Write the word ‘atoms’ in the centre of the board, then write the words 'matter’, ‘elements’, ‘compounds’, ‘particles’, ‘structure’ and ‘John Dalton’, around them in a rough circle. Ask students to write down as many links as they can between the term ‘atoms’ and the words around it. Ask students to use a variety of resources to make an atomic model. The model should be three-dimensional and show the arrangement of the subatomic particles. Each group of students should be asked to produce models of a specific element. Students produce a range of models representing the nuclear atom and use it to describe how Dalton’s atomic model has changed. The following ideas should be highlighted to students: The mass and charge of the subatomic particles are too small for everyday use, so we use relative masses and charges. The nucleus of an atom is very small relative to the atom, which is mostly empty space. Digital: Inside the atom animation
