Level: 4 Curriculum info: Science, Knowledge, Physical World Keywords: physics concepts, energy, sound, ears, sequencing Description of task: Students place five statements in order to show how sound travels from its source to the brain. Making Better Sense: Sound Answers/responses: Y8 (05/2000) moderate Diagnostic and formative information: Common error Rotating the order of Vibrations cause our ear drum to vibrate and Ear bones vibrate (18% of students). Students should know that sound hits the ear drum (tympanun) which vibrates to move the ear bones (or auditory ossicle). Note: ear bones are three "tinybones" in the middle ear: the malleus (hammer); the incus (anvil); and the stapes (stirrup). Rotating the order of Vibrations pass on to air particles and Air particles carry vibrations (7% of students). Vibrations first need to pass on from the object to the air before the air particles carry the vibrations. Noise Meteor on the moon Sound experiences Making a sound gun Travelling sound
