Long description

A concept map for ‘water’ is shown. There is a series of text boxes linked by single headed arrows, with text labels running beside the arrows. A text box at the top which reads ‘water’ is linked directly by an arrow labelled ‘is made of’ to a text box with ‘molecules’ written in it. From ‘molecules’ one arrow labelled ‘are made of’ points to a box labelled ‘atoms’, and a second arrow labelled ‘have’ leads to ‘heat energy’. ‘Atoms’ also has an arrow labelled ‘have’ which leads to the same ‘heat energy’ box. From the ‘water’ box at the top, another arrow labelled ‘exists in different’ points to a text box that reads ‘states’. ‘States’ is joined to the ‘heat energy’ box by an arrow in the opposite direction, so that together the text boxes and arrow read ‘heat energy affects states’. Three downward arrows labelled ‘can be’ link ‘states’ to three boxes which read ‘solid’, ‘liquid’ and ‘gas’. ‘Solid’ connects by an arrow labelled ‘water is’ to ‘ice’. ‘Liquid’ connects by an arrow labelled ‘water is’ to ‘water vapour’.
