Sound is produced because of vibrations and these vibrations can be clearly felt when we touch the balloon attached. The balloon in turn vibrates the air inside the pipe and this is how the message is passed to the other end. Children also get to one of the modes of communication. • This is a recommended science project for grade 3 children.
