Each group can demonstrate one sound to the class, describing how the sound is produced. Use questions which will encourage students to experiment with some of the sounds. The process of creation or modification of a sound gives students a chance to practice their analytical abilities to determine what causes the sound and their creative abilities in refining and modifying the sound. Have the students sit at their desks and close their eyes. Ask them to listen very carefully and count the number of different sounds that they hear.
Students can then discuss the sounds that they heard.
Ask the students to do this exercise at home in various rooms and when they are outside in different locations. When they are outside, remind them to make sure that it is safe to close their eyes before doing so. When the students return to class, they can report on any interesting or unusual sounds which they heard. Put equal amounts of a material in each of two cans. Tape the opening shut.
