Biology The Human Ear   A mechanical model to demonstrate the working of the human ear     Subject Biology, physics Level Lower and upper secondary Language English Type Lesson sequence       Learning objective   Understanding the application of physical principles in operation of human ear.     Didactical comments   Pupils will do many questions about the apparatus (exploring and discovering). Making a model of human ear with simple materials, they will understand how the sounds transmit from the outer ear to the middle and inner ear. They will understand the working of basilar membrane in the cochlea which is a application of resonance and how the brain understand the different sounds.     Suggestions for methodology   Teacher teaches in front of the class, lectures.     Contact details   Name Ilias Kalogirou Email mail@ekfe.ilei.sch.gr       Last update: 14 December 2006 More Biology Teaching Ideas  •  Cucumber as a Cell (http://www.esa.int/SPECIALS/Science_on_Stage/SEMUYRC4VUE_0.html)  •  Discovering Animal Behaviour (http://www.esa.int/SPECIALS/Science_on_Stage/SEMMD6ARR1F_0.html)  •  Model Organisme in Teaching Life Sciences (http://www.esa.int/SPECIALS/Science_on_Stage/SEM0C8ARR1F_0.html)  •  Tick Patrol (http://www.esa.int/SPECIALS/Science_on_Stage/SEMP5C8OY2F_0.html)  •  CusMiBio (http://www.esa.int/SPECIALS/Science_on_Stage/SEMX8T8OY2F_0.html) Download  •  Human ear PDF (http://esamultimedia.esa.int/docs/scienceonstage/Human_ear_POS3.pdf)
