Biology KS3 & KS4: The human ear
This short film provides a journey into the ear, looking at hearing and balance, plus a real-life example of how the ear helps us to walk.
Key processes are shown, including the movement of ossicles against the oval window and the way that the semi circular canals sense orientation.
The 3D visuals are placed alongside real-life footage of a child learning to walk.
This short film is from the BBC series, Inside the Human Body.
As they watch this short film, students could keep a note of all the parts of the ear and create a diagram explaining each stage of the process.
An active demonstration of the vibrations travelling through the ear could be created in the classroom, with students lined up acting as different parts of the ear, then a vibration being transferred via movements down the line to reach the brain.
With regards to balance, students could perform exercises that disrupt their sense of balance, such as spinning around a certain number of times, and relating the unbalanced sensation afterwards to what is happening inside the ear at a cellular level.
This could be discussed in terms of confusion between different sensory information.
This short film will be relevant for teaching biology at KS3 and KS4/GCSE in England, Wales and Northern Ireland and National 4/5 in Scotland. Appears in AQA, OCR, EDEXCEL, CCEA, WJEC, SQA
