Sound week 2 - Hearing

We worked this week on how our ears hear.
We started with a few simple activities - we first blindfolded a child and asked them to identify the location a sound was coming from, then blocked on ear and repeated and finished with a discussion on why two ears are better than one.


We discussed the structure of the ear, starting with the pinna (outer ear made from cartilage) - we talked about how they funnel sounds down into our inner ear and how bigger ears are better for catching sound. We played a pre-recorded sound and asked them to rate the volume out of 10, then repeated the process using a funnel (keeping the volume and distance from the ear the same).



Finally they made a working model of the inner ear

and labelled their diagrams.
