  • Reflection of light  (5-11)

    Ref - SPT HS01 PN06

    Light beams are reflected from surfaces according to the law of reflection, which states that 'the angle of incidence is equal to the angle of reflection'.  This activity concentrates on mirrors.

    The ideas are extended to other objects in the next activity.

  • Not just mirrors (11-14)

    Ref - SPT Li03PN04

    This takes the idea of reflection further and applies to objects that are not mirrors.
