In this activity, students participate in an interactive ‘true or false’ activity that highlights common alternative conceptions about light and sight. This activity can be done individually, in pairs or as a whole class.

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

  • clarify some of their current views about light and sight
  • provide evidence to support their current views
  • debate ideas with others who hold different views that may challenge their current thinking
  • investigate some key light concepts including how light travels and how we see things.
