    In this activity, students investigate crystal shapes and crystal systems. Traditional ceramics are clay-based – clays have a mineral composition and minerals have a crystalline structure.

    By the end of this activity, students should be able to:

    • describe the main points of difference between a crystalline solid and an amorphous solid
    • recognise and identify at least 3 of the 7 crystal systems
    • use models to point out the angular and side length differences that characterise the cubic, triclinic and rhombohedral crystal systems
    • effectively use optical aids such as hand lenses and simple microscopes to view crystalline solids.
