Some students believe light helps, but is not necessary for vision.

Misconception RESEARCH REVIEW

Students sometimes believe it is possible for (all/some) people to see in pitch darkness (an idea more prevalent among city dwellers than the country) or cats to see in pitch darkness.

Resources to Address This

  • Totally in the dark! (5-11 and 11-14)

    Ref - SPT HS01 TA07 and Li01 TA01

    This activity allows pupils to enter a completely dark space, something which very few are likely to have previously experienced. Once in this light-free space they will recognise that it is impossible to see anything around them.
