In this activity, learners investigate the sense of hearing and plan and conduct their own experiments. In "CLASS EXPERIMENT," learners discover how we are able to judge where a sound is coming from with our eyes closed, and whether this judgment is easier for noises coming from specific directions. In "TRY YOUR OWN EXPERIMENT," learners design new experiments, investigating, for example, if one ear is as good as two in locating sound sources; how the size and shape of the external ear affects hearing; or whether other learners know how to take care of their hearing. This lesson plan includes background information, tips for educators and separate guides for educators and learners.
