Training of senses

Photo:
A girl is shaking a film container in order to identify the content of the container by means of the noise.

This photo shows a situation from a listening memory game. The game involves the ability to remember and recognize things.

Information and ideas:
This is how the game is played:
Different materials like sand, rice, dried peas, pebbles or stones, flour etc. are filled into empty film containers, two containers for each material. Now the players have to match the pairs by identifying the material inside the containers by shaking The whole game can be played with teams of two partners as well. Each player gets a film container and has to go round and compare the sounds made when the containers are shaken and thus find his or her partner.
(Tip: Label all the containers on the bottom,
for example with colored dots so that the pairs can be clearly recognized again.)

Sense organs stimuli

Photo:
At a fair, all sorts of stimuli affect our senses, for example, the smell of candy floss, the bright lights of the roundabouts etc.

If all our senses are attracted at the same time with the same degree of intensity, as at a fair, it can be a very pleasant experience but it can also be a strain.

Information and ideas:
The students can report on their own experiences, for example, what can I smell, see and hear at a fair?
What are the typical smells, tastes and sounds associated with Christmas?

Sense organ skin - sense of touch and of feel

Photo:
The skin as sense organ. A gigantic organ which we use to touch and to feel.

The biggest organ in the human body is the skin.
A twelve-year-old has an amount of skin equivalent to about 20 A4 pages.
The skin has several tasks:
To begin with, to protect against external influences; it can heal itself in the event of minor injuries. And then it is responsible for touching and feeling. We can distinguish between six different sensations: touch, pressure, pain, tension, vibration and temperature.

Information and ideas:
What sorts of things can I feel? Here, it is a good idea to prepare a box full of materials which can be recognised by touching and feeling them.

Sense organ of balance - position

Labeled graphic:
The cupola changes its shape when it is bent and stimulates the sensory hairs. The calcium carbonate crystals act as extra ballast.

The cupola (gelatinous mass) changes its shape when it is bent and stimulates the sensory hairs. The calcium carbonate crystals act as extra ballast. The lymph simply serves to absorb here.

Information and ideas:
This graphic is very useful for showing the function of the sense of position in the inner ear.

;: Echolocation with dolphins

Graphic:
Dolphins use the echo under water to locate other fish as prey.

Just like a bat, a dolphin can recognize from the echo whether the prey is nearby or not. It produces clicks and whistling noises under water. If it has discovered something of interest, the dolphin will move closer and "click" more quickly. This gives it an exact acoustical picture of its surroundings.

Information and ideas:
Based on the phenomenon of an echo, this graphic can show how animals use the echo to find prey.

The Ear, Hearing and Hearing Impairment: With eyes blindfolded

Photo:
To illustrate the topic "Seeing with your ears?.

When the sense of sight is not working, another sense can replace the eyes. We pick up a lot of information about our environment from our ears and can thus, in part, at least, substitute the sense of sight.

Information and ideas:
For example, students can try out themselves on a listening walk whether they can guess where they are.

The Ear, Hearing and Hearing Impairment: Sense organs - sense of feeling

Graphic:
How sensitively our skin reacts to temperatures can be seen in the sauna. After the heat, the cold gets our blood circulation going!

The skin gives us information about temperatures via receptors. As a rule, the heat in the sauna makes our blood pressure go down. The subsequent sensation of cold on the skin does not just stimulate the peripheral blood circulation. A reflex reaction via the autonomic nervous system causes our blood pressure to rise to the normal level again as well.

Information and ideas:
Use picture to introduce topic with the question "What can we feel with our skin?", e.g. cold, heat, wind etc.

The Ear, Hearing and Hearing Impairment; Teaching unit: How I hear; ; Teaching unit: Personal health care for the ear: Sense organ ear

Photo:
A close-up photo of an ear. As starting-point for studying the anatomy of the ear.

The ear as a sense organ contains the sense of hearing as well as the sense of position and the sense of rotation.

The sense of hearing is the only sense we have that never goes to sleep. The ear reacts seven times faster than the eye and can differentiate things much better than the nose.

Contribution to hearing:
The pinna is thought to have a funnelling function for sound waves. Unlike in some animals, this function is not particularly well-developed in human beings. If the pinna is in any way deformed or in the case of ears that stick out, the sense of hearing is not noticeably affected either way.
Completely missing pinna may affect hearing to the factor 2-3 depending on position relative to sound of source!

Information and ideas:
What are all the things I can hear? Here, it is a good idea to take the students on a listening walk or look at the effects of a roundabout.

My five senses

Graphic:
Drawing with labelling spaces for the five senses. Can be printed out or used with the projector.

What do our sense organs do?
- We use our eyes to see with,
- we use our nose to smell with,
- we use our ears to hear with,
- we use our tongue to taste with and
- we use our skin to touch with and feel.

Information and ideas:
The graphic can be printed out.
The students can then enter in the boxes what they can taste or hear.
Instead of words or text, small drawings, for example, can be drawn in (what I like to taste, smell or hear best of all) or small pictures cut out.

Sense organs - sense of taste

Photo:
A healthy person has about 4,000 taste buds spread over the tongue, the inside of the cheeks and the throat.

The fact that we can enjoy the taste of our food is the result of interaction between several senses. It is not just through our mouth that we get the messages referring to the taste of food and drink. Our so-called "chemical senses", the actual sense of taste and the sense of smell work together to provide human beings with the ability to recognize a wide range of different tastes and flavours. Scientists are of the opinion that the perception of taste can be trained in a similar way to the sense of smell. They claim that gourmets should be able to train their sense of taste in the same way that perfumiers can.

Information and ideas:
Students can have a tasting session and try to recognize different drinks by tasting them when they are blindfolded:
- Cola
- Water
- Tea
- Fruit juice
- etc.
