C3 Sense of hearing (teacher instructions)

Experimentation instructions for Experimento | 8+:
Background information on the content and practical information on conducting the "Sense of hearing? experiment, which comprises three subexperiments.

The teacher instructions include information on the following: the main question, relevance to the curriculum, skills, notes on conducting the subexperiments, the research group, further research assignments, and the reference to values.

The experiment comprises three subexperiments:
· Parade of ears
· Directional hearing
· Making loud noises quiet

Our sense of hearing is very important. However, we can lose it permanently, for example, through exposure to too much noise. Many children are unaware of this, and therefore it is important to sensitize them to their own, individual sense of hearing and to provide them with a better understanding of hearing.

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
· All materials mentioned in the instructions will have to be purchased directly from commercial sources.

The Ear, Hearing and Hearing Impairment;: The sounds during my day - a record

Worksheet:
Record template for entering the noises heard during the day with a distinction between disturbing and undisturbing noise situations.

In everyday life we are confronted with many different sorts of sound. Some we want, others are unwanted or actually disturbing and are thus perceived as "noise?. Some of these sources of noise can be avoided, others not.
Music, for example, is a wanted sound that we can regulate according to our wishes but that may in many cases be regarded as annoying and disturbing by other people. Noise from a construction site falls into the category of noise we do not want to hear.

Information and ideas:
Students should consciously experience the sounds they are confronted with during a day and enter them in a table. By keeping a written record, they recognize which sounds were "wanted? and which were "unwanted?. This can lead into a discussion of how to define noise.

Relevant for teaching:
Noise: causes, effect, protection
Noise consumption and leisure-time activities

Ultrasound localization bat

Website:
Visualization of the ultrasound localization system in bats.

Bats orientate themselves not with their eyes, but with their ears using ultrasound calls. They have an orientation system that is similar to radar. This system is so sensitive that it can even pick up fine wires only 0.1 mm in diameter. In flight, they emit localization calls through their mouths, in some species through their noses, and their large ears hear the echoes.

Information and ideas:
Explorative learning is supported.

Relevant for teaching:
Reception of impulses and information processing
Our senses open up our surroundings
Sound/acoustics: audible range, hearing limit
Communication, understanding

The Ear, Hearing and Hearing Impairment; Teaching unit: How I hear;: Experiments on hearing

Experimentation instructions:
Experiments on hearing which every student can easily do, for example, directional hearing with a tube.

The experiment cards provide instructions for the following experiments:
· Cover your ears
· Direction hearing with a hose
· Replicate the eardrum with paper and grains of sand
· Ringing of bells
The experiments can be done independently by the students, for example as station training/learning circle either alone or in small groups.
The results observed should be discussed together.

Information and ideas:
Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.

Relevant for teaching:
Structure and function of a sensory organ
Reception of stimuli and transmission of information
Communication
Acoustic phenomena
Vibrations and waves
