Deer ears is a classic tool in nature awareness raising to extend your sense of hearing. Just put your hands behind your ears and form a bowl with each hand. You will be surprised on how much more you can perceive that way.
We thought of a variation to be done with groups (of children or youths):
Chinese whisper with deer ears.
How to play: All group members form a queue. This time put your hands to your head in front of your ears with the hand bowl facing backwards. The last person in the queue will start whispering a word to the person in front. The person in front then passes on what he/she has heard to her person in front and so on. After passing the queue check which word has been understood by the person first in the queue. AP
