports students to think in new ways and supports students to become scientifically literate, i.e., to participate as critical, informed, and responsible citizens in a society in which science plays a significant role. (This is the purpose of science in NZC.)
