Light - Reflection in a Plane Mirror - Find the Pair Game KS3

This is an engaging and enjoyable memory game on reflection in plane mirrors. Pupils work in teams of three or four. Each team lays out their 42 cards face down in a square and take it in turn to turn over two cards. If the cards are a question and its correct answer, the pupil keeps the pair. If they are not a match they are turned face down and the next pupil gets a turn. This process continues until all cards are matched and the winner is the pupil with the most pairs.

If a team member thinks that the selectors pair is not a correct match, they can challenge.
Pupils are encouraged to check their books for the correct answer but the teacher also has a quick-check answer sheet. If the challenge is correct, the challenger keeps the pair.
