Hearing Kim's Game
This version requires some preparation and a tape player. Make a cassette tape of 10 sounds that you would hear. This could be 10 nature sounds, or 10 city sounds, or a mixture of the two. Unlike the above versions, the girls record what they think they are hearing as they hear them. So, you play your first sound, and the girls are given 10 seconds to write down what they think it is, then you play the second sound, etc.
